[SOLVED] Add user to Sudoers File?

[AgentTeddie]

How do I add myself to the Sudoers File? When I go to use the "Sudo" command, it tells me I am not in the Sudoers File, so I have to do "su -" to bypass it for the time being. How do I add myself? Thanks

Sudoers file is located in /etc/sudoers. It should have examples inside of what you need to add.

I do not have an /etc/sudoers file, I have an /etc/sudoers.d file and when I open it it says that it can not open the file. What do I do?

Run:

 su -c visudo

Enter your password then scroll down to the line that says:

## Allow root to run any commands anywhere
root            ALL=(ALL)       ALL

Add the following line directly after the above, where "username" is your user name:

username          ALL=(ALL)      ALL

Scroll down to the following line

## Allows people in group wheel to run all commands
# %wheel ALL=(ALL)       ALL

Remove the # in front of the second line

That's how I did it, anyway. I actually didn't need to the last part for it to work, so I'm not sure what it does. It's just how I learned to do it when I first got started.

use

su
passwrd
#visudo

it will open the file /etc/sudoers
then
copy the line with yy command
root ALL=(ALL) ALL
and rename it to
"username u want to add" ALL=(ALL) ALL
save the file
now u r in sudo

FedoraPlus does it for you too.

I did this but how do I save it? I cannot figure out how to get out of it?

You can save and exit the file by pressing "esc" to get into command mode (after making the necessary changes to the file) and then type ":wq" which Writes to disk and Quits.

That for me does not work, I hit ESC and it does nothing...

SO how do I save because when I hit ESC nothing happens, it will not let me type?

Please share your knowledge so people who are having same problems and have found this thread can solve their problems as well.

As root type echo 'username ALL=(ALL) ALL' >> /etc/sudoers. Obviously substitute username for your username

"easy" method is to use an alternate editor.

visudo is preferred as it (visudo) checks for syntax errors. Not as critical on Fedora as on Ubuntu as the root account is not locked.

1. become root

su -

2. Set your editor

export EDITOR=nano

If you do not like nano, use another tool, gedit, kate, leafpad, etc.

3. Edit away

visudo

Also, FYI, when editing your sudoers file, keep in mind the "last match" for your user (often) takes precidence.

So, I would advise you use:

username ALL=(ALL) ALL

on a single user system, or

%wheel ALL=(ALL) ALL

on a multi user system where you want to grant root privileges to a group of users, but not both.

PLEASE NOTE: this command no longer works, at least not on a clean install of FC 17. It *did* work using the live disc, which is odd. But on an install, nope.

The notes in the sudoers file read:

This file must be edited with the 'visudo' command.

This means echo doesn't work, and you can't open sudoers with gedit. Apparently visudo checks the syntax of any changes before saving, and won't allow you to save if it's wrong.

So scratch that old trick off your list. It's been deprecated. Now, all you have to do to add your user name to /etc/sudoers is...

-switch to root
-run visudo
-figure out how the hell to use visudo, which is as easy as learning to use vi

Easy!

visudo uses the default editor--for example, on Ubuntu, I think it will open with nano.

If you prefer nano you could probably use

su 
EDITOR=nano
visudo
