Root Cause
ES installation requires the cron service. Without installing cron, the installation script did not pass, resulting in an installation error.
Solution
Install cron on the server, and then execute the installation script to install ES. The server can access the Internet, and cron installation can be done online. If the server cannot access the Internet, the installation package can be downloaded offline and installed manually.
Install cron online: Command reference: yum install cron*
