CentOS *** ERROR: Phusion Passenger doesn't seem to be running

Question

当我通过 capistrano 将我的 rails 应用程序部署到我的 CentOS 服务器时，我一直收到此错误：

*** ERROR: Phusion Passenger doesn't seem to be running. If you are sure that it is running, then the causes of this problem could be one of:

You customized the instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument. If so, please set the environment variable PASSENGER_INSTANCE_REGISTRY_DIR to that directory and run this command again.

The instance directory has been removed by an operating system background service. Please set a different instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument.

在我的服务器上，我有 apache 和 passenger 5.0.30 首先，我在堆栈上查看其他答案：。不幸的是，没有什么能帮助我。我也尝试从 apache conf 设置 env 路径和其他设置。知道我应该更改什么以部署我的 rails 应用程序吗？ PATH 中第一个 passenger-status 的完整路径在哪里？它匹配 passenger_root 吗？以下是我的日志：

$ passenger-config validate-install

我的环境路径：

    SUDO_USER=userr
    SUDO_UID=1001
    SUDO_GID=100
    PASSENGER_INSTANCE_REGISTRY_DIR=/tmp

我肯定做错了什么。谢谢你的每一个建议。

Answer 1

我终于解决了我的问题。我做了两件事。

首先，我在主目录中创建了新的临时文件夹。然后在 Apache 配置文件中我添加了

PassengerInstanceRegistryDir /home/userr/instancetemp

然后我用

将它推送到我的环境路径

echo 'PASSENGER_INSTANCE_REGISTRY_DIR=/home/userr/instancetemp' >> ~/.bash_profile

我认为这已经足够了，但我还在我的 capistrano 配置中添加了这条路径

set :default_env, { 
  "PASSENGER_INSTANCE_REGISTRY_DIR" => "/home/userr/instancetemp"
}

Answer 2

问题似乎是 systemd 私有临时功能，您可以为 httpd 禁用它：

mkdir /etc/systemd/system/httpd.service.d
echo "[Service]" >  /etc/systemd/system/httpd.service.d/nopt.conf
echo "PrivateTmp=false" >> /etc/systemd/system/httpd.service.d/nopt.conf
systemctl daemon-reload
systemctl restart httpd

Passenger 5.0 不再使用 /tmp 状态信息，因此即使在私人临时工中也应该开箱即用。
