一：Window7下配置方式。

1、配置catalina.bat 在第一行加入下面配置注意下面这些配置要在一行，注意包含空格。

set JAVA_OPTS=-Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.10.126 -Dcom.sun.management.jmxremote.port=9008 -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access

-Djava.rmi.server.hostname=xxx.xxx.xxx.xxx 主机地址，内网就写内网地址，外网就写外网地址。

-Dcom.sun.management.jmxremote.port=xxx 端口号、配置完端口号之后需要将此端口开放出来，注意防火墙拦截。

-Dcom.sun.management.jmxremote.authenticate=true是否开启认证、false的时候可以不使用密码访问。

如果不开启认证，下面配置可以省略。

以下配置是开启认证时使用的access文件和password文件。

-Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password

-Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access

2、拷贝授权文件，这二个文件在 \jdk1.7.0_07\jre\lib\management 文件夹下有模板文件，拷贝一份.放到tomcat/conf文件夹下面。

jmxremote.access

monitorRole   readonlycontrolRole   readwrite \              create javax.management.monitor.*,javax.management.timer.* \              unregister

jmxremote.password

monitorRole  admin123controlRole  admin321

3、给密码文件授权,不然tomcat startup.bat闪退.

需要修改jmxremote.password文件的访问权限，只有运行Tomcat的用户才能拥有访问权限：Windows的NTFS文件系统下，选中文件，点右键 -->“属性”-->“安全”--> 点“高级”--> 点“更改权限”--> 去掉“从父项继承....”--> 弹出窗口中选“删除”，这样就删除了所有访问权限。再选“添加”--> “高级”--> “立即查找”，选中你的用户（或用户组，如果选用户不行那就选用户组），例administrator，点“确定"，“确定"。来到权限项目窗口，勾选“完全控制”，点“确定”，OK了。

4、重新启动Tomcat，在Windows命令行输入“ntstat -a”查看配置的端口号是否已打开，如果打开，说明上面的配置成功了。

二：Linxu下配置

1、配置startup.sh

export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9008 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Djava.rmi.server.hostname=136.16.19.82 -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access"

把上面的配置加在 exec "$PRGDIR"/"$EXECUTABLE" start "$@" 这句话的前面。

2、制作授权文件和windows上面说的一样。

路径也可以写成绝对路径

-Dcom.sun.management.jmxremote.password.file=/usr/apache-tomcat-7.0.47/conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=/usr/apache-tomcat-7.0.47/conf/jmxremote.access"

3、授权 chmod600jmx* 给文件授权，不然tomcat无法启动。

4、重新启动tomcat 在输入命令 netstat -an | grep 9008 查看端口是否被占用，如果占用，说明上面的配置成功了。

三、Java代码调用

       environment = new HashMap
      
       (); 64             // 用户名密码，在jmxremote.password文件中的密码 65             String[] credentials = new String[] {"controlRole", "admin321"}; 66             environment.put("jmx.remote.credentials", credentials); 67             jmxConnector = JMXConnectorFactory.connect(ServiceURL, environment); 68  69             MBeanServerConnection mBeanServerConnection = jmxConnector 70                     .getMBeanServerConnection();
