4.3.1 下載解壓 mkdir -p /data/packages/ cd /data/packages/ wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz cd /usr/local/ tar -zxvf /data/packages/zookeeper-3.4.10.tar.gz ln -s zookeeper-3.4.10 zookeeper cd zookeeper mkdir data log cd conf/ cp zoo_sample.cfg zoo.cfg 4.3.2 修改配置文件 vim zoo.cfg

4.3.5 啟動zookeeper cd /usr/local/zookeeper/bin/ ./zkServer.sh start
4.4 安裝Mycat 同樣，3個節點都需要安裝mycat。
cd /data/packages/ wget http://dl.mycat.io/1.6-RELEASE/Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz cd /usr/local/ tar -zxvf /data/packages/Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz 4.6 執行mycat初始化數據 3個節點Mycat都執行如下腳本
sh /usr/local/mycat/bin/init_zk_data.sh 4.7 配置mycat支持zookeeper vim /usr/local/mycat/conf/myid.properties
loadZk=true # zk集群地址，多個用","隔開 zkURL=127.0.0.1:2181 # zk集群內Mycat集群ID clusterId=mycat-cluster-1 # Mycat集群內本實例ID，禁止重復 myid=mycat_fz_01 # Mycat集群內節點個數 clusterSize=3 clusterNodes=mycat_fz_01,mycat_fz_02,mycat_fz_03 #server booster ; booster install on db same server,will reset all minCon to 1 type=server boosterDataHosts=dataHost1 4.8 用zookeeper配置mycat 使用ZooInspector工具管理ZooKeeper，以下是連接zookeeper方法。
