  • zookeeper的管理功能

    一,查看当前zookeeper的版本

    [liuhongdi@localhost ~]$ echo stat|nc 127.0.0.1 2181
    Zookeeper version: 3.5.6-c11b7e26bc554b8523dc929761dd28808913f091, built on 10/08/2019 20:18 GMT

    说明:架构森林是一个专注架构的博客,地址:https://www.cnblogs.com/architectforest

             对应的源码可以访问这里获取: https://github.com/liuhongdi/

     说明:作者:刘宏缔 邮箱: 371125307@qq.com

    二, 查看当前服务器上管理的Watcher的概要信息

    命令: wchs

    [liuhongdi@localhost ~]$ echo wchs | nc localhost 2181
    1 connections watching 1 paths
    Total watches:1

    三,查看当前服务器上管理的Watcher的详细信息:以会话为单位进行归组

    [liuhongdi@localhost ~]$ echo wchc | nc localhost 2181
    0x10000cf102c0000
        /lockdemo

    四,查看当前服务器上管理的Watcher的详细信息:节点路径为单位进行归组

    [liuhongdi@localhost ~]$ echo wchp | nc localhost 2181
    /lockdemo
        0x10000cf102c0000

    五,输出比stat命令更为详尽的服务器统计信息

    [liuhongdi@localhost ~]$ echo mntr | nc localhost 2181
    zk_version    3.5.6-c11b7e26bc554b8523dc929761dd28808913f091, built on 10/08/2019 20:18 GMT
    zk_avg_latency    0
    zk_max_latency    41
    zk_min_latency    0
    zk_packets_received    4786
    zk_packets_sent    4789
    zk_num_alive_connections    2
    zk_outstanding_requests    0
    zk_server_state    standalone
    zk_znode_count    7
    zk_watch_count    2
    zk_ephemerals_count    0
    zk_approximate_data_size    82
    zk_open_file_descriptor_count    47
    zk_max_file_descriptor_count    4096

    六,检查zookeeper服务器是否正在运行

    [liuhongdi@localhost ~]$ echo ruok | nc localhost 2181
    imok

    七,输出zookeeper服务器的运行环境

    [liuhongdi@localhost ~]$ echo envi | nc localhost 2181

    说明:输出包括了java版本,linux版本,zookeeper运行用户,内存使用情况

    八,查看当前zookeeper服务器上所有连接的信息

    [liuhongdi@localhost ~]$ echo cons | nc localhost 2181

    九,使用zktop做为管理工具

    1,下载地址

    https://github.com/phunt/zktop

    2,解压缩

    [root@localhost source]# unzip zktop-master.zip 
    [root@localhost source]# cd zktop-master/
    [root@localhost zktop-master]# ls
    LICENSE.txt  README.textile  setup.cfg  setup.py  zktop.py

    3,运行zktop

    [root@localhost zktop-master]# /usr/bin/python3.6 ./zktop.py --servers "localhost:2181"
