Righto, so it looks like the Sudoers file, that I need to edit, is read only.
However, I have found what looks like a good set of instructions here: https://www.digitalocean.com/community/tutorials/how-to-edit-the-sudoers-file-on-ubuntu-and-centos
EDIT: This initial setup guide has a slightly different (I think) way of doing it (step 4) https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-12-04

Hmmm, perhaps editing the Sudoers file is not a good idea...
Should I edit the file and add my username or just use su?
Comments @JaredBusch, @thecreativeone91, @scottalanmiller or @thanksajdotcom ?
EDIT: I'll hold off on deploying this for now.

I log in as root directly to all my servers.

You don't edit the file You'd gpasswd -a nadnerb wheel where nadnerb is the username you wish to give sudo privileges too.

I personally would disable root access over SSH after the initial setup.

Thanks for your input but I won't be doing this

Fantastic! Thanks!

On the secret To-Do list

No Problem. It's just a group you add it to, as the group has sudo premissions (sudoers file) .

Why?

Just means you have to tell the editor that you "mean it" when you save. In vi that means :w! instead of :w

nadnerB

Righto, I've blocked root access via SSH and renamed the server to something more useful (for ron... later on)

Hmmm, attempting to install htop is proving to be more difficult than yum -y install htop.
I can't seem to connect to any of the mirrors.
*http://mirror.netflash.net/centos/7.0.1406/updates/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not *resolve host: mirror.netflash.net; Unknown error"
Trying other mirror.

scottalanmiller

Often that means that DNS isn't set up. Can you lookup addresses in general?

You might need to set dns in resolv.conf

coliver

If the DNS issue doesn't resolve it you may have to refresh your YUM cache. I think a yum -clean all or yum -clean headers will do that.

nadnerB

Excellent suggestions! I'll check that out when I get home

nadnerB

Found the location of resolv.conf and how to edit here: http://ask.xmodulo.com/configure-static-dns-centos-fedora.html
htop now installed. I quite like it

scottalanmiller

All configuration is just in /etc

nadnerB

@scottalanmiller nice. I screen shot the directory from my laptop with a GUI

EDIT: that sounded disturbingly like TV IT. I apologise to all those who are racing for the spew buckets
