Cobbler体验小记

Cobbler有人称之为装系统神奇，当你用了之后你会发现确实如此哈，下记录一下使用过程：

一、安装

我系统环境是centos6.4，采用yum安装：

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
'http_port: 80'替换成 'http_port: 9080'     #更改端口号9080
default_password_crypted: "$1$1111$vZEjq1D9/uNasiTXwyx4o."  #修改这个默认密码,因为运行cobbler check时会提示你修改密码, 用这个命令实现"openssl passwd -1 -salt '任意字母' '你的密码' "
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 '1234312' 'navy123456'    #把生成的密码填到/etc/cobbler/settings配置里default_password_crypted:生成的新密码

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 ：

vim /etc/cobbler/dhcp.template
subnet 172.28.26.0 netmask 255.255.255.0 {     #修改为自己需求网段
option routers             172.28.26.188;                 #修改自己的路由
option domain-name-servers 172.28.26.188;    #域名服务器地址
option subnet-mask         255.255.255.0;         #子网掩码
range dynamic-bootp        172.28.26.191 172.28.26.193;    #分配IP地址段
filename                   "/pxelinux.0";
default-lease-time         21600;
max-lease-time             43200;
next-server                $next_server;
}

5、修改cobbler-web配置 ：

sed -i 's/Listen 80/Listen 9080/g' /etc/httpd/conf/httpd.conf  #修改hhtp端口为9080
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
vim  /etc/httpd/conf.d/ssl.conf     #修改ssl配置,把下面几行添加到配置后面即可


RewriteEngine on
RewriteRule ^(.*) https://%{SERVER_NAME}/%{REQUEST_URI} [R,L]

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：

挂载ISO镜像到/mnt目录
mount -o loop /data/kisops_centos6.3._vm.iso /mnt/
导入ISO，并设置为“x86_64”，并将其命名为Centos6.3。（注：具体可查看/var/www/cobbler/ks_mirror/Centos6.4-x86_64/目录文件生成情况。)
cobbler import --path=/mnt/   --name=Centos6.3  --arch=x86_64
查看导入结果
cobbler distro list
完成后同步所有配置
cobbler sync

四、需要抓系统的机器从网卡启动就可以了

PS：附加一下ks.cfg
