Nginx不启动Passenger / Nodejs

我无法让Passenger在重新启动nginx时启动我的Nodejs（iojs）应用程序。 我已经按照教程安装了先决条件：

$ nginx -V
nginx版本：nginx / 1.8.0
configuration参数：–with-cc-opt =' – g -O2 -fstack-protector -param = ssp-buffer-size = 4 -Wformat ……… –add-module = / tmp / buildd / nginx-1.8 0.0 /的Debian /模块/乘客/ EXT / nginx的

在http块启用：

  passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini; passenger_ruby /usr/bin/passenger_free_ruby; passenger_nodejs /usr/local/bin/node; passenger_default_user staging; passenger_default_group www-data; 

然后在服务器块中：

• 匹配…用nginx重写规则中的字符
• 在每个后端使用单独的后端和多个域进行清漆
• 在侦听端口443的nginx服务器块上禁用SSL
• Nginx服务器FTP权限被拒绝
• nginx代理服务器上的CORS：跨域请求被阻止：同源策略不允许读取远程资源

 upstream instance { # point to node instance server 127.0.0.1:9000; } # for websockets map $http_upgrade $connection_upgrade { default upgrade; '' close; } server { listen 3000; server_name localhost; set $app_root /home/staging/public_html; root $app_root/tmp; passenger_enabled on; # point to where the app.js file is passenger_app_root $app_root; passenger_sticky_sessions on; location / { proxy_pass http://instance; proxy_http_version 1.1; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; proxy_set_header X-Forwarded-Proto $scheme; } # all static non-scripts are here location /public/ { alias $app_root/app/assets/; } } 

然后重新启动nginx我尝试加载页面＆在我看到的错误日志中：

 … Starting Passenger watchdog... … Starting Passenger core... … Passenger core running in multi-application mode. … Passenger core online, PID 26585 … Starting Passenger UstRouter... … Passenger UstRouter online, PID 26590 … [error] 26736#0: *3 connect() failed (111: Connection refused) while connecting to upstream, client: 188.102.152.94, server: localhost, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:9000/", host: "staging.chatterplot.com:3000" 

去url给我一个502坏的网关。

我还没有看到任何类似的nginx服务器块的例子，所以我觉得我正在做一些非常错误的事情。

 map $http_upgrade $connection_upgrade { default upgrade; '' close; } server { listen 3000; server_name localhost; set $app_root /home/user/public_html/dist; root $app_root/public; passenger_enabled on; passenger_sticky_sessions on; passenger_app_type node; passenger_app_root /home/user/public_html/dist; passenger_app_env production; }
