安装zookeeper

注：试过apache-zookeeper-3.5.5，启动不了

下载、配置相关目录及文件

wget -P /root/software/ http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.14/zookeeper-3.4.14.tar.gz
tar zxf /root/software/zookeeper-3.4.14.tar.gz -C /usr/local
mkdir -p /opt/zookeeper/data
mkdir -p /opt/zookeeper/log
cd /usr/local/zookeeper-3.4.14/conf
egrep -v '#|^$' zoo_sample.cfg > zoo.cfg

修改配制文件/usr/local/zookeeper-3.4.14/conf/zoo.cfg

dataDir=/opt/zookeeper/data
dataLogDir=/opt/zookeeper/log	

配制环境变量 /etc/profile

export ZOOKEEPER_HOME=/usr/local/zookeeper-3.4.14
export PATH=$PATH:${ZOOKEEPER_HOME}/bin

source /etc/profile

启动zookeeper

zkServer.sh start
zkServer.sh status

简单操作 zkCli.sh

#创建节点
create /test parent
create /test/sub child
#查看节点内容
get /test
#查看子节点
ls /
ls /test
#删除节点
delete /test/sub
delete /test
