Cobbler简介

网络安装服务器套件 Cobbler(补鞋匠)从前，我们一直在做装机民工这份很有前途的职业。自打若干年前 Red Hat 推出了 Kickstart，此后我们顿觉身价倍增。不再需要刻了光盘一台一台地安装 Linux，只要搞定 PXE、DHCP、TFTP，还有那满屏眼花缭乱不知所云的 Kickstart 脚本，我们就可以像哈里波特一样，轻点魔棒，瞬间安装上百台服务器。这一堆花里胡哨的东西可不是一般人都能整明白的，没有大专以上学历，通不过英语四级，根本别想玩转。总而言之，这是一份多么有前途，多么有技术含量的工作啊。很不幸，Red Hat 最新（Cobbler项目最初在2008年左右发布）发布了网络安装服务器套件 Cobbler(补鞋匠)，它已将 Linux 网络安装的技术门槛，从大专以上文化水平，成功降低到初中以下，连补鞋匠都能学会。对于我们这些在装机领域经营多年，经验丰富，老骥伏枥，志在千里的民工兄弟们来说，不啻为一个晴天霹雳。

实验需要的安装包：

cobbler（linux安装服务器）
cobbler-web（前端界面管理可以通过网页形式进行管理）
dhcp（自动分配IP）
tftp-server （文件传输协议用于放压缩内核和引导文件）
pykickstart（用于阅读和编写kickstart文件）
rsync（数据镜像备份工具，远程同步管理和支持本地复制）
xinetd（网络守护进程服务程序用于管理rsync 和 tftp）
httpd （这里用于检查cobbler文件安装和web管理）

实验过程

虚拟机：centos7系统（网卡选用NET模式选定dhcp 可以实现访问网络）

 # vim /etc/sysconfig/network-scripts/ifcfg-ens33  //编辑网卡
        ONBOOT=yes   (修改成yes)
    # systemctl restart network  //重启网络服务
    # ifconfig //查看网卡信息    
    自动分配的IP 为 192.168.179.129

[root@localhost ~]# yum install cobbler -y

The following are potential configuration items that you may want to fix:

1 : SELinux is enabled. Please review the following wiki page for details on ensuring cobbler works correctly in your SELinux environment:
    https://github.com/cobbler/cobbler/wiki/Selinux
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : 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.

[root@localhost cobbler]# vim /var/log/cobbler/cobbler.log	#日志文件所在位置

[root@localhost cobbler]# mount /dev/cdrom /mnt	      #挂载镜像文件

mount: /dev/sr0 写保护，将以只读方式挂载

[root@localhost cobbler]# cobbler import --path=/mnt/ --name=CentOS-7-x86_64 --arch=x86_64                     #定义路径名字   将镜像文件导入

[root@localhost cobbler]# cobbler list	     #查看列表

[root@localhost cobbler]# systemctl restart httpd.service 		#重新启动下服务

添加一台新的虚拟机，使用和服务器一样的网卡
打开客户机，选择安装centos7系统，等待安装完毕

使用cobbler默认的authn_configfile模块认证方式
cobbler web界面的身份认证和授权配置位于文件/etc/cobbler/modules.conf中，cobbler默认这种方式的认证
可以直接使用htdigest命令添加cobbler用户和密码

[root@localhost ~]# htdigest -c /etc/cobbler/users.digest Cobbler cbadmin #创建新用户
Adding password for cbadmin in realm Cobbler.
New password: 
Re-type new password: 
[root@localhost ~]# systemctl restart cobblerd.service 
[root@localhost ~]# systemctl restart httpd.service

cobbler_web进行操作
[root@promote cobbler]# htdigest -c /etc/cobbler/users.digest Cobbler binbin
Adding password for binbin in realm Cobbler.
New password: 
Re-type new password: 
[root@promote cobbler]# systemctl restart cobblerd.service 
[root@promote cobbler]# systemctl restart httpd.service

最后登录网站输入用户名，密码进行登录操作
