Everytime login subject in the UID name changes sometimes root sometimes the user name x on CentOS


Hi,

I am a new user for the Linux CentOS operating system. And now I'm having a problem on the server with the CentOS release 6.7 Linux OS.
I intend to add a new user with the name systemadm23, and I want to make that user have privileges at the root level so I made it in the etc / passwd like this:

servercentos: ~> cat / etc / passwd | grep systemadm23
systemadm23: x: 0: 0: Emergency User, Security Management: / home / systemadm23: / bin / sh
servercentos: ~>


But when I login using the user as root, why when I type "id" appears like this:
servercentos: ~> id
uid = 0 (systemadm23) gid = 0 (root) groups = 0 (root)


it should be like this "uid = 0 (root) gid = 0 (root) groups = 0 (root)" ??

Please help, because when I want to login using root, uid sometimes changes.

note: please forgive me if there is a way of posting from me that is not appropriate

You are going about this totally the wrong way. UID must be unique, you can't just give another user the UID of 0 and expect it to work.

You need to create your new user as a normal user and then read up on sudo / [/b]sudoers[/b] to allow the user to execute commands at an elevated privilege.

Alternatively you can add the user to the group wheel, again, go read up on sudo/sudoers and things may become clearer.

radeon45, what is the purpose of this?
there is most probably a better way to achieve what you want.

Thank you for your respon.

@TenTenths
Yes, I know. It's not properly way. But it's needed to run specifically application. User systemadm23 will be use for administrator user account of application, and the system of the application will be using it.
In operating systems Linux Suse, I face a similar case too. But, it's have solved after I custom on the sudoers file like what you said.
And I have try to do the same in this Linux CentOS but it's make the application failed to integrate a service to the target server (Linux CentOS).

Any other solution?

@ondoho,

"specific application" is not an explanation of what you want to achieve.

but i guess tentenths is right, you need to set up sudo instead of creating a new root user.
