Question /tmp folder almost full

antonello

New Pleskian
Hi,
i have /tmp folder almost full in a centos 6.5 and plesk 12.5.30
is it safe to delete files in /tmp folder?
There are many files very old for example:

repo_transport_tmp_SDfvoij
or
php34jkfdnl4
or
timthumb_tmpimg_34fdfFR

I will appreciate every help
Thanks
Antonello
 
I have 25GB in /tmp ...

/tmp/systemd-private-11abca3d47fd4d4ca4c057d616636dd5-plesk-php72-fpm.service

Why is it so big and doesn't it clean automatically?
 
Thanks, but if any files are used?

Stop Plesk services:
# service psa stopall
Stop PHP-PFM:
# service plesk-php<version>-fpm stop
Just in case some stuff is still running:
# service postfix stop
# service dovecot stop
# service nginx stop
# service httpd stop (or # service apache2 stop)
# service mariadb stop (or # service mysqld stop)

Then remove the temp files, then in the opposite order:
# service mariadb start
# service httpd start
.

Stopping services is not necessary - with linux, you can delete files that are still open, and they will only really be removed from disk & the space recovered when the last access handle to the file is closed.
As files in /tmp, by definition, aren't guaranteed to be persistent, it should not break anything if you just remove everything. But to be safe, you can use the suggestion to use find with option -mtime +1 to get only files older than a day, and then let it remove them with -exec rm -rf {} \;. Note that if you don't understand how this works you probably shouldn't use it, as there is ample opportunity to introduce bugs that sooner or later do a rm -rf /, wiping your system.

Restarting the server automatically cleans the tmp directory.
