使用 nginx 反向代理到 tornado 服务的 8888 端口

http://python.zxb8.cc/index

 

在 nginx.conf 配置文件里添加

 

 

upstream tornados{
server 127.0.0.1:8888;
}

 

vim /usr/local/nginx/conf/nginx.conf

 
#user  nobody;
worker_processes  1;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
 
#pid        logs/nginx.pid;
 
 
events {
    worker_connections  1024;
}
 
 
http {
    include       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  logs/access.log  main;
 
    sendfile        on;
    #tcp_nopush     on;
 
    #keepalive_timeout  0;
    keepalive_timeout  65;
#反向代理设置
    upstream tornados{
         server 127.0.0.1:8888;
     }
 
    #gzip  on;
 
     include conf.d/*.conf;
 
}
 
 
server {
listen 80;
server_name python.zxb8.cc;

# 静态文件直接由 Nginx 处理
location /static/{
alias /www/img/;
expires 24h;
}

location /{
proxy_pass_header Server;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
# 把请求方向代理传给 tornado 服务器，负载均衡
proxy_pass http://tornados;
}
