谷歌云SQL与PHP

问题描述

我在将数据库云sql与php连接时遇到问题.我尝试了所有可能的连接方式(pdo，mysqli和mysql)他们都没有工作.

I'm having a problem to connect my DB cloud sql with php.I've tried every possible way to connect (pdo, mysqli & mysql)none of them worked.

我为can sql实例放置了一个IPv4，并在允许的网络部分中授权了计算引擎IP.当我尝试使用以下方式从计算引擎进行连接时:

I've put an IPv4 for the could sql instance and authorized the compute engine IP in the allowed networks section.When I'm trying to connect from the compute engine with

mysql --host=cloud_sql_IP --user=my_user --password

它正在工作，我可以看到表格.

it's working and I'm able to see the tables.

在php端，我输入了以下代码:

On the php side I've put this code:

    $db = mysql_connect(<CLOUD_SQL_IPV4>, 'root', '');
    if (!$db){
       die('Connect Error (' . mysql_error());
    }

我得到连接错误(权限被拒绝)"

and I get "Connect Error (Permission denied)"

当我尝试这种方式时:

$conn = mysql_connect(":/cloudsql/<COMPUTE_INSTANCE>:<DB>", "root", "");
if (!$conn) {
    die('Connect Error (' . mysql_error());
}

我得到:连接错误(无此文件或目录)

I'm getting:"Connect Error (No such file or directory"

我还应该做什么?

谢谢！

推荐答案

挖了2天之后，我设法连接了云数据库

Well after diggin into it for 2 days I managed to connect cloud DB

首先运行此文件以获取权限修复(centos)

first run this for the permission fix (centos)

setsebool httpd_can_network_connect=1

对于php，应该这样写:

And for the php it should be written this way:

new mysqli(
    <IP_V4>, // host
    'root', // username
    '',     // password
    <DB_NAME>, // database name
    null,
    '/cloudsql/<GCE_INSTANCE>:<DB>'
);
