centos7-安装包方式安装zookeeper

基础环境

---

centos7.5 + zookeeper-3.4.6

步骤

---

1. 下载zookeeper-3.4.6.tar.gz

2. 解压缩到自己项目目录

   tar -zxvf zookeeper-3.4.6.tar.gz
   mv zookeeper-3.4.6 /usr/local/services/zookeeper  #更改为自己的项目目录
   

3. 配置启动文件

   cd /usr/local/services/zookeeper/conf
   cp zoo_sample.cfg zoo.cfg     #复制配置样本到我们自己的配置文件
   
   vim zoo.cfg
   
   >>>
       # zookeeper 定义的基准时间间隔，单位：毫秒
       tickTime=2000
       # The number of ticks that the initial
       # synchronization phase can take
       initLimit=10
       # The number of ticks that can pass between
       # sending a request and getting an acknowledgement
       syncLimit=5
       # 数据文件夹
       dataDir=/usr/local/services/zookeeper/data
       # 日志文件夹
       dataLogDir=/usr/local/services/zookeeper/logs	   #要手动创建这个文件夹，否则会出错
       # 客户端访问 zookeeper 的端口号
       clientPort=2181
   

4. 配置环境变量

   vim /etc/profile
   
   >>>>追加
       export ZOOKEEPER_HOME=/usr/local/services/zookeeper/
       export PATH=$ZOOKEEPER_HOME/bin:$PATH
       export PATH
   
   # 使文件生效
   source /etc/profile
   

5. 启动服务

   zkServer.sh start
   
   如打印如下信息则表明启动成功：
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/bin/../conf/zoo.cfg
   Starting zookeeper ... STARTED
   

6. 查看服务状态

   zkServer.sh status
   

7. 关闭服务

   zkServer.sh stop
   
   如打印如下信息则表明成功关闭：
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Stopping zookeeper ... STOPPED
   

8. 重启服务

   zkServer.sh restart
   
   如打印如下信息则表明重启成功：
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Stopping zookeeper ... STOPPED
   ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Starting zookeeper ... STARTED
