Flask+uwsgi+Nginx环境搭建

1. 开源软件准备
   需要的软件列表：
   setuptools-33.1.1.zip
   Python-2.7.13.tgz
   pip-9.0.1.tar.gz
   nginx-1.10.3.tar.gz
   软件统一上传到/usr/local/src/下，python是使用自己编译的。
   
2. Python安装

   先安装以下的软件（如果有的话，就可以不安装了，例如使用rpm -qa zlib-devel先查看下）
   yum install zlib-devel -y
   yum install openssl-devel -y

   tar -zxvf解压
   ./configure --prefix=/usr/local/python #安装到/usr/local/python目录下。
   make 
   make install

3. setuptool和pip安装
   unzip解压setuptool
   /usr/local/python/bin/python setup.py install
   
   tar -zxvf解压pip
   /usr/local/python/bin/python setup.py install
    
4. flask和uwsgi安装
   使用pip安装flask和uwsgi
   /usr/local/python/bin/pip install flask
   /usr/local/python/bin/pip install uwsgi
5. nginx安装

   先安装pcre-devel：
   yum install pcre-devel -y

   ./configure --prefix=/usr/local/nginx
   make && make install

6. nginx使用uwsgi配置

   cat /usr/local/nginx/conf/nginx.conf

   #user  nobody;
   worker_processes  1;
   
   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"‘;
       sendfile        on;
       keepalive_timeout  65;
       server {
           listen       8080;
           access_log  /usr/local/nginx/logs/flask_access.log main;
           error_log /usr/local/nginx/logs/flask_error.log error;
           client_max_body_size 200M;
           location / {
               include      uwsgi_params;
               uwsgi_pass   unix:/dev/shm/uwsgi.sock;
               index  index.html index.htm;
           }
       }
   
   }

   
   启动nginx：
   /usr/local/nginx/sbin/nginx  -t
   /usr/local/nginx/sbin/nginx

   注意：uwsgi_pass   unix:/dev/shm/uwsgi.sock;需要和uwsgi的配置相对应！

7. uwsgi配置
   cat /root/uwsgi.ini

   [uwsgi]
   uid = root
   gid = root
   socket = /dev/shm/uwsgi.sock
   chmod-socket = 666
   enable-threads = true
   master = true
   plugins = /usr/local/python/bin/python
   vhost = true
   workers = 5
   max-requests = 1000
   pidfile = /var/run/uwsgi.pid
   daemonize = /var/log/uwsgi.log
   chdir = /root/ops_dev/
   module = ops_dev
   callable = app

   启动uwsgi，有些报错没什么事：
   /usr/local/python/bin/uwsgi /root/uwsgi.ini
   

8. 编写测试样例进行测试

   cat /root/ops_dev/ops_dev.py

   # -*- coding: UTF-8 -*-
   from flask import Flask
   app = Flask(__name__)
   
   @app.route(‘/‘, methods=[‘GET‘, ‘POST‘])
   def index():
       return ‘Hello  world,Python ops_dev!‘

   编写完需要重启uwsgi，开改动代码都需要重启uwsgi，直接使用pkill进行重启即可:
   pkill uwsgi
   
   访问http://localhost:8080/进行测试。
   
   
   访问日志记录(nginx和uwsgi的访问日志，可用来排错。)：
