PHP警告:mysqli_connect():( HY000/2002):连接被拒绝

Question

我使用PHP 5.5和MAMP(从这里下载):

我有一个像这样的基本脚本:

<?php
$servername = "127.0.0.1";
$username = "root";
$password = "root";

// Create connection
$conn = mysqli_connect($servername, $username, $password);

// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>

当我运行此脚本时,我收到此错误:

PHP Warning:  mysqli_connect(): (HY000/2002): Connection refused in /Applications/MAMP/htdocs/test/test.php on line 7

我需要在MAMP或PHP中设置一些配置问题吗？

Answer 1

如果其他人遇到此问题,MAMP上的默认端口是mysql 8889,但是php期望用于mysql的端口是3306.所以你需要打开MAMP,转到首选项,并将MAMP mysql端口更改为3306,然后重启mysql服务器.现在连接应该成功使用host = localhost,user = root,pass = root.

Answer 2

有时你需要在服务器中包含mysql db port id.

$serverName = "127.0.0.1:3307";
