Hello there,

Can anyone tell me how can iI give root privilegis to a user because I want to install oracle and it says that I don't have to do it like root but also I have to install php with oracle and apxs and I need to do that as root

Thank's

I would use sudo as it will all you to give root privileges without giving out the root password.

But I don't want to became root I jast want to remain a user but with root rights. Is there any command that as root I can give to a user root's wrights

This is what sudo does. If you type "sudo ls" you will remain you, but the ls command will be executed as root. You can specify what users can execute what commands in the config file.

Is there something wrong with my linux because he doesn't know the sudo command? It says that command not found .

I have installed RedHat6.2

The sudo binary is usually in /usr/bin. It may not have been installed by default. You can download sudo from http://www.courtesan.com/sudo/.

If you 'wish to make a user permanently root equivalent, like I did with my Admin account. You have to do a sort of hack.
Here's the steps to do it:
1. Log in as root
2. edit your /etc/passwd file with an editor
3. search for the loginname of your user
4. you will find a line like this:
admin:x:501:501:admin:/home/admin:/bin/bash
1 2 3 4 5 6 7
5. Don't worry if the numbers after the X are different
This is what they mean:
1= Loginname
2= Encrypted password, here it is a shadowpassword
3= The User ID
4= The Group ID
5= The name of the user
6= The homedirectory of the user
7= The login shell of the user
6. All you have to do now, is to change both the user and the group ID to 0 which means the User ID = ROOT and group ID = ROOT
7. Now login as the new user and you have root equivalency.

One minor problem is that from now you will receive all the mail that the root user receives also. You share one emailbox, that is the ROOT email.

The root user is a superuser and you should never create an equivalent account. Its a gross security violation and a very poor safety practice. I know all the excuses people give for doing it.. but sooner or later.. you WILL get bit in the butt by it, either through security or by making a mistake yourself.

SUDO will allow users to perform certain actions as 'root'. That should only be used in instances where the application is not fully matured to allow ordinary users to run it.

I don't understand why you need this access, however. Simply become 'root', install Oracle and the other stuff, then run them as a regular user. Just like any other app.

I believe that oracle has to run as a deamon on the machine with root priviliges, if you disable remote login ability you should be fine..

We all hopefuly know that this is bad security... but hey if someone wants to give a user root, then thats the choice they made.... go ahead.
