下载zookeeper的安装包

# rpm -ivh jdk-8u25-linux-x64.rpm
# cd /opt/
# wget http://apache.communilink.net/zookeeper/stable/zookeeper-3.4.12.tar.gz
# tar xf zookeeper-3.4.12.tar.gz
# ln -sv zookeeper-3.4.12 zookeeper

配置ZooKeeper

# cd zookeeper/conf/
# cp zoo_sample.cfg  zoo.cfg

# vim zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
server.1=192.168.1.9:2888:3888
server.2=192.168.1.10:2888:3888
server.3=192.168.1.11:2888:3888

# cd /var/
# mkdir zookeeper
# cd zookeeper/
[root@dy-node1 zookeeper]# echo 1 > myid
[root@dy-node2 zookeeper]# echo 2 > myid
[root@dy-node3 zookeeper]#  echo 3 > myid

启动zookeeper

# cd /opt/zookeeper/bin
# ./zKserver.sh start

伪集群配置

所谓伪集群模式，是使用同一台机器，而使用不同的端口

server.1=192.168.1.9:2888:3888
server.2=192.168.1.9:2889:3889
server.3=192.168.1.9:2890:3890

单机模式

server.1=192.168.1.9:2888:3888
