测试环境:

服务器配置: 4 x Intel(R) Xeon(R) CPU E5405 @ 2.00GHz， 4G内存, 操作系统: CentOS 5.3 x86_64

nginx前端 + 4 tornado(0.2) web process

tornado: http://www. (已被墙)

测试场景:

http get请求，服务器端直接返回"hello world"

代码及nginx配置:

main.py:

#!/usr/bin/python
# -*- coding: utf-8 -*-
"""web main"""

from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop
from tornado.web import RequestHandler, Application, authenticated

#from rockps.auth import AuthHandler

class MainHandler(RequestHandler):
    def get(self):
        self.write("hello world")

settings = {
}

application = Application([
    (r"/", MainHandler),
], **settings)

if __name__ == "__main__":
    http_server = HTTPServer(application)
    http_server.listen(8081)
    IOLoop.instance().start()

nginx.conf:

user root;
worker_processes 1;

error_log /var/nginx_error.log;
pid /var/run/nginx.pid;

events {
    worker_connections 51200;
    use epoll;
}

http {
    # Enumerate all the Tornado servers here
    upstream frontends {
        server 127.0.0.1:8081;
        server 127.0.0.1:8082;
        server 127.0.0.1:8083;
        server 127.0.0.1:8084;
    }

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

    access_log /var/log/nginx/access22.log;

    keepalive_timeout 65;
    proxy_read_timeout 200;
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    gzip on;

               application/x-javascript application/xml
               application/atom+xml text/javascript;

    # Only retry if there was a communication error, not a timeout
    # on the Tornado server (to avoid propagating "queries of death"
    # to all frontends)
    proxy_next_upstream error;

    server {
        listen 8085;

        # Allow file uploads
        client_max_body_size 50M;

        location ^~ /static/ {
            root /var/www;
            if ($query_string) {
                expires max;
            }
        }
        location = /favicon.ico {
            rewrite (.*) /static/favicon.ico;
        }
        location = /robots.txt {
            rewrite (.*) /static/robots.txt;
        }

        location / {
            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://frontends;
        }
    }
