Shell脚本 一键部署 —LNMP 架构（Nginx Mysql PHP Discuz！论坛）

虚拟机配置信息

使用前请检查yum仓库是否建立，能正常时候yum install安装软件即可，在编写脚本时，分模块进行编写并测试！

Shell脚本一键部署yum仓库

[root@localhost ~]# vim yum.bash
[root@localhost ~]# chmod +x yum.bash 
## 脚本编写完成，在给权限

#!/bin/bash
#function:CentOS7配置本地yum仓库
if [ $USER != root ];then
echo "当前不是root用户，请切换至root用户再次运行脚本"
exit
fi
df -h | grep "/dev/sr0" &> /dev/null
if [ $? != 0 ];then 
  echo "请先到虚拟机挂载光盘，再运行脚本"
  exit
fi
echo "开始备份源yum文件"

echo "执行完成，请查看yum文件数量" && yum repolist | grep repolist
