安装cobbler以及相关软件

[root@linfan ~]#  yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web pykickstart

启动服务并设置开机自启动

[root@linfan ~]#  systemctl start httpd
[root@linfan ~]# systemctl start cobblerd
[root@linfan ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@linfan ~]# systemctl enable cobblerd
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.

修改server的ip为本机ip

[root@linfan ~]# sed -i 's/^server: 127.0.0.1/server: 192.168.24.168/' /etc/cobbler/settings  

设置tftp的ip地址为本机ip

sed -i 's/^next_server: 127.0.0.1/next_server: 192.168.24.168/' /etc/cobbler/settings

启动rysnc并设置开启自启动

root@linfan ~]# systemctl start rsyncd
[root@linfan ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.

生成加密的密码

[root@linfan ~]# openssl passwd -1 -salt "$RANDOM" 'linfan123'
$1$22895$x1tfkN/VsYusTzt449H.L. 

将新生成的加密密码加入配置文件

[root@linfan ~]# sed -i 's/default_password_crypted/#default_password_crypted/g' /etc/cobbler/settings
[root@linfan ~]# echo "default_password_crypted:  "$1$22895$x1tfkN/VsYusTzt449H.L."" >> /etc/cobbler/settings

通过cobbler check 核对当前设置

[root@linfan ~]# cobbler check
The following are potential configuration items that you may want to fix:

1 : debmirror package is not installed, it will be required to manage debian deployments and repositories
2 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them

Restart cobblerd and then run 'cobbler sync' to apply changes.

以上两个是关于debian系统的错误,请忽略

配置cobbler dhcp

修改cobbler配置文件,让cobbler控制dhcp

[root@linfan ~]#  sed -i '/^manage_dhcp/s/
0/1/g' /etc/cobbler/settings
[root@linfan ~]# sed -n '/^manage_dhcp/p' /etc/cobbler/settings
manage_dhcp: 1

配置dhcp

[root@linfan ~]#sed -i 's/subnet 192.168.1.0/subnet 192.168.24.0/g'  /etc/cobbler/dhcp.template
[root@linfan ~]# sed -i 's/option routers             192.168.1.5;/option routers             192.168.24.168;/g' /etc/cobbler/dhcp.template
[root@linfan ~]# sed -i 's/option domain-name-servers 192.168.1.1;/option domain-name-servers 192.168.24.168;/g' /etc/cobbler/dhcp.template

[root@linfan ~]#  sed -i 's/range dynamic-bootp        192.168.1.100 192.168.1.254;/range dynamic-bootp        192.168.24.100 192.168.24.150;/g' /etc/cobbler/dhcp.template     

重启服务并同步配置,改完dhcp必须要先sync同步配置
