Managed Entities

Name Description
IIS Windows Process Activation Service (WAS)
Windows Process Activation Service (WAS) manages application pool configuration and the creation and lifetime of worker processes for HTTP and other protocols. The World Wide Web Publishing Service (W3SVC) and other services depend on WAS.

IIS Application Pool
An Internet Information Services (IIS) application pool is a grouping of URLs that is routed to one or more worker processes. Because application pools define a set of Web applications that share one or more worker processes, they provide a convenient way to administer a set of Web sites and applications and their corresponding worker processes. Process boundaries separate each worker process; therefore, a Web site or application in one application pool will not be affected by application problems in other application pools. Application pools significantly increase both the reliability and manageability of a Web infrastructure.

IIS Worker Process
An Internet Information Services (IIS) worker process is a windows process (w3wp.exe) which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool.

IIS Protocol Adapter
An Internet Information Services (IIS) protocol adapter is a Windows service that receives messages on a specific network protocol and communicates with The Windows Process Activation Service (WAS) to route incoming messages to the correct worker process.

IIS FTP Service
The Internet Information Services (IIS) FTP Service enables the Web server to be a File Transfer Protocol (FTP) server. If this service is stopped, the server cannot function as an FTP server.

IIS Web Management Service (WMSvc)
The Internet Information Services (IIS) Web Management Service (WMSvc) enables remote and delegated management of a Web server and its Web sites and applications.

IIS Application Host Helper Service (AppHostSvc)
The Internet Information Services (IIS) ApplicationHost Helper Service (AppHostSvc) enables IIS configuration history and application pool SID (security identifier) mapping. It enables the configuration history functionality by saving the ApplicationHost.config file to separate configuration history subdirectories at set intervals.

IISADMIN Service
The Internet Information Services (IIS) IISAdmin service hosts the IIS 6.0 configuration compatiblity component (metabase). The metabase is required to run IIS 6.0 administrative scripts, SMTP, and FTP.

IIS Hosted Web Core
The Internet Information Services (IIS) Hosted Web Core (HWC) is a low-level component that is used to run Web applications without the Windows Process Activation Service (WAS) or the built-in IIS configuration store (ApplicationHost.config).

IIS World Wide Web Publishing Service (W3SVC)
The Internet Information Services (IIS) World Wide Web Publishing Service (W3SVC), sometimes referred to as the WWW Service, manages the HTTP protocol and HTTP performance counters.

IIS Web Site
An Internet Information Services (IIS) Web site is a unique collection of Web pages and Web applications that is hosted on an IIS Web server. Web sites have bindings that consist of a port number, an IP address, and an optional host name or names.

Active Server Pages (ASP)
Active Server Pages (ASP) enables Web servers to dynamically generate Web pages and create interactive Web applications by using server-side scripting technology.



LVM mount 的问题


  摘要:Linux用户安装Linux操作系统时遇到的一个最常见的难以决定的问题就是如何正确地给评估各分区大小,以分配合适的硬盘空间。而遇到出现某个分区空间耗尽时,解决的方法通常是使用符号链接,或者使用调整分区大小的工具(比如PatitionMagic等),但这都只是暂时解决办法,没有根本解决问题。随着Linux的逻辑盘卷管理功能的出现,这些问题都迎刃而解,本文就深入讨论LVM技术,使得用户在无需停机的情况下方便地调整各个分区大小。
  
  一、前言
  
  每个Linux使用者在安装Linux时都会遇到这样的困境:在为系统分区时,如何精确评估和分配各个硬盘分区的容量,因为系统管理员不但要考虑到当前某个分区需要的容量,还要预见该分区以后可能需要的容量的最大值。因为如果估计不准确,当遇到某个分区不够用时管理员可能甚至要备份整个系统、清除硬盘、重新对硬盘分区,然后恢复数据到新分区。
  
  虽然现在有很多动态调整磁盘的工具可以使用,例如PartationMagic等等,但是它并不能完全解决问题,因为某个分区可能会再次被耗尽;另外一个方面这需要重新引导系统才能实现,对于很多关键的服务器,停机是不可接受的,而且对于添加新硬盘,希望一个能跨越多个硬盘驱动器的文件系统时,分区调整程序就不能解决问题。
  
  因此完美的解决方法应该是在零停机前提下可以自如对文件系统的大小进行调整,可以方便实现文件系统跨越不同磁盘和分区。幸运的是Linux提供的逻辑盘卷管理(LVM,LogicalVolumeManager)机制就是一个完美的解决方案。
  
  LVM是逻辑盘卷管理(LogicalVolumeManager)的简称,它是Linux环境下对磁盘分区进行管理的一种机制,LVM是建立在硬盘和分区之上的一个逻辑层,来提高磁盘分区管理的灵活性。通过LVM系统管理员可以轻松管理磁盘分区,如:将若干个磁盘分区连接为一个整块的卷组(volumegroup),形成一个存储池。管理员可以在卷组上随意创建逻辑卷组(logicalvolumes),并进一步在逻辑卷组上创建文件系统。管理员通过LVM可以方便的调整存储卷组的大小,并且可以对磁盘存储按照组的方式进行命名、管理和分配,例如按照使用用途进行定义:“development”和“sales”,而不是使用物理磁盘名“sda”和“sdb”。而且当系统添加了新的磁盘,通过LVM管理员就不必将磁盘的文件移动到新的磁盘上以充分利用新的存储空间,而是直接扩展文件系统跨越磁盘即可。
  
