apt-key add - < Release.key 

echo 'deb https://download.arangodb.com/arangodb2/xUbuntu_16.04/ /' | sudo tee /etc/apt/sources.list.d/arangodb.list

yum -y install arangodb-2.8.11
 
firewall-cmd --permanent --add-port=8529/tcp
 
firewall-cmd --reload

Setting Up EndPoint

After installation, you need to bind the ArangoDB service to listen on all inbound endpoints. You can do this by editing the config file as follows:

CODE

cat /etc/arangodb/arangod.conf | sed 's/endpoint = tcp:\/\/127.0.0.1:8529/endpoint = tcp:\/\/0.0.0.0:8529/' > /etc/arangodb/arangod.conf.new ; cp /etc/arangodb/arangod.conf.new /etc/arangodb/arangod.conf 
 
service arangodb restart

Deploying the Centro Database

Alongside the installation files for Centro, you should find a folder named “Deploy” which contains the necessary scripts to install your Centro database.

After copying the “Deploy” folder to your Linux machine, run the following shell script to deploy the database:

CODE

./setup.sh

You will see some output indicating the deployment steps being carried out.

Congratulations, your Centro database is now deployed! When updates become available, you will be able to use the same setup script to install any updates to your database.

You can view the database from http://<Server-IP>:8529/_db/<Database –Name>/

Where Server-IP is the IP address of the server machine you installed ArangoDB on, and Database-Name is the name you used when deploying the database (ActifyDB by default).

If you do not know the IP address of the machine, you can check it by running:

CODE

ifconfig

The IP address will be under inet addr: in the output of the command. This will be the one which corresponds to the eth0 adapter and not local loopback (i.e. the address should not be 127.0.0.0.1).
