Phusion Passenger 应用程序无法启动

Question

我遇到了一些问题，并且一直在互联网上搜索类似的问题，但我仍然卡住了。问题是关于 apache2 + phusion passenger。我在 raspberry pi 上托管。我已经设置了 apache2 和虚拟主机文件。但是当我测试应用程序时，我得到应用程序无法从 Phusion passenger 启动。

当我连接到外部 PC 上的本地主机时，Phusion Passenger 出错。日志文件：

这是我的 /apache2/sites-available 虚拟主机配置：

<VirtualHost *:80>
    ServerName 127.0.0.1
    DocumentRoot /var/www/testPage/public
    RailsEnv development
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    <Directory "/var/www/testPage/public">
        Options FollowSymLinks
    AllowOverride all
    </Directory>
</VirtualHost>

我还通过使用 a2ensite 将其切换为默认使用此配置。

Answer 1

尝试将文件夹的权限更改为 777

sudo chmod -r 777 folder_path.

然后运行再次捆绑重新启动apache2服务器

Answer 2

确保 Apache 用户可以访问 Phusion passenger。我假设您使用的是 Debian 发行版 Rasbpian。在这种情况下，Apache 用户可能是 www-data。如果您使用的是 CentOS、RedHat 或 Fedora，则默认的 Apache 用户名是 apache。然而，这只是默认设置。某些软件（例如 cPanel）可能会更改默认的 apache 用户。对于 cPanel，默认的 apache 用户称为 nobody。尝试以下命令强制执行 apache 访问。

sudo chown -R www-data:www-data /phusion/passenger/installation/path
