一、Installation Zookeeper-3.7.1 on openEuler
地址
是下载哪个文件呢！！！
1 下载
mkdir /opt/software && cd /opt/software
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.7.1/apache-zookeeper-3.7.1-bin.tar.gz2 解压
tar -zxvf /opt/software/apache-zookeeper-3.7.1-bin.tar.gz -C /opt/ && cd /opt/apache-zookeeper-3.7.1-bin/bin && ls
mv /opt/apache-zookeeper-3.7.1-bin /opt/zookeeper-371 && cd /opt/zookeeper-371 && ll

将zookeeper/conf路径下的zoo_sample.cfg修改为zoo.cfg
cd /opt/zookeeper-371/conf && cp /opt/zookeeper-371/conf/zoo_sample.cfg /opt/zookeeper-371/conf/zoo.cfg && ll
4 修改 zoo.cfg
打开zoo.cfg配置文件，修改dataDir路径
vim /opt/zookeeper-371/conf/zoo.cfg
## 心跳检查的时间 2秒
tickTime=2000
## 初始化时 连接到服务器端的间隔次数，总时间10*2=20秒
initLimit=10
## ZK Leader 和follower 之间通讯的次数，总时间5*2=10秒
syncLimit=5
## 存储内存中数据快照的位置，如果不设置参数，更新事务日志将被存储到默认位置。
dataDir=/opt/zookeeper-371/zkData
## ZK 服务器端的监听端口
clientPort=2181
## ZK 端口号，默认8080
admin.serverPort=90915 创建zkData文件夹
mkdir /opt/zookeeper-371/zkData6 日志目录[自动生成]
ll /opt/zookeeper-371/logs/7 启动 Zookeeper
[root@ecs-65685 ~]# /opt/zookeeper-371/bin/zkServer.sh
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper-371/bin/../conf/zoo.cfg
Usage: /opt/zookeeper-371/bin/zkServer.sh [--config <conf-dir>] {start|start-foreground|stop|version|restart|status|print-cmd}
## 启动
/opt/zookeeper-371/bin/zkServer.sh start
## 状态
/opt/zookeeper-371/bin/zkServer.sh status
## 前台启动
/opt/zookeeper-371/bin/zkServer.sh start-foreground
8 查看进程是否启动
[root@ecs-65685 ~]# jps
2530 WrapperSimpleApp
9667 QuorumPeerMain
9814 Jps9 配置环境变量
vim /etc/profile
export PATH=$PATH:/opt/zookeeper-371/bin
## 配置立即生效
source /etc/profile
二、Zookeeper 客户端常用功能
1 连接 & 退出
## 连接本机直接输入
/opt/zookeeper-371/bin/zkCli.sh
## 连接zookeeper客户端
/opt/zookeeper-371/bin/zkCli.sh -server 127.0.0.1:2181
## 退出zookeeper客户端
quit2 操作命令
## 查看 Zookeeper所有命令
help
## 查看根目录下包含的节点
ls /
## 查看节点状态信息
ls -s /
X、One Step Success
Y、Error message
1 Starting zookeeper ... FAILED TO STAR
zookeeper文件下载错了
2 端口8080已绑定
Caused by: java.io.IOException: Failed to bind to /0.0.0.0:8080
vim /opt/zookeeper-371/conf/zoo.cfg
## 修改端口号
admin.serverPort=9091报错信息
[root@ecs-65685 ~]# tail -n 100 -f /opt/zookeeper-371/logs/zookeeper-root-server-ecs-65685.out
