nginx+uwsgi部署多个python应用

2015-01-12 17:35:52

参考文章：

http://kb.cnblogs.com/page/86907/ (配置Nginx＋uwsgi更方便地部署python应用)

http://projects.unbit.it/uwsgi/wiki/VirtualHosting (uWSGI VirtualHosting Mode)

http://uwsgi-docs.readthedocs.org/en/latest/Configuration.html (Configuring uWSGI)

为了让多个站点共享一个uwsgi服务，必须把uwsgi运行成虚拟站点：去掉“-w myapp”加上”–vhost”

1

uwsgi -M -p 2 -t 30 --limit-as 128 -R 10000 -x /usr/local/nginx/conf/uwsgi.xml -d /tmp/uwsgi.log --vhost

然后必须配置virtualenv，virtualenv是python的一个很有用的虚拟环境工具。

1

easy_install virtualenv

然后设置一个/多个app基准环境

1

virtualenv /www/fabric-bolt/

应用环境，在此环境下安装的软件仅在此环境下有效

4

source /www/fabric-bolt/

pip install django

pip install mako

...

最后配置nginx，注意每个站点必须单独占用一个server

}

            server_name  app2.blogex.com;

            location / {

                root /www/fabric-bolt/lib/python2.7/site-packages/fabric_bolt/work;

                include   uwsgi_params;

                uwsgi_param UWSGI_CHDIR /www/fabric-bolt/lib/python2.7/site-packages/fabric_bolt/work;

                uwsgi_param UWSGI_SCRIPT django_wsgi;

                access_log /usr/local/nginx/logs/access.log;

        }

}

uwsgi.xml的配置

<uwsgi>

<pidfile>/usr/local/nginx/conf/uwsgi.pid</pidfile>

<socket>192.168.1.121:9001</socket>

<processes>4</processes>

<pythonpath>/www/fabric-bolt/lib/python2.7/site-packages</pythonpath>

<pythonpath>/www/fabric-bolt/lib/python2.7/site-packages/fabric_bolt</pythonpath>

<pythonpath>/www/fabric-bolt/lib/python2.7/site-packages/fabric_bolt/work</pythonpath>

<daemonize>/tmp/uwsgi.log</daemonize>

</uwsgi>

重启nginx服务，两个站点就可以共用一个uwsgi服务了。

结语：

上篇文章配置好了dns服务器，这里分别访问nginx虚拟主机app1.blogex.com跟app2.blogex.com，可以看到django应用：
