命令“PassengerAppRoot”无效，可能拼写错误或由服务器配置中未包含的模块定义

我已按照中给出的每一个安装步骤进行操作在 Linux/Unix 生产服务器上安装 Passenger + Apache 适用于 Node.js 应用程序 + Red Hat 6 / CentOS 6（带 RPM） https://www.phusionpassenger.com/library/walkthroughs/deploy/nodejs/ownserver/apache/oss/el6/install_passenger.html一切正常，但是当我尝试使用 WHM 在 centos 6 服务器上的虚拟主机中配置子域来托管我的 botkit 机器人时，出现此错误：

“/usr/local/apache/bin/httpd”命令（进程 27088）报告 结束时出现错误编号 1。第 9 行检测到配置问题 文件/usr/local/apache/conf/includes/post_virtualhost_2.conf.tmp： 无效命令“PassengerAppRoot”，可能拼写错误或由 模块不包含在服务器配置中--- /usr/local/apache/conf/includes/post_virtualhost_2.conf.tmp --- 3 服务器别名 subdomain.mydomain.com 4 ServerAdmin[电子邮件受保护] /cdn-cgi/l/email-protection5 6 7 # 告诉 Apache 和 Passenger 你的位置 应用程序的代码目录是 8 DocumentRoot /var/www/MyApp/Code/public 9 ===> PassengerAppRoot /var/www/MyApp/Code

这是我的配置：

<VirtualHost *:80>
    ServerName www.subdomain.mydomain.com
    ServerAlias subdomain.mydomain.com
    ServerAdmin [email protected] /cdn-cgi/l/email-protection


    # Tell Apache and Passenger where your app's code directory is
    DocumentRoot /var/www/MyApp/code/public
    PassengerAppRoot /var/www/MyApp/code
    #Error logging
     ErrorLog logs/votebot-error_log
     CustomLog logs/votebot-access_log common

    # Tell Passenger that your app is a Node.js app
    PassengerAppType node
    PassengerStartupFile bot.js

    # Relax Apache security settings
    <Directory /var/www/MyApp/code/public>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache >= 2.4:
      #Require all granted
    </Directory>
</VirtualHost>

我尝试删除配置并通过 .htaccess 传递：

PassengerEnabled on
PassengerAppRoot /var/www/MyApp/code
SetEnv NODE_ENV production
SetEnv NODE_PATH /usr/lib/node_modules
PassengerAppType node
PassengerStartupFile bot.js

但它仍然不起作用。 我最近检查并在验证乘客时收到以下消息：

 * Checking whether this Passenger install is in PATH... ✓
 * Checking whether there are no other Passenger installations... (!)

   You are currently validating against Phusion Passenger 5.1.8, located in:

     /usr/bin/passenger

   Besides this Passenger installation, the following other
   Passenger installations have also been detected:

     /usr/local/rvm/gems/ruby-2.4.1/bin/passenger

   Please uninstall these other Passenger installations to avoid
   confusion or conflicts.

问题是我不知道卸载 /usr/local/rvm/gems/ruby-2.4.1/bin/passenger 的步骤是什么。

该错误意味着乘客模块尚未加载LoadModule passenger_module /path/to/.../passenger/buildout/apache2/mod_passenger.so在指定 Passenger 配置选项之前，在 apache 配置中添加一行。

If sudo /usr/bin/passenger-config validate-install通过了 apache 配置测试，那么您有多个 apache 配置，并且在收到错误消息时加载了错误的配置。

根据您的错误，conf 位于/usr/local/apache/conf/，寻找任何LoadModule配置中的行fgrep -RH LoadModule /usr/local/apache/conf/并添加一行来加载 Passenger 模块。
