JMX是用来远程监控Java应用的框架，这个也可以用来监控其他的Java应用。JMX使用起来也很简单。当然还有一款比较优秀的监控工具就是ZkWeb，本片博客都会简单介绍部署方式。
JMX官方地址：http://zookeeper.apache.org/doc/r3.4.14/zookeeperJMX.html。
ZkWeb的github地址：https://github.com/zhitom/zkweb
分布式协调服务Zookeeper集群搭建：https://www.cnblogs.com/yinzhengjie/p/10747747.html。
一.zookeeper服务开启JMX监控（不推荐使用该方式）
1>.修改zookeeper的启动脚本
.......... #ZOOMAIN="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=$JMXLOCALONLY org.apache.zookeeper.server.quorum.QuorumPeerMain" #将ZOOMAIN的默认配置注释掉！ ZOOMAIN="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false #是否建立远程连接，false可远程建立连接 -Djava.rmi.server.hostname=127.0.0.1 #zookeeper地址 -Dcom.sun.management.jmxremote.port=8888 #JMX连接端口，并不是zookeeper端口，也不能和zookeeper端口冲突 -Dcom.sun.management.jmxremote.ssl=true # 是否ssl连接，如果JMX无法ssl连接上zookeeper，需要改为false -Dcom.sun.management.jmxremote.authenticate=true # 是否开启访问权限,如果设置为true的话，需要指定access和password存放路径，就在下面两行（如果不配置安全认真删除当前行和下面2行即可！） -Dcom.sun.management.jmxremote.access.file=/yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.access # 设置访问权限，需要指定对应的路径，下面哪个文件是指定具体的用户名和密码 -Dcom.sun.management.jmxremote.password.file=/yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.password -Dzookeeper.jmx.log4j.disable=true # 是否开日志 org.apache.zookeeper.server.quorum.QuorumPeerMain" ..........
2>.在“Dcom.sun.management.jmxremote.access.file”和“Dcom.sun.management.jmxremote.password.file”对应的目录下创建相应的文件，结合上面咱们写的文件名称
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.access monitorRole readonly controlRole readwrite create javax.management.monitor.*,javax.management.timer.* unregister [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.password monitorRole 123 controlRole 456 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/zookeeper-3.4.14/conf/ | grep jmxremote -rw-r--r--. 1 root root 148 Apr 25 17:09 jmxremote.access -rw-r--r--. 1 root root 34 Apr 25 17:09 jmxremote.password [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# chmod 600 /yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.* [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/zookeeper-3.4.14/conf/ | grep jmxremote -rw-------. 1 root root 148 Apr 25 17:09 jmxremote.access -rw-------. 1 root root 34 Apr 25 17:09 jmxremote.password [root@node101.yinzhengjie.org.cn ~]#
需要注意的是，如果上面修改的2个文件的权限配置为600，会抛出异常，如下图所示：
[root@node102.yinzhengjie.org.cn ~]# cat zookeeper.out Error: Password file read access must be restricted: /yinzhengjie/softwares/zookeeper-3.4.14/conf/jmxremote.password sun.management.AgentConfigurationError at sun.management.jmxremote.ConnectorBootstrap.checkPasswordFile(ConnectorBootstrap.java:577) at sun.management.jmxremote.ConnectorBootstrap.startRemoteConnectorServer(ConnectorBootstrap.java:426) at sun.management.Agent.startAgent(Agent.java:262) at sun.management.Agent.startAgent(Agent.java:452) [root@node102.yinzhengjie.org.cn ~]#
3>.同步配置文件到其他节点中并重启zookeeper集群
[root@node101.yinzhengjie.org.cn ~]# scp -rp /yinzhengjie/softwares/zookeeper-3.4.14/ node102.yinzhengjie.org.cn:/yinzhengjie/softwares/ ......

按照网上的说法我们就可以使用JConsole等工具可以访问该我们配置的JMX端口，可惜我测试了一个下午都没有搞定！不知道是不是我机器有问题，大家是否遇到跟我一样的问题呢？（还好这种监控我没有弄出来，于是我找到了另外的一款监控工具，基于Web的）
二.zookeeper的web监控工具之ZkWeb（官方地址：https://github.com/zhitom/zkweb）
1>.下载“ZkWeb For Zookeeper”的jar包
下载地址：https://github.com/zhitom/zkweb/releases。
2>.运行ZkWeb的jar包（默认启动端口是8099）
