Regards to all, I installed the varnish on my Ubuntu 20.04 server. On which Magento2 and Apache web services work. When I apply the varnish according to instructions, it will not work. Can anyone help. Thanks in advance everyone!
I notice that your varnish.service file is owned by vcache and has rw-r--r-- permissions.
I advise you to perform chown root:root varnish.service, because I'm assuming systemd doesn't have the right permissions to open the file.
Please also verify that the service files are hosted inside /etc/systemd/sytem, because one of your screenshots indicates that some of these files are stored in /etc/systemd.
Long story short, systemd will try to start services using the
rootuser. Make sure this user has read and execute permissions to access this file.
