===CentOS 7 notes===

Setup storage engine and replication for MongoDB (mandatory for versions > 1), and enable and start MongoDB and Rocket.Chat:
 +
 +
They still recommend mmapv1 but it is probably better to stick with the default WiredTiger. Here's how to change if required:
 +
 +
sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf
 +
 +
You MUST initialise a replicaset so we must add this to the conf file:
 +
 +
sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf
 +
 +
Start Mongo
 +
 +
systemctl enable mongod && sudo systemctl start mongod
 +
 +
Initiate the set:
 +
 +
mongo --eval "printjson(rs.initiate())"
