Question

我已按照以下教程设置了nginx + web2py + uwsgi，但nginx无法访问uwsgi套接字。下面是我的配置文件。当我打开localhost时，它显示502错误的网关，而nginx错误日志显示了尝试访问web2py.socket时被拒绝的权限

下面的命令用于运行uwsgi

exec /usr/local/bin/uwsgi --ini /etc/uwsgi/web2py.ini

Answer 1

您需要以同一用户运行 nginx 和 uwsgi 进程。另外，您可以更改套接字文件权限，但是由于安全问题，不建议您更改该权限。

解决方案1：

在您的 /usr/local/etc/nginx/nginx.conf 文件中将#user nobody;行更改为user _www;（以便在 _www 下运行Nginx进程用户）

然后重新启动Nginx服务

解决方案2：

在您的 /etc/uwsgi/web2py.ini 文件中将chmod-socket = 600行更改为chmod-socket = 666。 （不推荐）

然后重新启动uwsgi服务
