初试nginx+uwsgi+django[1]

环境
操作系统 centos 6.2 x64
—————————————

1.安装:

[nginx] 

    省略，只记录一下nginx版本和编译参数
     nginx  1.11 
     prefix=/usr/local/nginx –with-pcre=/usr/local/src/pcre-8.21 –with-http_stub_status_module –user=gameserver –group=gameserver –with-http_ssl_module
 

[python]

     centos 6.2 已经自带 python2.6 了，其他版本的话自己yum -y install python

[django]

  wget http://www.djangoproject.com/download/1.2.3/tarball/
  cd Django-1.2.3
  python setup.py  install
  安装成功会出现这个字样

        running install_egg_info
        Writing /usr/lib/python2.6/site-packages/Django-1.2.3-py2.6.egg-info

 

[uwsgi]

    wget  http://projects.unbit.it/downloads/uwsgi-0.9.6.8.tar.gz
    tar -zxvf  uwsgi-0.9.6.8.tar.gz
    cd uwsgi-0.9.6.8
    make

     出现报错[1] ******* libxml2 headers unavailable
     解决办法: yum -y install libxml2-devel

    继续make

     出现报错[2]

     wsgi.h:125:20: error: Python.h: No such file or directory
     In file included from utils.c:1:
     uwsgi.h:149: error: expected ‘)’ before ‘*’ token
     uwsgi.h:150: error: expected ‘)’ before ‘*’ token
     uwsgi.h:310: error: expected specifier-qualifier-list before ‘PyThreadState’
     uwsgi.h:492: error: expected specifier-qualifier-list before ‘PyThreadState’

     分析:

     查看/usr/include/python2.6目录，的确没有python.h

    解决办法:
      yum -y install python-devel

    继续make

    成功了,编译成功后出现以下字样

    *** uWSGI is ready, launch it with ./uwsgi ***

    cp  uwsgi /usr/local/uwsgi/bin/


2.配置:

 

[uwsgi]

  mkdir  -p  /usr/local/uwsgi/bin/
  mkdir  -p /usr/local/uwsgi/conf
  mkdir -p /usr/local/uwsgi/logs
  cd  /usr/local/uwsgi/conf
  vi  uwsgi.xml

 —
<uwsgi>
  <socket>127.0.0.1:9001</socket>
  <listen>200</listen>
  <master>true</master>
  <pidfile>/usr/local/uwsgi/logs/uwsgi.pid</pidfile>
  <processes>8</processes>
  <pythonpath>/usr/local/python_web/www</pythonpath>
  <pythonpath>/usr/local/python_web</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>/usr/local/uwsgi/logs/django.log</daemonize>
</uwsgi>

    创建应用模块

    mkdir -p /usr/local/python_web/
    cd  /usr/local/python_web/
    django-admin.py startproject  www

   ( 注:要看到www目录下的这几个文件才算成功 __init__.py  manage.py  settings.py  urls.py)

   cd /usr/local/python_web/www/
   vi django_wsgi.py

—

import os
os.environ['DJANGO_SETTINGS_MODULE'] = ‘www.settings’
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

–

[nginx]

server {
    listen  80;
    server_name xx.com;
    location / {
            uwsgi_pass   127.0.0.1:9001;
            include     uwsgi_params;
        }
 }


3.启动服务

/usr/local/uwsgi/bin/uwsgi -x /usr/local/uwsgi/conf/uwsgi.xml

检查启动状态

netstat -tunlp |grep 9001

tcp        0      0 127.0.0.1:9001              0.0.0.0:*                   LISTEN      8830/uwsgi

 

测试访问

配置 xx.com的host之后，访问 http://xx.com

就可以看到页面

————————-
It worked!
Congratulations on your first Django-powered page.

Of course, you haven’t actually done any work yet. Here’s what to do next:

    If you plan to use a database, edit the DATABASES setting in www/settings.py.
    Start your first app by running python www/manage.py startapp [appname].

这样就算成功了
但是到了这里，我其实还不是很懂 uwsgi ,django,nginx 之间的关系
我暂时理解为 nginx 和 uwsgi 的关系，就好像 nginx 和 fastcgi 一样， uwsgi 为nginx  解析python程序