  二、LVM基本术语
  
  前面谈到,LVM是在磁盘分区和文件系统之间添加的一个逻辑层,来为文件系统屏蔽下层磁盘分区布局,提供一个抽象的盘卷,在盘卷上建立文件系统。首先我们讨论以下几个LVM术语:
  
  *物理存储介质(Thephysicalmedia)
  这里指系统的存储设备:硬盘,如:/dev/hda1、/dev/sda等等,是存储系统最低层的存储单元。
  
  *物理卷(physicalvolume)
  物理卷就是指硬盘分区或从逻辑上与磁盘分区具有同样功能的设备(如RAID),是LVM的基本存储逻辑块,但和基本的物理存储介质(如分区、磁盘等)比较,却包含有与LVM相关的管理参数。
  
  *卷组(VolumeGroup)
  LVM卷组类似于非LVM系统中的物理硬盘,其由物理卷组成。可以在卷组上创建一个或多个“LVM分区”(逻辑卷),LVM卷组由一个或多个物理卷组成。
  
  *逻辑卷(logicalvolume)
  LVM的逻辑卷类似于非LVM系统中的硬盘分区,在逻辑卷之上可以建立文件系统(比如/home或者/usr等)。
  
  *PE(physicalextent)
  每一个物理卷被划分为称为PE(PhysicalExtents)的基本单元,具有唯一编号的PE是可以被LVM寻址的最小单元。PE的大小是可配置的,默认为4MB。
  
  *LE(logicalextent)
  逻辑卷也被划分为被称为LE(LogicalExtents)的可被寻址的基本单位。在同一个卷组中,LE的大小和PE是相同的,并且一一对应。
  
   
  
  首先可以看到,物理卷(PV)被由大小等同的基本单元PE组成。
  
   
  
  一个卷组由一个或多个物理卷组成。
  
   
  
  从上图可以看到,PE和LE有着一一对应的关系。逻辑卷建立在卷组上。逻辑卷就相当于非LVM系统的磁盘分区,可以在其上创建文件系统。
  
  下图是磁盘分区、卷组、逻辑卷和文件系统之间的逻辑关系的示意图:
  
   
  
  和非LVM系统将包含分区信息的元数据保存在位于分区的起始位置的分区表中一样,逻辑卷以及卷组相关的元数据也是保存在位于物理卷起始处的VGDA(卷组描述符区域)中。VGDA包括以下内容:PV描述符、VG描述符、LV描述符、和一些PE描述符。
  
  系统启动LVM时激活VG,并将VGDA加载至内存,来识别LV的实际物理存储位置。当系统进行I/O操作时,就会根据VGDA建立的映射机制来访问实际的物理位置。
  
  三、安装LVM
  
  首先确定系统中是否安装了lvm工具:
  
  #rpm–qa|greplvm
  lvm-1.0.3-4
  
  如果命令结果输入类似于上例,那么说明系统已经安装了LVM管理工具;如果命令没有输出则说明没有安装LVM管理工具,则需要从网络下载或者从光盘装LVMrpm工具包。
  
  安装了LVM的RPM软件包以后,要使用LVM还需要配置内核支持LVM。RedHat默认内核是支持LVM的,如果需要重新编译内核,则需要在配置内核时,进入Multi-deviceSupport(RAIDandLVM)子菜单,选中以下两个选项:
  
    Multipledevicesdriversupport(RAIDandLVM)
    <*>Logicalvolumemanager(LVM)Support
  
  然后重新编译内核,即可将LVM的支持添加到新内核中。
  
  为了使用LVM,要确保在系统启动时激活LVM,幸运的是在RedHat7.0以后的版本,系统启动脚本已经具有对激活LVM的支持,在/etc/rc.d/rc.sysinit中有以下内容:
  
  #LVMinitialization
  if;then
  action$”SettingupLogicalVolumeManagement:”/sbin/vgscan&&/sbin/vgchange-ay
  fi
  
  其中关键是两个命令,vgscan命令实现扫描所有磁盘得到卷组信息,并创建文件卷组数据文件/etc/lvmtab和/etc/lvmtab.d/*;vgchange-ay命令激活系统所有卷组。
  
  四、创建和管理LVM
  
  要创建一个LVM系统,一般需要经过以下步骤:
  
  1、创建分区
  使用分区工具(如:fdisk等)创建LVM分区,方法和创建其他一般分区的方式是一样的,区别仅仅是LVM的分区类型为8e。
  
  2、创建物理卷
  创建物理卷的命令为pvcreate,利用该命令将希望添加到卷组的所有分区或者磁盘创建为物理卷。将整个磁盘创建为物理卷的命令为:
  
  #pvcreate/dev/hdb
  
  将单个分区创建为物理卷的命令为:
  
  #pvcreate/dev/hda5
  
  3、创建卷组
  创建卷组的命令为vgcreate,将使用pvcreate建立的物理卷创建为一个完整的卷组:
  
