具体的nginx，php-fpm的配置这里省略，下面只重点说一下mysql的配置
mysql5.7 初始密码获取
启动mysql之后，通过命令 grep 'temporary password' /var/log/mysqld.log 可以拿到root用户的初始密码
修改初始密码
root用户首次登录mysql是需要修改初始密码才能进行后续的操作的,初始密码必须包括数字、大小写字母且长度不能小于8位

set password = password('ryUl1_33au_n0krQ')

创建用户且授权
下面命令会自动创建dbsb用户且授权db_sb库的所有表的权限

以上都是在关闭了系统的防火墙和selinux下操作的
