搭建Zookeeper叢集

一、環境要求
- OS:Centos6.x
- JDK: 1.8
- 防火牆:關閉
二、下載Zookeeper
wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz
三、安裝並配置
1. 新建目錄
mkdir -p /data/zookeeper mkdir -p /data/log/zookeeper
2. 解壓zookeeper
tar -zxvf zookeeper-3.4.10.tar.gz
3. 修改配置
ln -s zookeeper-3.4.10 zookeeper
cd zookeeper/conf/
3.1 修改配置
cp zoo_sample.cfg zoo.cfg vim zoo.cfg
# The number of milliseconds of each tick tickTime=2000 # The number of ticks that the initial # synchronization phase can take initLimit=10 # The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=/data/zookeeper dataLogDir=/data/log/zookeeper # the port at which the clients will connect clientPort=2181 # the maximum number of client connections. # increase this if you need to handle more clients #maxClientCnxns=60 # # Be sure to read the maintenance section of the # administrator guide before turning on autopurge. # # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance # # The number of snapshots to retain in dataDir #autopurge.snapRetainCount=3 # Purge task interval in hours # Set to "0" to disable auto purge feature #autopurge.purgeInterval=1 server.1=node1:2888:3888 server.2=node2:2888:3888 server.3=node3:2888:3888
3.2 分發配置到其它機器
scp zoo.cfg [email protected]:~/zookeeper/conf/ scp zoo.cfg [email protected]:~/zookeeper/conf/
3.3 根據server.1
、server.2
、server.3
的值,在這三臺機器上建立myid
touch /data/zookeeper/myid
在node1的機器上執行:
echo "1" > /data/zookeeper/myid
在node2的機器上執行:
echo "2" > /data/zookeeper/myid
在node3的機器上執行:
echo "3" > /data/zookeeper/myid
執行完畢後,node1的myid值為1,node2的myid值為2,node3的myid值為3.
4. 啟動zookeeper
bin/zkServer.sh start
並且檢視狀態
bin/zkServer.sh status
