socket代理配置：

關於uwsgi的用法，請自行百度，這裡只針對socket檔案和埠的不同，進行單一的記錄。

這種方式啟動的flask應用，由於是通過socket與nginx通訊的，所以必須制定socket檔案，無法進行叢集部署：

uwsgi配置

[uwsgi]
#application's base folder
base = /data/www/myproject

#python module to import
app = manage
module = %(app)

home = %(base)/venv
pythonpath = %(base)

#socket file
 
's location
socket = /data/www/myproject/%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 = /data/www/log/uwsgi/%n.log

nginx配置：

server {
    listen      80;
    server_name localhost;
    charset     utf
 
-8;
    client_max_body_size 75M;
    location / {
        include uwsgi_params;
        uwsgi_pass unix:/data/www/myproject/myproject_uwsgi.sock;
    }
}

socket埠配置：

如果需要使用叢集，需要使用埠來與nginx進行通訊，那麼uwsgi的配置就會有些許的差異：

uwsgi配置

[uwsgi]
#application's base folder
base = /data/www/myproject

#python module to import
app 
 
= hello
module = %(app)

home = %(base)/venv
pythonpath = %(base)

#socket file's location
socket = :8080
#socket = /data/www/myproject/%n.sock
#permissions for the socket file
chmod-socket    = 644
#the variable that holds a flask application inside the module imported at line #6
callable = app
#location of log files
logto = /data/www/log/uwsgi/%n.log

差異就是將sock檔案，改為埠，當然也可以寫成如下格式：

socket = 0.0.0.0:8080
socket = 127.0.0.1:8080

那麼如果nginx需要負載兩臺甚至多臺server，就需要修改配置：

upstream ai-server {
        server server1:8080;
        server server2:8080;
}
server {
    listen      80;
    server_name localhost;
    charset     utf-8;
    client_max_body_size 75M;

    location / {
        include uwsgi_params;
        uwsgi_pass ai-server;
    }
}
