Prerequisites

System Requirements

A Virtual Server (VM) or Machine with at least:

1. 64-bit architecture
2. 15G of memory
3. 10G of disk space on the root drive
4. 30-300G of disk space on a drive mounted at /opt, depending on the files you plan to ingest - low end for images/text, high end for audio/video

Software Requirements

1. CentOS, Version 6.5 OR Ubuntu, Version 12.04 lts (Precise Pangolin)
2. Native installation of Ruby

Steps

1. Using bash as your shell, log in as a regular user (not a root user).
   Note: Make sure your user has full sudo privileges (with or without password).
2. Check to be sure that your environment contains a $USER variable.
   echo $USER should return your current user name.
3. Set a $HYDRA_NAME variable to be the name of this hydra head, HydraDAM. echo "HYDRA_NAME=hydradam" | sudo tee -a /etc/environment

[user@ip.address] echo "HYDRA_NAME=hydradam" | sudo tee -a /etc/environment HYDRA_NAME=hydradam

and load it into your shell environment
source /etc/environment

1. Set the rails environment ($RAILS_ENV) to production
   echo "RAILS_ENV=production" | sudo tee -a /etc/environment
   and load that into your shell environment
   source /etc/environment

[user@ip.address] source /etc/environment [user@ip.address] echo "RAILS_ENV=production" | sudo tee -a /etc/environment RAILS_ENV=production

1. Create the /opt/install directory

sudo chown $USER:$USER /opt  
mkdir -p /opt/install

[user@ip.address] source /etc/environment [user@ip.address] sudo chown $USER:$USER /opt
[user@ip.address] mkdir -p /opt/install

Verification/Validation Steps

echo $USER should return your current user name [user@ip.address] echo $USER user

echo $HYDRA_NAME should return "hydradam"
[user@ip.address] echo $HYDRA_NAME hydradam

echo $RAILS_ENV should return "production" [user@ip.address] echo $RAILS_ENV production
