Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

So I was undoing some changes here on CentOs 6, and I ended up removing all users who had root access, accept for the root user. But then I realized the root login is disabled, and I just disabled root access for the user I am logged into.

Now I can't modify/access really any file.

What can I do from here? Through FTP it just blocks uploading.

Do you have physical access to PC? Are you using dm-crypt or any other data encryption? Can you change boot device? –  week Nov 8 '13 at 20:40
    
Actually its my VPS from VMBox.Co so I don't have any physical access.. Am I left to now just re install the entire server? –  Travis Nov 8 '13 at 20:41
    
Did you tried single user mode? –  week Nov 8 '13 at 20:43
    
I don't know how to exactly boot into single user mode, I connect through SSH using putty. –  Travis Nov 8 '13 at 20:45
    
You need to have access to terminal through some KVM solution. –  week Nov 8 '13 at 20:46

You may login as root by editing Grub configuration on system boot, manual @ centos.org and login in single user mode, then you simply change what you need.

OR

Use KVM (solution in this case) :)
