Today began to study the Amazon Cloud host EC2, encountered a problem, I need to install Tomcat on EC2, but the Yum command can only be root user to run, and EC2 default is to Ec2-user user login, so need to switch to the root user login, The results of the study are published as follows:

1, according to the method provided by the official website login to connect to the EC2 server (website recommended for Windows users to use Putty connection)

2, create the root password, enter the following command:

sudo passwd root
