单台机器：
wget https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.8/apache-zookeeper-3.5.8-bin.tar.gz tar -zxvf apache-zookeeper-3.5.8-bin.tar.gz cd apache-zookeeper-3.5.8-bin cp zoo_sample.cfg zoo.cfg bin/zkServer.sh start conf/zoo.cfg ps -ef|grep zookeeper bin/zkCli.sh -server ip:port
增删改查的基本命令：
create [-s] [-e] [-c] [-t ttl] path [data] [acl] get /test-node set /test-node some-data-changed ls /
Zookeeper集群模式安装：
wget https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.5.8/apache-zookeeper-3.5.8-bin.tar.gz tar -zxvf apache-zookeeper-3.5.8-bin.tar.gz cd apache-zookeeper-3.5.8-bin cp conf/zoo_sample.cfg conf/zoo-1.cfg # vim conf/zoo-1.cfg dataDir=/usr/local/data/zookeeper-1 clientPort=2181 server.1=127.0.0.1:2001:3001:participant// participant 可以不用写，默认就是participant server.2=127.0.0.1:2002:3002:participant server.3=127.0.0.1:2003:3003:participant server.4=127.0.0.1:2004:3004:observer cp conf/zoo1.cfg conf/zoo2.cfg cp conf/zoo1.cfg conf/zoo3.cfg cp conf/zoo1.cfg conf/zoo4.cfg vim conf/zoo2.cfg dataDir=/usr/local/data/zookeeper2 clientPort=2182 vim conf/zoo3.cfg dataDir=/usr/local/data/zookeeper3 clientPort=2183 vim conf/zoo4.cfg dataDir=/usr/local/data/zookeeper4 clientPort=2184 cd /usr/local/data/zookeeper-1 vim myid 1 cd /usr/local/data/zookeeper-2 vim myid 2 cd /usr/local/data/zookeeper-3 vim myid 3 cd /usr/local/data/zookeeper-4 vim myid 4 bin/zkServer.sh start conf/zoo1.cfg bin/zkServer.sh start conf/zoo2.cfg bin/zkServer.sh start conf/zoo3.cfg bin/zkCli.sh -server ip1:port1,ip2:port2,ip3:port3
