linux下安装Zookeeper 单机版

①创建安装目录

mkdir -p /usr/local/zookeeper

②将tar包解决到安装目录下

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local/zookeeper/

③创建数据目录data，日志目录log

mkdir -p /usr/local/zookeeper/apache-zookeeper-3.6.1-bin/data mkdir -p /usr/local/zookeeper/apache-zookeeper-3.6.1-bin/log

④修改配置文件(conf目录)，默认启动配置文件为zoo.cfg

（复制zoo_sample.cfg一份修改名称为zoo.cfg）

# 进入配置文件 cd /user/local/zookeeper/apache-zookeeper-3.6.1-bin/conf/ # zookeeper 启动默认加载名为 zoo.cfg的配置文件，所以复制一份命名为 zoo.cfg cp zoo_sample.cfg zoo.cfg # 修改配置文件 vim zoo.cfg

⑤配置dataDir和dataLogdir

# 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=/usr/local/zookeeper/apache-zookeeper-3.6.1-bin/data dataLogDir=/usr/local/zookeeper/apache-zookeeper-3.6.1-bin/log # 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 ## Metrics Providers

在bin目录下启动zookeeper

./zkServer.sh start

可以直接通过bin目录下的zkcli.sh进行连接

./zkCli.sh

下图为连接成功

客户端连接成功后可以进行的操作指令 ls /

集群版

创建解压目录

①先创建一个目录

mkdir -p /usr/local/zookeeper/zk1

②将文件解压到该目录

tar -zxvf apache-zookeeper-3.6.1-bin.tar.gz -C /usr/local/zookeeper/zk1/

③创建data目录和log目录，data目录下添加myid文件，myid中只写一个1就行

mkdir /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data

mkdir /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/log

cd /usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data

vim myid

复制zoo_sample.cfg，并将文件重命名为zoo.cfg

cp zoo_sample.cfg zoo.cfg

修改zk1配置的zoo.cfg

vim zoo.cfg

dataDir=/usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/data dataLogDir=/usr/local/zookeeper/zk1/apache-zookeeper-3.6.1-bin/log # 集群配置 # server.1中的1是myid文件中的内容，2888,2889,2890用于集群内部通信，3888,3889，3890用于选择leader server.1=192.168.152.100:2888:3888 server.2=192.168.152.100:2889:3889 server.3=192.168.152.100:2890:3890

将zk1文件夹复制两份为zk2/zk3

cd /usr/local/zookeeper/

cp -Rf zk1/ zk2

cp -Rf zk1/ zk3

修改zk2的配置文件zoo.cfg

dataDir=/usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/data dataLogDir=/usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/log clientPort=2182

修改zk2中data目录下的myid文件 —把1改成2

cd /usr/local/zookeeper/zk2/apache-zookeeper-3.6.1-bin/data

vim myid

把1改成2 (同理在zk3中把myid改成3)

注意:这里的myid和配置文件中有关

如果没有改可能会出现以下错误

修改zk3的配置文件zoo.cfg（和zk2相似）

dataDir=/usr/local/zookeeper/zk3/apache-zookeeper-3.6.1-bin/data dataLogDir=/usr/local/zookeeper/zk3/apache-zookeeper-3.6.1-bin/log clientPort=2183

启动

注意：这里需要把三台**全部启动，再查看状态**

原因：涉及到Leader（Master）选举的问题 cd /usr/local/zookeeper/ zk1/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start zk2/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start zk3/apache-zookeeper-3.6.1-bin/bin/zkServer.sh start

查看状态

cd /usr/local/zookeeper/ zk1/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status zk2/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status zk3/apache-zookeeper-3.6.1-bin/bin/zkServer.sh status
