28.1. Adjusting remote JMX access to the Neo4j Server

Per default, the Neo4j Enterprise Server edition do not allow remote JMX connections, since the relevant options in the conf/neo4j-wrapper.conf configuration file are commented out. To enable this feature, you have to remove the # characters from the various com.sun.management.jmxremote options there.

When commented in, the default values are set up to allow remote JMX connections with certain roles, refer to the conf/jmx.password, conf/jmx.access and conf/neo4j-wrapper.conf files for details.

Make sure that conf/jmx.password has the correct file permissions. The owner of the file has to be the user that will run the service, and the permissions should be read only for that user. On Unix systems, this is 0600.

On Windows, follow the tutorial at http://docs.oracle.com/javase/7/docs/technotes/guides/management/security-windows.html to set the correct permissions. If you are running the service under the Local System Account, the user that owns the file and has access to it should be SYSTEM.

With this setup, you should be able to connect to JMX monitoring of the Neo4j server using <IP-OF-SERVER>:3637, with the username monitor and the password Neo4j.

Note that it is possible that you have to update the permissions and/or ownership of the conf/jmx.password and conf/jmx.access files — refer to the relevant section in conf/neo4j-wrapper.conf for details.

[Warning]Warning

For maximum security, please adjust at least the password settings in conf/jmx.password for a production installation.
