mysql连接远程服务器详细过程-1405-2003

1，远程防火墙打开 3306端口，否则报2003错误

2，服务器授权  

 先修修改mysql root密码：SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');

代码：

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'password' WITH GRAN
T OPTION;

 FLUSH PRIVILEGES;

　

代码  ：

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('A73A44A933BF3D8DB69CA65AD5A3EE40');
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY 'A73A44A933BF3D8DB69CA65AD5A3EE40' WITH GRANT OPTION;
FLUSH PRIVILEGES;

接下来使用navicat，就可以连接远程数据库了，
