CentOS下Nginx+fastcgi+python3搭建web.py服务环境

我的系统环境是CentOS release 6.6(Final)

环境依赖软件包

1、python3
2、Nginx1.4（需要包含fastcgi和rewrite模块）
3、web.py-python3(https://github.com/webpy/webpy/tree/python3)
4、Spawn-fcgi 1.6.3
5、Flup6

软件包安装

python3.6安装

[root@localhost home]# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz
[root@localhost home]# tar xJf Python-3.6.1.tar.xz
[root@localhost Python-3.6.1]# cd Python-3.6.1.tar.xz
[root@localhost Python-3.6.1]# ./configure --prefix=/usr/local/python3 && make && make install
#创建软连接
[root@localhost Python-3.6.1]# ln -s /usr/local/python3/bin/python3 /usr/bin/python3
[root@localhost Python-3.6.1]# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

nginx安装
可以参考CentOS6.6环境中安装Nginx详细过程笔记博客文章
安装spawn-fcgi
[root@localhost home]# wget http://www.lighttpd.net/download/spawn-fcgi-1.6.3.tar.gz
[root@localhost home]# tar zxvf spawn-fcgi-1.6.3.tar.gz
[root@localhost spawn-fcgi-1.6.3]# ./configure && make && make install
安装flup6
[root@localhost ~]# pip3 install flup6
安装web.py
[root@localhost home]# wget https://github.com/webpy/webpy/archive/python3.zip
[root@localhost home]# unzip webpy-python3.zip
[root@localhost home]# cd webpy-python3

[root@localhost webpy-python3]# python3 setup.py install

配置

Nginx配置文件如下：

#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  65;

    #gzip  on;

    server {
        listen      80;
        server_name  pw.com;
        root /home/www/test;

        location / {
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
            fastcgi_param PATH_INFO $fastcgi_script_name;   
            fastcgi_pass 127.0.0.1:9002;
        }

        error_page  500 502 503 504  /50x.html;
        location = /50x.html {
            root  html;
        }

        location /static/ {
            if (-f $request_filename) {
                rewrite ^/static/(.*)$  /static/$1 break;
            }
        }
    }

}

在/home/www/demo目录下创建index.py
注意: 需要给代码设置执行权限，chmod +x index.py。

#!/usr/bin/env python3

# -*- coding: utf-8 -*-

import web

urls = ("/.*", "hello")

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

class hello:

    def GET(self):
        return 'Hello, world!'

if __name__ == "__main__":
    web.wsgi.runwsgi = lambda func, addr=None: web.wsgi.runfcgi(func, addr)
    app.run()

软件启动
Nginx启动
[root@localhost ~]# /usr/local/nginx/nginx
[root@localhost ~]# /usr/local/nginx/nginx -s reload #重启nginx配置
[root@localhost ~]# /usr/local/nginx/nginx -s stop #停止nginx
Spawn-fcgi启动
注意：你可以随意填写地址和端口信息，但是一定需要和Nginx配置文件相匹配
[root@localhost ~]# spawn-fcgi -d /home/www/demo -f /home/www/demo/index.py -a 127.0.0.1 -p 9002
[root@localhost ~]# kill `pgrep -f "python3 /home/www/demo/index.py"` #关闭进程

测试
[root@localhost ~]# curl localhost
如果打印“hello world！”则表示环境搭建成功
