Now i cannot login into the server as root through ssh.

This is the default for CentOS. Edit the /etc/ssh/sshd_config and remove the comment from the "PermitRootLogin yes" directive. Restart the sshd server. Remember, enabling root login is a bad idea, unless you know what you are doing.

I think you need a "Quick and Dirty Guide To Basic Linux Administration". Google around, there are hundreds of books, howto, FAQ, and so on. – AndrewQ Jun 19 '13 at 08:44
could you help me how to login as root user again ? now the access denied. i neet to login into yhe system as root for some modifications. thats why i asked? – Maneesh Mohanachandran Jun 19 '13 at 08:46
I manage 10 remote CentOS installations in this way: ssh using a standard user (non-root). Then I do a "su -" command. It will ask you the password for the root user. If the password is valid, you become root. – AndrewQ Jun 19 '13 at 08:48

Not to be rude, but since you do not know the bare basics of systems administrations, I would strongly advise against installing PHPmyadmin right now. You need to first learn the basics. Otherwise you can expect to have your system compromised in short order. – Jenny D Jun 19 '13 at 09:09

You probably have PermitRootLogin no in your sshd configuration.

Remove the leading '#' – AndrewQ Jun 19 '13 at 08:35
it is commented out - still remote root logins are a bad idea – thanasisk Jun 19 '13 at 08:36

you will need root level access to modify the file. – thanasisk Jun 19 '13 at 08:41

@ManeeshMohanachandran - it sounds like you need to read a Linux 101 webpage to at least learn the basics of the OS first – Mark Henderson Jun 19 '13 at 08:41
@ManeeshMohanachandran You can't edit that file, or restart the ssh service, without having root privileges... – pauska Jun 19 '13 at 08:41
You aren't root. Switch to root user. – AndrewQ Jun 19 '13 at 08:41
i cannot switch to root user. The access is denied. how to enable it again? – Maneesh Mohanachandran Jun 19 '13 at 08:47
If you can, su, or use sudo. If you can't, use the local console. Failing that, you've locked yourself out. – Falcon Momot Jun 19 '13 at 08:51

Terribly worded question, shows no research or attempt to help yourself - thoroughly deserves closing immediately.

That said have you looked in /etc/ssh/sshd_config for a line saying "PermitRootLogin no", if it's there then change it to 'yes' and do a "/etc/init.d/sshd restart" to make the change come into effect.

Oh and don't post again until you've read our FAQ, instead of skipping it, and therefore know what we expect of question askers ok.

i didn't change that part still its #PermitRootLogin Yes – Maneesh Mohanachandran Jun 19 '13 at 08:35
The # means that the line is commented out, i.e. not in effect. – Jenny D Jun 19 '13 at 08:46
