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：
ks.cfg：
#set $swap= $getVar('$swap', '2000')
autostep --autoscreenshot
install
url --url=$tree
# If any cobbler repo definitions were referenced in the kickstart profile, include them here.
