安装开发Linux组件

安装Zookeeper 3.8.x

官方网站：https://zookeeper.apache.org/

Apache ZooKeeper 社区同时支持两个发布分支：稳定版和当前版。

ZooKeeper的稳定版本是 3.8.x，当前版本是 3.9.x。一旦发布新的次要版本，稳定版本预计将很快退役，大约半年后将宣布停用。在半年的宽限期内，预计只会为该版本发布安全和关键修复。宣布 EoL 后，社区将不再提供任何补丁。所有 ZooKeeper 版本仍可从官方 Apache 档案库访问。

安装前置依赖

该组件依赖于Java环境

安装步骤

下载对应的Zookeeper 压缩包，下载链接：https://zookeeper.apache.org/releases.html

通过ssh工具上传到用户目录

[root@tutu ~]# ls
anaconda-ks.cfg                    mysql84-community-release-el9-1.noarch.rpm
apache-zookeeper-3.8.4-bin.tar.gz

#创建手动安装目录
[root@tutu ~]# mkdir /usr/local/soft
[root@tutu ~]# mv apache-zookeeper-3.8.4-bin.tar.gz /usr/local/soft/
[root@tutu ~]# cd /usr/local/soft/
[root@tutu soft]# ls
apache-zookeeper-3.8.4-bin.tar.gz

#解压压缩包
[root@tutu soft]# tar -zxvf apache-zookeeper-3.8.4-bin.tar.gz

[root@tutu soft]# ls
apache-zookeeper-3.8.4-bin  apache-zookeeper-3.8.4-bin.tar.gz

[root@tutu soft]# cd apache-zookeeper-3.8.4-bin

#创建专门存储数据的文件夹
[root@tutu apache-zookeeper-3.8.4-bin]# mkdir data

[root@tutu apache-zookeeper-3.8.4-bin]# cd conf/

[root@tutu conf]# cp -p zoo_sample.cfg zoo.cfg

#修改配置文件，修改成如下配置，dataDir路径根据自己的情况进行修改，保存退出
[root@tutu conf]# vim zoo.cfg

initLimit=10
syncLimit=5
dataDir=/usr/local/soft/apache-zookeeper-3.8.4-bin/data
clientPort=2181

#修改对应配置
[root@tutu conf]# vim /etc/profile


#合并到原配置以后如下

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
ZOOKEEPER_HOME=/usr/local/soft/apache-zookeeper-3.8.4-bin
PATH=$PATH:$JAVA_HOME/bin:$ZOOKEEPER_HOME/bin
export JAVA_HOME ZOOKEEPER_HOME CLASSPATH  PATH

#使 /etc/ 目录下的 profile 文件即可生效
[root@tutu conf]# source /etc/profile

[root@tutu conf]# zkServer.sh start
[root@tutu conf]# zkServer.sh status
[root@tutu conf]# zkServer.sh restart
[root@tutu conf]# zkServer.sh stop

#配置Systemctl管理Zookeeper
[root@tutu conf]# vim /usr/lib/systemd/system/zookeeper.service

#添加如下代码，注意安装路径

还是有图形化界面展示会更直观，目前常用的是PrettyZoo，但是2024年1月停止更新了，但已经完全够用。
