JMX监控zookeeper

一.修改 zkServer.sh 参数ZOOMAIN

默认配置

修改后配置

修改说明：

是否建立远程连接，false可远程建立连接 -Dcom.sun.management.jmxremote.local.only=false zookeeper地址 -Djava.rmi.server.hostname=127.0.0.1   连接端口，并不是zookeeper端口，也不能和zookeeper端口冲突  -Dcom.sun.management.jmxremote.port=2180   是否ssl连接，如果JMX无法ssl连接上zookeeper，需要改为false  -Dcom.sun.management.jmxremote.ssl=false    是否开启访问权限  -Dcom.sun.management.jmxremote.authenticate=true    设置访问权限，参考jdk目录/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/management/下该文件  -Dcom.sun.management.jmxremote.access.file=/usr/local/data/zookeeper/conf/jmxremote.access    -Dcom.sun.management.jmxremote.password.file=/usr/local/data/zookeeper/conf/jmxremote.password    是否开日志  -Dzookeeper.jmx.log4j.disable=true

如果不开启访问权限控制去掉以下三个配置：

   -Dcom.sun.management.jmxremote.authenticate=true    -Dcom.sun.management.jmxremote.access.file=/usr/local/data/zookeeper/conf/jmxremote.access    -Dcom.sun.management.jmxremote.password.file=/usr/local/data/zookeeper/conf/jmxremote.password

二. 创建授权文件jmxremote.access和jmxremote.password

参考JDK文件说明
/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/management/jmxremote.access
/Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/management/jmxremote.password

zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$ cd /usr/local/data/zookeeper/conf/ zhenglubiaodeMacBook-Pro:conf zlb$ ls -l total 16 -rw-------  1 root  wheel  149  6 13 15:46 jmxremote.access -rw-------  1 root  wheel   40  6 13 15:48 jmxremote.password zhenglubiaodeMacBook-Pro:conf zlb$ sudo cat jmxremote.access  monitorRole   readonly controlRole   readwrite \               create javax.management.monitor.*,javax.management.timer.* \               unregister zhenglubiaodeMacBook-Pro:conf zlb$ sudo cat jmxremote.password  monitorRole  1234   controlRole  123456 zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$

必须修改这两个文件权限为：-rw------- (600) 只有拥有者有读写权限。

zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$ cd /usr/local/data/zookeeper/conf/ zhenglubiaodeMacBook-Pro:conf zlb$ sudo chmod 600 jmxremote.* zhenglubiaodeMacBook-Pro:conf zlb$ ls -l total 16 -rw-------  1 root  wheel  149  6 13 15:46 jmxremote.access -rw-------  1 root  wheel   40  6 13 15:48 jmxremote.password zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$  zhenglubiaodeMacBook-Pro:conf zlb$

三.重启zookeeper

zkServer.sh restart
观察日志 zookeeper.out

四. JConsole连接

命令行输入
