linux 系统下 zookeeper 安装教程

1.下载安装包

  1)进入安装目录

  cd /home/install/

  2)下载

  wget http://mirror.bit.edu.cn/apache/zookeeper/stable/zookeeper-3.4.12.tar.gz

  

2.安装

  1)创建和解压至安装目录

  mkdir /usr/local/zookeeper

  tar -zxcf /home/install/zookeeper-3.4.12.tar.gz -C /usr/local/zookeeper/

  2)拷贝样本配置为主配置

     进入配置目录,赋值拷贝样本文件

    cd /usr/local/zookeeper/zookeeper-3.4.12/conf/

    cp zoo_sample.cfg zoo.cfg

    

  3)简单修改配置

    创建数据存储目录与日志目录

    mkdir /usr/local/zookeeper/zookeeper-3.4.12/dataDir

    mkdir /usr/local/zookeeper/zookeeper-3.4.12/dataLogDir

    修改数据存储和日志目录

    vim /usr/local/zookeeper/zookeeper-3.4.12/conf/zoo.cfg

      

3.配置zookeeper环境变量

  1)依赖JVM环境,所以JVM与zookeeper环境变量都要配置

    vim /etc/profile

    在尾部加入或修改以下

JAVA_HOME=/usr/local/java/jdk1.8.0_181
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME PATH
ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.4.12
PATH=$PATH:$ZOOKEEPER_HOME/bin
export PATH ZOOKEEPER_HOME PATH

    

  2)生效

    source /etc/profile

3.测试

  1)启动

     /usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh start

  2)连接

    /usr/local/zookeeper/zookeeper-3.4.12/bin/zkCli.sh

  3)增删改查

    

  4)其他

    help查看指令帮助

    

4.开机启动

  (1)编辑zookeeper.service文件

    vim /usr/lib/systemd/system/zookeeper.service 

    加入如下内容

[Unit]
Description=zookeeper
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
ExecStart=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh start
ExecReload=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh restart
ExecStop=/usr/local/zookeeper/zookeeper-3.4.12/bin/zkServer.sh stop
[Install]
WantedBy=multi-user.target

  (2)生效

    systemctl daemon-reload

  (3)改变文件权限

    chmod 777 /usr/lib/systemd/system/zookeeper.service

  (4)systemctl开机启动zookeeper

    systemctl enable /usr/lib/systemd/system/zookeeper.service

    或

    systemctl enable /usr/lib/systemd/system/zookeeper

  (5)查看是否开机启动

    systemctl is-enabled zookeeper.service

  (6)systemctl取消开机启动redis

    systemctl disable zookeeper.service
