关闭防火墙、selinux然后重启一下虚拟机

配置yum源

[root@server ~]# curl -o /etc/yum.repos.d/CentOS7-Base-163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@server ~]# sed -i 's/\$releasever/7/g' /etc/yum.repos.d/CentOS7-Base-163.repo
[root@server ~]# sed -i 's/^enabled=.*/enabled=1/g' /etc/yum.repos.d/CentOS7-Base-163.repo
[root@server ~]# yum -y install epel-release
安装过程略。。。

安装cobbler以及相关的软件

[root@server ~]# yum -y install httpd dhcp tftp python-ctypes cobbler  xinetd cobbler-web pykickstart
安装过程略。。。

启动服务并设置开机自启

[root@server ~]# systemctl start httpd.service 
[root@server ~]# systemctl start cobblerd.service 
[root@server ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@server ~]# systemctl enable cobblerd.service 
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.
//修改server的ip地址为本机ip
[root@server ~]# sed -i 's/^server: 127.0.0.1/server: 192.168.102.11/' /etc/cobbler/settings
//设置tftp的ip地址为本机ip
[root@server ~]# sed -i 's/^next_server: 127.0.0.1/next_server: 192.168.102.11/' /etc/cobbler/settings
//开启tftp
[root@server ~]# sed -i '/disable/s/yes/no/g' /etc/xinetd.d/tftp

下载缺失文件

[root@server ~]# cobbler get-loaders

此时可以在游览器上访问https://192.168.102.11/cobbler_web

启动rsync并设置开机自启

[root@server ~]# systemctl start rsyncd
[root@server ~]# 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@server ~]# openssl passwd -1 -salt "$RANDOM" 'wangqing123!'
$1$16884$gNXHahIREtcHhmHVTxzGF.            //这是密码加密后的形式

//将新生成的加密密码加入到配置文件

[root@server ~]# vim /etc/cobbler/settings
。。。
default_password_crypted: "$1$16884$gNXHahIREtcHhmHVTxzGF."
。。。

重启cobbler

[root@server ~]# systemctl restart cobblerd.service 
[root@server ~]# ss -antl
State       Recv-Q Send-Q Local Address:Port               Peer Address:Port

通过cobbler check核对当前设置是否有问题

[root@server ~]# 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

登入：账号密码都为cobbler

设置manage_dhcp为1

配置dhcp

[root@server ~]# vim /etc/cobbler/dhcp.template
subnet 192.168.102.0 netmask 255.255.255.0 {
     option routers             192.168.102.11;
     option domain-name-servers 192.168.102.11;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        192.168.102.100 192.168.102.120;
     default-lease-time         21600;
     max-lease-time             43200;
     next-server                $next_server;

重启服务并同步配置，改完dhcp必须要sync同步配置

[root@server ~]# systemctl restart cobblerd
[root@server ~]# cobbler sync
