远程访问 MySQL
1：将 localhost 改成 “%”
修改 “mysql” 数据库里的 “user” 表里的 “host” 项，将”localhost”改成”%”
mysql>use mysql;
mysql>update user set host = ‘%’ where user = ‘root’;
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;
2：使用 myuser/mypassword 从任何主机连接到 mysql 服务器:
GRANT ALL PRIVILEGES ON . TO ‘myuser’@’%’ IDENTIFIED BY ‘mypassword’ WITH GRANT OPTION;
使用myuser/mypassword从ip为192.168.225.166的主机连接到mysql服务器:
GRANT ALL PRIVILEGES ON . TO ‘myuser’@’192.168.225.166’ IDENTIFIED BY ‘mypassword’ WITH GRANT OPTION;
3：泛授权
mysql -h localhost -u root
mysql>GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ WITH GRANT OPTION; //赋予任何主机上以root身份访问数据的权限
mysql>FLUSH PRIVILEGES;[17]
