# 二、编写目的 #

1、了解 zookeeper 原理  
2、zookeeper 安装部署  
3、zookeeper 基本使用

# 三、环境准备 #

服务器搭建  
参考 [https://blog.csdn.net/llwy1428/article/details/111144524][https_blog.csdn.net_llwy1428_article_details_111144524] 中的  
slave1、slave2、slave3  
部分的服务器的基本配置  
必须要配置的：  
1、虚拟机安装、固定静态 IP  
2、JDK8  
3、配置防火墙  
4、配置 hosts 文件  
5、安装基本工具  
6、配置节点间免密登录  
7、集群各节点修改系统文件打开数  
8、集群各节点配置时间同步  
9、集群各节点禁用SELinux  
10、集群各节点禁用Transparent HugePages  
11、配置系统环境为UTF8

# 四、安装部署 #

1、下载安装文件

[root@slave1 ~]# wget -P https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.2-bin.tar.gz

效果如下

2、进入指定目录，查看目录结构

[root@slave1 ~]# cd /usr/bigdata/
    [root@slave1 bigdata]# ll

![在这里插入图片描述][2020122323410869.png]  
3、解压文件、查看目录

[root@slave1 bigdata]# tar zxf apache-zookeeper-3.6.2-bin.tar.gz
    [root@slave1 bigdata]# ll

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xsd3kxNDI4_size_16_color_FFFFFF_t_70 3]  
4、创建数据、日志目录

[root@slave1 ~]# mkdir -p /usr/bigdata/apache-zookeeper-3.6.2-bin/data/zk
    [root@slave1 ~]# mkdir /usr/bigdata/apache-zookeeper-3.6.2-bin/logs

5、进入配置文件目录

[root@slave1 ~]#  cd /usr/bigdata/apache-zookeeper-3.6.2-bin/conf/

6、复制配置文件

[root@slave1 conf]# cp zoo_sample.cfg zoo.cfg

7、编辑信息

dataDir=/usr/bigdata/apache-zookeeper-3.6.2-bin/data/zk
    dataLogDir=/usr/bigdata/apache-zookeeper-3.6.2-bin/logs
    server.1=slave1:2888:3888
    server.2=slave2:2888:3888
    server.3=slave3:2888:3888

8、把配置好的 zookeeper 文件发送给 slave2、slave3 节点

[root@slave1 ~]# scp -r /usr/bigdata/apache-zookeeper-3.6.2-bin root@slave2:/usr/bigdata/
    [root@slave1 ~]# scp -r /usr/bigdata/apache-zookeeper-3.6.2-bin root@slave3:/usr/bigdata/

9、配置 myid 文件

[root@slave1 ~]# vim /usr/bigdata/apache-zookeeper-3.6.2-bin/data/zk/myid
    1
    [root@slave2 ~]# vim /usr/bigdata/apache-zookeeper-3.6.2-bin/data/zk/myid
    2
    [root@slave3 ~]# vim /usr/bigdata/apache-zookeeper-3.6.2-bin/data/zk/myid
    3

10、在每个节点上启动 zkServer. 服务

[root@slave1 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start
    [root@slave2 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start
    [root@slave3 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh start

11、在每个节点上查看 zkServer. 服务的启动状态

[root@slave1 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh status
    [root@slave2 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh status
    [root@slave3 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh status

12、效果如下

13、在每个节点上关闭 zkServer 服务

[root@slave1 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh stop
    [root@slave2 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh stop
    [root@slave3 ~]# /usr/bigdata/apache-zookeeper-3.6.2-bin/bin/zkServer.sh stop

至此，Centos7.x 安装部署 Zookeeper 3.6.2 集群安装部署完毕，希望能够对您有所帮助！
