Setting up a ZooKeeper server in standalone mode is straightforward. The server is contained in a single JAR file, so installation consists of creating a configuration.
Once you’ve downloaded a stable ZooKeeper release unpack it and cd to the root
To start ZooKeeper you need a configuration file. Here is a sample, create it in conf/zoo.cfg
意思是需要创建一个配置文件在 conf/zoo.cfg 目录,最简单的格式如下

tickTime=2000
dataDir=/var/lib/zookeeper
clientPort=2181
initLimit=5
syncLimit=2

或者复制一个配置文件 在conf目录下
cp -a zoo_sample.cfg zoo.cfg
记得修改配置

启动:

启动服务器
bin/zkServer.sh start

Using config: /root/zookeeper/zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

连接一个客户端
bin/zkCli.sh -server 127.0.0.1:2181
