cobbler 安装部署

最近机房要上线几个机柜的机器,必须实现自动化装机。

一、安装

系统环境是centos6.4,采用yum安装:

rpm -Uvh http://mirrors.hustunique.com/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum -y install cobbler  cobbler-web  httpd rsync tftp-server xinetd dhcp python-ctypes debmirror pykickstart

二、配置

1、关闭防火墙和SELinux 后重启系统:

/etc/init.d/iptables stop         #关闭防火墙
chkconfig iptables off
sed -i '/SELINUX=/d' /etc/selinux/config &&  echo "SELINUX=disabled">> /etc/selinux/config  #关闭SELINUX

2、修改cobbler配置文件:

'next_server: 127.0.0.1' 替换成 'next_server:172.28.26.188'    #DHCP服务地址
'server: 127.0.0.1' 替换成 'server: 172.28.26.188'   #cobbler服务地址
'manage_dhcp: 0' 替换成 'manage_dhcp: 1'      #cobbler管理dhcp
'manage_rsync: 0' 替换成 'manage_rsync: 1'     #cobbler管理rsync功能
default_password_crypted: "$1$cobber$yV9XfOuaaiVDvImopK7o.1"  
sed -i 's/next_server: 127.0.0.1/next_server: 172.28.26.188/g' /etc/cobbler/settings
sed -i 's/server: 127.0.0.1/server: 172.28.26.188/g' /etc/cobbler/settings
sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings
sed -i 's/manage_rsync: 0/manage_rsync: 1/g' /etc/cobbler/settings
sed -i 's/http_port: 80/http_port: 9080/g' /etc/cobbler/settings

openssl passwd -1 -salt "cobber" "123456 #把生成的密码填到/etc/cobbler/settings配置里default_password_crypted:生成的新密码,这个密码就是装完系统后的root密码。

3、修改tftp服务和rsync服务配置 :

sed -i '/disable/c disable = no' /etc/xinetd.d/tftp    #设置 'disable' 为 'no'
sed -i -e 's/= yes/= no/g' /etc/xinetd.d/rsync        #设置 'disable' 为 'no'

4、修改dhcp模板 :

subnet 192.168.66.0 netmask 255.255.255.0 {
     option routers             192.168.66.87;
     option domain-name-servers 202.106.0.20;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.66.100 192.168.66.102;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;
     class "pxeclients" {
     .....

5、修改cobbler-web配置 

sed -i 's/module = authn_denyall/module = authn_configfile/g' /etc/cobbler/modules.conf   #修改认证
htdigest  /etc/cobbler/users.digest "Cobbler" cobbler  #修改cobbler WEB页面管理密码

6、启动相关的服务

/etc/init.d/httpd start
/etc/init.d/xinetd start
/etc/init.d/dhcpd start
/etc/init.d/cobblerd start
chkconfig --level 35 httpd on
chkconfig --level 35 xinetd on
chkconfig --level 35 dhcpd on
chkconfig --level 35 cobblerd on

7、效验cobbler安装条件:

service cobblerd restart
cobbler get-loaders       #修复cobbler check时出现的错误信息
cobbler check

三、导入镜配置:

1:使用光盘镜像
挂载ISO镜像到/mnt目录
mount -o loop /data/CentOS_6.4_vm.iso /mnt/
导入ISO,并设置为“x86_64”,并将其命名为Centos6.4
cobbler import --path=/mnt/   --name=CentOS_6.4  --arch=x86_64

2:挂载linux光盘:
mount /dev/cdrom /media/
cobbler import --path=/media/CentOS_6.4_Final --name=Centos6.4
查看导入结果
cobbler distro list
完成后同步所有配置
cobbler sync

这时,我们就可以访问cobbler的web界面了:

四、需要装系统的机器从网卡启动:
