zookeeper集羣搭建
所需文件zookeeper-3.4.6.tar.gz
1. 解壓zookeeper
tar -zxvf zookeeper-3.4.6.tar.gz -C app/
cd app
mv zookeeper-3.4.6 zookeeper(重命名)
2. 修改配置文件conf/zoo.cfg
cd zookeeper/conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/home/Hadoop/appdata/zookeeper/data
dataLogDir=/home/hadoop/appdata/zookeeper/logs
clientPort=2181
Server.1=127.0.0.1:8880:7771
Server.2=127.0.0.1:8881:7772
Server.3=127.0.0.1:8882:7773
3. 創建data 、logs目錄
4. 拷貝node1下的 appdata/zookeeper文件夾分別到node2、node3
scp -r appdata/zookeeper node2:~/appdata/
scp -r appdata/zookeeper node3:~/appdata/
5. 拷貝node1下的 app/zookeeper文件夾分別到node2、node3
scp -r app/zookeeper node2:~/app/
scp -r app/zookeeper node3:~/app/
6. 分別進入node1、node2、node3下appdata/zookeeper/data
cd appdata/zookeeper/data
vi myid
分別輸入1、2、3，保存退出
7.分別進入node1、node2、node3下的zookeeper三個目錄, 啓動server
bin/zkServer.sh start
8.連接到zookeeper
bin/zkCli.sh -server node1:2181
zookeeper集羣模式搭建成功
