一键搭建LNMP

未避免网络相关问题，此脚本基于离线安装
脚本只对nginx、php-fpm做了基础优化，还请根据自己的需求修改相关配置文件
重新登陆后可以使用nginx,mysql,php-fpm等命令
关于https，nginx配置文件中已经做了全站https的代码，只是被注释了，请根据自己的域名、证书修改以下配置文件：
/apps/nginx/conf/nginx.conf

系统环境要求：

没有安装过nginx、mysql、php软件以及apache、mariadb
没有相关软件生成的文件残留
未创建nginx，mysql用户

建议

脚本跑完后，第一次使用域名访问以完成wordpress安装，域名会被记录到数据库中，以后如果更换域名，只要重新做域名解析即可。若第一次使用IP访问，浏览器地址会显示IP地址而不是域名，更换域名及IP都需要手动对数据库修改，因此不建议使用IP访问安装wordpress。
