1. Preparation for Gluu Server installation

Read this guide for the installation: https://gluu.org/docs/gluu-server/4.2/installation-guide/

Now take the decision with a supported by Gluu Server Linux distribution, I decide to use CentOS 

Simple, because there 0 license fees and its binary compatible to RHEL installation packets.

Now before going further make sure that your machine or vm meets following criteria, I recommend to go above , because with minimum req you would be to install Gluu server , but probably wouldn't perform as you expect! 

So here are minimum requirements for the VM instance:

4 GB RAM

2 GB swap space

2 CPU units

40 GB disk space

So this basically how my test machine in Vmware look like:

Initially I tried with minimal setup, but it didn’t worked as I expected

and with this setup all worked out ;)

And this how I partition my test machine and I use everywhere ext4 ;)

• SWAP  8 GB
• Boot    1 GB
• /  Rest 51 GB

All looks great!

Open port 443 with following command:

firewall-cmd --zone=public --add-port=443/tcp --permanent
firewall-cmd --reload

Installation of CentOS is complete! 

What’s next?!
