=====Overview=====
The whole setup of Oracle NoSQL, in my opinion, is bananas. Each time I tried to set it up, something always failed.
Luckily, or because of it, some people (oracle) create a script to facilitate the configuration.
The script can be downloaded by cloning [[https://github.com/oracle/nosql-examples|this]] repo:

In this repo, there is a folder called: cluster_setup into which, there is a script called: cluster_setup.sh, they should really come up with a better names :)

Either way, so in our case, we will just configure 2 VMs (using vagrant) and run that setup.


=====Virtual Machines=====
I have done it many times, but the setup of the VMs using vagrant is pretty easy. I have created the following Vagrantfile, based on another Vagrantfile for other shenanigans:

<Code:bash|Vagrantfile>
$allow_shell = <<SCRIPT
sed -i 's/PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config    
systemctl restart sshd.service
SCRIPT

$edit_hosts_file = <<SCRIPT
cat > /etc/hosts <<EOF
127.0.0.1 localhost
192.168.0.101 sn1.example.com sn1
192.168.0.102 sn2.example.com sn2
192.168.0.103 sn3.example.com sn3
EOF
SCRIPT

$install_vnc_server = <<SCRIPT
yum -y install net-tools
yum -y install unzip
yum -y install curl
yum -y install lvm2
yum -y remove java
yum -y install java-1.8.0-openjdk-1.8.0.352.b08-2.el7_9.x86_64
SCRIPT

$config_storage = <<SCRIPT
vgcreate vg_nosql /dev/sdb
lvcreate -L 1G -n lv_disk1 vg_nosql
lvcreate -L 1G -n lv_disk2 vg_nosql
lvcreate -L 1G -n lv_disk3 vg_nosql
mkfs.ext4 /dev/vg_nosql/lv_disk1
mkfs.ext4 /dev/vg_nosql/lv_disk2
mkfs.ext4 /dev/vg_nosql/lv_disk3
cat >> /etc/fstab <<EOF

Vagrant.configure("2") do |config|

	sn.vm.provision "shell", inline: $install_vnc_server, privileged: true
	sn.vm.provision "shell", inline: $allow_shell, privileged: true
	sn.vm.provision "shell", inline: $edit_hosts_file, privileged: true
	second_disk = "C:\\Users\\julie\\VirtualBox VMs\\sn#{i}\\disk_nosql_data.vdi"
    sn.vm.provider :virtualbox do |v|
	# Get disk path
	  v.customize ["modifyvm", :id, "--memory", 2560]
      v.customize ["modifyvm", :id, "--name", "sn#{i}"]
	  v.customize ["storageattach", :id, 
                "--storagectl", "IDE",

                "--type", "dvddrive", 
                "--medium", "emptydrive"]
	  v.customize ['createhd', '--filename', second_disk, '--size', 500 * 1024]
	  v.customize ['storageattach', :id, 
				'--storagectl',
				'IDE',
				'--port', 1, '--device', 0,
				'--type', 'hdd',
				'--medium', second_disk]
     end
	 sn.vm.provision "shell", inline: $config_storage, privileged: true
    end
  end
end
</Code>

As, maybe, you will guess, that will create us 2 Virtual machines, with an additional disk which we will create a volume group, which we will split into 3 and which we will mount each LV to a separate File system...geeesh that is a lot.
Anywho, after this, we should have 2 VMs, running and all installed...but the Oracle NoSQL of course


=====Oracle NoSQL=====
The script pretty much guides you through the entire process, but let's set the steps:

  - Intro screen (Enter)
  - Location of the Oracle NoSQL ZIP file (Enter)
  - Host/IPs of the nodes in the cluster and username to connect (Enter)
  - Installation path (Enter)
  - Store name: DefaultStore (I leave my default) (Enter)
  - A lot of connections and password entering (Unless you configure passwordless authentication...too lazy to do so)
  - Data directory: Enter disks (Enter)
  - Log directories (Up to you if you wanna keep logs) (Enter)
  - Port: 5000 (Enter)
  - Replication Factor: 1, it is a test after all (Enter)

There might be some issues with the JAVA, don't ask me....Oracle
