1、在/etc/mysql/my.cnf中的[mysqld]段注釋掉bind-address = 127.0.0.1

2、用mysql -uroot -p 登陸mysql，然后采用以下方法開啟遠程訪問權限：

方法1：mysql>use mysql;
     mysql>update user set host = '%' where user = 'root';

    mysql>FLUSH RIVILEGES；

方法2：mysql>GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
