Question Change Apache Port

[Krooms]

Server operating system version

Ubuntu 24.04

Plesk version and microupdate number

18.0.71

Hello,

I want to use Caddy or Traefik as reverse proxy, so I want to change the listen ports for Apache from 80/443 to 8080/4443.
I already tried editing the ports.conf to

Listen 8080

<IfModule ssl_module>
        Listen 4443
</IfModule>

<IfModule mod_gnutls.c>
        Listen 4443
</IfModule>

and the 000-default.conf to

<VirtualHost *:8080>

In Caddy I set a reverse proxy for the website domain to server-ip:4443 and tried server-ip:8080, also.

In both cases I see the default Apache2 page, when I visit the domain, but editing the index.html in Plesk has no effect.

Setting the reverse proxy to :4443 allows me to get a Let's encrypt certificate for the domain, setting it to :8080 gets me a failure while obtaining a certificate.

When I open the httpd.conf (#/var/www/vhosts/system/domain/conf/)for my website I can see that still port 443 and 80 are in use.

<VirtualHost IP:443 >
.
.
.
<VirtualHost IP:80 >

In the httpd.conf it is written that I should not modify this file and instead modify those two files:

#/var/www/vhosts/system/domain/conf/vhost.conf
#/var/www/vhosts/system/domain/conf/vhost_ssl.conf

But those two files do not exist.

Any help would be appreciated. I'm totally new to this and it took me days to figure this all out.

This setup is not supported out of the box.

You can use nginx on ports 80 and 443. Proxy the requests to your desired Caddy or Traefik then proxy to Apace on 7080/7081.
With this option, Plesk will handle the SSL certificates for you.
You can also set Apace to listen on localhost thus the Caddy/Traefik rules don't have to use your public IP.

Another approach, I don't recommend, is using a custom template.

You can change the Apache2 Port in the "ServiceNodeConfiguration" table of the "psa" database.
After that you need to rebuild all webserver configuration files and should be good to go. (you can use the Configurations Troubleshooter extension for that)

But just so I've mentioned it, this is completely unsupported by Plesk, so do at your own risk.
There is a chance, that a Plesk upgrade may reset/revert that configuration again.

So the easiest and safest way is to use nginx as proxy?

Installing the nginx package via plesk will reconfigure apache to use ports 7080/7081?

Yes.
