Migrating Airnotifier

Sometimes it useful to have a local airnotifier instance for testing, in this document is described step by step how to migrate a working Airnotifier installation to a different server

Install the required dependencies for running airnotifier in the new server See https://github.com/airnotifier/airnotifier/wiki/Installation

Backup the mondodb databases

Applications list database

mongodump -h localhost --port 27017 -d airnotifier -o /var/airnotifier/

Each application database

mongodump -h localhost --port 27017 -d commoodlemoodlemobile -o /var/airnotifier/
mongodump -h localhost --port 27017 -d commoodlemoodlemobiletest -o /var/airnotifier/

Copy the old installation files and databases to the new server

Using a local computer to route the traffic

scp -3 -r root@messages.moodle.net:/opt/airnotifier/* myuser@myhost:/opt/airnotifier/
scp -3 -r root@messages.moodle.net:/var/airnotifier/* myuser@myhost:/var/airnotifier/

Or directly between servers (messages.moodle.net will connect to myhost)

scp -r root@messages.moodle.net:/opt/airnotifier/* myuser@myhost:/opt/airnotifier/
scp -r root@messages.moodle.net:/var/airnotifier/* myuser@myhost:/var/airnotifier/

Import the databases in the new server

mongorestore -h localhost --port 27017 -d airnotifier /var/airnotifier/airnotifier/
mongorestore -h localhost --port 27017 -d commoodlemoodlemobile /var/airnotifier/commoodlemoodlemobile/
mongorestore -h localhost --port 27017 -d commoodlemoodlemobiletest /var/airnotifier/commoodlemoodlemobiletest/

You may check that are correctly imported

mongo
use airnotifier
db.options.find()
use commoodlemoodlemobile 
db.keys.find()
use commoodlemoodlemobiletest 
db.keys.find()

Start the server

sudo -u airnotifier python airnotifier.py >> /var/airnotifier/console_log 2>> /var/airnotifier/error_log &
