centos5.4+nginx-0.8.50+uwsgi-0.9.6.2+django-1.2.3 build high-performance Web server _linux

Using nginx+fastcgi to build a Python Web server, this article describes the NGINX+UWSGI combination. Uwsgi is a fast, pure C language developed, self-maintained, developer-friendly WSGI server designed to provide professional Python Web application publishing and development. It is more compliant with the Python Web's standard protocol, faster than fastcgi, and more stable in performance.

Second, platform configuration

1, Platform Environment description
1.1, Project location:/opt/www/purgesys
To create a project method:

Copy Code code as follows:

Cd/opt/www
django-admin.py Startproject Purgesys

1.2, view the project (the following file structure shows that the project has been successfully created)
#tree Purgesys

Copy Code code as follows:

Purgesys
|--__init__.py
|--manage.py
|--settings.py
'--urls.py

2, Nginx related configuration

#cd/usr/local/nginx/conf
#vi django_uwsgi.conf

# Django Project Server {        listen  80;    


     server_name purgesys.domain.com;         location/{        
    uwsgi_pass   127.0.0.1:9000;             include     Uwsgi_
Params
            access_log  off;        &NBSP}         location ^~/ static {                root
  /opt/www/purgesys;        &NBSP}         location ^~/ admin/{         &NBsp;  uwsgi_pass   127.0.0.1:9000;
            include  uwsgi_params;
            access_log   off;        &NBSP}         location ~* ^.+ \. (mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|txt|tar|mid|midi|wav|rtf|mpeg) $ {    
        root  /opt/www/purgesys/static;
            access_log   off;        &NBSP}}

*nginx-0.8.50 default has been added Uwsgi output header support
include Uwsgi_params;

#vi nginx.conf
Append Child configuration file django_uwsgi.conf

http{..... 
Include django_uwsgi.conf; 

3, UWSGI Configuration
#mkdir-P/home/uwsgi;cd/home/uwsgi
#mkdir-P/opt/www/logs
#echo "" >/opt/www/logs/django.log
#vi Uwsgi.xml

<uwsgi>
 <socket>127.0.0.1:9000</socket>
 <listen>200</listen>
 < master>true</master>
 <pidfile>/usr/local/nginx/uwsgi.pid</pidfile>
 <processes >8</processes>
 <pythonpath>/opt/www/Purgesys</pythonpath>
 <pythonpath>/opt/ www/</pythonpath>
 <module>django_wsgi</module>
 <profiler>true</profiler>
 <memory-report>true</memory-report>
 <enable-threads>true</enable-threads>
 <logdate>true</logdate>
 <limit-as>6048</limit-as>
 <daemonize>/ Opt/www/logs/django.log</daemonize>
</uwsgi>

4. Create Application Module
Cd/opt/www/purgesys
VI django_wsgi.py

Import os
os.environ[' django_settings_module '] = ' purgesys.settings '
import Django.core.handlers.wsgi
application = Django.core.handlers.wsgi.WSGIHandler ()

5, start the service
#/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
#/usr/local/nginx/sbin/nginx

6, view the process
#[liuts@webserver nginx]# ps-ef|grep uwsgi|grep-v grep

Copy Code code as follows:

Root 21652 1 0 17:12? 00:00:00/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
Root 21653 21652 0 17:12? 00:00:00/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
Root 21654 21652 0 17:12? 00:00:00/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
Root 21655 21652 0 17:12? 00:00:00/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml

Root 21660 21652 0 17:12? 00:00:00/usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml

7. Listening Port
#[liuts@webserver nginx]# Netstat-an|grep 9000
Reference

TCP 0 127.0.0.1:9000 0.0.0.0:* LISTEN

8. Access Test
Input http://serverip/

Done!

* Attach Uwsgi startup script
#cd/home/uwsgi
#vi uwsgiserver.sh

#!/bin/bash
If [$ = start];then
 psid= ' ps aux|grep ' uwsgi ' |grep-v ' grep ' |wc-l '
 if [$psid-gt 2];then
   
    echo "Uwsgi is running!"
 Exit 0
 Else
 /usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
 fi
 echo "Start uwsgi service [OK]"
elif [$ = s Top];then
 killall-9 uwsgi
 echo "Stop uwsgi service [OK]"
elif [$ = restart];then killall-9 uwsgi
 /usr/bin/uwsgi-x/home/uwsgi/uwsgi.xml
 echo "Restart Uwsgi service [OK]"
else
 echo "Usages:sh uwsgiserver.sh [Start|stop|restart] "
fi
   

#sh uwsgiserver.sh Start
[Uwsgi] parsing config file/home/uwsgi/uwsgi.xml
Start UWSGI Service [OK]

The following are supplementary:

1, Mysql-python installation error is as follows
From Setuptools Import Setup Importerror:

Install first
Python ez_setup.py

In the installation
Python setup.py Install

Put it on the other brothers.

2, my Nginx+uwsgi+django encountered large header request, often appear 502,UWSGI reported is invalid request header size, how to solve my uwsgi configured as [Uwsgi]socket = : 8010master = Truemodule = django_wsgiprocesses = 8home =/path/to/virtualenvharakiri = 20daemonize =/path/to/uwsgi.logpi Dfile =/path/to/uwsgi.pidpythonpath =/path/to/projectpythonpath =/path/to/uwsgibuffer-size = 32768reload-mercy = 8max-requests = 5000socket-timeout = 4

Workaround: The large header can modify the Nginx HTTP head part parameters.

3, Nginx reported 502, but uwsgi normal boot port 9000 also normal monitoring. It is possible that an application has an error cause.
