Access to Ubuntu root access

Programme one:

The root password of Ubuntu is random before it is set, that is, his password is different at each boot, but because an account needs to be created when Ubuntu is installed, and this greeting belongs to the Admin group, it can change the password for root.

change root password   sudo passwd root   login   root account su  root                            lock root account   sudopasswd - L root         unlock root account   sudopasswd -U root

Scenario Two:

By modifying its own ID in/etc/passwd to gain root privileges, the ID of the account root is 0, so when the account ID you use becomes 0, you will naturally get all the permissions of root.

Use Vim to open/etc/sudo vim/etc/passwd

After entering/etc/passwd This file, find the greeting to get root permission, change the UID to 0, then the account can get root permission.
