Question

$ cd $JAVA_HOME/jre/lib/management
$ cp jmxremote.password.template jmxremote.password
$ chmod u=rw jmxremote.password
$ vi jmxremote.password

Set a password for “monitorRole” and “controlRole”:

monitorRole 12monitor
controlRole 55control

After then when I run JMX server on my machine I got following error.

# java -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.m
agement.jmxremote.authenticate=true  -Dcom.sun.management.jmxremote.ssl=false -D
java.rmi.server.host=47.168.96.31  com.example.Main
Error: Password file read access must be restricted: /root/Downloads/jdk1.6.0_29
/jre/lib/management/jmxremote.password

When I change the file permission with the oen of the following commands jmx server works.

# chmod 400  jmxremote.password

or

# chmod 600  jmxremote.password

But I could not connect it through username/password defined in jmxremote.password file

Answer 1

To add new username/password for JMX authorization, authentication has to be defined
by adding the username in to jmxremote.access file. it should be like when adding username “admin”

>monitorRole   readonly
>admin         readonly
>controlRole   readwrite \
          create javax.management.monitor.*,javax.management.timer.* \
          unregister
