Canopy Cloud Service

Canopy Cloud Service is the server-side component of Canopy. The main executable is canopy-cloud-service, which is written in golang. Some of its responsibilities include:

• Talking over websockets to each device.
• Storing data in a Cassandra database.
• Serving the Canopy REST API.

sudo apt-get install golang

cd canopy-cloud
make

Install it:

sudo make install

Initialize database:

Notes for older systems (specifically: Ubuntu 12.04 LTS):

Installing cassandra 2.07 on Ubuntu 12.04LTS:

$ sudo vim /etc/apt/sources.list.d/cassandra.sources.list
deb http://debian.datastax.com/community stable main

$ curl -L http://debian.datastax.com/debian/repo_key | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install cassandra=2.0.7

For cassandra to run, it needs oracle java 1.7:

$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java7-installer

The gocql package requires golang 1.1 or later. Ubuntu 12.04 installs 1.0 by default. To updgrade:
