1：配置java环境
修改/etc/bashrc文件，添加JAVA_HOME
cat /etc/bashrc
export JAVA_HOME=/root/jdk-11.0.16.1
export PATH=$PATH:$JAVA_HOME/bin:.
2：下载zookeeper
https://dlcdn.apache.org/zookeeper/zookeeper-3.7.1/apache-zookeeper-3.7.1-bin.tar.gz
这个是3.7.1版本的下载地址
3：zookeeper进行解压缩
tar zxvf apache-zookeeper-3.7.1-bin.tar.gz
4: 修改配置文件zoo.cfg
zoo.cfg在apache-zookeeper-3.7.1-bin/conf目录下。
进入zookeeper目录，将conf目录下的zoo_sample.cfg文件复制为zoo.cfg，并修改配置：
cd zookeeper/conf
cp zoo_sample.cfg zoo.cfg
vi zoo.cfg
添加以下配置：
[kfk@bigdata-pro01 conf]$ cat 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 anacknowledgement
syncLimit=5
# the directory where the snapshot isstored.
# do not use /tmp for storage, /tmp here isjust
# example sakes.
dataDir=/home/kfk/apache-zookeeper-3.7.1-bin/data
# the port at which the clients willconnect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle moreclients
#maxClientCnxns=0
#
# Be sure to read the maintenance sectionof the
# administrator guide before turning onautopurge.
#
#http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain indataDir
#autopurge.snapRetainCount=20
# Purge task interval in hours
# Set to "0" to disable autopurge feature
#autopurge.purgeInterval=48
## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true
server.1=bigdata-pro01:2888:3888
server.2=bigdata-pro02:2888:3888
server.3=bigdata-pro03:2888:3888
server.4=bigdata-pro04:2888:3888
server.5=bigdata-pro05:2888:3888
zookeeper.session.timeout.ms=40000000
其中dataDir 指向的目录容量尽量大。
maxClientCnxns=0 #为 0 或者忽略取消对并发连接的限制
autopurge.snapRetainCount=20 #保存最新的20个日志文件
autopurge.purgeInterval=48 #保存日志文件48小时
5:配置myid文件
/home/kfk/apache-zookeeper-3.7.1-bin/data/myid
不同的服务器使用不通的myid。
我是从1进行递增的
6：进行试启动
bin/zkServer.sh start
7： 检查进程是否启动
ps -ef|grep zookeeper
如果能查到进程，那么恭喜你，启动成功了。

[kfk@bigdata-pro01 ~]$
8：将配置好的zooker进行打包
tar cvf apache-zookeeper-3.7.1-bin.tarapache-zookeeper-3.7.1-bin
9：将压缩包分发到集群中的主机
scp apache-zookeeper-3.7.1-bin.tarkfk@bigdata-pro02:/home/kfk/
scp apache-zookeeper-3.7.1-bin.tarkfk@bigdata-pro03:/home/kfk/
scp apache-zookeeper-3.7.1-bin.tarkfk@bigdata-pro04:/home/kfk
scp apache-zookeeper-3.7.1-bin.tarkfk@bigdata-pro05:/home/kfk/
我这次是配置了5台主机。
10：在其他主机解压缩
tar xvf apache-zookeeper-3.7.1-bin.tar
11：修改其他主机myid
修改myid文件
12：启动其他主机的zookeeper
启动 bin/zkServer.sh start
13：客户端连接
bin/zkCli.sh -server127.0.0.1:2181
这使您可以执行简单的类似文件的操作。
连接后，您应该会看到类似以下内容：
在 shell 中，键入以获取可从客户端执行的命令列表，如下所示：help
ZooKeeper -server host:port-client-configuration properties-file cmd args
addWatch [-m mode] path # optional mode is one of [PERSISTENT,PERSISTENT_RECURSIVE] - default is PERSISTENT_RECURSIVE
addauth scheme auth

create [-s] [-e] [-c] [-t ttl] path [data] [acl]
delete [-v version] path

delquota [-n|-b|-N|-B] path
get [-s] [-w] path

Command not found: Command not found help
从这里，您可以尝试一些简单的命令来感受这个简单的命令行界面。首先，首先发出 list 命令，如 中所示，结果为：ls
[zk: 127.0.0.1:2181(CONNECTED) 1] ls
ls [-s] [-w] [-R] path
[zk: 127.0.0.1:2181(CONNECTED) 2] ls /
[admin, brokers, cluster, config,consumers, controller, controller_epoch, feature, isr_change_notification,latest_producer_id_block, log_dir_event
接下来，通过运行 来创建新的 znode。这将创建一个新的 znode 并将字符串 “my_data” 与节点关联。您应该看到：create
/zk_test my_data
[zk: 127.0.0.1:2181(CONNECTED) 3] create/zk_test my_data
Created /zk_test
[zk: 127.0.0.1:2181(CONNECTED) 4]
发出另一个命令以查看目录的外观：ls
/
[admin, brokers, cluster, config,consumers, controller, controller_epoch, feature, isr_change_notification,latest_producer_id_block, log_dir_event_notification, zk_test, zookeeper]
请注意，zk_test目录现已创建。
接下来，通过运行命令验证数据是否与 znode 关联，如下所示：get
[zk: 127.0.0.1:2181(CONNECTED) 0] get/zk_test
my_data
[zk: 127.0.0.1:2181(CONNECTED) 1]
[zk: 127.0.0.1:2181(CONNECTED) 3] set/zk_test jkjunk
[zk: 127.0.0.1:2181(CONNECTED) 4] get/zk_test
jkjunk
[zk: 127.0.0.1:2181(CONNECTED) 5]
（请注意，我们在设置数据后做了一个，它确实发生了变化。Get
最后，让我们通过发出以下命令来发布节点：delete
[zk: 127.0.0.1:2181(CONNECTED) 6] ls /
[admin, brokers, cluster, config,consumers, controller, controller_epoch, feature, isr_change_notification,latest_producer_id_block, log_dir_event_notification, zookeeper]
