Hi!
I recently installed the varnish cache with my apache webserver on my ubuntu 18.04 VPS. I have varnish running on port 80 and apache on port 81(Docker is using 8080). It ran fine but now randomly shuts down every 5hrs or so. It gives the error
Code:
 caught SIGTERM, shutting down
. I then checked the syslog and got this.
Code:
Jun 25 18:43:02 vmi425722 systemd[1]: apache2.service: Main process exited, code=exited, status=1/FAILURE

Jun 25 18:43:02 vmi425722 systemd[1]: apache2.service: Failed with result 'exit-code'.


And:
Code:
[core:warn] [pid 32583] (101)Network is unreachable: AH00056: connect to listener on [::]:81.


And:
Code:
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80

.

This has only been happening since I installed varnish. I dont get why it cant connect to port 81, I have set it in ports.conf & have opened it in ufw. Does anyone know how to fix this? Or any advice?

Thanks,
Kian

Hi Kian,

did you change all the ports in all vhosts?

Also you have to change the "Listen 80", too, to Listen 81

Hi James,
Yep, all port are changed in all sites-available conf and my ports.conf now says Listen 81.
