SystemImager安装

安装环境

SystemImager服务器：CentOS release5.5 (Final) x86_64“Image-Server”

SystemImager客户端：CentOS release5.4 (Final) x86_64 ”Image-Client“

一 安装perl模块

1 下载模块安装包

Perl模块下载地址为：

http://search.cpan.org/~abw/AppConfig-1.66/

http://search.cpan.org/~chorny/MLDBM-2.04/

http://search.cpan.org/~grantm/XML-Simple-2.18/

下载的模块安装包为

AppConfig-1.66.tar.gz

MLDBM-2.04.tar.gz

XML-Simple-2.18.tar.gz

2 将包上传至vm中的SystemImager服务器端

将上述软件包下载到本机后用SecureCRT_CN上传到SystemImager服务器端

3 安装perl模块

chmod+x AppConfig-1.66.tar.gz

# tarzxf AppConfig-1.66.tar.gz

# cdAppConfig-1.66

#perl Makefile.PL

#make && make install

chmod+x MLDBM-2.04.tar.gz

# tarzxf MLDBM-2.04.tar.gz

# cdMLDBM-2.04

#perl Makefile.PL

#make && make install

chmod+x XML-Simple-2.18.tar.gz

# tarzxf XML-Simple-2.18.tar.gz

# cdXML-Simple

#perl Makefile.PL

#make && make install

二 给SystemImager Server端安装SystemImager软件

mkdir–p /home/systemimager

cd /home/systemimager

下载脚本install

wgethttp://download.systemimager.org/pub/sis-install/install

chmod+x install

./install-v --download-only systemconfiguratorsystemimager-common systemimager-x86_64boot-standard systemimager-x86_64initrd_template systemimager-server

#以上命令是x86_64操作系统下载的软件包

systemconfigurator-2.2.11-1.noarch.rpm

systemimager-common-4.0.2-1.noarch.rpm

systemimager-x86_64boot-standard-4.0.2-1.noarch.rpm

systemimager-x86_64initrd_template-4.0.2-1.noarch.rpm

systemimager-server-4.0.2-1.noarch.rpm

#如果是32位的OS则运行如下命令去下载软件包

./install-v --download-only systemconfigurator systemimager-common systemimager-i386boot-standardsystemimager-i386initrd_template systemimager-server

#下载的软件包为

systemimager-common-4.0.2-1.noarch.rpm

systemimager-server-4.0.2-1.noarch.rpm

systemimager-i386boot-standard-4.0.2-1.noarch.rpm

systemimager-i386initrd_template-4.0.2-1.noarch.rpm

如果不用install脚本下载软件包也可以使用下列链接

wget http://sourceforge.net/projects/systemconfig/files/systemconfigurator/2.2.11/systemconfigurator-2.2.11-1.noarch.rpm/

wgethttp://sourceforge.net/projects/systemimager/files/systemimager/4.0.2/systemimager-common-4.0.2-1.noarch.rpm

wgethttp://sourceforge.net/projects/systemimager/files/systemimager/4.0.2/systemimager-server-4.0.2-1.noarch.rpm

wgethttp://sourceforge.net/projects/systeminstaller/files/systeminstaller/1.04/systeminstaller-1.04.tar.gz

wget http://sourceforge.net/projects/systemimager/files/systemimager/4.0.2/systemimager-x86_64boot-standard-4.0.2-1.noarch.rpm/download

wgethttp://sourceforge.net/projects/systemimager/files/systemimager/4.0.2/systemimager-i386boot-standard-4.0.2-1.noarch.rpm

安装软件包

rpm -ivh --nodeps *.rpm

安装完以后的默认路径

/usr/lib/systemimager

/usr/sbin/si_cpimage

/usr/sbin/si_rmimage

/usr/sbin/si_mvimage

/usr/sbin/si_getimage

/usr/libexec/gthumb-image-viewer

/usr/bin/si_lsimage

/usr/bin/pdfimages

/var/lib/systemimager

/var/lib/systemimager/images

/var/lock/systemimager

/var/log/systemimager

/etc/systemimager

/etc/systemimager/systemimager.conf

/etc/systemimager/getimage.exclude

重启xinetd

servicexinetd stop

servicexinetd start

或者

servicexinetd restart

三 在客户端安装Systemimager软件，用来生成映像

mkdir –p /home/systemimager

cd /home/systemimager

下载install脚本

wget http://download.systemimager.org/pub/sis-install/install

chmod +x install

下载安装包到

./install -vsystemimager-client systemimager-commonsystemimager-x86_64initrd_template

