手动增加可以远程访问数据库的用户。

  方法一、本地登入mysql,更改 “mysql” 数据库里的 “user” 表里的 “host” 项,将”localhost”改为”%”

mysql -u root -proot
  mysql>use mysql;
  mysql>update user set host = '%' where user = 'root';
  mysql>flush privileges;
  mysql>select host, user from user;

方法二、直接授权(推荐)

  从任何主机上使用root用户,密码:youpassword(你的root密码)连接到mysql服务器:

mysql -u root -proot
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'youpassword' WITH GRANT OPTION;
mysql>flush privileges;
