Cobbler 简易自动安装系统

cobbler 配置安装

先安装 epel-release 包

为后续内容做准备

[root@localhost ~]# yum -y install epel-release
Running transaction
  正在安装    : epel-release-7-11.noarch                                    1/1 
  验证中      : epel-release-7-11.noarch                                    1/1 

已安装:
  epel-release.noarch 0:7-11                                                    

完毕！

再安装 cobbler 包

使用 yum 会自动帮助你处理依赖关系

[root@localhost ~]# yum -y install cobbler
已安装:
  cobbler.x86_64 0:2.8.5-0.3.el7                                                

作为依赖被安装:
  python-cheetah.x86_64 0:2.4.4-5.el7.centos                                    
  python-pygments.noarch 0:1.4-10.el7                                           
  python2-markdown.noarch 0:2.4.1-4.el7                                         
  python2-pyyaml.noarch 0:3.10-0.el7                                            
  python2-simplejson.x86_64 0:3.10.0-2.el7                                      
  tftp-server.x86_64 0:5.2-22.el7                                               

完毕！

接着再装一堆装机需要用的包

cobbler-web 网页形式去管理
dhcp dhcp服务
tftp-server 放压缩内核和引导文件
pykickstart 安装模板自动安装
httpd 需要用到检测
rsync 远程同步管理
xinetd 管理远程同步平台

[root@localhost ~]# yum -y install cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd
已安装:
  cobbler-web.noarch 0:2.8.5-0.3.el7     dhcp.x86_64 12:4.2.5-79.el7.centos    
  xinetd.x86_64 2:2.3.15-14.el7         

作为依赖被安装:
  apr-util-openssl.x86_64 0:1.5.2-6.el7                                         
  mod_ssl.x86_64 1:2.4.6-93.el7.centos                                          
  python-django-bash-completion.noarch 0:1.11.27-1.el7                          
  python2-django.noarch 0:1.11.27-1.el7                                         

更新完毕:
  httpd.x86_64 0:2.4.6-93.el7.centos         rsync.x86_64 0:3.1.2-10.el7        

作为依赖被升级:
  dhclient.x86_64 12:4.2.5-79.el7.centos                                        
  dhcp-common.x86_64 12:4.2.5-79.el7.centos                                     
  dhcp-libs.x86_64 12:4.2.5-79.el7.centos                                       
  httpd-tools.x86_64 0:2.4.6-93.el7.centos                                      
  mod_session.x86_64 0:2.4.6-93.el7.centos                                      

完毕！

修改 cobbler 主配置文件

先找到主配置文件位置，一般在 /etc 下

[root@localhost ~]# rpm -qc cobbler |grep /etc
……省略一堆
/etc/cobbler/rsync.exclude
/etc/cobbler/rsync.template
/etc/cobbler/secondary.template
/etc/cobbler/settings          #这个就是主配置文件了
/etc/cobbler/tftpd.template
/etc/cobbler/users.conf
/etc/cobbler/users.digest
/etc/cobbler/version
……再省略一堆

修改主配置文件

[root@localhost ~]# vim /etc/cobbler/settings
 末行模式分别搜索 next_server
                           server
                           manage_dhcp
 修改以下配置，服务指向本机，dchp改成1，表示开启
next_server: 20.0.0.140
server: 20.0.0.140
manage_dhcp: 1   ###这边一定一定一定一定一定记得空格，我这个一开始没加空格报错查了我一个小时

开启服务，关闭防护

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]# iptables -F
[root@localhost ~]# systemctl start httpd
[root@localhost ~]# systemctl start cobblerd

修改tftp配置

 [root@localhost ~]# vim /etc/xinetd.d/tftp 
        disable                 = no

修改 rsync 同步配置文件

让 rsync开机启动，之后重启 cobbler 服务，修改密码

[root@localhost ~]# systemctl enable rsyncd
Created symlink from /etc/systemd/system/multi-user.target.wants/rsyncd.service to /usr/lib/systemd/system/rsyncd.service.
[root@localhost ~]# systemctl restart cobblerd
[root@localhost ~]# openssl passwd -1 -salt '123123' '123123'
$1$123123$MAV.kVI/b3swmFLErPD2b0
上面的密码字符串记得要复制

[root@localhost ~]# vim /etc/cobbler/settings 
搜索 /default_password，改成这样，删了本来的密码，把你的字符串黏贴上去
default_password_crypted: "$1$123123$MAV.kVI/b3swmFLErPD2b0"

修改 cobbler 中的dhcp配置

[root@localhost ~]# vim /etc/cobbler/dhcp.template 
subnet 20.0.0.0 netmask 255.255.255.0 {
     option routers             20.0.0.2;
     option domain-name-servers 20.0.0.140;
     option subnet-mask         255.255.255.0;
     range dynamic-bootp        20.0.0.100 20.0.0.253;
[root@localhost ~]# cobbler sync    #同步

下载引导文件

记得开http服务，这边报错也查了我好久55555

[root@localhost ~]# cobbler get-loaders

启动 dhcp 服务

[root@localhost ~]# systemctl start dhcpd
顺手挂载一下光盘
[root@localhost ~]# systemctl start dhcpd
[root@localhost ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载

导入镜像文件

[root@localhost /]# cobbler import --path=/mnt/ --name=Centos-7-x86_64 --arch=x86_64
