Configuring JMX on the Server Side

Complete the following procedure to configure JMX on the server side when enabling secure client-to-node connections using SSL.

jvm-server.options

There are three files that control Java Virtual Machine (JVM) options:

  • jvm-server.options: options independent of any particular JVM

  • jvm8-server.options: options particular to JVM 8

  • jvm11-server.options: options particular to JVM 11

The location of the jvm [8 | 11] -server.options file depends on the type of installation:

Package installations

/etc/dse/cassandra/jvm [8 | 11] -server.options

Tarball installations

<installation_location>/resources/cassandra/conf/jvm [8 | 11] -server.options

Procedure

  1. If the $LOCAL_JMX setting is present, change it to no.

    "$LOCAL_JMX" = "no"
  2. Enable JMX authentication by setting -Dcom.sun.management.jmxremote.authenticate to true:

    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true
  3. Locate the cassandra-env.sh file. The location of this file depends on the type of installation:

    • Package installations: /etc/dse/cassandra/cassandra-env.sh

    • Tarball installations: <installation_location>/resources/cassandra/conf/cassandra-env.sh

  4. Uncomment the following settings in the cassandra-env.sh file. You must specify the path to appropriate keystore and truststore, including passwords for each.

    You can also use the jvm-server.options file as described in Setting system properties during startup.

    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl=true"
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl.need.client.auth=true"
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.registry.ssl=true"
    JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.keyStore=<path_to_keystore.jks>"
    JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.keyStorePassword=<keystore-password>"
    JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.trustStore=<path_to_truststore.jks>"
    JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.trustStorePassword=<truststore-password>"
    com.sun.management.jmxremote.ssl

    Set to true to enable SSL for JMX.

    com.sun.management.jmxremote.ssl.need.client.auth

    Set to true to enable two-way certificate authentication.

    com.sun.management.jmxremote.registry.ssl

    Set to true to create an RMI registry protected by SSL, and configure a management agent when the JVM starts.
