### zookeeper 监控命令 ###

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**docker zookeeper**

**配置文件**

dataDir=/data
    dataLogDir=/datalog
    tickTime=2000
    initLimit=5
    syncLimit=2
    autopurge.snapRetainCount=3
    autopurge.purgeInterval=0
    maxClientCnxns=60
    standaloneEnabled=true
    admin.enableServer=true
    server.1=localhost:2888:3888;2181
    4lw.commands.whitelist=*           //添加配置使用监控命令

**创建容器**

docker run -it -d --net fixed3 --ip 192.168.57.2 \
    -v /usr/zookeeper/single/conf/zoo.cfg:/conf/zoo.cfg \
    --name zoo zookeeper

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**命令使用**

**conf：查看配置信息**

root@4bfed5d69a6b:/apache-zookeeper-3.6.2-bin# echo conf | nc localhost 2181
    clientPort=2181
    secureClientPort=-1
    dataDir=/data/version-2

    maxClientCnxns=60
    minSessionTimeout=4000
    maxSessionTimeout=40000
    clientPortListenBacklog=-1
    serverId=0

**envi：****查看服务器运行时环境信息****(服务器版本、java信息、用户信息、系统信息)**