  #vgcreateweb_document/dev/hda5/dev/hdb
  
  vgcreate命令第一个参数是指定该卷组的逻辑名:web_document。后面参数是指定希望添加到该卷组的所有分区和磁盘。vgcreate在创建卷组web_document以外,还设置使用大小为4MB的PE(默认为4MB),这表示卷组上创建的所有逻辑卷都以4MB为增量单位来进行扩充或缩减。由于内核原因,PE大小决定了逻辑卷的最大大小,4MB的PE决定了单个逻辑卷最大容量为256GB,若希望使用大于256G的逻辑卷则创建卷组时指定更大的PE。PE大小范围为8KB到512MB,并且必须总是2的倍数(使用-s指定,具体请参考manvgcreate)。
  
  4、激活卷组
  为了立即使用卷组而不是重新启动系统,可以使用vgchange来激活卷组:
  
  #vgchange-ayweb_document
  
  5、添加新的物理卷到卷组中
  当系统安装了新的磁盘并创建了新的物理卷,而要将其添加到已有卷组时,就需要使用vgextend命令:
  
  #vgextendweb_document/dev/hdc1
  
  这里/dev/hdc1是新的物理卷。
  
  6、从卷组中删除一个物理卷
  要从一个卷组中删除一个物理卷,首先要确认要删除的物理卷没有被任何逻辑卷正在使用,就要使用pvdisplay命令察看一个该物理卷信息:
  
   
  
  如果某个物理卷正在被逻辑卷所使用,就需要将该物理卷的数据备份到其他地方,然后再删除。删除物理卷的命令为vgreduce:
  
  #vgreduceweb_document/dev/hda1
  
  7、创建逻辑卷
  创建逻辑卷的命令为lvcreate:
  
  #lvcreate-L1500–nwww1web_document
  
  该命令就在卷组web_document上创建名字为www1,大小为1500M的逻辑卷,并且设备入口为/dev/web_document/www1(web_document为卷组名,www1为逻辑卷名)。如果希望创建一个使用全部卷组的逻辑卷,则需要首先察看该卷组的PE数,然后在创建逻辑卷时指定:
  
  #vgdisplayweb_document|grep”TotalPE”
  TotalPE45230
  #lvcreate-l45230web_document-nwww1
  
  8、创建文件系统
  笔者推荐使用reiserfs文件系统,来替代ext2和ext3:
  
  
  
  创建了文件系统以后,就可以加载并使用它:
  
  #mkdir/data/wwwroot
  #mount/dev/web_document/www1/data/wwwroot
  
  如果希望系统启动时自动加载文件系统,则还需要在/etc/fstab中添加内容:
  
  /dev/web_document/www1/data/wwwrootreiserfsdefaults12
  
  9、删除一个逻辑卷
  删除逻辑卷以前首先需要将其卸载,然后删除:
  
  #umount/dev/web_document/www1
  #lvremove/dev/web_document/www1
  lvremove–doyoureallywanttoremove”/dev/web_document/www1″?:y
  lvremove–doingautomaticbackupofvolumegroup”web_document”
  lvremove–logicalvolume”/dev/web_document/www1″successfullyremoved
  
  10、扩展逻辑卷大小
  LVM提供了方便调整逻辑卷大小的能力,扩展逻辑卷大小的命令是lvcreate:
  
  #lvextend-L12G/dev/web_document/www1
  lvextend–extendinglogicalvolume”/dev/web_document/www1″to12GB
  lvextend–doingautomaticbackupofvolumegroup”web_document”
  lvextend–logicalvolume”/dev/web_document/www1″successfullyextended
  
  上面的命令就实现将逻辑卷www1的大小扩招为12G。
  
  #lvextend-L 1G/dev/web_document/www1
  lvextend–extendinglogicalvolume”/dev/web_document/www1″to13GB
  lvextend–doingautomaticbackupofvolumegroup”web_document”
  lvextend–logicalvolume”/dev/web_document/www1″successfullyextended
  
  上面的命令就实现将逻辑卷www1的大小增加1G。
  
  增加了逻辑卷的容量以后,就需要修改文件系统大小以实现利用扩充的空间。

So I recently had to mount and old drive on my laptop because I thought I had a drive failure (turns out it was actually the mobo). So bought a 14$ USB drive enclosure from Newegg and proceeded to try to mount the old drive on my laptop. The problem I ran into was that both the old drive and the drive in my laptop where using LVM and both Volume groups had the same name of VolGroup00. This of course meant that I couldn’t easily mount the new drive (/dev/sdb). However, we can just rename the old drives Volume group. The first step is to grab the UUID of the second group:

[root@localhost /]# vgscan
Reading all physical volumes. This may take a while…
WARNING: Duplicate VG name VolGroup00: Existing 3eRTge-6Qdv-Uc3N-n7rT-HtpD-juW5-fsVna0 (created here) takes precedence over E54jfp-1X0X-qCwZ-SrAS-VYit-bXcM-a8lmtx
Found volume group “VolGroup00″ using metadata type lvm2
Found volume group “VolGroup00″ using metadata type lvm2

The UUID in this case is E54jfp-1X0X-qCwZ-SrAS-VYit-bXcM-a8lmtx so next we rename it with vgrename:

[root@localhost /]# vgrename E54jfp-1X0X-qCwZ-SrAS-VYit-bXcM-a8lmtx Whoami00
WARNING: Duplicate VG name VolGroup00: Existing 3eRTge-6Qdv-Uc3N-n7rT-HtpD-juW5-fsVna0 (created here) takes precedence over E54jfp-1X0X-qCwZ-SrAS-VYit-bXcM-a8lmtx
Volume group “VolGroup00″ successfully renamed to “Whoami00″

After this I rebooted because Fedora 9 kept insisting that Whoami00 was actually still my primary drive. The reboot fixed that.

