nginx+多uwsgi的配置

测试下nginx+多uwsgi的配置.

一个flask项目：

wangxh@mac : ~/myapp/myhome$ tree
.
├── __init__.py
├── s.ini
├── s2.ini
├── templates
│   └── index.html
├── ui.py
└── ui.pyc

wangxh@mac : ~/myapp/myhome$ cat s.ini 
[uwsgi]
socket = /tmp/s.sock
master = true
module = ui
callable = app
uid = 4294967294
gid = 4294967294
buffer-size = 25000

wangxh@mac : ~/myapp/myhome$ cat s2.ini 
[uwsgi]
socket = /tmp/s2.sock
master = true
module = ui
callable = app
uid = nobody
gid = nobody
buffer-size = 25000


wangxh@mac : ~/myapp/myhome$ cat ui.py
#!/usr/bin/python
#coding=utf-8
import sys
sys.path.append('/Library/Python/2.7/site-packages')
from flask import Flask, request, render_template, redirect, url_for, session, flash
import flask
import jinja2
import datetime
import urlparse
import random
import hashlib
import re

app = Flask(__name__)
app.secret_key = '\x9a\xf8pJp\xbf\xbdBY\xb0\xfd\xa68\xac\x809j\x0c\xd6\x89\xc5,\xcf\xc2'

@app.route('/')
def index():
	return render_template("index.html")

if __name__ == "__main__":
	#app.debug = True
	app.run()

配置nginx：

wangxh@mac : ~/myapp/myhome$ cat /usr/local/nginx-1.3.6/conf/nginx.conf|grep -v '#'|grep -v '^$'
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
		upstream ui {
			server unix:///tmp/s.sock;
			server unix:///tmp/s2.sock;
		}
    server {
        listen       80;
        server_name  localhost;
        location / {
			include uwsgi_params;
			uwsgi_pass ui;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

运行,在两个终端中分别运行：

uwsgi --ini s.ini
uwsgi --ini s2.ini

重启nginx，然后再开一个终端执行：

wangxh@mac : ~$ while true;do curl -vv http://localhost/;sleep 1;done

再uwsgi终端即可观察到请求被均匀分布到两个uwsgi
