  • maxSessionTimeout
  • fsync.warningthresholdms
  • autopurge.snapRetainCount
  • autopurge.purgeInterval
  • electionAlg
  • initLimit
  • leaderServes
  • server.x=[hostname]:nnnnn[:nnnnn], etc
  • syncLimit (默认5)

4字命令

echo stat | nc 192.168.1.105 2181
echo conf | nc 192.168.1.105 2181
<!-- 根据单机和集群显示不同信息 -->
echo cons | nc 192.168.1.105 2181
echo crst | nc 192.168.1.105 2181
<!-- 重置所有信息 -->
echo drop | nc 192.168.1.105 2181
echo envi | nc 192.168.1.105 2181
echo ruok | nc 192.168.1.105 2181
echo stat | nc 192.168.1.105 2181
echo srvr | nc 192.168.1.105 2181
echo srst | nc 192.168.1.105 2181
echo wchs | nc 192.168.1.105 2181
echo wchc | nc 192.168.1.105 2181
echo wchp | nc 192.168.1.105 2181
echo mntr | nc 192.168.1.105 2181

在运维中使用JMX

  1. 修改ZK服务器的启动脚本(每一台)
    Vim zkServer.sh

    + zooMain="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=true org.apache.zookeeper.server.quorum.QuorumPeerMain"
    * zooMain="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false  -Djava.rmi.server.hostname=192.168.1.105 -Dcom.sun.management.jmxremote.port=8899 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false org.apache.zookeeper.server.quorum.QuorumPeerMain"

    ./zkServer.sh stop
    ./zkServer.sh start

  2. jconsole

监控平台的搭建和使用

  • netflix: exhibitor
  • zabbix
