    生产中，常用nginx+uwsgi+webpy的方法进行环境部署，今天学习了一下怎么用这几个工具来部署网站，记录一下。

1、准备一个基于webpy的文件server.py

#!/usr/bin/python
import web

urls = ('/', 'Hello')

class Hello(object):
    def GET(self):
        return 'Hello world'

app = web.application(urls, globals())
application = app.wsgifunc()

2、安装uwsgi

sudo apt-get install uwsgi

3、安装uwsgi下的python插件

sudo apt-get install uwsgi-plugin-python

4、准备uwsgi的配置文件，假设为cf.ini

[uwsgi]
http-socket    = :9090
plugin    = python
wsgi-file = /media/sf_Desktop/process/server.py
process   = 3

5、利用uwsgi运行ini文件

uwsgi --ini cf.ini

6、检验网站是否运行

    在浏览器中输入127.0.0.1:9090即可。

7、配置nginx、修改cf.ini

    如果需要nginx和uwsgi沟通，那么修改配置cf.ini，将http-socket修改为，

socket = 127.0.0.1:9090

    同时直接替换你的nginx.conf文件，即

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  256;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            include /etc/nginx/uwsgi_params;
            uwsgi_pass 127.0.0.1:9090;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        #error_page   500 502 503 504  /50x.html;
        #location = /50x.html {
        #    root   html;
        #}

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

8、验证测试

    找一个浏览器，直接输入127.0.0.1，看看是否有打印输出。

a. 如果nginx需要重新配置，直接service nginx restart即可
b. 如果nginx输出错误，在/var/log/nginx/下错误日志输出
c. nginx.conf 一般保存在/etc/nginx下面
d. nginx的网页一般保存在/usr/share/nginx下面
e. 可以用nginx -t检验nginx.conf文件是否配置正确
