我已经在我的本地机器上安装了MySQL Community Edition 5.5，我想允许远程连接，这样我就可以从外部源连接。
我该怎么做呢?

请按照下面提到的步骤来设置MySQL用户的通配符远程访问。
(1) Open cmd. (2) navigate to path C:\Program Files\MySQL\MySQL Server 5.X\bin and run this command. mysql -u root -p (3) Enter the root password. (4) Execute the following command to provide the permission. GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'IP' IDENTIFIED BY 'PASSWORD'; USERNAME: Username you wish to connect to MySQL server. IP: Public IP address from where you wish to allow access to MySQL server. PASSWORD: Password of the username used. IP can be replaced with % to allow user to connect from any IP address. (5) Flush the previleges by following command and exit. FLUSH PRIVILEGES; exit; or \q

对于需要它的人，检查防火墙端口3306是否也打开了，如果您的防火墙服务正在运行。
只是F.Y.I 我为这个问题苦恼了好几个小时。最后，我打电话给我的主机提供商，发现在我使用云服务器的情况下，在1and1的控制面板中，他们有一个二级防火墙，你必须克隆并添加端口3306。一加进去我就直接进去了。

在完成以上所有操作后，我仍然无法以根用户远程登录，但是telnet到3306端口确认MySQL正在接受连接。
我开始查看MySQL中的用户，并注意到有多个具有不同密码的根用户。
select user, host, password from mysql.user;
所以在MySQL中，我再次为root设置了所有密码，我最终可以以root身份远程登录。
use mysql;
update user set password=PASSWORD('NEWPASSWORD') where User='root';
flush privileges;
