部署 Cobbler
-
安装 Centos epel 原
[root@node1 ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
-
安装软件&启动服务
[root@node1 ~]# yum install httpd dhcp tftp python-ctypes cobbler cobbler-web pykickstart fence-agents [root@node1 ~]# systemctl start cobblerd.service [root@node1 ~]# systemctl enable httpd [root@node1 ~]# systemctl start httpd # 下载cobbler相关组件 [root@node1 ~]# cobbler get-loaders 出现*** TASK COMPLETE ***字符表示下载成功 检查需要修改的配置：由于不同的环境，提示会不一样，只需要安装提示内容一一解决即可 -
检查需要修改的配置：由于不同的环境，提示会不一样，只需要安装提示内容一一解决即可。
[root@localhost ~]# cobbler check The following are potential configuration items that you may want to fix: 1 : The 'server' field in /etc/cobbler/settings must be set to something other than localhost, or kickstarting features will not work. This should be a resolvable hostname or IP for the boot server as reachable by all machines that will use it. 2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings must be set to something other than 127.0.0.1, and should match the IP of the boot server on the PXE network. 3 : change 'disable' to 'no' in /etc/xinetd.d/tftp 4 : enable and start rsyncd.service with systemctl 5 : debmirror package is not installed, it will be required to manage debian deployments and repositories 6 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one Restart cobblerd and then run 'cobbler sync' to apply changes. 解决第一个和第二个提示：设置cobbler地址和设置dhcp服务器地址 [root@node1 ~]# vim /etc/cobbler/settings next_server: 10.90.0.10 server: 10.90.0.10 第三个和第四个提示解决：启动tftp和rsyncd服务 [root@node1 ~]# yum -y install tftp-server xinetd 启用tftp服务： [root@node1 ~]# vim /etc/xinetd.d/tftp disable = no 启动xinetd服务: [root@node1 ~]# systemctl enable rsyncd.service [root@node1 ~]# systemctl enable xinetd [root@node1 ~]# systemctl start xinetd.service [root@node1 ~]# netstat -nulp | grep xinetd udp 0 0 0.0.0.0:69 0.0.0.0:* 3659/xinetd 第5个可以不用解决 debian系统 第六个提示解决:设置cobbler密码，同时也是安装服务器的登录密码 [root@node1 ~]# openssl passwd -1 -salt 'Tczaflw@521' 'Tczaflw@521' $1$JM/i5ygv$cLMbz2ud00P6KI9XiEGj10 修改cobbler把生成的密码放入配置文件 [root@node1 ~]# vim /etc/cobbler/settings default_password_crypted: "$1$JM/i5ygv$cLMbz2ud00P6KI9XiEGj10" [root@node1 ~]# cobbler check 只剩下5即可 -
Cobbler管理DHCP服务器配置
-
编辑cobbler配置文件，开启cobbler管理dhcp
[root@node1 ~]# vim /etc/cobbler/settings manage_dhcp: 1 -
编辑cobbler的dhcp管理模版，设置dhcp分配的网段，网管，dns信息
[root@node1 ~]# vim /etc/cobbler/dhcp.template subnet 10.90.0.0 netmask 255.255.0.0 { option routers 10.90.0.10; option domain-name-servers 114.114.114.114; option subnet-mask 255.255.0.0; range dynamic-bootp 10.90.0.100 10.90.0.200; -
同步cobbler配置：同步之前先重启cobbler保证所有配置生效
[root@node1 ~]# systemctl restart cobblerd.service [root@node1 ~]# cobbler sync
-
-
Cobbler导入镜像
-
挂载iso文件到系统
[root@node1 ~]# mount /dev/cdrom /mnt -
导入镜像文件到cobbler
