  1. Rahul Shekhawat, I would suggest the implementation of a MySQL path. The first place the bad guys look when they have access to a server is the cron jobs and running processes. Beautiful script, the design is very thin and precise.

    The thought around the MySQL path is that you can really lock it down, to the point that it has very limited abilities and 1 point of access on the user. This way they can’t use this user in an exploit or from another location. The only grant required is REPLICATION CLIENT
    Example: GRANT REPLICATION CLIENT ON *.* to rep_monitor@script_location_ip_address IDENTIFIED BY ‘the_password_you_want_to_use’;

    • Richard, Thanks for your comment.
      The authentication is used in the script is very basic. As per security concerned, anyone can modify the script as per there requirements.
