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
zhenglubiaodeMacBook-Pro:conf zlb$
zhenglubiaodeMacBook-Pro:conf zlb$ JConsole
弹出窗口 选择输入地址 连接端口 用户名 密码
连接后
五.了解JMX、JConsole
