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_64nginx前端 + 4 tornado(0.2) web process
tornado: http://www.tornadoweb.org (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;
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;
}
}
}
测试结果:
点击率可以超过7000,但后面再加用户开始往下掉,请求开始出错,最合适的时候大概3500个用户
持续运行后,连接数稳在1万。
