一键cobbler批量安装脚本

时间：2022-10-05 17:03:54

前几天机房上架180台服务器，太多了，使用了cobbler批量安装，具体的看我上代码，我把配置cobbler的命令给堆积起来，也算是个脚本吧，欢迎拍砖指正，下面我上脚本：

 #!/bin/bash

 # 关闭selinux

  setenforce

 # 关闭firewalld防火墙

  systemctl stop firewalld

 # 下载阿里云镜像源

  wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

 # 安装cobbler

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

 # 启动httpd、cobblerd

  systemctl start httpd

  systemctl start cobblerd

 # 检查cobbler配置存在的问题,逐一解决

  cobbler check

 # 修改/etc/cobbler/settings文件中的server参数的值为提供cobbler服务的主机相应的IP地址或主机名，如server: 192.168.222.129

 # 备份原文件

  cp /etc/cobbler/settings{,.ori}

  sed -i 's/server: 127.0.0.1/server: 192.168.222.129/' /etc/cobbler/settings

 # 修改/etc/cobbler/settings文件中的next_server参数的值为提供PXE服务的主机相应的IP地址，如next_server: 192.168.222.129

  sed -i 's/next_server: 127.0.0.1/next_server: 192.168.222.129/' /etc/cobbler/settings

 # 修改/etc/xinetd.d/tftp文件中的disable参数修改为 disable = no

 # 备份源文件

  cp /etc/xinetd.d/tftp{,.ori}

  sed -i 's/disable.*= yes/disable                 = no/g' /etc/xinetd.d/tftp

 # 执行 cobbler get-loaders 命令即可；否则，需要安装syslinux程序包，而后复制/usr/share/syslinux/{pxelinux.,memu.c32}等文件至/var/lib/cobbler/loaders/目录中

  cobbler get-loaders

 # 修改rsync配置文件

  sed -i s/"disable.*= yes"/"disable         = no"/g /etc/xinetd.d/rsync

 # 开启rsync的服务开机自启动

  systemctl enable rsyncd

 # 开启rsync的服务

  systemctl start rsyncd

 # 生成密码来取代默认的密码，更安全

  openssl passwd - -salt 'renjunjie' ''

  sed -i s/'default_password_crypted:.*'/'default_password_crypted: "$1$renjunji$G7LpR5255qFguHrw7E0KP\/"'/g /etc/cobbler/settings

 # 安装cman fence-agents

  yum install -y cman fence-agents

 # 其他一些没有提示报错的小修改

  sed -i 's/manage_dhcp: 0/manage_dhcp: 1/g' /etc/cobbler/settings

  sed -i 's/pxe_just_once: 0/pxe_just_once: 1/' /etc/cobbler/settings

  systemctl restart cobblerd.service

  cobbler check

 # 配置dhcp

  cat > /etc/dhcp/dhcpd.conf <<EOF

 subnet 192.168.222.0 netmask 255.255.255.0 {

  cd /var/www/cobbler/ks_mirror/