安装软件包

cd /home/systemimager/

rpm-ivh --nodeps *.rpm

安装完以后的目录为

/etc/systemimager/updateclient.local.exclude

/etc/systemimager/client.conf

/etc/systemimager/updateclient.local.exclude.orig

/usr/sbin/si_prepareclient

/usr/sbin/si_updateclient

在client端启动rsync

运行以下命令只需要输入两次”y”即可

/usr/sbin/si_prepareclient –server “Image-Server”

查看rsync是否启动

ps aux |grep rsync

netstat –anpt |grep rsync

四 在SystemImager服务器上创建黄金客户端的系统镜像

现在我们已经准备好复制黄金客户端磁盘上的内容到SystemImager服务器，镜像将被存储在SystemImager服务器上的/var/lib/SystemImager目录，通过下面的命令检查并确认你在这个目录下有足够的磁盘空间：

#df -h /var/lib/systemimager

文件系统 容量 已用 可用 已用% 挂载点

/dev/mapper/VolGroup00-LogVol00 93G3.1G 86G 4% /

如果没有足够的空间容纳黄金客户端磁盘内容的拷贝，在你使用getimage命令时加上-directory选项，或这在/etc/SystemImager/SystemImager.conf 文件中修改镜像文件默认的存储位置“DEFAULT_IMAGE_DIR =/var/lib/systemimager/images”

看一下是否安装DHCP，如果没有的话需要安装

# rpm -qa |grep dhcp

# /usr/sbin/si_getimage-golden-client “Image-Client” image Zoho-CentOS5.4-Image

Thisprogram will get the " Zoho-CentOS5.4-Image " system imagefrom “Image-Client”

makingthe assumption that all filesystems considered part

ofthe system image are using ext2, ext3, jfs, FAT, reiserfs, or xfs.

Thisprogram will not get /proc, NFS, or other filesystems

notmentioned above.

***********************************WARNING ***********************************

Allfiles retrieved from a golden client are, by default, made accessible to

anyonewho can connect to the rsync port of this machine. See rsyncd.conf(5)

fordetails on restricting access to these files on the imageserver. See the

systemimager-sshpackage for a more secure (but less effecient) method of

makingimages available to clients.

***********************************WARNING ***********************************

See"getimage -help" for command line options.

IPAddress Assignment

---------------------

Thereare three ways to assign IP addresses to the client systems on an

ongoingbasis:

1)DHCP

----------------------------------------------------------------

A DHCP server will assign IP addresses toclients installed with

this image.They may be assigned a different address each time.

If you want to use DHCP, but must ensurethat your clients

receive the same IP address each time, see"man si_mkdhcpstatic".

2)STATIC

----------------------------------------------------------------

The IP address the client uses duringautoinstall will be

permanently assigned to that client.

3)REPLICANT

----------------------------------------------------------------

Don't mess with the network settings in thisimage. I'm using

it as a backup and quick restore mechanismfor a single machine.

Whichmethod do you prefer? [1]: 1

Youhave chosen method 1 for assigning IP addresses.

Areyou satisfied? ([y]/n): y

XMLin()requires either XML::SAX or XML::Parser at /usr/lib/systemimager/perl/SystemImager/Server.pmline 1587

查看一下生成的镜像

[root@sd images]# ls/var/lib/systemimager/images/Zoho-CentOS5.4-Image

bin bootdev etc homelib

查看生成镜像的大小

[root@sd images]# du -shZoho-CentOS5.4-Image

1.5G Zoho-CentOS5.4-Image

至此克隆的第一步已经完成，在上面的几个步骤中首先是配置服务器，其次是配置客户端。
最后进行了镜像制做
