远程连接centos7 上的mysql报（ERROR 2003 (HY000): Can't connect to MySQL server on '168.x.x.x' (10060) ）...

　　1.MySQL端口 　　因为上一篇文章我就已经给MySQL新建了一新用户，且赋予了远程连接数据库的所有权限（GRANT ALL PRIVILEGES ON *.* TO 'newuser' @ '%' IDENTIFIED BY 'newpass' WITH GRANT OPTION;） 　　且错误是 Cant't connect to MySQL.... 而不是1130 - Host'xxx
