MySQL修改密码、远程连接、创建用户

///修改root密码，localhost只允许本机访问，远程访问则是%，写成IP则只能在制定IP访问。

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');

///创建ca用户、密码123456

CREATE USER 'ca'@'%' IDENTIFIED BY '123456';

///用户权限，创建表、删除表等操作

GRANT ALL ON *.* TO 'cfca'@'%';

///修改root用户可以远程访问

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;

///列出当前用户

SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;

///刷新表，修改后必须操作

flush privileges;
