I searched online and found a solution to Put a Password
	
	
	
		
when I run this command, SSH asked me to enter my new Password
and I entered my password, it not displayed on the screen
again it asked me to confirm and enter again...
I have done,
Meanwhile, I referred many sites so I found a solution to run the update command.
	
	
	
		
now server updated
but, then I run command
	
		
 to change the user to root...
but it failed so
I run
	
		
now it changed to [root@ip-172-31-31-9 ~]#
when I close putty and open again using PUTTY, Then it opens with username "centos"
is that OK?
I think we did not change the user name or change the folder name.
So keeping Centos as it is, OK?
you said,
	
		
command to run the Update? then set a password is necessary?
