1.在tomcat的server.xml中加入：

2. 将jdk目录/jre/lib/management下的jmxremote.access、jmxremote.password两个文件放到 CATALINA_HOME/conf目录里面，如果没有jmxremote.password，则从JAVA_HOME/jre/lib /management/jmxremote.password.template拷贝出一个名为jmxremote.password的新文件, 修改文件内容：

jmxremote.password 文件末尾:

admin bibo

jmxremote.access 文件末尾:

admin read

#（这里只要有read权限就够了，不需要readwrite）

ps：帐号是admin，密码是bibo

3.将catalina-jmx-remote.jar加入tomcat目录/lib下

4.修改tomcat /bin/catalina.bat

在rem ----- Execute The Requested Command 下加入

windows下：

set JAVA_OPTS= -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access -Dcom.sun.management.jmxremote.ssl=false

linux下：

CATALINA_OPTS="

-Djava.rmi.server.hostname=192.168.2.201 -Dcom.sun.management.jmxremote

-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"

注意如果要从其他机器通过jconsole连接的话，就一定要有

-Djava.rmi.server.hostname=192.168.2.201，否则会连接不上
