Nginx+uWSGI下配置多个virutalenv环境

Category: /knowledge /linux
Tags: linux nginx

调试 Nginx+uWSGI的时候碰到了很多的麻烦, 可真调试成功以后才发现原来文件这么简单. 可是很多参数都是要亲自试才行. “纸上得来终觉浅”啊.

这里列举了两种情况, 一种是只运行一个站点. 我最开始只想在自己的VPS上运行这种情况. 但是后来有朋友想借用一下空间, 而且负载很轻. 于是我就查了一下如何用一套Nginx+uWSGI支持两个站点.

One master website

Nginx.conf ————

server {
        listen       80;
        server_name  localhost;

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        location / {
           include        uwsgi_params;
           uwsgi_pass     127.0.0.1:9001;
           uwsgi_param UWSGI_PYHOME /home/c2/sites/myvirtualenv;
           uwsgi_param UWSGI_CHDIR /home/c2/workspace/blog-app;
           uwsgi_param UWSGI_SCRIPT conf.dispatch;
        }
    }

uwsgi

 NAME=uwsgi
 DESC=uwsgi
 HOME=/home/c2/sites/myvirtualenv
 PYTHONPATH=/home/c2/sites/myvirtualenv/conf
 MODULE=dispatch

 test -x $DAEMON || exit 0

 DAEMON_OPTS="-s 127.0.0.1:9001 -M 4 -t 30 -A 4 -p 4 
   -d /var/log/nginx/uwsgi.log 
   --pythonpath $PYTHONPATH 
   --virtualenv $HOME
   --module $MODULE"

Single Nginx+uWSGI, multiple websites

nginx.conf ————

server {
        listen       80;
        server_name  site1;

        access_log /var/log/nginx/site1_access.log;
        error_log /var/log/nginx/site1_error.log;

        location / {
           include        uwsgi_params;
           uwsgi_pass     127.0.0.1:9001;
           uwsgi_param UWSGI_PYHOME /home/c2/sites/site1;
           uwsgi_param UWSGI_CHDIR /home/c2/workspace/blog-app;
           uwsgi_param UWSGI_SCRIPT conf.dispatch;
        }
    }

server {
        listen       80;
        server_name  site2;

        access_log /var/log/nginx/site2_access.log;
        error_log /var/log/nginx/site2_error.log;

        location / {
           include        uwsgi_params;
           uwsgi_pass     127.0.0.1:9001;
           uwsgi_param UWSGI_PYHOME /home/c2/sites/site2;
           uwsgi_param UWSGI_CHDIR /home/c2/workspace/another-prj;
           uwsgi_param UWSGI_SCRIPT conf.dispatch;
        }
    }

uwsgi

所有的配置都体现在nginx.conf里, uwsgi就变得很简单. 但我有一个没弄明白的问题是如何设置log文件. 目前所有的log都放在一起了.

/etc/init.d/uwsgi

LOG=/var/log/nginx/uwsgi.log
NAME=uwsgi
DESC=uwsgi

test -x $DAEMON || exit 0

DAEMON_OPTS="-s 127.0.0.1:9001 -M 4 -t 30 -A 4 -p 4 
  --vhost --no-site -d $LOG"

conf/dispatch.py

import sys,os
import django.core.handlers.wsgi

sys.path.append('/home/c2/workspace')
sys.path.append('/home/c2/workspace/django_test')

os.environ['DJANGO_SETTINGS_MODULE'] = 'django_test.settings'

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