      In order to update the user/group owner of the tomcat processes with the new systemd service unit on RHEL 7 users will need to update the User and/or Group properties of the service unit (/usr/lib/systemd/system/tomcat7.service and/or /usr/lib/systemd/system/tomcat8.service) rather than the sysconfig or tomcat conf files.

      In order to update the user/group owner of the tomcat processes with the new systemd service unit on RHEL 7 users will need to update the User and/or Group properties of the service unit (/usr/lib/systemd/system/tomcat7.service and/or /usr/lib/systemd/system/tomcat8.service) rather than the sysconfig or tomcat conf files.

      The following is an excerpt from /usr/share/tomcat8/conf/tomcat8.conf showing that TOMCAT_USER is configured there:

      # What user should run tomcat
TOMCAT_USER="tomcat"

      However, this is quite misinforming as updating TOMCAT_USER or TOMCAT_GROUP has no effect on the service. This is because the service unit (/usr/lib/systemd/system/tomcat8.service) explicitly configures the User/Group which owns the service:

      [Service]
...
User=tomcat
Group=tomcat
...

      This is done because using environment variables in the systemd unit does not work by design (they only work when used with ExecStart/ExecStop and a couple other directives, read more here).
