For Amazon Linux 2 you can use sudo su

[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ cat /etc/os-release
NAME="Amazon Linux"
VERSION="2"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL=""
[ec2-user@ip-xxx-xxx-xxx-xxx ~]$ sudo su
[root@ip-xxx-xxx-xxx-xxx ec2-user]# whoami
root

It's working now, need to create password for root by typing "passwd" command and set password for root. To switch user "su root" command.
