阿里云 Centos7 安装zookeeper

1、创建 /usr/local/zookeeper 文件夹

shell>mkdir -p /usr/local/zookeeper

2、进入到 /usr/local/zookeeper 目录中

shell>cd /usr/local/zookeeper

3、.进入zookeeper官网找到下载镜像连接

https://zookeeper.apache.org/

https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/

下载zookeeper-3.5.4-beta.tar.gz

shell> wget  htps://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.5.4-beta/zookeeper-3.5.4-beta.tar.gz

4、解压缩 zookeeper-3.5.4-beta.tar.gz

shell>tar -zxvf zookeeper-3.5.3-beta.tar.gz

5、配置文件夹

文件移至/usr/local/zookeeper/下

shell>mv /usr/local/webtools/zookeeper-3.5.4-beta /usr/local/zookeeper/

进入到 /usr/local/zookeeper/zookeeper-3.5.4-beta/conf 目录中

shell>cd zookeeper-3.5.4-beta/conf/

复制 zoo_sample.cfg 文件的并命名为为 zoo.cfg

shell>cp zoo_sample.cfg zoo.cfg

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=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
    # 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=/usr/local/zookeeper/zookeeper-3.5.3-beta/data
 
    # 日志文件夹
    dataLogDir=/usr/local/zookeeper/zookeeper-3.5.3-beta/logs
 
    # the port at which the clients will connect
    # 客户端访问 zookeeper 的端口号
    clientPort=2181
 
    # the maximum number of client connections.
    # increase this if you need to handle more clients
    #maxClientCnxns=60
    #
    # 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=3
    # Purge task interval in hours
    # Set to "0" to disable auto purge feature
    #autopurge.purgeInterval=1

保存并关闭 zoo.cfg 文件

用 vim 打开 /etc/ 目录下的配置文件 profile并在其尾部追加如下内容

shell>vim /etc/profile

export ZOOKEEPER_HOME=/usr/local/zookeeper/zookeeper-3.5.4-beta
export PATH=$ZOOKEEPER_HOME/bin:$PATH
export PATH

使 /etc/ 目录下的 profile 文件即可生效：source /etc/profile

6、操作命令

shell>zkServer.sh start

启动 zookeeper 服务如打印如下信息则表明启动成功:

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

shell>zkServer.sh status

查询 zookeeper 状态

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone

shell>zkServer.sh stop

关闭 zookeeper 服务如打印如下信息则表明成功关闭：

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED

shell>zkServer.sh restart

重启 zookeeper 服务如打印如下信息则表明重启成功：

ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Stopping zookeeper ... no zookeeper to stop (could not find file /usr/local/zookeeper/zookeeper-3.5.4-beta/data/zookeeper_server.pid)
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.5.4-beta/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