So after doing that we’re good to go almost, but the Volume group is still marked as unavailable:

[root@localhost ~]# lvdisplay
— Logical volume —
LV Name /dev/Whoami00/LogVol00
VG Name Whoami00
LV UUID uL2cZp-35jq-qp5H-U1In-2XgT-kYdG-274lq6

LV Write Access read/write
LV Status NOT available
LV Size 1.00 GB
Current LE 32
Segments 1
Allocation inherit

To fix that we simply run vgchange again to mark this volume as active:

[root@localhost ~]# vgchange -a y Whoami00
2 logical volume(s) in volume group “Whoami00″ now active
[root@localhost ~]# lvdisplay
— Logical volume —

# open 0
LV Size 73.41 GB
Current LE 2349

Read ahead sectors auto
- currently set to 256
Block device 253:2

After that you can go ahead and mount the volume and your good to go:

[root@localhost ~]# mount /dev/Whoami00/LogVol00 /mnt/
[root@localhost ~]# cd /mnt/
[root@localhost mnt]# ls
backup dev lib misc opt proc selinux sys var

客户之前安装的系统是LVM分区格式( /dev/hdc2),现在又重新装了一个系统也是LVM分区的(/dev/hda2),现在想把 /dev/sda1 挂载到现在的硬盘上。

2:集中多服务管理,在一个VZCC内可以对多个VPS,VPS模版,VE,以及备份进行管理。

3:备份功能的增强. 可进行备份的计划任务,选择性备份,增量备份,不间断服务备份。可以把windows的备份保存到linux备份服务器上,也可以把linux 的备份保存到windows备份服务器上。

4:VZP2V :现在可以把 windows 2000和2003都迁移到VPS内运行。

5:模版的改进:

6:角色也许可的管理

7:Improved Support for Multiple Ethernet Network Interfaces – The ability to manage
multiple NICs from both the browser-based and GUI tools. The multiple NICs may be used to
create redundancy with multiple connections to a single VE, and they may be configured to
different networks and VLANs to direct or control network traffic and access.

需要做的测试如下:

1:性能方面的测试:主要是压力测试

2:迁移管理:从硬件到VPS内,从VPS到VPS

3:备份策略:

概述
Virtuozzo采用了操作系统虚拟化技术来实现将一台物理服务器的操作系统划分成为多个相互隔离、独立的操作系统。作为一个成熟可靠的在国内外有广泛应用的产品,完整的灾备方案是必不可少的。本文将介绍搭建VZ备份网络的两种主要方案。

备份与恢复
Virtuozzo提供了备份与恢复工具可对单个VPS或是多个VPS进行备份和恢复操作。备份与恢复的操作形式为命令行、VZCC界面或是VZMC界面。在命令行下,使用vzbackup和vzrestore命令可以执行备份和恢复。在VZMC下,点击单个VPS,在弹出的选择备份节点的选项中执行备份即可。在VZCC上,只能进行本机的VPS备份,不能进行远程的备份,所以只能适用于部分场合。

1:映射共享磁盘备份方案

整体架构

vituozzo.jpg

2. 技术特点
文件共享服务器:在本方案中,首先部署一台文件共享服务器用于集中备份的数据存放。这台文件共享服务器可以是Windows平台,使用微软标准的文件共享;也可以是Linux服务器,使用Samba提供文件共享。
多个共享帐号:文件共享服务器上建议创建多个名字不同的共享,并且设置上不同的权限,分别挂接到相应的VZ硬件节点。不建议所有的硬件节点都采用一个共享帐号,这样会导致相应的安全问题。
映射网络驱动器:VZ硬件节点挂接文件共享服务器的形式采用映射本地磁盘驱动器的形式。Windows上可以使用系统内置的映射驱动器功能,Linux上可以修改fstab并添加相应的mount命令将文件共享直接映射为本地的目录。
本地VPS备份:备份的过程为管理员到相应的硬件节点上执行备份操作。为此管理员需要登陆每一个硬件节点,分别做备份操作。进行VPS备份时候,操作类型是本地备份,即备份到本机,但是存放备份文件的目标目录其实是一个映射的网络驱动器,备份数据通过网络直接写入到了远程的文件共享服务器。这种操作形式,由硬件节点把数据写往集中存储机,可以理解为对数据的“推送”操作或是“顶”操作。

