The systemd service for the jar file receives an error "run time" after a few minutes or remains in "activation mode",

service unit:

[Unit] Description=test After=syslog.target After=network.target [Service] Type=forking ExecStart=/bin/java -jar /home/ec2-user/test.jar TimeoutSec=300 [Install] WantedBy=multi-user.target

it starts with a penalty for 1-4 minutes. But then he fails:

tail / var / log / messages:

systemctl status test.service (upon restart, in activation mode):

systemctl status test.service (after failure):

  • when running jar on the command line it works fine.
  • tried to change the location of the jar because I thought it was a permission issue.
  • selinux is off

How can I fix this problem to start the jar on boot? are there any alternatives? (RHEL7 does not include a service command)

You have done the forking service forking , but this service is not a fork. It just works directly. Thus, systemd waited five minutes for the program to dismantle itself, and it never did. The correct type of service is simple .

You have also disabled SELinux, which is another issue that you must solve.
