使用 Laravel 通过 SSL 连接 MySQL

Question

我在 Laravel 应用程序中通过 ssl 连接到我的数据库时出现问题。我的配置如下:

       'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
            'sslmode' => 'require',
            'options'   => array(
                PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false,
                PDO::MYSQL_ATTR_SSL_KEY => '/certs/client-key.pem',
                PDO::MYSQL_ATTR_SSL_CERT => '/certs/client-cert.pem',
                PDO::MYSQL_ATTR_SSL_CA => '/certs/ca.pem',
            ),
        ],

DB_CONNECTION=mysql
DB_HOST=xxx.xxx.xxx.xxx
DB_PORT=3306
DB_DATABASE=db_name
DB_USERNAME=db_user
DB_PASSWORD=xxxx

这些设置在 MySQL 服务器上给了我以下错误。

2018-10-30T09:18:25.403712Z 71 [Note] Access denied for user 'user'@'xxx.xxx.xxx.xxx' (using password: YES)

通过 mysql-client 它可以完美地从客户端服务器运行。

mysql -u user -p -h xxx.xxx.xxx.xxx --ssl-ca=/certs/ca.pem --ssl-cert=/certs/client-cert.pem --ssl-key=/certs/client-key.pem

与上述命令连接时在客户端上执行的“\s”命令的输出。

该应用程序在基于 php:7.2.11-fpm 的 docker 容器内运行图片。并配置了以下 php 扩展。
RUN docker-php-ext-install bcmath zip pdo_mysql json tokenizer

OpenSSL 版本:

openssl

OpenSSL support => enabled
OpenSSL Library Version => OpenSSL 1.1.0f  25 May 2017

Openssl default config => /usr/lib/ssl/openssl.cnf

Directive => Local Value => Master Value
openssl.cafile => no value => no value
openssl.capath => no value => no value

对此有何想法？这让我忙了几个小时......

我终于解决了这个问题。上面的配置其实很好。我直接在 docker 容器中工作。由于某种原因，配置保存在缓存中。

以下命令未清除配置缓存:

php artisan config:clear
php artisan config:cache
php artisan cache:clear

当我创建一个新用户来连接数据库以测试某些内容时，我注意到了这一点。我使用新配置重建容器，现在一切正常。