多重计划任务:由于本方案要登陆每个硬件节点分别执行操作,所以添加计划任务的时候,也需要到每个硬件节点上添加自己的计划任务。设置多个计划任务会相对比较复杂,操作量比较大。
安全性:采用本方案需要定期对文件共享服务器做备份转移处理。这是因为硬件节点对分配给它的共享目录有写权限,所以如果硬件节点被攻击成为了跳板,则攻击者可以读写相应的共享目录,清除其中的备份。所以,每过一段时间,在文件共享服务器上需要有计划任务将备份好的文件转移到非共享目录方可确保安全。

备份节点远程备份方案

1. 整体架构

vzbackup.jpg

2. 技术特点
VZ备份节点:在本方案中,部署一台或者多台的VZ服务器用于备份,作为备份节点。备份节点服务器上也需要安装Virtuozzo,当通过命令行进行操作的时候,备份节点无须配置许可证,只要装好软件即可作为备份节点。但如果通过VZMC进行操作,则需要至少配置一个供测试用的临时许可证,否则VZMC会无法连接到服务器。
多系统备份节点:VPS在Windows系统上和Linux系统上的实现有着很大不同,所以如果要备份的网络中分别有Windows服务器和Linux服务器,则需要架设两台以上的备份服务器,Windows备份节点负责备份Windows网络,Linux备份节点负责备份Linux网络。这是本方案的一个主要缺点,即可能会需要多于一台备份机。
远程VPS备份:备份的过程为管理员登陆到备份节点进行操作。管理员在备份节点上执行相应的命令,备份节点的VZbackup将会连接到要备份的服务器上,查找要备份的VPS信息,并执行备份操作。备份后的数据并不保存在源服务器上,而是保存在了集中备份服务器的硬盘上。在本方案下,管理员不需要一一登陆硬件节点,只要在备份节点执行命令即可,操作相对简单。备份操作是有备份节点发起的,连接到目标服务器后获取数据并下载回来,这中操作的形式可以理解为“拖拉”操作,或者“GET”操作。
多重计划任务:由于本方案只要在备份节点上执行操作即可,所以添加计划任务,也只要在备份节点上执行就可以了。但是由于备份时候会产生相应的网络占用,所以建议对每个服务器的备份时间错开少许,避免网络压力过大。除此之外,如果要备份的VPS体积过于巨大,也不建议采用本方案,比如备份数十GB的VPS很可能因为网络同步过程中发生超时而备份失败。所以对于十分大型的应用建议采用第一种备份方式更为直接可靠。
安全性:采用本方案相对前一方案有着很高的安全性。运行VZ的硬件节点对于备份文件的存储服务器不能发起任何操作,备份工作是由备份节点主动发起的,并通过vzbackup命令从专门的通道传输,所以备份文件相对存储更安全。

4:灾难恢复:首先 操作系统安装,磁盘挂载,数据转移,启动服务 这几个步骤

1.
操作系统安装。
在原服务器损坏后,首先更换硬件并新装系统。新装系统的全部过程,请参考相应的安装手册。安装过程中请注意操作系统版本、安装方式、分区大小、系统参数尽可能和原服务器保持一致

2.
Virtuozzo for Linux安装。
在新系统上,安装Virtuozzo for Linux 。请注意,安装的版本需要与原系统一致,例如原系统是3.x版本,则新服务器也需要安装3.x版本,不可安装2.6或4.0等其他版本。

3.
挂载磁盘
在将原数据磁盘挂载到新的服务器的过程中,如果原服务器使用了LVM逻辑卷管理方式,则需要使用LVM的命令来挂载,分别执行pvscan/vgscan/lvscan来查找逻辑卷,识别出来后,才能用mount进行挂载。如果原的磁盘没有使用LVM逻辑卷管理方式,则直接将设备符号如/dev/sdb1 mount到目录即可完成挂载。

在服务器上建立一个新的目录以便挂载。
[root@vz ~]# mkdir /mnt/sdb1

执行mount命令挂载数据。
[root@vz ~]# mount /dev/sdb1 /mnt/sdb1

停止正在运行的Virtuozzo服务。
[root@vz ~]# /etc/init.d/vz stop

要先设置cp命令参数,否则下边的复制中会反复提示文件重复。
[root@vz ~]# alias cp=’cp’

复制原数据磁盘上的/etc/vz*到当前系统上
[root@vz3 ~]# cp -prf /mnt/sdb1/etc/vz* /etc

复制原数据磁盘上的/etc/sysconfig/vz*到当前系统上
[root@vz ~]# cp -prf /mnt/sdb1/etc/sysconfig/vz* /etc/sysconfig

使用cp -af 命令复制数据目录。注意,必须用-af参数。
[root@vz ~]# cp -af /mnt/sdb1/vz /

复制完毕后,取消对磁盘的挂载。
[root@vz ~]# umount /mnt/sdb1

5.
启动服务。
启动Virtuozzo服务。
Starting Virtuozzo: [ OK ]
Bringing up interface venet0: [ OK ]
Configuring interface venet0: [ OK ]
Loading Virtuozzo license: [ OK ]
Set vzprivrange: [ OK ]

