Install

Requirements

• Erlang R15B03+ for high-performance core components
• Postgres 9.1+ with hstore extension for data store
• Node.js 0.8+ for apps, tests, client libraries, etc.

Zephyr runs on OSX and Linux. Windows has not yet been tested.

Troubleshooting

The most common problem setting up Zephyr requirements is upgrading Erlang or installing over an existing Erlang.

Refer to Troubleshooting Guide for help.

OSX

brew install postgres
brew install nodejs

CentOS

You'll likely need to install Postgres, Erlang, and Node.js from source.

If you're using an AWS EC2 RedHat instance, you can "yum install postgresql9-server postgresql9-contrib" and then manually install Erlang and Node.js.
