尝试连接到Google Cloud SQL时出现消息"SQLSTATE [HY000] [2002]连接超时"的PDOException [英] PDOException' with message 'SQLSTATE[HY000] [2002] Connection timed out' when trying to connect to google cloud sql

问题描述

Hie成员
所以我试图从外部站点连接到Google Cloud sql

Hie members
so I was trying to connect to Google cloud sql from an external site

我已在Instance->访问控制->授权中授权了Google Cloud中服务器的IP地址

I authorized the ip of the server in google cloud at Instance -> Access Control -> Authorization

并且实例也被分配了IP，比如说"X.X.X.X"， 并且还使用用户名"username"和密码"password"创建了一个用户

and the instance also has been assigned an IP lets say 'X.X.X.X', and a user also has been created with User name 'username' and password 'password'

现在，我用于连接Google Cloud sql的连接代码如下

now the connection code for connecting google cloud sql I used is as follows

$db = new pdo('mysql:host=X.X.X.X;dbname=db','username','password');

，我尝试打开页面，但出现以下错误

and I tried opening the page and I am getting the following error

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2002] Connection timed out' in /home/kannadakavana/public_html/test.php:17 Stack trace: #0 /home/kannadakavana/public_html/test.php(17): PDO->__construct('mysql:host=X....', 'username', '') #1 {main} thrown in /home/kannadakavana/public_html/test.php on line 17

我在做什么错了?

推荐答案

默认情况下，Cloud SQL实例未启用IPv4.

By default Cloud SQL instances does not have IPv4 enable.

您启用了IPv4地址吗?在访问控制> IP地址选项卡下.

Did you enable IPv4 address? It is under Access Control > IP address tab.
