【问题描述】：

我目前正在尝试在托管 VPS 上部署我的 Symfony 4 网站，我确实非常成功地设置了所有内容，安装了 Apache2、php 7.2、mysql 服务器和 phpmyadmin。 然后我开始相应地配置我的服务器以托管一个 Symfony 4 网站，在部署我自己的应用程序之前，我尝试部署一个较小的应用程序，以便我知道至少有一部分可以与无数据库无捆绑应用程序一起使用。 当我尝试访问我的网站时没有任何反应，在 /var/log/apache2 中生成以下错误日志：

我相信这来自于某处循环的网站配置文件，我在网上看到过 .htaccess 和配置文件循环的情况，但在这里我删除了 .htaccess 文件时没有任何地方。 他是我的网站配置：

<VirtualHost *:80>
    ServerName vps562960.ovh.net
    ServerAlias vps562960.ovh.net

    DocumentRoot /var/www/releases/20180710151554/public
    <Directory /var/www/releases/20180710151554>
        AllowOverride None
        Require all granted
        Allow from All

        <IfModule mod_rewrite.c>
            Options -MultiViews
            RewriteEngine On
            RewriteCond %REQUEST_FILENAME !-f
            RewriteRule ^(.*)$ index.php [QSA,L]
        </IfModule>
    </Directory>

    # uncomment the following lines if you install assets as symlinks
    # or run into problems when compiling LESS/Sass/CoffeeScript assets
    # <Directory /var/www/crvfakeexample.com>
    #     Options FollowSymlinks
    # </Directory>

    # optionally disable the RewriteEngine for the asset directories
    # which will allow apache to simply reply with a 404 when files are
    # not found instead of passing the request into the full symfony stack
    <Directory /var/www/releases/20180710151554/public/bundles>
        <IfModule mod_rewrite.c>
            RewriteEngine Off
        </IfModule>
    </Directory>
    ErrorLog /var/log/apache2/vps562960.ovh.net_error.log
    CustomLog /var/log/apache2/vps562960.ovh.net_access.log combined

    # optionally set the value of the environment variables used in the application
    #SetEnv APP_ENV prod
    #SetEnv APP_SECRET <app-secret-id>
    #SetEnv DATABASE_URL "mysql://db_user:db_pass@host:3306/db_name"
</VirtualHost>

我开始对部署该网站失去希望。有没有人遇到过类似的情况，或者你们知道我做错了什么吗？

提前致谢。

【参考方案1】：

问题很可能是 Apache 服务器没有将环境变量设置到 PHP 全局数组 $_SERVER 中。但是 symfony 试图准确地在 $_SERVER 数组中找到环境变量。要么更新 public/index.php 并将所有 $_SERVER 替换为 $_ENV 或取消注释 Apache 网站配置中的 SetEnv 指令。
