zookeeper使用(五)---zookeeper开启JMX服务

一、zookeeper单点配置

1. 配置普通单点zookeeper

请参考:zookeeper单点配置

二、zookeeper开启JMX服务

1. 打开 zkServer.sh脚本

注意不要修改错了ZOOMAIN变量，修改为截图的样子

-Dcom.sun.management.jmxremote 
-Djava.rmi.server.hostname=$JMXHOSTNAME  //一定要有这项
-Dcom.sun.management.jmxremote.port=$JMXPORT 
-Dcom.sun.management.jmxremote.authenticate=$JMXAUTH 
-Dcom.sun.management.jmxremote.ssl=$JMXSSL 
-Dzookeeper.jmx.log4j.disable=$JMXLOG4J  
org.apache.zookeeper.server.quorum.QuorumPeerMain

2. 打开 zkEnv.sh脚本

这个脚本是zkServer.sh启动时使用的环境变量脚本,修改为

JMXLOCALONLY=false //修改为false
JMXHOSTNAME=xxx.xxx.xxx.xxx //你的ip 
JMXPORT=21811
JMXSSL=false
JMXLOG4J=false

3. 使用zkServer.sh重启zookeeper

shell> ./zkServer.sh restart
.......
Stopping zookeeper ... STOPPED
ZooKeeper JMX enabled by default
ZooKeeper remote JMX Local Only set to false
ZooKeeper remote JMX Hostname set to xxx.xxx.xxx.xxx
ZooKeeper remote JMX Port set to 21811
ZooKeeper remote JMX authenticate set to false
ZooKeeper remote JMX ssl set to false
ZooKeeper remote JMX log4j set to false
Using config: /etc/zookeeper/conf/zoo.cfg
Starting zookeeper ... STARTED

三、使用jConsole连接zookeeper

1. cmd启动jConsole

打开windows的cmd，输入jConsole，弹出的界面上输入：
