在%JBOSS_HOME%/bin/run.sh文件中将

#-Djava.rmi.server.hostname=192.168.2.2 #this must be added for Tomacat6
//for Tomcat ... find #Execut The Requested Command in catalina.sh file.可以在Jconsole里实现远程监控了：
远程进程 192.168.10.31:8950
或 service:jmx:rmi:///jndi/rmi://192.168.10.31:8950/jmxrmi
注意：9999表示监控的端口号，确保指定的端口不被占用；可以采用netstat -an来查看已经占用的端口；配合lsof -i:portnum来查看占用端口的具体应用程序；另外如果开启了防火墙服务，请确保端口能够透过防火墙访问；
- 启动JBoss服务器
./run.sh -b192.168.1.5，必须通过-b参数指定Jboss服务器绑定的地址；(不是必须的。。。看每台Server的配置而言)

配置jmx访问密码
1． 修改上文中的catalina脚本中的JAVA_OPT参数，将
-Dcom.sun.management.jmxremote.authenticate="false" 修改为：
-Dcom.sun.management.jmxremote.authenticate="true"2． 将$JRE/lib/management/jmxremote.password.template文件在同目录下复制一份，重命名为$JRE/lib /management/jmxremote.password，编辑jmxremote.password，添加允许访问的用户名及密码，比如添加用户 zxwh，密码为zxme，则在文件尾添加一行：
zxwh zxme
注意用户密码不能包含空格，tab等字符3． 编辑$JRE_HOME/lib/management/jmxremote.access文件，对刚才添加的用户赋予一定的权限：
zxwh readonly （或者readwrite）4． 确认jmxremote.password和jmxremote.access两个文件中的用户是相同的。注意如果jmxremote.access中没有对应用户的话，配置是无效的。
注：以上配置文件的位置都是可以更改的，具体配置方法在此不再赘述。5． 由于jmxremote.password中的密码都是明文保存的，所以jmxremote.password、jmxremote.access文件的权限要注意，应该设置为只有owner才可读，当然这个用户也必须是启动tomcat的用户。
6． 启动jconsole进行连接，在用户名和口令处输入设定的用户和密码。
7． 使用密码认证方式进行连接，不但可以提高安全性，而且可以对用户的权限进行设置。如果不使用密码认证的方式，则无法对用户的权限进行限制。
