cobbler自動化安裝linux

Cobbler自動部署Linux

Cobbler簡介

Cobbler是一個快速網絡安裝linux的服務，並且在通過調整也能夠支持網絡安裝windows。該工具使用python開發，小巧輕便，使用簡單的命令便可完成PXE網絡安裝環境的配置，同時還能夠管理DHCP，DNS，以及yum包鏡像。

Cobbler部署

環境準備：

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測試：

cobbler check

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

設置cobbler可腳本

問題解決：

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.不須要安裝，不影響實驗

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

  $1$openssl $JszVPeye1hqHPJ1njkxz20   //獲取到的密碼

 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

測試：（新建一臺虛擬機開機）
