Nginx+uWSGI或fastcgi部署Django项目

nginx+uWSGI

ubuntu下先安装下C编译器和Python环境:

sudo apt-get install build-essential python-dev

使用pip安装uWSGI:

pip install uwsgi

nginx配置:

可以单独为站点设置一个配置文件:

sudo vim /etc/nginx/sites-enabled/mysite

或者直接在nginx.conf中设置:

sudo vim /etc/nginx/nginx.conf

设置:

server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6
 
    server_name 站点域名;
    location / {
            uwsgi_pass 127.0.0.1:8080;
            include uwsgi_params;
    }
    #设置该网站应用中所需要的静态文件的根目录,需要将admin和用到的第三方库像restframework的静态文件都放到此目录中
     location ~/static/ {
            root   /home/user/mysite/;  #项目地址
           # root  html;
           # index  index.html index.htm;
            break;
        }
        #设置媒体文件的根目录
       location ~/media/ {
            root   /home/user/mysite/;
           # root  html;
           # index  index.html index.htm;
            break;
        }
}

自己电脑上搭建localhost服务器时,注意别被/etc/nginx/sites-enabled/default中的配置覆盖掉了,最好将其注释掉。

然后设置uWSGI,建立文件myfile.ini:

[uwsgi]
socket = 127.0.0.1:8080   #与nginx配置中的uwsgi_pass相同
chdir = /home/user/mysite/    #项目地址
wsgi-file = mysite/wsgi.py
processes = 4
threads = 2
pidfile=/tmp/project-master.pid
stats = 127.0.0.1:9191
virtualenv = <path to env> #virtualenv

其中wsgi-file是django(1.4版本以上)项目自动建立的文件,里面内容为:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "weixian.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

如果django版本过低无此文件的话,可以自己建立,或者在myfile.ini中设置env,module,pythonpath:

[uwsgi]
socket = 127.0.0.1:8080
chdir = /home/user/mysite/
pythonpath = ..
env = DJANGO_SETTINGS_MODULE=mysite.settings
module = django.core.handlers.wsgi:WSGIHandler()
processes = 4
threads = 2
stats = 127.0.0.1:9191
virtualenv <path to env>

按配置重启nginx:

/usr/sbin/nginx -s reload

或者:

killall -9 nginx
nginx -c /etc/nginx/nginx.conf

启动uWSGI:

uwsgi myfile.ini

重启uWSGI:

# using kill to send the signal
kill -HUP `cat /tmp/project-master.pid`
# or the convenience option --reload
uwsgi --reload /tmp/project-master.pid
# or if uwsgi was started with touch-reload=/tmp/somefile
touch /tmp/somefile

ini文件也可以用xml文件来设置。

添加xml支持:

sudo apt-get install libxml2-dev

配置myfile.xml

<uwsgi>
    <socket>127.0.0.1:8080</socket>
    <chdir>/home/user/mysite/</chdir>
    <module>mysite/wsgi</module>
</uwsgi>

启动:

uwsgi -x myfile.xml

nginx+fastcgi

fastcgi需要安装flup:

wget http://www.saddi.com/software/flup/dist/flup-1.0.2.tar.gz
tar zxvf flup-1.0.2.tar.gz
cd flup-1.0.2
python setup.py install

或者:

sudo apt-get install  python-flup

nginx配置:

server {
        listen       80;
        server_name  localhost;

        #设置该网站应用中所需要的静态文件的根目录
        location ~/static/ {
            root   /home/user/mysite/;
           # root  html;
           # index  index.html index.htm;
            break;
        }
        #设置媒体的根目录
        location ~/media/ {
            root   /home/user/mysite/;
           # root  html;
           # index  index.html index.htm;
            break;
        }
        #host and port to fastcgi server 
        location / {
        fastcgi_pass 127.0.0.1:8080;
        fastcgi_param PATH_INFO $fastcgi_script_name;
        fastcgi_param REQUEST_METHOD $request_method;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_param CONTENT_TYPE $content_type;
        fastcgi_param CONTENT_LENGTH $content_length;
        fastcgi_param pass_header Authorization;
        fastcgi_intercept_errors off; 
        }
        #设置浏览器缓存这些图片格式文件浏览器缓存时间是30天,css/js缓存时间1小时
        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires 30d;
        }

        location ~ .*\.(js|css)?$
        {
            expires 1h;
        }
}

重启nginx,然后启动fcgi:

python manage.py runfcgi host=127.0.0.1 port=8080 method=prefork --settings=mysite.settings  #采用静态进程池的话性能会比动态线程生成高2倍左右

ok。

要更新django项目的话,

ps -ef |grep fcgi 

找出主进程号kill掉,再重启fcgi即可。

也可以写个重启脚本。使用pidfile选项将fcgi的pid存储到文件中,重启时读取kill掉。

#!/bin/bash

PROJDIR="/home/user/myproject"
PIDFILE="$PROJDIR/mysite.pid"

cd $PROJDIR
if [ -f $PIDFILE ]; then
    kill `cat -- $PIDFILE`
    rm -f -- $PIDFILE
fi

exec python manage.py runfcgi host=127.0.0.1 port=8080 method=prefork pidfile=$PIDFILE --settings=mysite.settings
