Very Computer

Hello.

I have a server configured with about 30 seperate domains and all of which run their own httpd deamon.
It seems I have to reboot every two days to keep the system from slowing down.  Is there any documentation
on setting up a server this way or does anyone have any advice on how I can keep the server from slowing
down so much?

Any advice would be appreciated.  Thank you.

Hello Robert,

  you may just be able to get away with causing the WebServer to 'hangup';
that is, to 'restart' itself.

I use this trick to get automatic logfile archiving. What you need to do
is to set up a cron job that will call a script which cause the WebServer
to 'hangup'.

Note :- I'm using the most groovy NCSA 151 WebServer

The Perl script I use (a stripped version anyway) does this:

    #!/bin/perl

    # Get the process ID of the 'parent' WebServer. There's probably a more
    # 'elogant' way of doing this!
    open(FOO,'/info/www/logs/httpd.pid');

    close(FOO);

    # Return the process ID of the 'parent' WebServer.
    $pid=$lines[0];

    # Restart the WebServer.
    system('kill','-HUP',"$pid");

The only bit you'll need to change is the line:

    open(FOO,'/info/www/logs/httpd.pid');

so, that this script accesses the 'PidFile' set in the WebServer's
configuration.

Hope this helps,

Steff

Steff> doing this!  open(FOO,'/info/www/logs/httpd.pid');

Well, I think there is a more elegant way: there's no need
to read in the whole file (even though it is likely to be
just one line).

if (open(PID, "/path/to/pid/file")) {
    chomp($pid = <PID>);
    close PID;
    ...

Steff> system('kill','-HUP',"$pid");

`kill' is a perl builtin, viz.

    kill HUP => $pid;

or

    kill('HUP', $pid);

(see `perlipc' manpage)