Configuring Virtuozzo accounting: [ OK ]
Starting VE 1: [ OK ]
Setup offline management for VE 101: [ OK ]
Setup offline management for VE 102: [ OK ]
Setup offline management for VE 103: [ OK ]
Setup offline management for VE 104: [ OK ]
Setup offline management for VE 105: [ OK ]
Setup offline management for VE 106: [ OK ]
Setup offline management for VE 107: [ OK ]
Setup offline management for VE 108: [ OK ]
Setup offline management for VE 109: [ OK ]
Setup offline management for VE 110: [ OK ]
[root@vz ~]#
至此恢复完成。

二:、
Virtuozzo for Windows 灾难恢复

在针对Virtuozzo for Windows服务器做灾难恢复时候,可以简单的采用系统盘重新安装,数据盘保留原位的方法。

1.
前提
在安装Virtuozzo for Windows的过程中,根据安装文档及其他教程所述,一般将Virtuozzo的程序目录安装在“C:\Program Files\SWsoft” ,将数据目录安装在“D:\vz”目录,将数据的备份目录安装在“D:\vz\backups”目录下。程序目录安装位置对数据恢复没有影响,但数据目录和备份目录需要特别记录原安装路径,然后按照本文操作。

2.
操作系统重装。
首先重新安装Windows系统,在安装过程中,选择删除C盘系统盘,并重新格式化整个C盘。如果程序目录在“C:\Program Files\SWsoft”,即便删除了C盘也没有关系,新安装Virtuozzo会补充程序目录下所有丢失的文件。存放数据和备份的D盘不要修改,并请注意操作前要再三确认,以免误操作删除了数据。

3.
原路径安装Virtuozzo for Windows 。
在安装Virtuozzo for Windows的过程中,会要求选择程序目录、数据目录、备份目录。此时程序目录选择在C盘或者D盘或者其他地方没有关系,和原系统路径不一直也没关系,但数据目录和备份目录必须和磁盘上原路径一致。

4.
识别VPS
安装Virtuozzo for Windows 完成后,即可看到原来的VPS已经被列出。

5. 其余工作
为了确保Virtuozzo基础平台和原服务器一致,请更新Windows补丁(Windows会自动提示安装),即可完成整体的数据恢复。

8 top tips for IE 7


Don’t like the way Internet Explorer 7 looks or works? Then change it. There are plenty of ways you can hack it, tweak it or just make it simpler to use.In this article, you’ll find out how to speed up IE’s display of Web sites, build your own Search Bar engine, get control over how IE prints Web pages, navigate with several essential keyboard shortcuts and more. These tips work in both Windows XP and Windows Vista. Some of the tips are quite simple to perform, while others are more advanced. Some even require Registry hacks.

Important: If you’re unfamiliar with Registry editing — if you’re not certain you know how to create a new DWORD value, for example — read our story “The tweaker’s guide to the Windows Registry” first. Be sure to read the instructions for backing up the Registry before you attempt any Registry edits whatsoever.

8 top tips for IE 7

 


1. Add your own search engine to IE

IE 7 comes with a variety of built-in search providers you can choose from the Search Bar in the browser’s upper right-hand corner. It’s easy to add more by clicking the down arrow on the far right of the bar, choosing Find More Providers and then adding them from the page that appears.

But you’re not stuck with the list of search providers (also called engines) that Microsoft supplies. You can build your own search engine and use it in IE’s Search Bar to search through any site, no matter where you are on the Internet.

Note that this site doesn’t have to be a search engine per se; any Web site that has search functionality will do. If you frequently look up items on sports, shopping or travel sites, for instance, you can create a search engine for that site and add it to the options in IE 7’s Search Bar.

First, click the down arrow on the far right of the Search Bar, and choose Find More Providers. On the right-hand side of the page that appears, you’ll see a Create Your Own section, as shown below.

Create your own search
Fill in this form to build your own customized search provider for IE.

In another tab, open up the site for which you want to create a search engine to use inside IE. In our example, we’ll use www.computerworld.com.

In the site’s search box, type in the word TEST, making sure to use all capital letters. After you do the search, copy the resulting URL from the Address Bar and paste it into the first field in the Create Your Own box on the page you’ve opened in your first tab.

New search added
The new search engine is in place and ready to go.

In our example, the URL is:http://www.computerworld.com/action/googleSearch.do?
cx=014839440456418836424%3A-khvkt1lc-e&q=TEST&
cof=FORID%3A9#1150

Then, in the next field in the Create Your Own section, type in a name for your search engine. In our example, we’ll call it Computerworld.

Click the Install button to install the new search provider into IE. You’ll get a prompt asking you to confirm that you want to add it. Click Add Provider.

Note that the prompt gives the correct name of the site you’re going to add, but next to From: it says www.microsoft.com instead of the site you chose. However, www.microsoft.com won’t appear in the search engine you add.

Your new provider will now be available for you. Click the down arrow to the right of the Search Bar, and it will appear in the list of options, as you can see to the right. Use it as you would any other search engine.

2. Speed up IE’s Web page loading

By default, IE allows only two simultaneous download sessions from a single Web server. This can affect the speed of your Web browsing, because you’re not able to simultaneously download all the objects that make up a Web page, so the page displays more slowly. If you could force IE to download more objects at once, Web pages would display more quickly.

