How to stop systemd service stack overflow in Linux?
In this case I had to kill with PID. You need to put in a ExecStop option in the [Service] section with the command you want to use to stop the service. Then you can stop the service with systemctl stop flume-ng.
Is it easy to set up socket in systemd?
For the fly-by programmer, sockets can be somewhat hard to get right, but by using systemd’s socket units, you can make systemd do the heavy lifting. Besides making sockets simpler to set up, systemd dumps whatever comes in through the socket to STDIN.
How to see when a systemd service was started?
If you need to script this, you should look into using the systemctl show command. It is more useful for scripts than trying to parse anything from status. For example, to find when the service last started you can use: If you would like to see all the properties available just omit the flag and it will dump them all out.
Why does systemd dump socket data to stdin?
Besides making sockets simpler to set up, systemd dumps whatever comes in through the socket to STDIN. This means you don’t have to bother with complicated socket management in you script; just pick up the data from STDIN and use it from there.
When to use execstop and deactivate in systemd?
Such systemd units will wait until the process specified by ExecStart terminates, and then deactivate by running the process specified by ExecStop. Type=simple (the default setting) is used when the process configured with ExecStart is the main process of the service.
What happens if there is no execstop command?
The process specified by ExecStop will run in case the service crashes. In the absence of any ExecStop option, the systemctl stop servicename command will simply kill the remaining processes of the unit, as specified by the KillMode option.
What does systemd do when a process doesn’t terminate?
If the process doesn’t terminate, then systemd sends SIGKILL signal which does the job. If the main process has forked off other processes, systemd will take them down too since they all live in the same cgroup.
