1.环境准备
创建zookeeper用户.
准备安装包: zookeeper-3.4.8.tar.gz.
拷贝至安装目录并解压
tar zxvf zookeeper-3.3.6.tar.gz
mv zookeeper-3.3.6 zookeeper2.配置文件
- zookeeper/conf/zoo.cfg(需手动创建)
#zookeeper使用的基本时间单位(ms)
tickTime=2000
#leader和follow之间的最长心跳时间(ticktime的倍数)
initLimit=5
#leader和follower之间的消息交换的最长时间(ticktime的倍数)
syncLimit=2
#数据目录
dataDir=/home/zookeeper/zookeeper/data
#日志目录,该目录事先创建,否则无法启动
dataLogDir=/home/zookeeper/zookeeper/logs
#服务端口
clientPort=2181
#server0...分别对应集群中的各台,ip:数据交换端口:leader选举端口
server.0=192.168.163.101:8880:7770
server.1=192.168.163.102:8880:7770
server.2=192.168.163.103:8880:7770
- zookeeper/data/myid(需手动创建)
#唯一标识
0拷贝至其他节点,此文件对应修改.
- .bashrc
export ZOOKEEPER_HOME=/home/zookeeper/zookeeper
export PATH=$ZOOKEEPER_HOME/bin:$ZOOKEEPER_HOME/conf:$PATHsource .bashrc
3.启动
各节分别执行启动
zkServer.sh start注意: 启动第一个节点时,由于其他两个节点未启动,所以会报错,不用管.

- jps查看进程
QuorumPeerMain- 查看节点状态
./zkServer.sh status
- 启动客户端
./zkCli.sh -server localhost:2181
- 创建节点
create /zk ‘test‘
get /zk
