1.1Cobbler

linux系統安裝服務，可以通過網絡啟動（PXE）方式快速安裝、重裝物理服務器和虛擬機，同時管理DNS、DHCP等。既可以使命令行方式管理，也可以給予web界面管理工具。同時提供API接口，可以方便二次開發使用，是較早的kickstart的升級版，比較容易配置，自帶web界面比較易於管理。

2.環境準備

[root@CentOS 7 ~]# cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

[root@CentOS 7 ~]# uname -r

3.10.0-327.el7.x86_64

[root@CentOS 7 ~]# getenforce

Disabled

[root@CentOS 7 ~]# systemctl status firewalld.service

● firewalld.service - firewalld - dynamic firewall daemon

3.部署Cobbler服務

3.1添加yum源

curl -o /etc/yum.repos.d/CentOS-Base.repo

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

3.2安裝相關服務

[root@CentOS 7 ~]# yum install -y cobbler cobbler-web dhcp tftp-server pykickstart httpd python-django

3.3修改/etc/cobbler/settings中的server項

[root@CentOS 7 ~]# sed -i 's#server: 127.0.0.1#server: 172.16.1.201#' /etc/cobbler/settings

3.4修改/etc/cobbler/settings中的next_server項

[root@CentOS 7 ~]# sed -i 's/next_server: 127.0.0.1/next_server: 172.16.1.202/' /etc/cobbler/settings

3.5下載所有需要的網絡啟動文件（需要先啟動cobbler服務，國外網站，下載速度巨慢，或者下載失敗）

cobbler get-loaders

3.6修改密碼

[root@CentOS 7 ~]# sed -ri "/default_password_crypted/s#(.*: ).*#\1\"`openssl passwd -1 -salt 'fengyu' '123456'`\"#" /etc/cobbler/settings

3.7配置Cobbler統一管理DHCP

root@CentOS 7 ~]# sed -i 's/manage_dhcp: 0/manage_dhcp: 1/' /etc/cobbler/settings

3.8防止誤重裝

[root@CentOS 7 ~]# sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings

3.9配置DHCP Cobbler模板

[root@CentOS 7 ~]# sed -i.ori 's#192.168.1#172.16.1#g;22d;23d' /etc/cobbler/dhcp.template

3.10啟動相關服務

[root@CentOS 7 ~]# systemctl start rsyncd

[root@CentOS 7 ~]# systemctl start tftp.socket

[root@CentOS 7 ~]# systemctl start cobblerd.service

[root@CentOS 7 ~]# cobbler sync
