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。
