Hello,

Apache version: Apache/2.4.25
PHP version: 7.1.4

[root@server /]# service varnish restart
varnish: unrecognized service

This is the situation. But there is no varnish file in the middle. What could be the problem?

I have added version 3 of varnish repo. But the server is doing load. A new update is a must. Please develop a solution

looks like varnish is not getting installed or generating some errors during the build.  check the install log file.

looks like you have some issues with yum or conflicts,try checking logs more detailed and test yum install.

I'm sorry to be late, I've reinstalled the server and it works fine.