A tweak to the Windows Registry does the trick. With this tweak, you can force IE to use more than two simultaneous sessions. A good number is 10. Here’s how to do it:

  1. Run the Registry Editor by typing regedit at a command line or in the Windows Vista Start Search box.
  2. Go to HKEY_CURRENT_USER\Software
    \Microsoft\Windows\CurrentVersion
    \Internet Settings
    .
  3. Choose Edit –> New –> DWORD Value.
  4. Create a new DWORD value called MaxConnectionsPer1_0Server, and give it a value of 10.
  5. Choose Edit –> New –> DWORD Value, create another DWORD value called MaxConnectionsPerServer, and give it a value of 10.

    (Note: If you want to experiment with fewer or more than 10 simultaneous connections, change the value in both DWORD values accordingly.)

  6. Exit the Registry and close IE. When you restart IE, the new value will be in effect and your Web browsing should speed up.

3. Get multiple tabs under control

Anyone who’s tried tabbed browsing knows it’s vastly superior to the old way of browsing, with a separate window for each Web site you’re looking at. But once you get going, it’s easy to get lost in a sea of tabs.

IE 7 includes a couple of shortcuts to help you find the right tab easily. To see a grid of thumbnails of all your open tabs, click the Quick Tabs button that appears to the left of the tabs. Or to see a drop-down list of all the open tabs, click the Tab List button (it looks like a down arrow) immediately to the right of the Quick Tabs button.

QuickTabs and Tab list buttons
The Quick Tabs button is at the far left, the Tab List button to its right.

Want to close all the tabs you have open except the one you’re currently on? It’s simple. Just right-click the tab you want to keep open and choose Close Other Tabs from the pop-up menu.

Tab Settings dialog
Changing the tab settings to make the tabs warning vamoose.

Finally, what about that annoying “Do you want to close all tabs?” warning that pops up whenever you try to shut down IE with multiple tabs open?It’s easy to make that warning vanish forever. Next time you see it pop up, click Show Options, check the box marked Do not show me this dialog again and click the Close Tabs button.

Or to take care of this now without waiting until the next time you exit IE with multiple tabs open, follow these steps:

  1. Click the Tools button and select Internet Options.
  2. From the dialog box that appears, click the General tab and then click Settings in the Tabs section.
  3. From the screen that appears (shown to the right), uncheck the box next to Warn me when closing multiple tabs.
  4. Click OK and OK again. The warning will no longer appear.4. Tweak your way to better printing with IE

    IE 7 gives you a great deal of control over how your Web pages print, including whether to print a header or footer, what to put in the header and footer, whether to print thumbnails of Web pages and more.

    Changing printing options is simple. Click the down arrow next to the printer icon at the top of IE and choose Print Preview. A screen like the one shown below appears.

    The Print Preview screen
    The Print Preview screen.

    Icons across the top of the page control how the page will print. They’re straightforward and self-explanatory, and include options such as printing in landscape or portrait mode, shrinking the printout so it fits nicely on the sheet of paper, and controlling whether headers and footers appear on the printout.

    For example, to turn headers and footers on and off, click the fifth icon from the left, or press Alt-E. The preview display will change to reflect whether the headers and footers will print. Click the printer icon on the page when you’ve got the page set up however you want.

    If you’d like, you can tweak what actually appears on the headers and footers when they print. On the Print Preview screen, click the Page Setup icon (it looks like a gear). The Page Setup dialog box, shown below, appears.

    Page Setup dialog box
    Customize headers and footers with the Page Setup dialog box.

    The Header and Footer input boxes tell IE what to print in the header and footer. By default, this is what is in the Header box:

    &w&bPage &p of &P

    This tells IE to print the window title (&w); print the word “Page” and align it and the rest of the text to the right (&bPage); leave a space and print the page number ( &p); and leave another space and print the total number of pages ( &P).

    This is what’s in the Footer box:

    &u&b&d

    This tells IE to print the URL (&u), and print the date in short-date format (&b&d).

    For example, if you were visiting the New England Patriots home page (www.patriots.com) on Nov. 20, 2007, the window title was “Official Web site of the New England Patriots,” and the Web page was two printed pages long, the header would print out like this:

    Official Web site of the New England Patriots Page 1 of 2

    The footer would print out like this:

    http://www.patriots.com 11/20/2007

    By changing the text and code in the Header and Footer input boxes on the Page Setup dialog box, you can change what prints out in the header and footer.

    Header and footer printing codes

    Variable

    What it prints

    &w Window title
    &u URL of the current page
    &d Date in short format (4/16/2007)
    &D Date in long format, including the day of the week (Monday, April 16, 2007)
    &t Time in 12-hour clock format (5:26:43 PM)
    &T Time in 24-hour clock format (17:26:43 PM)
    &p Current page number
    &P Total number of pages
    &b Right aligns the following text
    &b &b Centers the text between &b and &b
    && An ampersand (&)

    The codes you can use, and what they’ll print, are shown in the table to the left.You can combine these codes with any text that you enter. So let’s say you entered this into the Header box on the Page Setup dialog box:

    I visited the &w on &D

    If you went to the Patriots’ home page on Tuesday, Nov. 20, 2007, and printed it out, this would be the header:

    I visited the Official Web site of the New England Patriots on Tuesday, Nov. 20, 2007

    Let’s say you entered this into the Footer box:

    I printed Page &p at &T

    It would print this:

    I printed Page 1 at 17:26:43 PM

    5. Change the IE window title

    Take a look in the upper left-hand corner of the IE title bar. What do you see? Most likely the name of the site you’re visiting, followed by “Windows Internet Explorer,” or possibly “Internet Explorer brought to you by” followed by the name of your hardware manufacturer. Maybe you don’t want to see that hardware manufacturer name there, or perhaps you want to put your own branding on the title — your own name or the name of your company.

