zookeeper 3.4.13 安装

创建目录

mkdir /data/bigdata/zookeeper -p
chown hadoop:hadoop /data/bigdata/zookeeper -R

修改配置

mv zoo_sample.cfg zoo.cfg
vim zoo.cfg

# synchronization phase can take

# The number of ticks that can pass between 
# sending a request and getting an acknowledgement

# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data/bigdata/zookeeper
# the port at which the clients will connect
clientPort=2181

server.2=node1:2888:3888

编辑server id

vim /data/bigdata/zookeeper/myid

按服务器编号 依次输入1，2，3
（The myid file consists of a single line containing only the text of that machine's id. So myid of server 1 would contain the text "1" and nothing else. The id must be unique within the ensemble and should have a value between 1 and 255）
