postrotate in logrotate

Hi All,

I am a newbie to linux and working on RHEL. I tried to implement logrotation for apache logs and stuck at restarting a process after apache restart.My script is as below

/usr/local/apache2/access_log {
weekly
rotate 25
compress
create
postrotate
/usr/local/apache2/bin/apachectl restart > /dev/null 2>&1
if [ -f /usr/local/apache2/logs/httpd.pid ];then
sudo -u reto ./usr/local/Misc/Start_Stream.sh > /dev/null 2>&1
fi
endscript
}
when i execute this script with root user, Apache is getting started but the script in the condition which has to be run with reto user is not executing..Any inputs please.
Thanks in Advance.

Here's one that does work:

Code:

/var/log/httpd/*_log {

  rotate 10

  notifempty

  missingok

  size=5M

  compress

  delaycompress

  sharedscripts

  postrotate

    /etc/rc.d/rc.httpd restart

  endscript

}

For your purposes, you'd edit the log location to

Code:

/usr/local/apache2/access_log {

(possibly changing "access_log" to "*_log" to catch both the access_log and error_log).

You would edit the /etc/rc.d/rc.httpd restart to your system's actual start up program (the one that executes at boot) if it includes the restart directive, or simply to edit the apachectl line, adding the -k option:

Code:

/usr/local/apache2/bin/apachectl -k restart > /dev/null 2>&1

You most likely do not need

Code:

if [ -f /usr/local/apache2/logs/httpd.pid ];then

sudo -u reto ./usr/local/Misc/Start_Stream.sh > /dev/null 2>&1

fi

If you have a special purpose for those, leave them in place but do the following.

See Stopping and Restarting at http://httpd.apache.org/docs/2.2/stopping.html; essentially, the -k option sends a TERM signal to the running process causing it to kill off all of its children. Can't hurt, might help.

You might also want to change the size=5M (which is a test for the log size being 5 megabytes) to some other value depending upon how large your logs get in a week.

Hope this helps some.

logrotate like cron really requires full/absolute paths to ensure stuff will run

Code:

sudo -u reto ./usr/local/Misc/Start_Stream.sh > /dev/null 2>&1
