I have a system composed of about 15 services. They have no inter-dependencies (i.e. no service require another to start) and they notify systemd when there start-up is finished (i.e.
The problem is that if I start them all at the same time my system is overloaded and processes are killed due to systemd timeout.
What I want to do is "group" my services so they start one after the other is no particular order. Is this possible with systemd service file?
BTW: here is a template of my service file:
[Unit] Description=Template service file After=network.target [Service] Type=notify User=1000 Group=1000 # Set the working directory and the binary to start WorkingDirectory=/home/user/ ExecStart=/path/to/some/process # The standard input and output are useless (i.e. unused by the process) StandardInput=null StandardOutput=null # Disable the standard error because all logs are already saved in a specific directory StandardError=null # Send SIGTERM then SIGKILL after TimeoutStopSec seconds (default: 2) KillMode=mixed TimeoutStopSec=2 # Setup a start timeout TimeoutStartSec=30 # On abnormal (i.e. non 0 exit code or killed by a signal) termination restart the process after RestartSec seconds (default: 5) Restart=on-failure RestartSec=5 # Authorise process restart only 5 times maximum in a 120 seconds interval StartLimitBurst=5 StartLimitInterval=120 # Set watchdog timeout (default: 10) WatchdogSec=10 NotifyAccess=main # Set security options NoNewPrivileges=yes [Install] WantedBy=custom.target
Thank you for your help
