This article mainly introduces Python how to achieve WEB, the article is very detailed, has a certain reference value, interested friends must read it!

Python implements the WEB test environment:

Server configuration: 4 x Intel (R) Xeon (R) CPU E5405 @ 2.00GHz, 4G memory, operating system: CentOS 5.3 x 86 / 64

Nginx front end + 4 tornado (0.2) web process

Tornado: http://www.tornadoweb.org (has been walled)

Python implements the WEB test scenario:

Http get request. Server returns "hello world" directly.

Python implements WEB code and nginx configuration:

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 var/run/nginx.pid; events 8081; server 127.0.0.1 VR 8082; server 127.0.1 VR 8083; server 127.0.0.1 var/nginx_error.log; pid 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; gzip_min_length 1000; gzip_proxied any; gzip_types text/plain text/html text/css text/xml 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;} these are all the contents of the article "how Python implements WEB".
