The RedHat 7 handles the scripts differently after a reboot, so PatrolAgent.service has to be created.
Note:
RHEL 7 onwards uses systemd to start the services on their RedHat 7 server.
Below script file is a sample. User and path to ExecStart, ExecStop, ExecReload are to be updated as required
The below solution/script provided waits for the Centrify service to start, it can be updated as required.

1.Create a PatrolAgent.service script in the /tmp directory
 

[Unit]
Description=BMC Patrol Agent
After=network.target syslog.target local-fs.target centrifydc.service


[Service]
Type=forking
User=ssTruesightSvc
ExecStart=/appsHome/bmc/Patrol3/scripts.d/S50PatrolAgent.sh start
ExecStop=/appsHome/bmc/Patrol3/scripts.d/S50PatrolAgent.sh stop
ExecReload=/appsHome/bmc/Patrol3/scripts.d/S50PatrolAgent.sh stop;/ appsHome/bmc/Patrol3/scripts.d/S50PatrolAgent.sh start
KillMode=/appsHome/bmc/Patrol3/scripts.d/S50PatrolAgent.sh stop
Restart=no

[Install]
WantedBy=multi-user.target

2.After the script is created enter the below command

chmod +x PatrolAgent.service

3.Copy the PatrolAgent.service script from the /tmp directory to the /etc/systemd/sytem directory

4.Reload the systemd process to consider newly created PatrolAgent.service OR every time when PatrolAgent.service gets modified. Enter the below command:

systemctl daemon-reload

5.Enable this service to start after reboot automatically.

systemctl  enable PatrolAgent.service

6.If the PATROL Agent is running then kill the process and restart the service by entering the below command:

systemctl  start PatrolAgent.service
