nGinx Port change for Varnish cache

[ikhan05]

Hello,

I have installed varnish cache server 6 today, my current configuration is nGinx Front on port 80 and Apache behin on port 81 and ssl 444 as WHM default settings. but i want Varnish act as Front Cache so i change the port of nGinx server from this file /etc/nginx/conf.d/default.conf

port 80 to 82
ssl 443 to 445 as i want both http and https listen via varnish.

to

server {
    listen 82;
    listen [::]:82;

    # We want SSL for this server so http:// and https:// work the same for these server_name’s
    listen 445 ssl;
    listen [::]:445 ssl;

after this i change the Varnish configuration file to listen nGinx as this is in the middle between apache and varnish so i change the followin in

/etc/varnish/default.vcl

# Default backend definition. Set this to point to your content server.

backend default {

    .host = "127.0.0.1";

    .port = "82";

and in /lib/systemd/system/varnish.service

ExecStart=/usr/sbin/varnishd \
      -a :80 \
      -a :8443,PROXY \
      -p feature=+http2 \
      -f /etc/varnish/default.vcl \
      -s malloc,256m
ExecReload=/usr/sbin/varnishreload

with thin configuration APACHE AND VARNISH is UP and RUNNING but the nGinx is not start and it keep shows the 80 port bind error:

as i already updated the port in the nginx configuration file at /etc/nginx/conf.d/default.conf but it still not listening this, is there any other file i have to update ? as i believe whm/cpanel generate its own configuration ? any help would be appreciated.

Thanks

Hello! While we do not support the configuration of Varnish, the following article helps explain where our nginx configurations would be. I hope this helps.

Hello Anthony,

I m not asking varnish support, i am here to ask you to which file is nGinx listen ? because the file is mention on your provided article already modified to listen on port 82 but it wont listen 82 port in this file /etc/nginx/conf.d/default.conf

Have you found a workaround for this? Could you share it with me?
