Open the Rocket.Chat service file just created (/lib/systemd/system/rocketchat.service) using sudo and your favourite text editor, and change the ROOT_URL environmental variable to reflect the URL you want to use for accessing the server (optionally change MONGO_URL, MONGO_OPLOG_URL and PORT):

sudo sed -i "s/^#  engine:/  engine: mmapv1/"  /etc/mongod.conf

sudo sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf

sudo systemctl enable mongod && sudo systemctl start mongod

mongo --eval "printjson(rs.initiate())"
