Centos7部署Zookeeper单节点

2022-12-09 19:52:08

1、安装准备好一个虚拟机（vmware、VirtualBox）。

2、使用连接工具进行连接（Xshell、electerm等工具，我使用的electerm工具）。

使用

ip address

或

ip addr

来查看虚拟机地址，如果使用的是局域网内的需要设置桥接网络，复制物理地址，如果是本机开的虚拟机则不需要。

使用连接工具进行连接（electerm）

如果你看到了，如下的界面就表示连接成功了。

3、下载zookeeper

zookeeper官方下载地址

我这里下载的zookeeper的3.6.3，连接如下

apache-zookeeper-3.6.3

4、构建环境

切换到opt目录

cd /opt

创建modules目录和software目录（父子关系，也可以不创建直接保存到opt中，我是做了个分类）。

mkdir -p /opt/modules/software

查看是否创建成功（如果未创建本步骤可以省略）

ls

5、上传zookeeper文件

 6、解压zookeeper压缩包

切换到software

cd ./modules/software

查看zookeeper压缩包是否存在

ls

如果不存在，可能是上传到别的路径或者是上传失败了。

解压zookeeper压缩文件到/opt/modules

tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz -C /opt/modules/

如果没有任何错误，则表示解压成功了。

7、部署与运行

切换到zookeeper的安装路径

cd /opt/modules

修改zookeeper文件的名称（名称太长了，不容易操作，可以不修改）

mv apache-zookeeper-3.6.3-bin/ zookeeper3.6.3

切换到zookeeper的配置目录中

cd zookeeper3.6.3/conf/

创建一个data文件夹

mkdir /opt/modules/zookeeper3.6.3/data

复制一份zoo_sample.cfg配置文件并且修改其名称为zoo_cfg

cp zoo_sample.cfg zoo.cfg

修改zoo_cfg配置

vi zoo.cfg

或

vim zoo.cfg

如果使用vim报centos vim command not found，可以尝试安装一下vim

yum install -y vim

再进行编辑

修改的配置（可选，也可以保持默认值）

tickTime = 2000
# zookeeper的数据保存位置（推荐修改）
dataDir = /opt/zookeeper3.6.3/data
clientPort = 2181
initLimit = 5
syncLimit = 2

如果当前目录就是zookeeper安装目录，则可以使用

pwd

获取后进行修改

按下ESC -> 在英文或者半角状态下按下Shift+:键，输入wq! 退出编辑。

运行zookeeper

/opt/modules/zookeeper3.6.3/bin/zkServer.sh start

如果看到如下的结果表示运行成功了

 通过zkCli来进行连接测试

/opt/modules/zookeeper3.6.3/bin/zkCli.sh

会有如下字符输出

恭喜你，zookeeper单节点部署成功了。

如何停止zookeeper单节点服务呢？

退出zkCli

quit

停止zookeeper服务

/opt/modules/zookeeper3.6.3/bin/zkServer.sh stop

如果看到了如下的结果表示停止成功了。
