Apache: how to remove old sessions from a custom directory

Question

PHP

Good evening.
There is a site whose session files are not in the default directory, but in a separate directory. This is specified via .htaccess
php_value session.save_path './../_sessions'
Files are saved to this directory. Only here's the trouble - the old sessions will not be deleted. The server config specifies a session lifetime of 10 minutes. But files from this directory are not deleted. Rights are enough.
I thought, maybe if it's a custom directory, then you need to delete it yourself? But something tells me it's wrong.
Tell me what could be the problem?

Answer 1

You won't believe it, but in a regular directory, session files are also deleted "by hand" +)

root@master:~# cat /etc/cron.d/php5 
# /etc/cron.d/php5: crontab fragment for php5
#  This purges session files older than X, where X is defined in seconds
#  as the largest value of session.gc_maxlifetime from all your php.ini
#  files, or 24 minutes if not defined.  See /usr/lib/php5/maxlifetime

# Look for and purge old sessions every 30 minutes
09,39 *     * * *     root   [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete

I prefer something like this:

[email protected]:~# cat /usr/bin/clear_sess.sh 
#!/bin/bash
/usr/bin/find /var/lib/php52 -mmin  +XXX -delete -print
# где XXX - количество минут (правда, у меня в днях mtime).

And then I run it in the cron via flock:
flock -n /tmp/clear-sess.lock -c /usr/bin/clear-sess.sh

If possible, it is better to transfer the storage of sessions to memcash.
