Mongodb

mongo

db.devices.update({devid:"CYURD001"}, {$set:{loc:{ lat: 14.34500000, lng: -72.44400000, timezone: "America/New_York", address: "12 Parley Vale, Jamaica Plain, MA 02130" }})

var nt = { lat: 14.34500000, lng: -72.44400000, timezone: "America/New_York", address: "12 Parley Vale, Jamaica Plain, MA 02130" }

var nt = { devid: 'YRUDBD0001', domain: 'parley', userarr: [], loc: { lat: 2334555.3344, lng: 12345.2344, timezone: -5, address: '12 Parley Vale, Jamaica Plain, MA 02130' }, users: [], usersarr: []}

back to databases

Mongod defaults the database location to: /data/db/

dump

mongodump -db stuffDb
tar czvf dump.tar.gz dump

restore(first drop existing)

mongo 
 >use stuffDb
 >db.dropDatabase()

tar xvf dump.tar.gz
mongorestore dump

replica set

I'd like to configure replica set for development so I can use mongod on my laptop when the internet is not available and use a server hosted mongod when the internet is available.

so far...

• you need three instances so I've added a third on another host
• rs.add(host) happens on the primary, my laptop has no known url so it needs to be the primary
• before I go offline I need to run mongod on the laptop
• when I have internet, I kill mongod on the laptop causing the serverhosted db to take over as primary (by making the other secondary decline the honor)
• when the laptop mongod comes back up it takes control and gets the current data.
• rinse repeat
