亲测可用

1 wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

2  rpm -ivh mysql-community-release-el7-5.noarch.rpm

3 sudo yum install mysql-server

4 service mysql restart

5 修改密码

use mysql;

update user set password=password('new password') where user='root';   ---这里我的密码是new password 修改成自己的就行

flush privileges;

远程连接报错处理：

错误代码是1130，ERROR 1130: Host xxx.xxx.xxx.xxx is not allowed to connect to this MySQL server 是无法给远程连接的用户权限问题 

给用户授权 

我用的用户是root 密码new password

首选语法为: 
Sql代码 
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION; 

示例: 
Sql代码 
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'new password' WITH GRANT OPTION; 

执行完后,再 
mysql:flush privileges; 
刷新一下权限就可以了,不用重启
