yum-config-manager --disable mysql55-community
yum-config-manager --disable mysql56-community
yum-config-manager --enable mysql57-community-dmr
yum repolist enabled | grep mysql
Step4:安装mysql 服务器命令：
yum install mysql-community-server
Step5:启动MySQL服务

Step6:查看root 临时密码
grep 'temporary password' /var/log/mysqld.log
Step7:修改root密码
mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456aA?';
Step8:设置远程用户
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456aA?' WITH GRANT OPTION;
