一、cobbler简介
cobbler是一款自动化操作系统安装的实现，与PXE安装系统的区别是可以同时部署多个版本的系统，而PXE只能选择一种系统。
二、安装cobbler
安装yum源
yum install epel-release -y
yum install dhcp tftp-server xinetd httpd cobbler cobbler-web pykickstart debmirror -y修改配置文件
vim /etc/cobbler/settings
设置server和next_serverIP为服务端IP
生成加密密码，根据配置文件中的提示直接复制命令生成即可
openssl passwd -1 123456
修改tftp配置文件，开启tftp服务
vim /etc/xinetd.d/tftp
配置dhcp服务
vim /etc/dhcp/dhcpd.confsubnet 10.10.10.0 netmask 255.255.255.0 {
option routers 10.10.10.11;
range 10.10.10.100 10.10.10.200;
}
next-server 10.10.10.11;
filename="pxelinux.0";禁用非标准化操作系统
vim /etc/debmirror.conf
安装cman和fence-agents把安装好的操作系统隔离出去
yum isntall cman fence-agents -y启动服务，并加入开机自启动
systemctl start dhcpd
systemctl start httpd
systemctl start cobblerd
systemctl start xinetd
systemctl start rsyncd
systemctl enable httpd cobblerd xinetd rsyncd dhcpd #加入开机自启加载并验证配置文件
cobbler sync #加载配置文件cobbler check #验证配置文件
#由于cobbler取消了get-loaders命令，所以需要手动添加启动文件
cp /usr/share/syslinux/pxelinux.0 /var/lib/cobbler/loaders/
cp /usr/share/syslinux/menu.c32 /var/lib/cobbler/loaders/若执行cobbler check后出现以下提示表示正常
三、导入镜像文件
将镜像文件挂载到本地.虚拟机中挂载一定要提前连接好CD设备，否则会挂载失败。
mount -t iso9660 /dev/cdrom /mnt/
挂载完毕后导入到cobbler
cobbler import --name="centos7.5.1804" --path=/mnt默认的ks配置文件在/var/lib/cobbler/kickstarts，也可以自己生成一份配置文件上传至该目录下即可
#查看上传的镜像
cobbler distro list
#查看ks配置文件
cobbler profile list
#查看配置的镜像信息
cobbler distro report
#上传自定义ks配置文件前，需要将自动生成的文件删除掉
cobbler profile remove --name=centos7.5.1804-x86_64
#添加配置文件
cobbler profile add --name=centos7.5 --distro=centos7.5.1804-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7.cfg四、新建虚拟机测试
通过system-config-kickstart 软件生成的cfg文件需要删掉首行的前两句，否则会报错。
客户机通过网卡启动时会弹出一个可选菜单，选择需要安装的系统即可全自动进行安装
五、cobbler环境部署脚本
此脚本能够自动部署cobbler所需运行环境，并生成两个ks文件分别是最小化安装和图形化安装。可根据自己需要进行导入
由于此脚本实在虚拟机中执行部署，如需用于生产环境请根据需要自行修改。
#!/bin/bash
#获取当前主机IP
IPADD=$(hostname -I|awk '{print $1}')
#提取IP地址前三段
ip_range=$(hostname -I|awk '{print $1}'|head -c 9)
#生成随机密码
passwd=$(openssl passwd -1 123456)
#安装cobbler所依赖的源
yum install epel-release -y
yum install dhcp tftp-server xinetd httpd cobbler cobbler-web pykickstart debmirror -y
sleep 1
yum makecache
sleep 2
#修改settings文件
sed -i "s/^server: 127.0.0.1/server: $IPADD/" /etc/cobbler/settings
