cronjob for php-session

Hello all,

I want session files older than 30 minutes automatic deleted and according to this information found in php.in I have to create cronjob or a script

Code:

; NOTE: If you are using the subdirectory option for storing session files
;       (see session.save_path above), then garbage collection does *not*
;       happen automatically.  You will need to do your own garbage
;       collection through a shell script, cron entry, or some other method.
;       For example, the following script would is the equivalent of
;       setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          cd /path/to/sessions; find -cmin +24 | xargs rm

My path to session is /var/lib/php/session so I tried the following possibilities:
[root@obelix ~]# crontab -e

Code:

*/30 * * * * root find -cmin +30 | xargs rm /var/lib/php/session &> /dev/null

Code:

*/30 * * * * root /var/lib/php/session find -cmin +30 | xargs rm /var/lib/php/session  &> /dev/null

Code:

*/30 * * * * cd /var/lib/php/session find -cmin +30 | xargs rm &> /dev/null

None of them work.

Who knows the right syntax ?

 

Take a look at http://www.howtoforge.com/back_up_mysql_dbs_without_interruptions

The /usr/local/sbin/mysqlbackup.sh script should give you the idea how to do this.

 

My php set up has this cron job to delete sessions every 30 minutes. In /etc/cron.d/php5 file...

Code:

0,30 * * * * root [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -print0 | xargs -n 200 -r -0 rm 

You may want to change php5 to php in your setup.

 

@ Falko,

At first I thought "stop this is too difficult for me" my second thought was "a challenge"

What you say is make a script and make a cronjob for the script.
From your example I only need

Code:

#!/bin/sh

datum=`/bin/date +%Y%m%d-%H`

for file in "$( /usr/bin/find /home/sqlbackup -type f -mtime +2 )"
do
  /bin/rm -f $file
done

exit 0

and adjust this

Code:

"$( /usr/bin/find /home/sqlbackup -type f -mtime +2 )"
do
  /bin/rm -f $file

to

Code:

"$( /usr/bin/find  /var/lib/php/session -type f -cmin +30 )"
do
  /bin/rm -f $file

Code:

chmod 755 /usr/local/sbin/cleanup.sh

Finaly I create the cronjob

Code:

*/30 * * * * /usr/local/sbin/cleanup.sh &> /dev/null

I will give this a try.

@BorderAmigos,

I am challenged by Falko's suggestion, if I fail I use your cronjob.
