You may have encountered the following issue trying to run “fuser” command on CentOS/RHEL 7 :
fuser: command not found
Many system administrators turn to do minimalist installation with version 7, unfortunately this even cut some critical basic components such as “traceroute, ifconfig, fuser, etc.” which in my opinion should be a part of a minimal install!
Anyway, you may have tried to install the command with Yum without success, because it is a part of a package named “psmisc“.
Simply use the following command to install fuser :
yum install psmisc
