Error: Failed to connect to ’127.0.0.1:7199′: Connection refused (Cassandra) [SOLVED]

Error While Using Cassandra’s ‘nodetool’


This error may occur when using the ‘nodetool’ command, such as in the following example:

nodetool status


For both CentOS 6 and CentOS 7 search the following configuration file:

vim /etc/cassandra/default.conf/cassandra-env.sh


Search for:

JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=


Which for my search resulted in:

# add this if you’re having trouble connecting:
# JVM_OPTS=”$JVM_OPTS -Djava.rmi.server.hostname=<public name>”


Uncomment the second line, and add the hostname of your server, or the IP address which you’re connecting to/from. In this case, replacing <public name> with 127.0.0.1 resolved the issue, because I am connecting to/from that IP address.


Then exit and save the file with the command :wq .


Be sure to restart Cassandra:

systemctl restart cassandra
