7.7.2.2. Tomcat JMX for Linux

  • Edit bin/setenv.sh the following way:

    CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote \
-Djava.rmi.server.hostname=192.168.10.10 \
-Dcom.sun.management.jmxremote.port=7777 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=true"

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access"

    Here, the java.rmi.server.hostname parameter should contain the real IP address or the DNS name of the computer where the server is running; com.sun.management.jmxremote.port sets the port for JMX tools connection

  • Edit conf/jmxremote.access file. It should contain user names that will be connecting to the JMX and their access level. For example:

    admin readwrite

  • Edit the conf/jmxremote.password file. It should contain passwords for the JMX users, for example:

    admin admin

  • The password file should have reading permissions only for the user running the Tomcat server. Permissions for the current user can be configured the following way:

    • Open the command line and go to the conf folder.

    • Run the command:

      chmod go-rwx jmxremote.password
