# synchronization phase can take 
initLimit=10 
# The number of ticks that can pass between  
# sending a request and getting an acknowledgement 
syncLimit=5 
# the directory where the snapshot is stored. 
# do not use /tmp for storage, /tmp here is just  
# example sakes. 
dataDir=/home/bigdata/software/zookeeper-3.4.9/zookeeper_data 
# the port at which the clients will connect 
clientPort=2181 
# The number of snapshots to retain in dataDir 
autopurge.snapRetainCount=5 
# Purge task interval in hours 
autopurge.purgeInterval=1 

进入Zookeeper安装目录, 启动 Zookeeper

bin/zkServer.sh start

验证是否启动 zookeeper 成功

  • 安装 nc
yum install nc 

运行以下命令 , 结果为 imok

echo ruok | nc master 2181 

注意: 上面命令中的 master 是你的主机名
