cpanel /tmp not mounted correctly centos server

Normally on new cpanel installed servers /tmp will be secured using /script/securetmp utility


On some cases, you can the /tmp are not be mounted correctly
Even if you do several reboots after cpanel installation.

Generally, this will not create any problems or make performance related issues.

But, mounting the /tmp properly will gives us peace 🙂 and on verifying the usage of the /tmp
Keeping free space on /tmp is essential to run your mysql and http(webserver) without generating errors.

Checking securetmp is enabled on boot

root@cpanel server [~]# chkconfig --list | grep secure
  securetmp      	0:off	1:off	2:off	3:on	4:on	5:on	6:off

The above results says that, securetmp is already enabled at boot time
On this case, The server may just need to be rebooted

Even after the reboot, the /tmp is not mounted separately. you can use “/scripts/securetmp” utility to do this job.

First you should remove the /usr/tmpDSK file

root@cpanel server [~]# rm -f /usr/tmpDSK

Then you need to make sure /tmp (the directory you have now is empty).
You can just move it to a new name.

root@cpanel server [~]# mv /tmp /tmp.bak

Then run

root@cpanel server [~]# /scripts/securetmp

and follow the prompts.

Now, You should have a /tmp partition,

root@cpanel server [~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda5        20G  6.3G   13G  34% /
tmpfs            16G  6.5M   16G   1% /dev/shm
/dev/sda1      1008M  174M  783M  19% /boot
/usr/tmpDSK     1.9G  423M  1.4G  23% /tmp

but I would try a simple reboot first whenever you get the chance to do so as it may fix the issue for you

Make sure, You do take backups if required before starting this. We test it on live and test servers before posting.
