Running the Metatron with Virtual Box

Metatron is a web based solution. You need to operate a web server to use the Metatron solution. General users might have difficulties in this part. We support a virtual box for Metatron with minimal functions. With this, you can use and test Metatron easy and quick.

Get Metatron image

First, you need to download Oracle VM Virtual Box through web site.(https://www.virtualbox.org/)
Make sure to allow Oracle to install software in your Mac settings. To get more details, see this link.
Execute the Vitual Box, Then open(File > Import Appliance) the ‘Metatron Discovery.ova’ image file we provide.

Start VM

Check the image settings, and then ‘start’ the virtual machine.

 

Waiting for load

If you get the black window like this capture, then the server is on now. After the server is on, Metatron service is going to be started. It will take several(1~3min.) minutes.

 

Login to Metatron

When the service is on, then access http://127.0.0.1:18180/ through any web browser. If you get this screen, you can now use Metatron by single mode.
Congratulations! We already set your account for this version of Metatron: ID: admin, PW: admin. Now, all you need to do is using and testing Metatron’s basic functions. Please note that this version does not support distributed system for large data.

 

Use Metatron

Pre-precess data, add data from your local, query to check data, and make dashboard with charts through single version of Metatron.

 

For further configurations

In the Metatron single version server, Metatron distributed Druid and Metatron Discovery are installed. Druid is operated on single mode in this package.

Accounts

Here are the pre-set accounts for our systems:
id: root, pw: metatron
id: metatron, pw: metatron

Port forwarding

We don’t provide more contact into VM except discovery’s port, because it could defect initial running in general usage. (Someone could already use our pre-defined port) So, we just suggest a guide about how to connect to other port in general. In VirtualBox Manager popup, go to ‘Setting’ > ‘Network’ tab and expand ‘Advanced’, then there is a ‘Port Forwarding’ menu.

Then, you can define the port forwarding rule like our default setting.
Our recommandation for using druid, set rule for these port :
coordinator: 8081
overload: 8090

Finally, you have to open a port in the firewall on VM using this command.

sudo firewall-cmd --permanent --zone=public --add-port={YOUR_PORT}/tcp 

Then reload the firewall.

sudo firewall-cmd --reload
