RE: [webmin-l] Rotating webmin logs

[Larry G. <Li...@IS...>]

Hi Neil,

I am running Red Hat and added a file to /etc/logrotate.d/ called webmin.
The file has the following contents:

/var/webmin/miniserv.error /var/webmin/miniserv.log /var/webmin/webmin.log {
    missingok
    notifempty
    sharedscripts
    postrotate
	/bin/kill -HUP `cat /var/webmin/miniserv.pid 2>/dev/null` 2>
/dev/null || true
    endscript
}

It is the same contents as httpd logrotate.

I believe the answer is yes.  Some time ago I asked a similar question and
the response was to mirror the httpd logrotate configuration.  My memory is
a bit rusty as to why apache needs to be restarted.  What I believe is
correct is that Apache will open a file and refer to the file by id an not
by name.  So when logrotate changes the filename, httpd needs to be
restarted to find the new id associated with the new name (i.e. access_log)
versus the renamed file (i.e. access_log.1).  Otherwise you would continue
to keep logging to the renamed file.  So in short, I believe that Apache and
Webmin open a file and keep it open to stream log events rather than
opening, writing, closing, opening, writing, etc.  A restart is necessary to
close the file and open the new log.

Any corrections are most welcome!

Larry:

Does webmin need to restart each time the log rotates?

Thanks,
