一键cobbler批量安装脚本

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
