自动化运维装机系统cobbler

cobbler作为一个自动化的操作系统安装管理平台，可以用于企业、数据中心中运维人员批量快速安装系统，不仅支持Windows、Linux，还支持ESXi系统等。本文主要讲解一下如何安装部署cobbler系统，然后通过cobbler来安装centos系统。

• 安装epel源

  yum install epel-release

• 安装相关组件

  yum install -y httpd dhcp tftp rsync syslinux cobbler cobbler-web pykickstart xinetd

#cobbler、tftp、httpd启动服务

systemctl start cobblerd tftp.socket httpd xinetd

systemctl enable cobblerd tftp.socket httpd xinetd

• 初始化cobbler

cobbler check

#修改主配置文件:

vi /etc/cobbler/settings，文件第273，384行

sed -i 's/server: 127.0.0.1/server: 172.18.20.80/' /etc/cobbler/settings

sed -i 's/server: 192.168.x.208/server: 10.x.x.208/' /etc/cobbler/settings

server: 172.18.20.80 # tftp服务器

next_server: 172.18.20.80 #cobbler服务器

• 开启tftp服务

vi /etc/xinetd.d/tftp

#修改参数

disable = no

sed -i 's/disable = yes/disable = no/' /etc/xinetd.d/tftp

• 下载网络引导文件

cobbler get-loaders

#开启rsync服务

systemctl start rsyncd && systemctl enable rsyncd

安装debmirror包

yum install debmirror -y

创建系统初始化后的root密码

opensslpasswd -1 -salt 'root' 'cobbler'

$1$root$0rfeHw7KuedF3BaESUWZm1

vi /etc/cobbler/settings

#修改参数

default_password_crypted: “$1$root$0rfeHw7KuedF3BaESUWZm1”

• 安装电源管理工具

yum install -y fence-agents

#重启cobbler服务，然后重新执行检查：

systemctl restart cobblerd

cobbler check

• 配置DHCP

#修改主配置文件：

vi /etc/cobbler/settings

#修改参数值为1

manage_dhcp: 1

sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings

修改配置文件：/etc/cobbler/dhcp.template

subnet 172.18.20.0 netmask 255.255.255.0 {

option routers            172.18.20.1;

option domain-name-servers 172.18.20.1;

option subnet-mask        255.255.255.0;

range dynamic-bootp        172.18.20.100 172.18.20.120;

default-lease-time         21600;

max-lease-time             43200;

next-server               $next_server;

• 配置rsync、tftp

vi /etc/cobbler/settings

manage_tftpd: 1

manage_rsync: 1

sed -i 's/manage_tftpd: 0/manage_tftpd: 1/' /etc/cobbler/settings

sed -i 's/manage_rsync: 0/manage_rsync: 1/' /etc/cobbler/settings

#grep'^next_server' /etc/cobbler/settings

#重启cobbler并使用sync同步

systemctl restart cobblerd

cobbler sync

开启
