1、在/etc/mysql/my.cnf中的[mysqld]段注释掉bind-address = 127.0.0.1   2、用mysql -uroot -p 登陆mysql，然后采用以下方法开启远程访问权限：   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;
