Ruby on rails 无法启动Phusion乘客应用程序

我有一些问题，一直在互联网上搜索类似的问题，但我仍然卡住了。问题在于apache2+phusion乘客。我在主持一个树莓派的节目。我已经安装了apache2和虚拟主机文件。但当我测试应用程序时，我得到的应用程序不能从Phusion passenger启动

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

尝试将文件夹的权限更改为777

sudo chmod -r 777 folder_path.

然后再次运行bundle重新启动apache2服务器

确保Apache用户有权访问Phusion passenger。我假设您使用的是Rasbpian，Debian发行版。在本例中，Apache用户可能是www数据。如果您使用的是CentOS、RedHat或Fedora，则默认Apache用户名为Apache。但是，这只是默认设置。某些软件（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。尝试使用以下命令强制apache访问

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