Increase TMP on CentOS / WHM / CPanel

Closed - This job posting has been filled and work has been completed.

Job Description

I have a web server with 100 small websites on it. My TMP drive is maxed out and it's causing sites to not load, plus it's not allowing CPanel / WHM to upgrade to the latest version.

Cpanel won't upgrade because it's at 0,9gb and it needs 1.6gb. I've got a ton of space so I was thinking of making tmp into 5gb. Here's my config:

Filesystem Size Used Avail Use% Mounted on
/dev/sda5 7.8G 7.2G 178M 98% /
/dev/sda8 198G 30G 159G 16% /home
/dev/sda6 996M 42M 903M 5% /tmp
/dev/sda3 7.8G 6.3G 1.1G 86% /usr
/dev/sda2 9.7G 2.7G 6.5G 30% /var
/dev/sda1 122M 22M 95M 19% /boot
tmpfs 2.0G 0 2.0G 0% /dev/shm
/dev/sdb2 230G 96G 123G 44% /backup

I have CentOS, cpanel/whm

I'm assuming you can just do it with a sym link and the whole job should take less than an hour. Please give me a very high level of how you would tackle this problem in a way that won't risk my sites and data.

I found this tutorial but the file locations etc. don't look right:

I think there's a way to do it with Bind too but I'm really not a Linux guy.
