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
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
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
