Issue/Introduction
How to create a systemd service for a DUAS node on RHEL9 and other Linux distributions that don't accept the sysv script delivered currently in the product (7.00.21 and inferior).
Environment
DUAS 6.x and 7.x
Resolution
This is the procedure to create a systemd service for starting a DUAS node. First, you need to login to the server as the root user and then follow these steps:
There are 2 ways of doing this, the first one has been tested more elaborately:
First method:
Create a start script called: <du_rootdir>/unistart_<du_company>_<du_node>.sh containing:
#!/bin/sh
rc_script=0
. <du_rootdir>/<du_company>_<du_node>/unienv.ksh
<du_rootdir>/<du_company>_<du_node>/bin/unistart
rc_script=$?
exit $rc_script
Create a stop script called <du_rootdir>/unistop_<du_company>_<du_node>.sh containing:
#!/bin/sh
rc_script=0
. <du_rootdir>/<du_company>_<du_node>/unienv.ksh
<du_rootdir>/<du_company>_<du_node>/bin/unistop
rc_script=$?
exit $rc_script
Create the systemd script called /etc/systemd/system/DUAS_<du_company>_<du_node>.service containing:
[Unit]
Description=DUAS Daemon (<du_company>_<du_node>)
After=syslog.target network.target
[Service]
Type=forking
WorkingDirectory=<du_rootdir>
ExecStart=<du_rootdir>/unistart_<du_company>_<du_node>.sh
ExecStop=<du_rootdir>/unistop_<du_company>_<du_node>.sh
User=univa
[Install]
WantedBy=multi-user.target
Now install the script with the commands:
systemctl daemon-reload
systemctl enable DUAS_<du_company>_<du_node>.service
+++
Second method:
Create the systemd script called /etc/systemd/system/DUAS_<du_company>_<du_node>.service containing:
[Unit]
Description=DUAS Daemon (<du_company>_<du_node>)
After=syslog.target network.target
[Service]
Type=forking
WorkingDirectory=<du_rootdir>
ExecStart=/bin/sh -c 'source <du_rootdir>/unienv.ksh && <du_rootdir>/bin/unistart'
ExecStop=/bin/sh -c 'source <du_rootdir>/unienv.ksh' && <du_rootdir>/bin/unistop'
User=univa
[Install]
WantedBy=multi-user.target
Now install the script with the commands:
systemctl daemon-reload
systemctl enable DUAS_<du_company>_<du_node>.service
+++
Stopping and starting
After rebooting the server the DUAS node will now start automatically or you can stop/start the node with the command:
systemctl stop|start DUAS_<du_company>_<du_node>.service
