自行下载安装包 zookeeper-3.4.6.tar.gz

wget http://apache.fayea.com/zookeeper/zookeeper-3.4.6/zookeeper-3.4.6.tar.gz

安装步骤:

1.解压 zookeeper-3.4.6.tar.gz 到 /root 目录下

2.在目录 /root/zookeeper-3.4.6.tar.gz/conf 中新增文件 zoo.cfg

3.创建目录 /root/zookeeper-3.4.6/data

4.创建目录 /root/zookeeper-3.4.6/logs

5.执行启动命令 sh zkServer.sh start

ZooKeeper服务命令:

在准备好相应的配置之后，可以直接通过zkServer.sh 这个脚本进行服务的相关操作

1. 启动ZK服务: sh bin/zkServer.sh start
2. 查看ZK服务状态: sh bin/zkServer.sh status
3. 停止ZK服务: sh bin/zkServer.sh stop
4. 重启ZK服务: sh bin/zkServer.sh restart

设置开机启动

编辑文件: vi /etc/rc.local

追加内容: /root/zookeeper-3.4.6/bin/zkServer.sh start

提升权限:chmod +x /etc/rc.local

保存文件结束
