.UnavailableSocketError: Inet address 127.0.0.1:7000 is not available

Question

I tried to create a cluster with three Cassandra nodes on my machine.I have unpacked tar.gz and changed listen and rpc_addresses, also JMX_PORT.It did not work

~/apache-cassandra-3.11.1-1/bin$ nodetool -h 127.0.0.02 -p 8081 ring
nodetool: Failed to connect to '127.0.0.02:8081' - ConnectException: 'Connection refused (Connection refused)'.

Then I followed ALex Ott;s adviced,installed ccm.Then I have problem again

ccm start
Traceback (most recent call last):
  File "/home/jholmes/anaconda3/lib/python3.6/site-packages/ccm-3.1.3-py3.6.egg/ccmlib/common.py", line 513, in assert_socket_available
OSError: [Errno 98] Address already in use

During handling of the above exception, another exception occurred:

How to check address the availability?

Before starting CCM, check if you have a Cassandra instance already running. If you do, kill it, then start CCM again. — Pedro Gordo, Jan 22 '18 at 16:33

127.0.0.02 does not look like a valid IP
