Centos7安装zookeeper

1.进入/opt

cd /opt

2.下载 zookeeper-3.4.10.tar.gz：

wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.10/zookeeper-3.4.10.tar.gz

3.解压缩 zookeeper-3.4.10.tar.gz： 

tar -zxvf zookeeper-3.4.10.tar.gz

4.进入到 /opt/zookeeper-3.4.10/conf 目录中：

cd zookeeper-3.4./conf/

5.复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg：

cp zoo_sample.cfg zoo.cfg

6.用 vim 打开 zoo.cfg 文件并修改其内容为如下：

   

 # The number of milliseconds of each tick

    # zookeeper 定义的基准时间间隔，单位：毫秒

    tickTime=

    # The number of ticks that the initial

    # synchronization phase can take

    initLimit=

    # The number of ticks that can pass between

    # sending a request and getting an acknowledgement

    syncLimit=

    # the directory where the snapshot is stored.

    # do not use /tmp for storage, /tmp here is just

    # example sakes.

    # dataDir=/tmp/zookeeper

    # 数据文件夹

    dataDir=/opt/zookeeper-3.4./data

    # 日志文件夹

    dataLogDir=/opt/zookeeper-3.4./logs

    # the port at which the clients will connect

    # 客户端访问 zookeeper 的端口号

    clientPort=

    # the maximum number of client connections.

    # increase this if you need to handle more clients

    #maxClientCnxns=

    #

    # Be sure to read the maintenance section of the

    # administrator guide before turning on autopurge.

    #

    # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

    #

    # The number of snapshots to retain in dataDir

    #autopurge.snapRetainCount=

    # Purge task interval in hours

    # Set to "" to disable auto purge feature

    #autopurge.purgeInterval=

7.保存并关闭 zoo.cfg 文件:

     

8.进入到 /opt/zookeeper-3.4.10/bin 目录中：

 cd ../bin/

9.用 vim 打开 /etc/ 目录下的配置文件 profile：

    

vim /etc/profile

    并在其尾部追加如下内容：

    export ZOOKEEPER_HOME=/opt/zookeeper-3.4./

    export PATH=$ZOOKEEPER_HOME/bin:$PATH

    export PATH

10.使 /etc/ 目录下的 profile 文件即可生效：

 source /etc/profile

11.启动 zookeeper 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: /opt/zookeeper-3.4./bin/../conf/zoo.cfg

Starting zookeeper ... STARTED

12.查询 zookeeper 状态：

 zkServer.sh status

13.关闭 zookeeper 服务：  

[root@localhost bin]# zkServer.sh stop

ZooKeeper JMX enabled by default

Using config: /opt/zookeeper-3.4./bin/../conf/zoo.cfg

Stopping zookeeper ... STOPPED

14.重启 zookeeper 服务：

[root@localhost bin]# zkServer.sh restart

ZooKeeper JMX enabled by default

Using config: /opt/zookeeper-3.4./bin/../conf/zoo.cfg

ZooKeeper JMX enabled by default

Using config: /opt/zookeeper-3.4./bin/../conf/zoo.cfg

Stopping zookeeper ... no zookeeper to stop (could not find file /opt/zookeeper-3.4./data/zookeeper_server.pid)

ZooKeeper JMX enabled by default

Using config: /opt/zookeeper-3.4./bin/../conf/zoo.cfg

Starting zookeeper ... STARTED
