How to change varnish port in Ubuntu
To change the varnish port, run the command
systemctl edit varnish
It opens an editor, in the editor, paste the following
[Service] ExecStart= ExecStart=/usr/sbin/varnishd -j unix,user=vcache -F -a :80 -T localhost:6082 -f /etc/varnish/default.vcl -S /etc/varnish/secret -s malloc,256m
This will change varnish listening port to 80. If you need to change to another port, change “-a :80” to whatever port you want to use. Save and exit the editot.
Now resart varnish
systemctl restart varnish
Back to Varnish
