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

Question

我有两个 Flask 应用程序，我想将它们托管在同一个网络服务器上。
我已经成功获得其中之一运行，但我似乎无法同时获得两者。

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

中的设置

我的nginx配置和uwsgi ini文件是一样的；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，例如"request" 或 "demoapp" 我的其他应用。

我的请求应用的 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;
    }
}

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

这条线让我的应用程序正常工作

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

如果我为我的其他应用程序关闭 "request"，其他应用程序就会正常工作。

我的 nginx error.log 显示当我在启用站点时同时拥有两个配置文件时，我得到这个

2015/05/07 10:03:45 [warn] 7527#0: conflicting server name "localhost" on 0.0.0.0:80, ignored

"argonaut"是我服务器的名字

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

更新我正在考虑放弃并在我的服务器上设置一个带有单独 nginx 的虚拟机来托管多个应用程序。

谢谢！

在 nginx 中，您可以通过更改 server_name 来重复服务器组件。操纵 server_name 可以来自简单的 dns A 记录或 CNAME。请参阅以获得完整答案/
