title: How to free up space on centos server
body: <p>I'm getting daily warning that my VPS server space is getting full. I have deleted old kernals, cleaned up install files and reduced the amount of backup stored. I'm not really sure what else I can delete?</p>
  
  <p>I run the command:</p>
  
  <pre><code>du --max-depth=1 -h /
  
  0       /dev
  16K     /lost+found
  1.6G    /var
  75M     /opt
  89M     /run
  2.8G    /backup
  38M     /etc
  4.0K    /cd
  4.0K    /srv
  4.0K    /media
  7.4G    /usr
  2.6M    /tmp
  0       /sys
  179M    /boot
  61M     /root
  4.0K    /mnt
  149G    /home
  </code></pre>
  
  <p>I also run the command:</p>
  
  <pre><code>df -l

  <p>I have about 10 websites running on this VPS and I also deleted any backups stored within their respective accounts. Is there anything else here I can get rid of that I don't need? </p>
