搭建Zookeeper
一 准备三台服务器（本人Centos7虚拟机）
AMouse: 192.168.3.201
BCattle: 192.168.3.202
Ctiger: 192.168.3.203
二 下载Zookeeper
版本： zookeeper-3.4.6 地址： http://mirror.bit.edu.cn/apache/zookeeper/ 地址： https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/
三 上传文件到/usr/local/ 目录下，解压至当前目录，并将zookeeper-3.4.6修改为为 zookeeper
tar -zxvf zookeeper-3.4.6.tar.gz -C /usr/local/
mv zookeeper-3.4.6 zookeeper
四 在zookeeper目录下建立data和 logs目录
mkdir /usr/local/zookeeper/data
mkdir /usr/local/zookeeper/logs
五 将zookeeper目录下/usr/local/zookeeper/conf/zoo_simple.cfg文件修改为 zoo.cfg
cd /usr/local/zookeeper/conf
mv zoo_sample.cfg zoo.cfg
六 修改zoo.cfg 文件
vi zoo.cfg
红色标记位置是需要修改的配置
1 # The number of milliseconds of each tick 2 tickTime=2000 3 # The number of ticks that the initial 4 # synchronization phase can take 5 initLimit=10 6 # The number of ticks that can pass between 7 # sending a request and getting an acknowledgement 8 syncLimit=5 9 # the directory where the snapshot is stored. 10 # do not use /tmp for storage, /tmp here is just 11 # example sakes. 12 dataDir=/usr/local/zookeeper/data 13 # the port at which the clients will connect 14 clientPort=2181 15 # the maximum number of client connections. 16 # increase this if you need to handle more clients 17 #maxClientCnxns=60 18 # 19 # Be sure to read the maintenance section of the 20 # administrator guide before turning on autopurge. 21 # 22 # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance 23 # 24 # The number of snapshots to retain in dataDir 25 #autopurge.snapRetainCount=3 26 # Purge task interval in hours 27 # Set to "0" to disable auto purge feature 28 #autopurge.purgeInterval=1 29 30 dataLogDir=/usr/local/zookeeper/logs 31 32 server.1=192.168.3.201:2888:3888 33 34 server.2=192.168.3.202:2888:3888 35 36 server.3=192.168.3.203:2888:3888
七 拷贝zookeeper目录到另外两台服务器
scp -r /usr/local/zookeeper root@192.168.3.202:/usr/local/ scp -r /usr/local/zookeeper root@192.168.3.203:/usr/local/
八 在三台服务器上分别创建myid文件
server.1 的myid内容为1
192.168.3.201
echo "1">> /usr/local/zookeeper/data/myid
server.2的myid内容为2
192.168.3.202
echo "2">> /usr/local/zookeeper/data/myid
server.3的myid为 3
192.168.3.203
echo "3">> /usr/local/zookeeper/data/myid
九 在三台服务器上分别启动ZooKeeper服务
cd /usr/local/zookeeper/ bin/zkServer.sh start
十 ZooKeeper集群的状态
bin/zkServer.sh status
