cobbler自动化安装linux

Cobbler自动部署Linux

Cobbler简介

Cobbler是一个快速网络安装linux的服务，而且在经过调整也可以支持网络安装windows。该工具使用python开发，小巧轻便，使用简单的命令即可完成PXE网络安装环境的配置，同时还可以管理DHCP，DNS，以及yum包镜像。

Cobbler部署

环境准备：

systemctl stop firewalld

setenforce 0

sed -ri '/^SELINUX/c\SELINUX=disabled' /etc/selinux/config

yum -y install epel-release

yum -y install cobbler cobbler-web tftp-server dhcp httpd xinetd

systemctl start httpd cobblerd

systemctl enable httpd cobblerd

 

 

 

 

cobbler测试：

cobbler check

sed -ri '/allow_dynamic_settings:/c\allow_dynamic_settings: 1' /etc/cobbler/settings

设置cobbler可脚本

问题解决：

1.cobbler     setting          edit     --name=server     --value=192.168.11.16

2.cobbler     setting          edit     --name=next_server                 --value=192.168.11.16

3.sed -ri /selinux=enable/c\selinux=disable           /etc/selinux/config

4.sed -ri '/disable/c\disable = no' /etc/xinetd.d/tftp                 systemctl restart xinetd

   systemctl enable xinetd

5.cobbler get-loaders

6.systemctl start rsyncd

  systemctl enable rsyncd

7.不需要安装，不影响实验

8.openssl passwd -1 -salt 'openssl rand -hex 4' 'leo123'

  $1$openssl $JszVPeye1hqHPJ1njkxz20   //获取到的密码

 cobbler     setting          edit --name=default_password_crypted--value='$1$openssl$JszVPeye1hqHPJ1njkxz20'

9.yum install -y fence-agents

10.cobbler setting edit --name=manage_dhcp --value=1

vim  /etc/cobbler/dhcp.template

测试：（新建一台虚拟机开机）
