Sometimes, our applications needs more temporary storage, in our server.

This article shows how to increase the /tmp partition, in Linux Server.

1. Stop MySQL and Apache services

# /etc/init.d/mysql stop
# /etc/init.d/apache2 stop

2. Run

# df -h

3. If /tmp mount point exists

# cp -rp /tmp /tmp.bak

4. Create an empty file within /usr/temp-disk

# dd if=/dev/zero of=/usr/temp-disk bs=2M count=1024

5. Apply FS to the new file

# mke2fs -j /usr/temp-disk

6. If /tmp mount point exists

# umount /tmp

7. mount the FS in /tmp and apply the correct permissions

# mount -t ext3 -o rw,noexec,nosuid,loop /usr/temp-disk /tmp
# chmod 1777 /tmp

8. Check if the OS assumes the mount point

# mount

9. Edit FSTAB and apply the new TMP

# vim /etc/fstab

Insert at the end of the file:

/usr/temp-disk /tmp ext3 rw,noexec,nosuid,loop 0 0
