php - 无法从 php 连接到远程 Mysql 服务器

Question

• 客户端系统:CentOS Linux release 7.0.1406 (Core)
• 客户端 IP:222.222.222.222

• http://test.com查看 ip 222.222.222.222

• 服务器系统:Gentoo Base System release 1.12.13

• 服务器地址:111.111.111.111

连接脚本:

$connection = new \mysqli('111.111.111.111', 'user', 'password', 'db');
if (mysqli_connect_error()) {
    echo "Error: {$connection->connect_error}"; 
}
else {
    echo "Server Info: {$connection->server_info}";
}

当我尝试在浏览器“http://test.com/test.php”中打开时，我得到:

Error: Can't connect to MySQL server on '111.111.111.111' (13)

...但是当我从服务器 222.222.222.222 上的命令行启动此脚本时，我得到了另一个结果:

/usr/bin/php /var/www/reporter/test.php
Server Info: 5.5.14-enterprise-commercial-advanced-log

直接从命令行连接也是正确的:

mysql -h 111.111.111.111 -u user -p -P 3306
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MySQL connection id is 25236357
Server version: 5.5.14-enterprise-commercial-advanced-log MySQL Enterprise Server - Advanced Edition (Commercial)
