Question

Accidentally removed myself from sudoers list - how to fix?

I have accidentally removed myself from the sudoers list on my Centos 6 droplet. Root login is disabled, and I can still log in as myself (using putty and SSH), but cannot edit the sudoers file. Any ideas on how to fix this?

Thx, Arnold

Is root login only disabled via SSH? If so just use su.

@gparent … worked like a charm

If ‘su’ doesn’t work, you can reset your root password by logging into your account selecting your droplet then going to the access page on the left side, from there you can select reset root password and a new one will be emailed to you.

Most of us have been there at some point ;)

Select your droplet power it down and then “Kernel” look for “mount recovery kernel”.

Select that and power it back up

Connect to the console. that will give you root access to run the following command to add your user back into the sudo users group:

usermod -aG sudo <put-your-username-here>

Power it down, then go back to your original kernel and power it back up.

Log in and try to use sudo.

Thinks should be back to normal.
