修改MySQL的root用户的密码以及打开远程连接

[root@localhost mysql]# mysql -u root mysql

mysql> use mysql;  

mysql> desc user;  

mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "root"; //为root添加远程连接的能力 

mysql> update user set Password = password('123456') where User='root'; //设置root用户密码 

mysql> select Host,User,Password from user where User='root';  

mysql> flush privileges;  mysql> exit

重新登录
