tar -zxvf zookeeper-3.4.6.tar.gz
cp -a conf/zoo_sample.cfg conf/zoo.cfg
修改配置文件
vi conf/zoo.cfg

这里我使用的3台虚拟机，这里主要设置server.X的X参数
在对应的每台机子上的/opt/zookeeper/myid设置为对应的X
将zk的文件scp到centos1,2,3各自一份
增加内存
zkEnv.sh
#在文件底部增加
export JVMFLAGS="-Xms1024m -Xmx2048m $JVMFLAGS"
查询内存大小
ps -ef|grep zookeeper
#查询pid
jmap --heap pid
启动
./bin/zkServer.sh start
停止
./bin/zkServer.sh stop
测试zk服务
jps
出现QuorumPeerMain或者
执行$ zkCli.sh -server centos1:2181，检查指定服务器是否成功启动。

dubbo上使用
dubbo.registry.address=zookeeper://centos1:2181?backup=10.0.30.139:2181
