CentOS 7 下 MySQL 5.7 的安装与配置 https://www.jianshu.com/p/1dab9a4d0d5f
mysql 安装完成之后，生成的默认密码在
/var/log/mysqld.log 文件中。使用 grep 命令找到日志中的密码。安装: https://blog.frognew.com/2017/05/yum-install-mysql-5.7.html

wget https://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm yum localinstall mysql57-community-release-el7-11.noarch.rpm yum repolist enabled | grep "mysql.*-community.*" yum repolist all | grep mysql yum -y install mysql-community-server |
