cobbler-2.8.5
一、关闭防火墙、SELINUX
systemctl disable firewalld //禁止防火墙服务启动
systemctl stop firewalld //关闭防火墙服务
vi /etc/sysconfig/selinux //更改为“SELINUX=disabled”
# getenforce 0//临时关闭SELINUX
# setenforce 0//临时关闭SELINUX
二、更新源
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
yum clean all && yum makecache
四、安装ntp客户端、同步阿里云时间
yum install -y ntp
ntpdate ntp1.aliyun.com
hwclock -w
hwclock
五、安装Cobbler所需相关软件
yum install fence-agents -y
yum install cobbler cobbler-web dhcp tftp-server pykickstart httpd xinetd debmirror -y
六、修改相关的配置文件
1、编辑/etc/httpd/conf/httpd.conf的文件，然后启动httpd服务。
vi /etc/httpd/conf/httpd.conf
systemctl start httpd
systemctl enable httpd
2、编辑/etc/xinetd.d/tftp的文件，然后启动xinetd服务。
vi /etc/xinetd.d/tftp
systemctl start xinetd && systemctl enable xinetd
3、编辑/etc/cobbler/settings文件。
vi /etc/cobbler/settings
在一般模式下直接输入所在行的数字，然后按两下g键跳到指定行。照下面提示修改。
需注意的是：next_server和server的冒号后面有一个空格，不加否则后面会出错
Line:242 manage_dhcp: 1 ##开启DHCP可管理状态
Line:258 manage_tftpd: 1 ##开启tftp管理
Line:261 manage_rsync: 1 ##开启rsync管理
Line:272 next_server: 192.168.1.37 ##你自己的ip
Line:292 pxe_just_once: 1 ##PXE安装 只允许一次，防止误操作
Line:358 restart_dns: 1
Line:359 restart_dhcp: 1
Line:384 server: 192.168.1.37
4、编辑/etc/debmirror.conf文件
vi /etc/debmirror.conf //注释两条内容
5、设置密码，并将/etc/cobbler/settings里默认密码替换掉。
openssl passwd -1 -salt '' 'root' //生成密码，这里设置密码为“root”
vi /etc/cobbler/settings
6、编辑/etc/cobbler/dhcp.template文件。
vi /etc/cobbler/dhcp.template
七、启动cobbler服务
systemctl start cobblerd && systemctl enable cobblerd && systemctl start rsyncd && systemctl enable rsyncd
八、下载bootloader所需文件
cobbler get-loaders # 2.8.5 版本,该命令已移除,x86_64架构安装 yum install syslinux
九、检查服务 查看缺失
cobbler check
防火墙关闭了，/etc/sysconfig/selinux配置文件也修改了，那么这个问题可以忽略掉不管。
十、创建文件夹存放镜像
上传镜像并挂载
mount -o loop /media/iso/CentOS-7-x86_64-DVD-1908.iso /media/cdrom/
cobbler import --name=centos7 --arch=x86_64 --path=/media/cdrom
# 导入镜像此命令耗时会很长，需要静静等待……
# --path 镜像路径
# --name 为安装源定义一个名字
# --arch 指定安装源是32位、64位、ia64, 目前支持的选项有: x86│x86_64│ia64
编辑ks文件
cobbler profile edit --name=centos7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/centos7.ks --kopts='net.ifnames=0 biosdevname=0'
十一、执行同步、启动dhcp服务
systemctl restart rsyncd && systemctl restart xinetd && systemctl restart cobblerd && systemctl enable httpd && systemctl restart dhcpd //重启所有服务
cobbler sync //执行同步
systemctl start dhcpd //启动dhcp
十二、界面化展示
1、新建一台全新的虚拟机，选择好自己的虚拟网卡且不要选择镜像，然后开启虚拟机。
在这里插入图片描述
2、在出现的界面中选择镜像，静静等待加载即可。
十二、定制启动界面
cat /var/lib/tftpboot/pxelinux.cfg/default
修改PXE默认启动选项
默认情况下PXE启动的是Local（启动后会出现local和自定义CentOS7.5-x86_64两个选项，需手动，要无人工干涉，就需要修改）
修改前
修改后
默认时间可修改
不用cobbler sync,否则会恢复原来的配置,编辑ks文件也会覆盖.
十三、参考命令
cobbler profile edit --name=CentOS7-x86_64 --kickstart=/var/lib/cobbler/kickstarts/CentOS7.ks
cobbler profile edit --name=CentOS7-x86_64 --kopts='net.ifnames=0 biosdevname=0'
cobbler sync
systemctl enable rsyncd && systemctl enable xinetd && systemctl enable cobblerd && systemctl enable httpd && systemctl enable dhcpd
systemctl restart rsyncd && systemctl restart xinetd && systemctl restart cobblerd && systemctl enable httpd && systemctl restart dhcpd
