Hi.
Sorry for the long post but I've been trying the whole afternoon :)
I have read the forums but cannot seem to find an answer to my question. I have a MailInABoxServer in my DMZ. I have setup port forwarding rules and everything is working perfectly! I have www.mydomain.com working. I now would like to add a Wordpress server for my blog at blog.mydomian.com. The mailinabox server is at 192.168.100.1 and the Wordpress machine at 192.168.100.2.
I therefore added the os-nginx plugin and can configure it without any problems. I used this how to https://wiki.opnsense.org/manual/how-tos/nginx.html to configure. I tried to configure but have a couple of questions:
1. I added an upstream server -> do I need to add one per port (you need to add the port on the config document)
2. I created the upstream, one per server
3. I created one location for www.mydomain.com and one for blog.mydomain.com. What do I enter for the Match Type, I have been using Exact Match ("="), correct?
4. I then created one server for www and added the www location document to it and one server for the blog and added the blog location to it.
When I deactivate the port forward rules I do not see my sites and get the following error in Logs/Global Error Log => invalid PID number "" in "/var/run/nginx.pid"
No matter what I do I cannot seem to start nginx (did this via the command line):
/usr/local/etc/rc.d/nginx: WARNING: failed to start nginx
root@firewall:~ # sudo service nginx start
Performing sanity check on nginx configuration:

does anybody have any tips for me?
Thx
-
oh, I did press the small and the large reload buttons multiple times ;D
-
Shooting from the hip, it's trying to bind to port 80 and can't. Something is already running on port 80, WebGUI maybe?
-
Thank you for your reply. I did have the webGUI @ 80, moved it to 8080 and restarted but am still getting the same errors unfortunately. Any other ideas?
-
run sockstat to find out which process has the port.
-
as far as I can see nothing @ port 80. funnily enough I installed 16GB of memory today which meant I needed to reboot - now I can start and stop nginx -> weird
here is the output

I'll check the nginx config at the weekend and will report back here!
-
I still seem to have a problem with my setup -> what I have noticed is that if I tick the "enable nginx" on the general settings page I cannot start nginx -> if it is not enabled I can start nginx on the dashboard? I have deleted all my settings, removed the nginx plugin and reinstalled. didn't help unfortunately 🙁
-
there is one thing how you could theoretically produce the error in nginx itself: bind a http server and a stream server to the same port (will never work).
-
Did you ever figure this out? I am trying to find a step by step reverse proxy guide for opnsense using nginx but I can't seem to make sense of the one in the documentation (it doesn't seem like it's complete or maybe its just because there aren't any examples), or if I did manage to follow it correctly, its not working.
-
Nope, never got this to work. I am giving it another try this weekend - if I get it working I'll report back here :)
-
If you can, please have a look at /usr/local/etc/nginx/nginx.conf for possible error causes.
