JMX configuration for Tomcat

Window下执行步骤：

D:apache-tomcat-7.0.57incatalina.bat

set CATALINA_OPTS=-Dcom.sun.management.jmxremote
  -Dcom.sun.management.jmxremote.port=8899
  -Dcom.sun.management.jmxremote.ssl=false
  -Dcom.sun.management.jmxremote.authenticate=true
  -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password
  -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access

D:apache-tomcat-7.0.57confjmxremote.access

# Default access control entries:
# o The "monitorRole" role has readonly access.  
# o The "controlRole" role has readwrite access and can create the standard
#   Timer and Monitor MBeans defined by the JMX API.

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

D:apache-tomcat-7.0.57confjmxremote.password

# In a typical installation, this file can be read by anybody on the
# local machine, and possibly by people on other machines.
# For # security, you should either restrict the access to this file,
# or specify another, less accessible file in the management config file
# as described above.
#
# Following are two commented-out entries. The "measureRole" role has
# password "QED". The "controlRole" role has password "R&D".

monitorRole tomcat
controlRole tomcat

启动Tomcat后，运行如下命令，检测配置效果（注意实际配置的端口号可能不同）：

netstat -an | find "8899"

Linux下执行步骤：

Additional Implementations

JMX Remote Lifecycle Listener - org.apache.catalina.mbeans.JmxRemoteLifecycleListener

This listener requires catalina-jmx-remote.jar to be placed in $CATALINA_HOME/lib. This jar may be found in the extras directory of the binary download area.

The JMX Remote Lifecycle Listener fixes the ports used by the JMX/RMI Server making things much simpler if you need to connect jconsole or a similar tool to a remote Tomcat instance that is running behind a firewall. Only these ports are configured via the listener. The remainder of the configuration is via the standard system properties for configuring JMX. For further information on configuring JMX see Monitoring and Management Using JMX included with the Java SDK documentation.

This listener must only be nested within a Server element.

The following additional attributes are supported by the JMX Remote Lifecycle Listener:

Attribute	Description
rmiRegistryPortPlatform	The port to be used by the JMX/RMI registry for the Platform MBeans. This replaces the use of the com.sun.management.jmxremote.port system property that should not be set when using this listener.
rmiServerPortPlatform	The port to be used by the Platform JMX/RMI server.
rmiBindAddress	The address of the interface to be used by JMX/RMI server.
useLocalPorts	Should any clients using these ports be forced to use local ports to connect to the JMX/RMI server. This is useful when tunnelling connections over SSH or similar. Defaults to false.

Using file-based Authentication and Authorisation

If this listener was configured in server.xml as:

  <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
          rmiRegistryPortPlatform="10001" rmiServerPortPlatform="10002" />

with the following system properties set (e.g. in setenv.sh):

  -Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password
  -Dcom.sun.management.jmxremote.access.file=$CATALINA_BASE/conf/jmxremote.access
  -Dcom.sun.management.jmxremote.ssl=false

$CATALINA_BASE/conf/jmxremote.password containing:

admin letmein

$CATALINA_BASE/conf/jmxremote.access containing:

admin readwrite

then opening ports 10001 (RMI Registry) and 10002 (JMX/RMI Server) in your firewall would enable jconsole to connect to a Tomcat instance running behind a firewall using a connection string of the form:

service:jmx:rmi://<hostname>:10002/jndi/rmi://<hostname>:10001/jmxrmi

with a user name of admin and a password of letmein

1.下载catalina-jmx-remote.jar（支持JMX协议）到tomcat的lib下。

2.配置tomcat的server.xml中的Listener（这样Tomcat收到停止指令时，会通知Listner，不会导致端口被绑定，停不掉的情况）。

3.使用独立的扩展shell（setenv.sh），配置jmx的连接参数。
