os: centos 7.6.1810  
db: hbase 2.3.x  
hadoop 2.10.x  
zookeeper 3.6  
jdk 1.8

hbase 是运行在 hadoop 之上，hadoop 又是运行在 jvm 之上。  
索引 hbase、hadoop、jdk 的版本选择就得考虑兼容性

节点规划，实验用

192.168.56.221  hb1
    192.168.56.222  hb2
    192.168.56.223  hb3

# 版本 #

# cat /etc/centos-release
    CentOS Linux release 7.6.1810 (Core)

# zookeeper #

所有节点创建用户，保持 id 一致

# groupadd -g 500 zookeeper;
    useradd -u 500 -g zookeeper -G zookeeper zookeeper;
    
    # passwd zookeeper

下载安装 zookeeper

# cd /usr/local/
    # wget https://downloads.apache.org/zookeeper/zookeeper-3.6.3/apache-zookeeper-3.6.3-bin.tar.gz
    # tar -zxvf ./apache-zookeeper-3.6.3-bin.tar.gz
    # chown -R zookeeper:zookeeper ./apache-zookeeper-3.6.3-bin
    # ln -s ./apache-zookeeper-3.6.3-bin zookeeper-3.6

# su - zookeeper
    $ cd zookeeper-3.6.3
    $ cp ./conf/zoo_sample.cfg ./conf/zoo.cfg
    
    $ egrep ^[a-z] ./conf/zoo.cfg
    tickTime=2000
    initLimit=10
    syncLimit=5
    dataDir=/home/zookeeper/data
    clientPort=2181
    server.1=192.168.56.221:2888:3888
    server.2=192.168.56.222:2888:3888
    server.3=192.168.56.223:2888:3888

hb1 上执行

$ mkdir -p /home/zookeeper/data; echo "1" >> /tmp/zookeeper/myid;

hb2 上执行

$ mkdir -p /home/zookeeper/data; echo "2" >> /tmp/zookeeper/myid;

hb3 上执行

$ mkdir -p /home/zookeeper/data; echo "3" >> /tmp/zookeeper/myid;

每台机器依次启动

$ /usr/local/zookeeper-3.6/bin/zkServer.sh start   /usr/local/zookeeper-3.6/conf/zoo.cfg
    
    $ /usr/local/zookeeper-3.6/bin/zkServer.sh status  /usr/local/zookeeper-3.6/conf/zoo.cfg

/etc/profile 最后面添加变量

# vi /etc/profile
    export ZOOKEEPER_HOME=/usr/local/zookeeper-3.6
    export PATH=.:${ZOOKEEPER_HOME}/bin:${PATH}
