在ubuntu上为多个uwsgi-emperor flask应用程序配置nginx

Question

我有两个烧瓶应用程序，我想在同一台Web服务器上托管。
我已经成功运行了一个或另一个，但是似乎无法同时运行两个。

我使用了来自http://vladikk.com/2013/09/12/serving-flask-with-nginx-on-ubuntu/的设置

我的nginx config和uwsgi ini文件是相同的； 除了我根据应用程序和文件夹结构替换不同的文件夹名称外，例如为其他应用程序使用“ request”或“ demoapp”。

我的请求应用程序的Nginx配置文件是

server {
    listen      80;
    server_name localhost;
    charset     utf-8;
    client_max_body_size 75M;

    location / { try_files $uri @yourapplication; }
    location @yourapplication {
        include uwsgi_params;
        uwsgi_pass unix:/var/www/request/request_uwsgi.sock;
    }
}

而我的uwsgi ini文件是

[uwsgi]
#application's base folder
base = /var/www/request

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

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

#socket file's location
socket = /var/www/request/%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/log/uwsgi/%n.log

这条线使我的应用程序正常工作

/etc/nginx/sites-enabled$ uwsgi --ini /var/www/request/request_uwsgi.ini

如果我关闭其他应用程序的“请求”，则其他应用程序正常工作。

我的nginx error.log显示，当我在启用站点的两个配置文件中都得到此信息时

“ argonaut”是我的服务器的名称

我找不到任何人运行两个flask应用程序的任何配置示例，甚至找不到如何编写conf文件的很好的解释。

更新我正在考虑放弃并在服务器上设置带有单独的nginx的虚拟机，以托管多个应用程序。

谢谢！

在nginx中，您可以通过更改server_name来重复服务器组件。 可以通过简单的dns A Record或CNAME来操作server_name。 有关完整答案，请参见https://stackoverflow.com/a/27221427/567606/
