For Cassandra follow the instructions at http://cassandra.apache.org/download/
After installing Cassandra you should create the two keypspaces that Mainflux uses:
After installing Cassandra you should create the two keyspaces that Mainflux uses. This can be done with something similar to:
cqlsh> CREATE KEYSPACE IF NOT EXISTS manager WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
cqlsh> CREATE KEYSPACE IF NOT EXISTS message_writer WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };
Please note that in the example SQL statment above, the keyspaces will be created in a single datacenter (single cluster) and there will
only be one replica (copy) of the data. You should create the keyspaces with parameters appropriate for your Cassandra installation. Take a look
at the Cassandra documentation for creating keyspaces for more details. For production usage you should always configure multiple replicas in order
to have data redundancy and be safe in case one or more Cassandra cluster nodes fail.
For NGINX follow the instructions here: http://nginx.org/en/docs/install.html
