uWSGI+Nginx安装、配置

1、关闭SELINUX：

[root@PYTHON27 /]# vim /etc/selinux/config

将SELINUX=enforcing修改为SELINUX=disabled

2、关闭防火墙：

[root@PYTHON27 /]# service iptables stop
[root@PYTHON27 /]# chkconfig iptables off

3、安装EPEL源：

[root@PYTHON27 /]# yum -y install epel-release
[root@PYTHON27 /]# yum clean all
[root@PYTHON27 /]# yum makecache

4、安装系统工具：

[root@PYTHON27 /]# yum -y install vim wget telnet

5、安装编译支持包：

[root@PYTHON27 /]# yum -y install gcc gcc-c++ automake autoconf

6、安装Nginx支持包：

[root@PYTHON27 /]# yum -y install zlib zlib-devel pcre pcre-devel openssl openssl-devel

7、安装uwsgi及组件：

[root@PYTHON27 /]# yum -y install uwsgi uwsgi-devel uwsgi-plugin-python

8、查看uwsgi版本：

[root@PYTHON27 /]# uwsgi --version
2.0.14

9、启动uwsgi项目：

[root@PYTHON27 /]# uwsgi --ini /usr/local/src/python-test/python-test.ini

10、解压nginx安装包：

[root@PYTHON27 /]# tar -xzvf /usr/local/src/nginx-1.10.1.tar.gz -C /usr/local/src/

11、编译、安装：

[root@PYTHON27 /]# cd /usr/local/src/nginx-1.10.1
[root@PYTHON27 nginx-1.10.1]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module
[root@PYTHON27 nginx-1.10.1]# make -j 2
[root@PYTHON27 nginx-1.10.1]# make install

12、修改Nginx配置文件：

[root@PYTHON27 /]# vim /usr/local/nginx/conf/nginx.conf

将下边内容：
        location / {
            root   html;
            index  index.html index.htm;
        }
        
替换为：

        location / {
                include uwsgi_params;
                uwsgi_read_timeout 3600;
                uwsgi_pass 127.0.0.1:9090;
        }

13、启动nginx服务：

[root@PYTHON27 /]# /usr/local/nginx/sbin/nginx -t
[root@PYTHON27 /]# /usr/local/nginx/sbin/nginx

14、测试：

[root@PYTHON27 /]# curl http://192.168.75.150/
Hello World

源码:

python-test.py:

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

python-test.ini:

[uwsgi]
socket = 127.0.0.1:9090
wsgi-file = /usr/local/src/python-test/python-test.py
plugins = python
chdir = /usr/local/src/python-test
processes = 2
threads = 2
post-buffering = 8192
buffer-size = 65535
socket-timeout = 10
stats = 127.0.0.1:9191
# callable = python-test
uid = uwsgi
gid = uwsgi
master = true
protocol = uwsgi
buffer-size = 8192
pidfile = /var/run/uwsgi9090.pid
# daemonize = /var/log/uwsgi9090.log

注释： socket = 127.0.0.1:9090　　##启动端口9090的服务，需用nginx代理，可以对外提供服务。

　　　 http-socket = 127.0.0.1:9090　　##启动端口9090的服务，可以直接对外提供服务。

python-test.py:通过WEB页面执行服务器上的脚本：

import os

def application(env, start_response):
    os.chdir('/usr/local/src/python-test')
    retcode = os.system('sh dir.sh')
    if retcode == 0:
        ret = 'success!'
    else:
        ret = 'failure!'
        start_response('200 OK', [('Content-Type','text/html')])
    return [ret]

[END]
