cobbler多机定制安装
1. cobbler服务端部署
服务端IP是192.168.32.125
#开始前确保防火墙色selinux永久是disable状态
#确保配置好yum源，包括epel源
#安装cobbler以及相关软件
[root@localhost ~]# yum -y install httpd dhcp tftp python-ctypes cobbler xinetd cobbler-web pykickstart net-tools
#启动服务并开机自启
[root@localhost ~]# systemctl enable --now httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@localhost ~]# systemctl enable --now cobblerd
Created symlink from /etc/systemd/system/multi-user.target.wants/cobblerd.service to /usr/lib/systemd/system/cobblerd.service.
[root@localhost ~]# systemctl enable --now rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
#cobbler服务器的ip，应设置为本机的ip，不能设为0.0.0.0，它不是监听地址
[root@localhost ~]# sed -i ‘s/^server: 127.0.0.1/server: 192.168.32.125/‘ /etc/cobbler/settings
#next_server选项用于DHCP / PXE，作为下载网络启动文件的TFTP服务器的IP。通常与服务器设置相同的IP。
[root@localhost ~]# sed -i ‘s/^next_server: 127.0.0.1/next_server: 192.168.32.125/‘ /etc/cobbler/settings
#开启TFTP
[root@localhost ~]# sed -i ‘/disable/s/yes/no/g‘ /etc/xinetd.d/tftp
#下载缺失文件
[root@localhost ~]# cobbler get-loaders

#通过cobbler check 核对当前设置是否有问题
[root@localhost ~]# 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系统的缺包错误，请忽略
#配置cobbler dhcp
#修改cobbler配置文件，让cobbler控制dhcp

2. 客户端安装
给客户端插上电源，连接上网线，开机。选择系统安装
3. 定制安装配置
定制安装步骤：
统计服务器mac地址
配置cobbler
安装
CentOS7: 00:50:56:36:2E:88
rhel-8: 00:50:56:26:F3:26
给两台服务器定制安装，一台装CentOS7,一台装rhel8
在 cobbler 的web界面上配置：
登录
#/var/lib/cobbler/config/systems.d/test1.json就是web界面的配置
[root@localhost ~]# cd /var/lib/cobbler/config/systems.d/
[root@localhost systems.d]# ls
test1.json
[root@localhost systems.d]#
[root@localhost systems.d]# cat test1.json

重启服务
[root@localhost systems.d]# systemctl restart cobblerd
[root@localhost systems.d]# systemctl restart httpd
[root@localhost systems.d]# systemctl restart xinetd
配置已经有了
4. 安装
两台机器开机自动安装各自的系统
client1开机
正在装包
登录，查看系统版本信息
client2开机
装包
配置内核
