Nginx 多站点配置实例详解

Nginx 多站点配置实例详解

在一台 VPS 上，我们有时候需要同时跑几个 virtualenv。比如 virtualenv app1 跑的是 Django 的一个应用，而 virtualenv app2 跑的是 Tornado。那么如何配置 Nginx，让它同时支持这两个 virtualenv 的运行呢？

首先是 Nginx 的主配置，位于 etc/nginx/ngnix.conf，让它保持默认就行：

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;

  server {
    listen    80;
    server_name 112.124.7.216;
    #server_name localhost;
    #if ($host != 'www.nowamagic.net' ) { 
    #  rewrite ^/(.*)$ http://www.nowamagic.net/$1 permanent; 
    #} 

    access_log /home/nowamagic/logs/access.log;
    error_log /home/nowamagic/logs/error.log;

    #root     /root/nowamagic_venv/nowamagic_pj;
    location / {
      uwsgi_pass 127.0.0.1:8077;
      #include uwsgi_params;
      include /etc/nginx/uwsgi_params;
      #uwsgi_pass 127.0.0.1:8077;
      #uwsgi_param UWSGI_SCRIPT index;
      #uwsgi_param UWSGI_PYHOME $document_root;
      #uwsgi_param UWSGI_CHDIR $document_root;
    }

    location ~ \.php$ { 
      #root     html; 
      root      /var/www/html;
      fastcgi_pass  127.0.0.1:9000; 
      fastcgi_index index.php; 
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
      include    fastcgi_params; 
    }

    access_log off;
  }


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

注意到这一句，include /etc/nginx/conf.d/*.conf; 它会加载 conf.d 文件夹下的所有配置文件。那么接下来的事情就简单了，我们设计两个 .conf ，一个是 django 的配置，一个是 tornado 的配置。

1. app1_django.conf

server {
  listen    80;
  server_name 112.124.7.216;
  #server_name localhost;
  #if ($host != 'www.imofa.net' ) { 
  #  rewrite ^/(.*)$ http://www.imofa.net/$1 permanent; 
  #} 

  access_log /home/nowamagic/logs/access.log;
  error_log /home/nowamagic/logs/error.log;

  #root     /root/nowamagic_venv/nowamagic_pj;
  location / {
    uwsgi_pass 127.0.0.1:8077;
    #include uwsgi_params;
    include /etc/nginx/uwsgi_params;
    #uwsgi_pass 127.0.0.1:8077;
    #uwsgi_param UWSGI_SCRIPT index;
    #uwsgi_param UWSGI_PYHOME $document_root;
    #uwsgi_param UWSGI_CHDIR $document_root;
  }

  location ~ \.php$ { 
    #root     html; 
    root      /var/www/html;
    fastcgi_pass  127.0.0.1:9000; 
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
    include    fastcgi_params; 
  }

  access_log off;
}

下面是 tornado 的配置：

2. app2_tornado.conf

upstream tornado {
  server 127.0.0.1:8888;
}
 
server {
  listen  80;
  root /root/nmapp2_venv;
  index index.py index.html;
 
  server_name server;
 
  location / {
    #if (!-e $request_filename) {
    #  rewrite ^/(.*)$ /index.py/$1 last;
    #}
  }
 
  location ~ /index\.py {
    proxy_pass_header Server;
    proxy_set_header Host $http_host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Scheme $scheme;
    proxy_pass http://tornado;
  }
}

重启 Nginx：

service nginx restart

OK，两个虚拟环境的 app 都能访问了。
