【亲测可用】Cobbler自动批量部署Linux系统

标签：Cobbler web   Cobbler   自动装机   批量装机   linux批量安装   

Cobbler支持命令行管理，web界面管理，还提供了API接口，可以方便二次开发使用。

Cobbler客户端Koan支持虚拟机安装和操作系统重新安装，使重装系统更便捷。

环境准备

1. VMware 12 虚拟机
2. Centos 7 操作系统（网卡模式：NAT模式；IP地址为：192.168.96.129）
3. 软件包： epel-release-latest-7.noarch.rpm 密 码：fqw7

服务部署

1. 安装 epel-release-latest-7.noarch.rpm 软件包（cobbler相关软件包是由EPEL源提供的）

   rpm -ivh /mnt/epel-release-latest-7.noarch.rpm

2. 安装cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd软件包

yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd rsync xinetd -y

3. 修改cobbler主配置文件:

   vim /etc/cobbler/settings

next-server：192.168.96.129 #tftp服务器的ip地址
server：192.168.96.129 #服务器的ip地址
manage_dhcp:1 #开启dhcp功能

4. 使用cobbler check对cobbler做检查设置

   cobbler check 

---------------------提示内容：需要优化-----------------------------------
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 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp

3 : Some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run ‘cobbler get-loaders‘ to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you haveinstalled a recent version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The ‘cobbler get-loaders‘ command is the easiest way to resolve these requirements.

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

7 : 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.

5. 修改cobbler用户的初始密码，可以使用以下命令生成密码

   openssl passwd -1 -salt ‘abc123‘ ‘abc123‘    #盐值加密

$1$abc123$9v8z2./E/PZihXrVcy3II0 #加密后的密码

将此密码替换到settings文件中

default_password_crypted: "$1$abner$kDle2KnwbPHdm1UZEE79V." #替换密码，此为root用户密码
:wq! #保存退出

6. 下载引导操作系统文件

   cobbler get-loaders 

7. 启动rsyncd服务

   systemctl start rsyncd.service

8. 开启tftp服务

   vim /etc/xinetd.d/tftp

   disable = no #将yes修改为no，启用tftp

重启xinetd服务

systemctl restart xinetd.service

9. 编辑dhcp模板文件

   vim /etc/cobbler/dhcp.template       

   #cobbler控制的dhcp服务模板

subnet 192.168.96.0 netmask 255.255.255.0 {
option routers 192.168.96.1; #修改网关
option domain-name-servers 192.168.96.2; #修改DNS
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.96.100 192.168.96.200; #修改地址池
：wq! #保存退出

10. 同步生成DHCP配置文件

    cobbler sync      

11. 启动dhcpd服务

    systemctl restart dhcpd.service    

12. 加载系统光盘镜像

    mount /dev/sr0 /mnt

    #导入iso镜像

    cobbler import --path=/mnt/ --name=CentOS-7-x86_64 --arch=x86_64 

    #默认导入存放位置

    /var/www/cobbler/ks_mirror/CentOS-7-x86_64        

    

#查看导入结果

cobbler list

htdigest -c /etc/cobbler/users.digest Cobbler maaiqiang
输入两次确认密码（123123）

#重新启动cobblerd、httpd服务

systemctl restart cobblerd.service
