Re: [users@httpd] Graceful shutdown of apache

[Hemant Chaudhary <he...@gmail.com>]

Hi,

I have updated apache-2.4.29 to apache-2.4.37 but still I am not able to
graceful shutdown in debug mode.

Can you please tell me how should achieve it. ? or let me know the function
which I should call for proper graceful shutdown.

Thank you
Hemant

Each MPM (event, worker, process) has it's own signaling architecture
between parent and child processes.

The parent process signaling is documented here;
https://httpd.apache.org/docs/2.4/stopping.html

You will need to review the behavior of the child signal handler specific
to the MPM you want to control.

Quoting the doc above; "You will notice many httpd executables running on
your system, but you should not send signals to any of them except the
parent, whose pid is in the PidFile. That is to say you shouldn't ever need
to send signals to any process except the parent. There are four signals
that you can send the parent: TERM, USR1, HUP, andWINCH, which will be
described in a moment."

So what you seek to do is, effectively undocumented/unsupported. Debug mode
is not a supported operating mode, as I mentioned earlier.

What do you mean by a graceful shutdown? The graceful command doesn’t shutdown apache. If you are using graceful-stop then that will either stop apache or report an error.

Please provide some logs.
