#### Version 3.2 ####
#### For questions or comments contact@mylinux.work ####
#### Author : Phil Connor ####
#### ####
#### Notes : ####
#### This script is a simple "helper" to install and configure Maria, ####
#### PowerDNS and PowerAdmin on Linux servers. ####
#### Supported: Ubuntu, Debian, RHEL/CentOS/Rocky/Alma, Fedora, openSUSE ####
#### There is no silver bullet. Don't expect the perfect setup, ####
#### review comments and adapt the parameters to your application usage. ####
#### ####
#### Use this script at your OWN risk. There is no guarantee whatsoever. ####
#### ####
#### Usage chmod 755 then ./PdnsInstall.sh or bash PdnsInstall.sh ####
