Cobbler 部署

环境介绍

Cobbler 操作系统: Centos-7.2-x86_64
Cobbler服务器地址: 10.90.0.10

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

Kickstart Metadata             : {}

在装机时设置Centos7网卡为eth0

[root@node1 ~]# cobbler profile edit --name=Centos-7.2-x86_64 --kopts='net.ifnames=0 biosdevname=0'

设置完成使用cobbler sync进行同步配置
