/bin/su: Permission denied in CentOS can not set su - root

Question

I'm trying to set myself as a root and once I type in su - root in the terminal it just give me an error saying /bin/su: Permission denied so I checked the permission in that file

-rwsr-x--- 1 root wheel 24120 Mar 30 2011 su*

I'm wondering why I can't use this I'm trying to install some plugin and it asks me to use root thats why I needed it.

Solution

you need to be a member of the wheel group. This restricts su logins to "trusted" users

to be a member of wheel group I have to ask root to add me in the group but Godaddy disable root by default for security reason and they asked me to use su but su it doesn't work thats why :(

does root not have a password? if so try "sudo su -"

myaccount is not in the sudoers file. This incident will be reported.

if you could please add the permissions of the /bin/su and if root has a password set. Also the contents of the group file may help
