本文介绍了通过PHP从SSL连接到远程MySQL服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正尝试使用mysql_connect从PHP通过SSL连接到远程MySQL服务器:

I'm trying to connect to remote MySQL server with SSL from PHP using mysql_connect:

$link = mysql_connect(
    "ip",
    "user",
    "pass",
    true,
    MYSQL_CLIENT_SSL
)

有史以来最严重的错误:

And get worst error ever:

SSL connection error

我在my.cnf中添加了以下参数:

I've added following params into my.cnf:

[client]
ssl-ca      =/etc/mysql/ssl/ca-cert.pm
ssl-cert    =/etc/mysql/ssl/client-cert.pem
ssl-key     =/etc/mysql/ssl/client-key.pem

所以我可以使用

#mysql -h ip -u user -p

所以到mysql服务器的连接可以正常工作，据我了解，问题出在php/mysql合作中.可能我缺少一些参数.

So connection to mysql server do work and as far as I understand problem is in php/mysql cooperation. Probably I'm missing some params.

不幸的是，我不能使用mysqli lib，因为pdo_mysql的适配器太多.

Unfortunately I can't use mysqli lib because have too many working adapters for pdo_mysql.

我的PHP版本是5.3.6-13ubuntu3.6MySQL版本是5.1.61

My PHP Version is 5.3.6-13ubuntu3.6MySQL version is 5.1.61

我还添加了

mssql.secure_connection = On

到我的php.ini

to my php.ini

我们将不胜感激！

推荐答案

您正在使用旧的MySQL扩展("mysql_connect")，该扩展已不再开发(仅维护).由于您使用的是PHP 5，因此您可能想使用 MySQLi ，即MySQLi 改进扩展名.除其他外，它具有面向对象的界面，支持准备/多个语句，并具有增强的调试功能.您可以在此处了解更多有关转换为MySQLi的信息.关于mysqli类本身的更多信息此处.

You're using the old MySQL extension ("mysql_connect"), which is no longer under development (maintenance only). Since you're using PHP 5, you may want to use MySQLi, the MySQL Improved Extension. Among other things, it has an object-oriented interface, support for prepared/multiple statements and has enhanced debugging capabilities. You can read more about converting to MySQLi here; more about the mysqli class itself here.

下面是一些示例代码，可以帮助您入门:

Here is some sample code that may help you get started:

<?php
ini_set ('error_reporting', E_ALL);
ini_set ('display_errors', '1');
error_reporting (E_ALL|E_STRICT);

$db = mysqli_init();
mysqli_options ($db, MYSQLI_OPT_SSL_VERIFY_SERVER_CERT, true);

$db->ssl_set('/etc/mysql/ssl/client-key.pem', '/etc/mysql/ssl/client-cert.pem', '/etc/mysql/ssl/ca-cert.pem', NULL, NULL);
$link = mysqli_real_connect ($db, 'ip', 'user', 'pass', 'db', 3306, NULL, MYSQLI_CLIENT_SSL);
if (!$link)
{
    die ('Connect error (' . mysqli_connect_errno() . '): ' . mysqli_connect_error() . "\n");
} else {
    $res = $db->query('SHOW TABLES;');
    print_r ($res);
    $db->close();
}
?>

如果 PDO_MYSQL 确实是您想要的，那么您需要做这样的事情:

If PDO_MYSQL is really what you want, then you need to do something like this:

<?php
$pdo = new PDO('mysql:host=ip;dbname=db', 'user', 'pass', array(
    PDO::MYSQL_ATTR_SSL_KEY    =>'/etc/mysql/ssl/client-key.pem',
    PDO::MYSQL_ATTR_SSL_CERT=>'/etc/mysql/ssl/client-cert.pem',
    PDO::MYSQL_ATTR_SSL_CA    =>'/etc/mysql/ssl/ca-cert.pem'
    )
);
$statement = $pdo->query("SHOW TABLES;");
$row = $statement->fetch(PDO::FETCH_ASSOC);
echo htmlentities($row['_message']);
?>

但是，只有最新版本的PHP具有对PDO的SSL支持，并且(至少)在版本5.3.8中默认忽略了SSL选项:请参见错误报告.

However, only recent versions of PHP have SSL support for PDO, and SSL options are silently ignored in (at least) version 5.3.8: see the bug report.

祝你好运！
