nginx mod_wsgi安装配置笔记

做个笔记，防止忘记。
安装环境: ubuntu8.04
首先确定有了python的头文件(/usr/include/python2.5)，没有的话apt一下:)
sudo apt-get install python2.5-dev
1.nginx安装 
  $ ./configure --add-module=/path/to/mod_wsgi/ --prefix=/usr/local/nginx
  $ make && make install

2.mod_wsgi安装
  $ cd mod_wsgi-0.0.6/
  $ sudo python setup.py --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/conf --sbin-path=/usr/local/nginx/sbin

3.打开/usr/local/nginx/conf/nginx.conf

user  nobody; #工作进程属主
worker_processes  2; #工作进程，一般的等于CPU核数
daemon off;           
master_process  on;

error_log  logs/error.log info;
pid        logs/nginx.pid;

events {
    use epoll;  #linux2.6+ 
    worker_connections  1024; # 每个工作进程允许最大的同时连接数
}


env HOME;
#可以将你的project加入python的sys.path
env PYTHONPATH=/path/to/your/project;
#解决python执行egg包的权限问题
env PYTHON_EGG_CACHE=/tmp;

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

    log_format  main  '$remote_addr - $remote_port - $remote_user [$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  off;
    #ssl on;
    #ssl_certificate      conf/server.crt;
    #ssl_certificate_key  conf/server.key;

    wsgi_python_optimize 2;
    wsgi_python_executable /usr/bin/python;
    #wsgi_python_home /usr;
    #wsgi_enable_subinterpreters on;

    server {
        listen       80;
        server_name  localhost;


        include conf/wsgi_vars;

        #wsgi_middleware  wsgiref.validate  validator;
        #wsgi_middleware  paste.lint;

        location / {
            #client_body_buffer_size 50;
            #你的 module path 和  WSGI application 的名称，默认是application， 我这里用的是mod_wsgi自带的examples。
            wsgi_pass /your/path/to/examples/nginx.py;

            wsgi_pass_authorization off;
            wsgi_script_reloading on;
            wsgi_use_main_interpreter on;
        }

        location /wsgi {
            #client_body_buffer_size 50;
            wsgi_var TEST test;
            wsgi_var FOO bar;
            wsgi_var EMPTY "";
            # override existing HTTP_ variables
            wsgi_var HTTP_USER_AGENT "nginx";
            wsgi_var HTTP_COOKIE  $http_cookie;

            wsgi_pass /your/path/to/examples/nginx-2.py  main;

            wsgi_pass_authorization on;
            wsgi_script_reloading off;
            wsgi_use_main_interpreter on;
        }
    }
}

4.启动nginx：
  $ cd /usr/local/nginx
  $ sudo sbin/nginx -c conf/nginx.conf
5.打开浏览器，输入http://127.0.0.1/wsgi/ 输出如下内容：
