利用Cobbler批量快速网络安装CentOS

Cobbler是什么？

Cobbler（补鞋匠）集成了PXE、DHCP、DNS、Kickstart服务管理和yum仓库管理工具，相对之前的 Kickstart 更加快捷、方便的批量布署Red Hat、CentOS类系统

测试环境：

VMware® Workstation : 9.0.0 build-812388

操作系统 : CentOS 5.6 32位

 

一.安装epel源  

1. [root@server1 ~]# wget http://dl.Fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm [root@server1 ~]# rpm -ivh epel-release-5-4.noarch.rpm
2. warning: epel-release-5-4.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6 Preparing... ########################################### [100%]
3. 1:epel-release ########################################### [100%] [root@server1 ~]#

安装epel源的好处 就是epel这个项目是由fedora维护的，在维护的这个源中包含许多软件，包括ntop，nagios之类的，也就是说，你安装了epel源就可以直接用yum install ntop来安装了，不过这个应该针对红帽企业版Linux(RHEL)及其衍生发行版(比如CentOS、Scientific Linux)系统，Ubuntu这类的应该不行。   二.安装与配置cobbler   1.安装cobbler和一些必须的包，并设置开机自动启动  

1. [root@server1 ~]# yum -y install cobbler httpd rsync tftp-server xinetd dhcp python-ctypes pykickstart cman ...
2. cobbler-2.2.2-1.el5.rf.noarch from rpmforge has depsolving problems --> Missing Dependency: python-netaddr is needed by package cobbler-2.2.2-1.el5.rf.noarch (rpmforge)
3. cobbler-2.2.2-1.el5.rf.noarch from rpmforge has depsolving problems --> Missing Dependency: mod_wsgi is needed by package cobbler-2.2.2-1.el5.rf.noarch (rpmforge)
4. Error: Missing Dependency: python-netaddr is needed by package cobbler-2.2.2-1.el5.rf.noarch (rpmforge) Error: Missing Dependency: mod_wsgi is needed by package cobbler-2.2.2-1.el5.rf.noarch (rpmforge)
5. You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems
6. package-cleanup --dupes rpm -Va --nofiles --nodigest

我的系统需要安装这2个包。  

1. [root@server1 ~]# wget ftp://rpmfind.net/linux/epel/5/i386/python-netaddr-0.5.2-1.el5.noarch.rpm [root@server1 ~]# rpm -ivh python-netaddr-0.5.2-1.el5.noarch.rpm
2. warning: python-netaddr-0.5.2-1.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6 Preparing... ########################################### [100%]
3. 1:python-netaddr ########################################### [100%] [root@server1 ~]# wget ftp://rpmfind.net/linux/epel/5/i386/mod_wsgi-3.2-2.el5.i386.rpm
4. [root@server1 ~]# rpm -ivh mod_wsgi-3.2-2.el5.i386.rpm warning: mod_wsgi-3.2-2.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
5. Preparing... ########################################### [100%] 1:mod_wsgi ########################################### [100%]

安装完成2个上面的包之后再次安装  

1. [root@server1 ~]# yum -y install cobbler httpd rsync tftp-server xinetd dhcp python-ctypes pykickstart cman ...中间省略
2. [root@server1 ~]# chkconfig httpd on
3. [root@server1 ~]# chkconfig cobblerd on [root@server1 ~]# chkconfig dhcpd on
4. [root@server1 ~]# chkconfig xinetd on [root@server1 ~]#/etc/init.d/iptables stop
5. [root@server1 ~]#chkconfig --level 35 iptables off

服务控制脚本  

1. [root@server1 ~]#chmod +x /etc/init.d/cobbler_all 用法：/etc/init.d/cobbler_all start|stop|startus|sync

脚本内容：  

1. #!/bin/bash
2. case $1 in start)
3. /etc/init.d/httpd start /etc/init.d/xinetd start
4. /etc/init.d/dhcpd start /etc/init.d/cobblerd start
5. ;; stop)
6. /etc/init.d/httpd stop /etc/init.d/xinetd stop
7. /etc/init.d/dhcpd stop /etc/init.d/cobblerd stop
8. ;; status)
9. /etc/init.d/httpd status /etc/init.d/xinetd status
10. /etc/init.d/dhcpd status /etc/init.d/cobblerd status
11. ;; sync)
12. cobbler sync ;;
13. *) echo "Input error,please in put 'start|stop|status|sync'!";
14. exit 2>&1 >/dev/null & ;;
15. esac
