[SOLVED] Cannot become root

nipunreddevil · Post by **nipunreddevil** » 2011/10/26 07:00:00

I just recently installed CentOs 6

A simple sudo or su doesn't work for me
Here is the exact trace

[nipun@dhcppc0 ~]$ sudo su
[sudo] password for nipun:
nipun is not in the sudoers file. This incident will be reported.
[nipun@dhcppc0 ~]$

I "nipun" am as such the only user.I tried running visudo which gave me the following trace
[nipun@dhcppc0 ~]$ visudo
visudo: /etc/sudoers: Permission denied
visudo: /etc/sudoers: Permission denied
[nipun@dhcppc0 ~]$

Catch22. You have to be root to run visudo. You have to be in /etc/sudoers before you can sudo. To fix this you will need to know the root password and use

[code]
su -
visudo
<now add yourself to the sudoers list and save it>
[/code]

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature. I presume from your thanks that the thread can be marked [SOLVED] for posterity, so I am doing so on your behalf.

Tried this:

"permission denied"

Tried booting from livecd, mounting:

sudo mount /dev/sda1 /mnt

then

sudo visudo -f /etc/sudoer

didn't find file

booted into CentOS (6.2)

there's a

/usr/bin/sudo (with an X through it - need root access)

and a

/etc/sudoers.d (same thing as above - need root access)

I understand need root access to GET root access.

Thought I had it, set it up and was using it.

Seem to have lost it. Need it back.

One more detail:

user is: home-pc

Anyone?
