Ubuntu default login user name is the default ubuntu, is the root user without password, no login permissions,After using Ubuntu account login successful want to obtain root access can enter sudo su - command, after will ask for sudo password, fill in Ubuntu account login password, you can switch to the root,
In addition, after the switch to root, can also perform the passwd root gives the root account password, so you can directly use the root login, but it will reduce the security of the original intention Ubuntu system operation,
