uwsgi安装及配置搭档nginx

环境比较奇葩 

Centos5.6  + python 2.7.8

于是有很多问题。

1.安装uwsgi

不能采用网上的方式：

easy_install   -->  pip  -->  安装uwcgi 

提示错误：warning: implicit declaration of function ‘accept4’

各种尝试都有错误

经过查询 系统库不支持：在accept4()用 linux 系统调用是可以启动 2.6.28 ;支持中 glibc 的版本开始 2.10.

参考：http://www.helplib.net/s/linux.die/65_318/man-2-accept4.shtml

只能降低版本，源码安装经测试：

wget http://projects.unbit.it/downloads/uwsgi-1.3.tar.gz
tar xzvf uwsgi-1.3.tar.gz
cd uwsgi-1.3
make
make install 

可以。

妈妈的热泪盈眶啊

2.安装nginx没什么难度掠过

3.配置nginx的uwsgi

server {
    listen       80;
    server_name  uwsgi.xx.com;
    index index.html index.htm index.php;
    root  /opt/wf_stats;
    access_log  logs/stats.access.log  main;
    error_log  logs/stats.error.log;

    location / {
        include  uwsgi_params;
        uwsgi_pass  127.0.0.1:9090;              #必须和uwsgi中的设置一致
        index  index.html index.htm;
        client_max_body_size 55m;
    }
}

这个是vhost 的配置，其他方式的类似

4.wgsgi的配置

[uwsgi]
socket = 127.0.0.1:9090
;主进程
master = true
;多站模式
vhost = true
;多站模式时不设置入口模块和文件
no-stie = true
;子进程数
workers = 2
reload-mercy = 10
;退出、重启时清理文件
vacuum = true
max-requests = 1000
limit-as = 512
buffer-sizi = 30000
wsgi-file = [path]/testUwsgi.py
;pid文件，用于下面的脚本启动、停止该进程
pidfile = /opt/modules/uwsgi/logs/uwsgi9090.pid
daemonize = /opt/modules/uwsgi/logs/uwsgi9090.log

5.wgsig测试

python测试文件：

def application(env, start_response):
        start_response('200 OK', [('Content-Type','text/html')])
        return "Hello World"

保存为testUwsgi.py

不需要nginx的测试

uwsgi --http :9090  --wsgi-file wsgi.py --master --processes 4 --threads 2 

6.wgsig的启动shell

#! /bin/sh
# chkconfig: 2345 55 25

# run 'update-rc.d -f uwsgi defaults', or use the appropriate command on your

uwsgi9090 start 启动uwsgi

可以了  启动nginx 和  uwsgi 浏览器中访问 

uwsgi.xx.com
