基于python的web項(xiàng)目，常見的部署方法有：

不過還有個(gè)uwsgi，它既不用wsgi協(xié)議也不用fcgi協(xié)議，而是自創(chuàng)了一個(gè)uwsgi的協(xié)議，據(jù)作者說該協(xié)議大約是fcgi協(xié)議的10倍那么快。uWSGI的主要特點(diǎn)如下：

環(huán)境ubuntu 12.04 IP:10.1.6.79

安裝nginx

apt-get install nginx-full nginx-common

nginx配置/etc/nginx/sites-enabled/example

server {    listen     80;    server_name   10.1.6.79;    access_log   /var/log/nginx/example_access.log;    error_log    /var/log/nginx/example_error.log;    root      /var/www/example;    location / {      uwsgi_pass   127.0.0.1:9001;      include     uwsgi_params;      uwsgi_param   UWSGI_SCHEME $scheme;      uwsgi_param   SERVER_SOFTWARE  nginx/$nginx_version;    }}

安裝uwsgi

apt-get install uwsgi uwsgi-plugin-python

    如果你想安裝所有的uwsgi插件，則可以安裝uwsgi-plugin-all軟件包

uwsgi配置/etc/uwsgi/apps-enabled/default.xml

<uwsgi>  <plugin>python</plugin>  <socket>127.0.0.1:9001</socket>  <pythonpath>/var/www/example/app/</pythonpath>  <app mountpoint="/">    <script>wsgi_configuration_module</script>  </app>  <master/>  <processes>4</processes>  <reload-mercy>8</reload-mercy>  <cpu-affinity>1</cpu-affinity>  <max-requests>2000</max-requests>  <limit-as>512</limit-as>  <reload-on-as>256</reload-on-as>  <reload-on-rss>192</reload-on-rss>  <no-orphans/>  <vacuum/></uwsgi>

    uwsgi配置文件中的參數(shù)也可以在命令行通過uwsgi指定，配置文件除了xml格式外，還可以寫成ini格式的，軟件包安裝完畢后在/usr/share/doc/uwsgi/examples/conffile目錄下會有一些xml和ini格式配置文件的例子。

wsgi_configuration_module.py腳本內(nèi)容
