一、先檢查MySQL的登錄用戶是否開啟了訪問權(quán)限

mysql> use mysql;
mysql> select host,user from user; 

mysql-root-state

修改root用戶的訪問權(quán)限

mysql> update user set host = '%' where user = 'root';

為root用戶賦予遠(yuǎn)程訪問權(quán)限

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your password' WITH GRANT OPTION;

刷新權(quán)限或重啟MySQL

mysql> flush privileges;

二、檢查MySQL的配置文件是否設(shè)置了端口綁定

root@ubuntu: vim /etc/mysql/my.cnf

將文件中的bind-address = 127.0.0.1 注釋掉，如下：

# bind-address = 127.0.0.1

保存退出重啟MySQL

root@ubuntu: service mysql restart
