公司没有专职运维，搭建服务器全部都是程序员操作。以前手动搭建需要1天时间，搭建过程很慢、很无聊，于是自己总结了如下脚本，执行完需要18分钟，以后再也不用苦逼的搭建环境了。

脚本使用到的jdk-8u162-linux-x64.tar.gz、nginx-1.12.2.tar.gz、mysql-community.repo、nginx、backup.sh、start.sh已经上传到 Centos开发环境 ，大家可以下载下来，上传到自己的服务器，做成下载链接。接着将xx.com.cn替换成自己的下载地址， 111111替换成自己的数据库密码，就能运行脚本了。
下载链接用的公司内部的，无法分享，小伙伴有可用的下载链接、遇到问题欢迎留言！
