Question

尝试在我可以运行nginx的AWS EC2实例上提供金字塔应用程序时遇到一些问题，当我尝试使用AWS提供的URL访问该站点时，我可以看到Nginx的默认网页。但是，当我尝试使用以下命令提供金字塔应用程序时，浏览器仍然显示nginx网页而不是金字塔网页。

登录AWS ssh后，我用于为金字塔应用程序提供服务的命令是：

$ /home/ec2-user/env/bin/uwsgi --ini-paste-logged /home/ec2-user/env/FRuler/production.ini

/etc/nginx/nginx.conf

的设置

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;

    server {
        listen          <my.aws.ip.address>:80;
        server_name     <my.aws.url.address> <my.domain.address>;
        index           index.html index.htm index.py;
        access_log  /var/log/nginx/<my.domain.address>.log;
        error_log   /var/log/nginx/<my.domain.address.log>.error;
        root            /home/ec2-user/;
        charset         utf-8;

        location / {
            uwsgi_pass  127.0.0.1:3003;
            include     uwsgi_params;
        }

        location /static {
            root        /home/ec2-user/env/FRuler/fruler/;
        }
    }

}

/home/ec2-user/env/FRuler/production.ini

的设置

mypaste = /home/ec2-user/env/FRuler/production.ini
paste = config:%(mypaste)
paste-logger = %(mypaste)

当我尝试使用以下方式提供金字塔应用时：

$ /home/ec2-user/env/bin/uwsgi --ini-paste-logged /home/ec2-user/env/FRuler/production.ini

金字塔默认网页未显示，此后没有命令提示符。

然后我还尝试关闭终端窗口，当我尝试通过ssh重新登录AWS并执行以下命令时：

**$ ps ax | grep uwsgi**
31452 ?        S      0:00 /home/ec2-user/env/bin/uwsgi --ini-paste-logged /home/ec2-user/env/FRuler/production.ini

31502 pts/1    S+     0:00 grep --color=auto uwsgi

接下来，我尝试查看/home/ec2-user/env/FRuler/uwsgi.log

我们在专用的Web服务器上尝试了这种完全相同的设置，没有任何问题（显示金字塔默认网页）。但是，当我们在AWS上尝试它时，它不会提供默认的金字塔默认页面。

非常感谢任何建议。
