Question

我设法设置了我的nginx.conf文件，它看起来像这样：

root       www www;


worker_processes 1;

worker_rlimit_nofile 8192;

events {

  worker_connections  8000;

  accept_mutex off;

}

error_log  logs/error.log;
pid        logs/nginx.pid;

http {
  # Set the mime-types
  include       mime.types;

  # And the fallback mime-type
  default_type  application/octet-stream;

  # Format for our log files
  log_format   main '$remote_addr - $remote_user [$time_local]  $status '
    '"$request" $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';

  # Click tracking!
  access_log   logs/access.log  main;

  # ~2 seconds is often enough for HTML/CSS, but connections in
  # Nginx are cheap, so generally it's safe to increase it
  keepalive_timeout  5;

  # You usually want to serve static files with Nginx
  sendfile on;

  tcp_nopush on; # off may be better for Comet/long-poll stuff
  tcp_nodelay off; # on may be better for Comet/long-poll stuff

  # Enable Gzip
  gzip  on;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_min_length 1100;
  gzip_buffers     4 8k;
  gzip_proxied any;
  gzip_types text/html text/plain text/xml application/xml application/xml+rss text/css text/javascript application/javascript application/json;

  gzip_static on;

  gzip_proxied        expired no-cache no-store private auth;
  gzip_disable        "MSIE [1-6]\.";
  gzip_vary           on;

  server {
    # listen 80 default deferred; # for Linux
    # listen 80 default accept_filter=httpready; # for FreeBSD
    listen 80 default;

    # e.g. "localhost" to accept all connections, or "www.example.com"
    # to handle the requests for "example.com" (and www.example.com)
    server_name _;

    # Path for static files
    root /srv/www/example.com/public_html/src/static;

    expires 1M;

    # Static assets
    location ~* ^.+\.(manifest)$ {
      expires -1D;
      root   /srv/www/example.com/public_html/src/;
      access_log /srv/www/example.com/logs/static.logs;
    }

    location ~* ^.+\.(ico|ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ {
      # Only set expires max IFF the file is a static file and exists
      if (-f $request_filename) {
        expires max;
        root   /srv/www/example.come/public_html/src/static;
        access_log /srv/www/example.com/logs/static.logs;
      }
    }
  }
}

我对nginx文件的疑问是： 1）我想用域名托管我的应用程序：www.example.com，我改变了nginx.conf文件的哪一行？

我的nginx.conf文件位于与app.py相同的文件夹中。

2）当我尝试通过键入/etc/init.d/nginx start启动nginx时，收到以下错误消息：

错误讯息：

Starting nginx: [emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: bind() to 0.0.0.0:80 failed (98: Address already in use)
[emerg]: still could not bind()
nginx.

我没有对在/ etc / nginx中找到的nginx.conf文件进行任何配置我对这部分的问题是： 3）我如何修复错误？ 4）如何自动启动nginx？

我尝试通过输入来运行我的Tornado应用程序 python app.py 我导航到http://xxx.xx.xxx.xxx:8888，我的应用程序正常运行。

但是，如果我关闭终端（终止程序），我的龙卷风应用程序将不再有效。

我的问题是： 5）我如何自动启动龙卷风应用程序？ 6）我如何在域名上运行龙卷风？

感谢大家的耐心等待。

最诚挚的问候。

Answer 1

1）更改server_name。

2）您可能正在运行Apache。

3）停止服务（使用service httpd stop之类的东西），然后启动nginx。

4）尝试以下命令：

$ chkconfig httpd off
$ chkconfig --add nginx
$ chkconfig nginx on
$ service nginx start

5）看看使用supervisor来运行python应用程序

6）查看nginx wiki有关reverse proxying的信息; nginx处理对域的请求，并将这些请求传递给龙卷风后端。

Answer 2

关于错误信息：使用Ubuntu 11.10时同样的问题，似乎Opera占用了端口80，所以只需修改该值。

使用域名自动在Ubuntu 10.04上使用Nginx启动Tornado
