Cobbler自動部署Linux
Cobbler簡介
Cobbler是一個快速網絡安裝linux的服務，而且在經過調整也可以支持網絡安裝windows。該工具使用python開發，小巧輕便，使用簡單的命令即可完成PXE網絡安裝環境的配置，同時還可以管理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.不需要安裝，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）
