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
