cassandra - jmx is not enabled to receive remote connections -

-

i not sure why 7199 listening on 127.0.0.1,how can make 7199 listen hostip address.

my cassandra-env.sh config below jvm

jmx_port="7199"

jvm_opts="$jvm_opts -djava.net.preferipv4stack=true"

jvm_opts="$jvm_opts -djava.rmi.server.hostname=192.68.0.45" local_jmx=no

if [ "$local_jmx" = "yes" ]; then

jvm_opts="$jvm_opts -dcassandra.jmx.local.port=$jmx_port -xx:+disableexplicitgc"

else jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.port=$jmx_port"

jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.rmi.port=$jmx_port"

jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.ssl=false"

jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.authenticate=true"

jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.password.file=/etc/cassandra/jmxremote.password"

i have been fighting issue too. been not easy shown on tutorials.

i solved issue this:

  1. add environment variable local_jmx .bashrc file:
      #set local_jmx     export local_jmx=no
  1. at cassandra-env.sh disable password authentication (test environmnent!!):
      jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.authenticate=false"     #  jvm_opts="$jvm_opts -dcom.sun.management.jmxremote.password.file=/etc/cassandra/jmxremote.password"
  1. restart each node(s)
