i have installed Issabel on AWS and before the installation there was no root password
after i finished installing Issabel i found that there is a password for the root user
i tired again with making password before installation found it changed.
ahmedsopeah the root password is not changed.. the sudoers configuration is broken during issabel installation using the script. You need to change the root password before run the script, in order to have it and could using it after the issabel installation.
thank you really
i found that the user that password changed is centos user
and when sudo su -
asking for centos password not for root password
and when i tried su - with out sudo asked for root password
