Cassandra specifying the database path

Reference https://docs.datastax.com/en/cassandra/2.1/cassandra/configuration/configCassandra_yaml_r.html

We are talking about the way tarball installation, that is, to download the source to the specified path, assuming that it is placed under/home/user/cassandra

There are bin,data,conf and other folders under this path.

By default, both SST and log are stored in the data directory.

Data in the data directory is the SST storage directory, which is classified according to the database name.

Configuration file under Conf, named Cassandra.yaml

How to configure

Data_file_directories:
-/home/leveldb/cassandra/cassandra/data

Be careful not to use the TAP key.

If the specified directory does not exist, the service program creates one itself, so the directory should have permission to modify the service program.
