Starting IRIS as a service on CentOS7 startup ( autostart )
If you want to start IRIS as a service on CentOS7 you can use systemd.
Login as root and create a new file iris.service in /etc/systemd/system.
# vi /etc/systemd/system/iris.service
[Unit] Description=Intersystem IRIS Service After=network.target [Service] Type=forking WorkingDirectory=<iris-install-dir> User=root ExecStart=<iris-inst-dir>/bin/iris start "<instance>" ExecStop=<iris-inst-dir>/bin/iris stop "<instance>" quietly Restart=on-abort [Install] WantedBy=default.target
<iris-install-dir> = Directory where you installed IRIS on Centos7 i.e. /iris
<instance> = The IRIS instance you want to manage.
After creating the file set the correct permission
# chmod 664 /etc/systemd/system/iris.service
Reload all Unit files of the service
# systemctl daemon-reload
Finally start the service ( if IRIS was already started then stop it )
# systemctl start iris.service
or
# systemctl stop iris.service
If everything works fine you can enable the service at startup:
# systemctl enable iris.service
Hope this helps.
