Updating to 1.0

With the release of Rocket.Chat 1.0 a few things have changed to prevent the need for breaking changes down the road.

Oplog Required

With 1.0 we now require oplog be enabled. Attempting to start Rocket.Chat without oplog will result in an error.

To enable you will need to connect to mongo and type rs.initiate()

Then for Rocket.Chat you will need to provide the MONGO_OPLOG_URL environment url. If mongo is on the same host the environment variable will look something like this:

MONGO_OPLOG_URL=mongodb://localhost:27017/local?replicaSet=rs01

For more information see here

Mongo Authentication

If you are using mongo authentication you might also need to add the clustermonitor role to your user.

You can execute something like:

admin = db.getSiblingDB("admin");
admin.grantRolesToUser('OPLOGUSER',[{ role: "clusterMonitor", db: "admin" }])
admin.grantRolesToUser('ROCKETUSER',[{ role: "clusterMonitor", db: "admin" }])

Replace the users with the names you have chosen for your users.
