一、配置 java 环境

apt install openjdk-8-jdk
java -version 
openjdk version "1.8.0_222" 
OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10) 
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

二、部署 ZooKeeper

官网下载地址：https://archive.apache.org/dist/zookeeper/

cd /usr/local/src
tar xvf zookeeper-3.4.14.tar.gz
ln -sv /usr/local/src/zookeeper-3.4.14 /usr/local/zookeeper 
'/usr/local/zookeeper' -> '/usr/local/src/zookeeper-3.4.14'

cd /usr/local/zookeeper/conf/
cp zoo_sample.cfg zoo.cfg

grep ^[a-Z] zoo.cfg    #当前配置 
tickTime=2000 
initLimit=10 
syncLimit=5 
dataDir=/tmp/zookeeper 
clientPort=2181

三、启动 ZooKeeper

/usr/local/zookeeper/bin/zkServer.sh 用于启动、重启、停止 ZooKeeper

/usr/local/zookeeper/bin/zkServer.sh start 
ZooKeeper JMX enabled by default 
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg 
Starting zookeeper ... STARTED

四、验证 Zookeeper 进程

ps -ef | grep zookeeper

五、验证 Zookeeper 状态

/usr/local/zookeeper/bin/zkServer.sh status 
ZooKeeper JMX enabled by default 
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg 
Mode: standalone