    It’s easy to do, using the Registry Editor. Here’s how:

  5. Run the Registry Editor by typing regedit at a command line or the Windows Vista Start Search box.
  6. Go to HKEY_CURRENT_USER\Software
    \Microsoft\Internet Explorer\Main
    .
  7. Look for the String value named Window Title. If one doesn’t exist, create it by choosing Edit –> New –> String Value and naming it Window Title.
  8. Double-click the Window Title value, and in the Value Data field, type in the text that you want to appear in IE’s title bar. Click OK.
  9. Exit the Registry and close IE. When you restart IE, the new title will appear.

6. Get around IE fast with keyboard shortcuts

Mousing and clicking in IE can slow you down. A much better bet is to use keyboard shortcuts. The following tables list some of the most useful ones.

General and navigation shortcuts

Keyboard shortcut

What it does

Toggle full-screen mode F11
Find a word or phrase Ctrl-F
Open the current Web page in a new window Ctrl-N
Print the current page Ctrl-P
Zoom In Ctrl-+ (Ctrl and the plus sign)
Zoom Out Ctrl– (Ctrl and a hyphen)
Return to 100% view Ctrl-0
Go to your home page Alt-Home
Go backward one page Alt-Left Arrow
Go forward one page Alt-Right Arrow
Refresh the current page Ctrl-R or F5
Stop downloading the current page Esc

Tab shortcuts

Keyboard shortcut

What it does

Open a new tab Ctrl-T
Open a link in a new tab in the background Ctrl-click
Open a link in a new tab in the foreground Ctrl-Shift-click
Close a tab (it will close IE if only one tab is open) Ctrl-W or Ctrl-F4
Open Quick Tab view Ctrl-Q
Display a drop-down list of all open tabs Ctrl-Shift-Q
Switch to the next tab Ctrl-Tab
Switch to the previous tab Ctrl-Shift-Tab

Address Bar shortcuts

Keyboard shortcut

What it does

Jump to the Address Bar and select the URL Alt-D
Add http://www. to the beginning and .com to the end of text you enter in the Address Bar Ctrl-Enter
Open the selected URL in a new tab Alt-Enter
Display a drop-down list of addresses you’ve previously visited F4

Search Bar shortcuts

Keyboard shortcut

What it does

Go to the Search Bar Ctrl-E
Display a list of all of your search providers Ctrl-Down Arrow (with your cursor already in the Search Bar)
Open search results in a new tab Type search term, hit Alt-Enter

7. Put the Menu Bar where it belongs

To many people’s chagrin, the Menu Bar apparently vanished in IE 7. To turn it on temporarily, press the Alt key. To turn it on permanently, choose Tools –> Menu Bar.

Even when you do that, though, something looks odd. Unlike in earlier versions of IE, the Menu Bar appears underneath the Address Bar, rather than on top of it. With a Registry tweak, though, you can fix that:

  1. Run the Registry Editor by typing regedit at a command line or the Windows Vista Start Search box.
  2. Go to HKEY_CURRENT_USER\Software
    \Microsoft\Internet Explorer\Toolbar
    \WebBrowser
    .
  3. Choose Edit –> New –> DWORD Value.
  4. Create a new DWORD value called ITBar7Position and give it a value of 1.
  5. Exit the Registry, close IE, then restart it. The Menu Bar will now be at the top.

The Menu Bar below the Address Bar
The Menu Bar above the Address Bar
By default, the Menu Bar appears below the Address Bar, but you can put it on top where it belongs.


8. Manage your IE add-ons

There are plenty of add-ons (also called browser extensions) that can give IE new features, such as the Google Toolbar or ieSpell spell checker. But they can also cause problems, such as system conflicts, crashes or slowdown.

You can easily manage and troubleshoot them by turning them on or off:

  1. Select Tools –> Manage Add-Ons –> Enable or Disable Add-Ons.
  2. You’ll come to a screen like the one shown below. Highlight any add-on and select the Disable radio button near the bottom of the screen, and you’ll disable it.

If you’re running into frequent IE crashes, this is a great way to track down the source of your problem. Selectively turn on and off add-ons until you find the one that’s causing your problems.

Manage Add-Ons dialog
Use this screen to manage and troubleshoot your IE add-ons.

If you want to run IE with all add-ons disabled temporarily, go to a command line or the Run box (in Windows XP) or the Start Search box (in Windows Vista), and type iexplore.exe -extoff, then press Enter. This disables all your add-ons for the current browsing session only; the next time you run IE they’ll be back.
