简介Cobbler 可以用来快速建立 Linux 网络安装环境，不再需要使用光盘一台一台地安装 Linux，只要配置好PXE、DHCP、TFTP和 Kickstart 脚本，即可瞬间完成安装上百台服务器的任务
Cobbler特点：
1)Cobbler支持多种Linux操作系统得快速部署，对DHCP、HTTP、TFTP、Kiskstart、YUM仓库、电源等进行统一管理
2)Cobbler提供实现不同用户需求得可定制系统部署方案
3)Cobbler分别提供命令管理和Web界面管理、方便Cobbler管理员使用
准备一台Centos7虚拟机，配置IP地址和hostname，关闭防火墙和selinux，同步系统时间
安装epel源
[root@localhost ~]# yum install epel-release -y安装相关软件包
[root@localhost ~]# yum install -y cobbler cobbler-web tftp* rsync xinetd http* syslinux dhcp* pykickstart
#启动服务
[root@localhost ~]# systemctl start cobblerdCobbler检查
#根据检查结果进行修改
[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 : 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
4 : change ‘disable‘ to ‘no‘ in /etc/xinetd.d/tftp
5 : 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 have installed 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.
6 : enable and start rsyncd.service with systemctl
7 : debmirror package is not installed, it will be required to manage debian deployments and repositories
8 : 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
9 : fencing tools were not found, and are required to use the (optional) power management features. install cman or fence-agents to use them处理错误1、2、8
#生成随机密码串
[root@localhost ~]# openssl passwd -1 -salt ‘abcefghljkl‘ ‘123456789‘
#123456789为机器登陆密码
#abcefghljkl为随意编写的字节干扰码
#修改配置文件
[root@localhost ~]# vi /etc/cobbler/settings
#改为本机ip
server: local_ip
next_server: local_ip
#设置新建机器的登陆密码串
default_password_crypted: "$1$abcefghl$Gibcsp93juzDkZImG.xAk0"处理错误3
