sudo vim /etc/mysql/my.cnf

mysql -u root -p
为需要远程登录的用户赋予权限：
代码如下:
mysql>use mysql;
mysql>delete from user where user=‘‘;(删除匿名用户)
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY "123" with grant option;(123为密码)
mysql> flush privileges;
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY "123" with grant option;(123为密码)
mysql> flush privileges;
退出mysql（exit）
然后重启mysql服务（sudo service mysql restart）
远程登录命令：
mysql -h 125.216.231.188 -u root -p（-h后跟的是要登录主机的ip地址）
