我在VMWare Openstack上运行两个独立的Fedora 26 Cloud Base映像实例，这两个实例都在同一个VPN下 . 默认情况下，此映像上的防火墙已禁用 .
安全组配置如下：http://imgur.com/a/qKp8Y
其中一个是使用phpMyAdmin运行Apache，另一个是运行mariaDB . 我尝试配置phpMyAdmin连接到远程服务器上的mariaDB数据库，但是在尝试登录时我一直收到以下错误：
＃2002 - 权限被拒绝 - 服务器没有响应（或者未正确配置本地服务器的套接字） .
我尝试使用“mysql -u root -h 10.2.152.103 -p”以及端口3306上的telnet来 Build 与本地计算机上的数据库服务器的直接连接，这两种方法都没有问题 . 因此我得出结论，问题应该是phpMyAdmin而不是mariaDB / mySQL .
我一直在寻找堆栈溢出来寻找解决方案，但无济于事 .
以下内容包含在/ etc / phpMyAdmin /中的config.inc.php文件中：

我必须修改数据库服务器安全组并使用正确的远程安全组（Web服务器的安全组）添加以下规则：Image
