我在生产服务器上安装了一个rails应用程序，其中安装了Passenger和Nginx（带有Passenger模块）。但是，当我运行rvmsudo passenger-status时，它显示0个进程正在运行。
作为参考，这里是我的nginx.conf：
#user www-data;
user root;
worker_processes 4;
pid /var/run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}
http {

# server_name_in_redirect off;

#passenger_root /usr;
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;

##
# Virtual Host Configs
##
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
/etc/nginx/sites-enabled/目录包含相关的服务器信息。以下是
ps aux | grep nginx的输出：root 11417 0.0 0.0 42412 1076 ? Ss 13:13 0:00 nginx: master process /opt/nginx/sbin/nginx
nobody 11418 0.0 0.0 42852 1844 ? S 13:13 0:00 nginx: worker process
当我通过我的网络浏览器访问网站时，我会得到一个“欢迎来到nginx！”登录页。
我在这方面完全是新手，所以可能会有一些愚蠢的简单的事情发生，但我只是需要开始这件事。任何帮助都将不胜感激。

最佳答案
这里是Phusion乘客作者。我99%肯定这只是Nginx配置错误。
首先，Phusion Passengerstarts your app at the first request，所以您看到“0进程”是很正常的，除非显式地用passenger_pre_start配置。
这条线索是，当你试图访问你的网站时，你会看到“欢迎来到nginx”。在99%的情况下，这意味着您的虚拟主机配置错误。由于您修改了配置文件，我无法告诉您到底是什么错误，但它表明Nginx没有将您的请求与您希望它与之关联的虚拟主机块关联。如果你发布你的未经修改的配置文件和你正在访问的URL，我可以告诉你更多。否则，我只能告诉您研究Nginx的服务器名匹配是如何工作的。
