简单部署流程：

1、在centos安装python及pip，

pip安装地址：http://pip.readthedocs.org/en/latest/installing.html

安装步骤比较简单，执行：

python get-pip.py

2、安装flask和uwsgi包，命令如下：

pip install uwsgi

pip install flask

3、添加flask的文件，以hello world为例：

1
2
3
4
5
6
7
8
9
from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello World!'

if __name__ == '__main__':
    app.run()

保存为hello_flask.py文件，然后添加run文件：

1
2
3
from hello_flask import app
if __name__ == "__main__":
    app.run()

保存为 WSGI.py 文件

4、配置uwsgi，添加uwsgi配置文件：

[uwsgi]
#application's base folder
base = /var/python/hello_flask

#python module to import
app = hello_flask
module = WSGI

pyargv = -e Production
pythonpath = %(base)

#socket file's location
socket = /tmp/%n.sock

#permissions for the socket file
chmod-socket    = 666

#the variable that holds a flask application inside the module imported at line #6
callable = app

#location of log files
logto = /var/python/hello_flask/%n.log

保存为flask_uwsgi.ini

5、最后配置nginx，相关配置如下：

server{
    server_name www.helloflask.com;
    listen 80;

    root /var/python/hello_flask;

    location ~ ^/static/ {
        root /var/python/hello_flask;
        access_log off;
        expires 4d;
    }

    location / { try_files $uri @hello; }
    location @hello{
        include uwsgi_params;
        uwsgi_pass unix:/tmp/flask_uwsgi.sock;
        proxy_redirect     off;
        proxy_set_header   Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Host $server_name;
    }
}

然后重启启动nginx，加载配置

6、最后启动uwsgi服务，让外网能够访问

uwsgi -d –ini flask_uwsgi.ini

这样就在后台启动uwsgi服务，至此简单配置完毕，外网就可以访问我们的flask网站了。
