nginx+django+uwsgi

最近来了兴致，想搞一下django开发，so, 搭建一下环境

1、安装django，可能通过pip install 或者源码安装（因为环境是python2.6.6的环境，所以这里采用django 1.4.17的版本）:

# tar zxvf Django-1.4.17
# cd Django-1.4.17
# python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/bin/django-admin.py to 755
running install_data
running install_egg_info
Removing /usr/lib/python2.6/site-packages/Django-1.4.17-py2.6.egg-info
Writing /usr/lib/python2.6/site-packages/Django-1.4.17-py2.6.egg-info

因为之前安装了一次所以输出比较少

# python
Python 2.6.6 (r266:84292, Jan 22 2014, 09:42:36)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.VERSION
(1, 4, 17, 'final', 0)

2、安装uwsgi。uwsgi是一个快速的，纯C语言开发的，自维护、对开发者友好的WSGI服务器，旨在提供专业的python web应用发布和开发功能

# tar zxvf uwsgi-2.0.9.tar.gz
# cd uwsgi-2.0.9
socket/plugin.o -lpthread -lm -rdynamic -ldl -lz -L/usr/local/lib -lpcre -lssl -lcrypto -lxml2 -lz -lm -lpthread -ldl -lutil -lm -lpython2.6 -lcrypt
################# uWSGI configuration #################

pcre = True
kernel = Linux
malloc = libc
execinfo = False
ifaddrs = True
ssl = True
zlib = True
locking = pthread_mutex
plugin_dir = .
timer = timerfd
yaml = embedded
json = False
filemonitor = inotify
routing = True
debug = False
capabilities = False
xml = libxml2
event = epoll

############## end of uWSGI configuration #############
total build time: 1 seconds
*** uWSGI is ready, launch it with ./uwsgi ***

# cp uwsgi /usr/bin
# cd ..

如果在这个过程中遇到下面错误，可以执行yum remove pcre-devel 然后再执行：

c:undefined reference to `pcre_free_study'
collect2: ld returned 1 exit status
*** error linking uWSGI ***
make: *** [all] Error 1

也可以使用pip进行安装：

# pip install uwsgi
Requirement already satisfied (use --upgrade to upgrade): uwsgi in /usr/lib/python2.6/site-packages
Cleaning up...

3、nginx配置

nginx的安装，我们在这里就不讲了，经常做的工作，相必大家都会，下面看一下vhost的配置：

# cat localhost.conf
server{
listen 80;
server_name localhost;
location / {
uwsgi_pass 127.0.0.1:9090;
include uwsgi_params;
uwsgi_param UWSGI_CHDIR  /data/www/OMserverweb;
uwsgi_param UWSGI_SCRIPT django_wsgi;
access_log off;
}
location ^~ /static{
root /data/www/OMserverweb/OMserverweb;
}
location ~* ^.+.(mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|txt|tar|mid|midi|wav|rtf|mpeg)$ {
root /data/www/OMserverweb/OMserverweb/static;
access_log off;
}
}

4、配置uwsgi。创建uwsgi配置文件/data/nginx/config/uwsgi.ini,详细内容如下：

# cat uwsgi.ini
[uwsgi]
socket = 127.0.0.1:9090
master = true
pidfile = /var/run/uwsgi.pid
processes = 8
chdir = /data/www/OMserverweb
pythonpath = ..
profiler = true
memory-report=true
enable-threads=true
logdate=true
limit-as=6048
daemonize=/data/nginx/logs/django.log

进入到网站根目录/data/www:

# django-admin.py startproject OMserverweb
# tree
.
├── django_wsgi.py
├── django_wsgi.pyc
├── manage.py
└── OMserverweb
├── __init__.py
├── __init__.pyc
├── settings.py
├── settings.pyc
├── urls.py
├── urls.pyc
├── wsgi.py
└── wsgi.pyc

创建django_wsgi：

# cat django_wsgi.py
#!/usr/bin/env python
# coding: utf-8

import os
import sys

# 将系统的编码设置为UTF8
reload(sys)
sys.setdefaultencoding('utf8')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "OMserverweb.settings")

from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()

5、启动：

# uwsgi --ini /data/nginx/conf/uwsgi.ini
# /etc/init.d/nginx restart
Stopping nginx:                                            [  OK  ]
Starting nginx:                                            [  OK  ]

# ps aux | grep uwsgi

root     10164  0.0  0.9 221552 18300 ?        S    11:32   0:00 uwsgi --ini /data/nginx/conf/uwsgi.ini
root     10165  0.0  0.7 215352 14252 ?        S    11:32   0:00 uwsgi --ini /data/nginx/conf/uwsgi.ini

root     29104  0.0  0.0 103240   864 pts/0    S+   13:18   0:00 grep uwsgi

打开网页输入域名:

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 OMserverweb/settings.py.
Start your first app by running python manage.py startapp [appname].
You're seeing this message because you have DEBUG = True in your Django settings file and you haven't configured any URLs. Get to work!

说明环境搭建成功
