How to run n2o on 80 port?

I've tried changing port both in wf_core.erl and sys.config, but now it can't even initialize webserver.

Checked if something is using 80 port - it is free.

Solution

  • You should install authbind in case you need running 80 port. Create file 

    /etc/authbind/byport/80

    and set rwx access to user you need run under. Then perform 

    authbind --deep ./start.sh

    P.S. you need to specify port only in sys.config. In web_sup you should use 

    wf:config(port)

    Like in https://github.com/synrc/n2o_sample/blob/master/src/web_sup.erl#L17

    You shouldn't touch wf_core, it's default port is 8000 and it is use port from config.
