【问题描述】:
我正在尝试在 Ubuntu 服务器上部署 Flask 应用程序。我参考了this、this和this,在SO上发现了很多类似的问题,但我还是想不通。
我可以通过执行uwsgi siti_uwsgi.ini 并导航到http://server_IP_address:8080/ 从源目录手动运行它。但是当我尝试uwsgi --socket 127.0.0.1:3031 --wsgi-file views.py --master --processes 4 --threads 2 并导航到http://server_IP_address:3031 时,我什么也得不到。
如果我去siti.company.loc(我设置的DNS名称),有一个标准的Nginx 502错误页面。
当我尝试重新启动主管进程时,它会因 FATAL 错误而死:
找不到命令“gunicorn”
我做错了什么?如果我需要提供更多信息或背景,请告诉我。

【问题讨论】:
-
您使用的是 uwsgi conf 中的
http设置,这是不同的。只需指定一个端口 -
您在 supervisord conf 中有错字:
directory=/webapps/batch而不是directory=/webapps/patch -
@reptilicus 我尝试作为套接字 (
uwsgi --socket 127.0.0.1:3031 --wsgi-file views.py --master --processes 4 --threads 2),但http:\\server_ip_address:3031没有返回任何内容 -
@TomaszJakubRup 已修复,但这不是问题 - 在复制粘贴问题时发生
-
nginx 配置中的下一个错字:
server 127.0.0.1:8008 fail_timeout=0;而不是server 127.0.0.1:8080 fail_timeout=0;
