Re: [Cppcms-users] Hello_world with Nginx 502 Bad Gateway

[Artyom B. <art...@ya...>]

Hello,


Ok I see...

This happens with newer versions of nginx.

The problem that some nginx options had changed and it does not
work as it was before.

1. You must start it as root (otherwise it would fail to write to logs)
2. Then it forks of to undefined user and can't open a socket that
   the cppcms application creates - as it runs as root.


So you have two options:

1. Use TCP/IP - instead of Unix domain sockets:
   switch "socket" : "/tmp/hello-fcgi-socket" to "port" : 9000
   so you will not have permission options.

2. Configure nginx manually such that it and the cppcms service run in
   same user:group instead of using cppcms_run.

   You can configure it instantly for some socket or TCP ip port
   and then run application as any other applications.

   ./hello.fcgi -c config.js

   And the web server connect it.
