linux 安装zookeeper

3.4 linux 安装zookeeper

下载zookeeper安装包

https://downloads.apache.org/zookeeper/zookeeper-3.5.9/

 

上传zookeeper 的安装包到Linux 服务器上面

 # 上传到 /myapp  下
 /myapp

 

解压apache-zookeeper-3.5.9-bin.tar.gz

  tar -zxvf apache-zookeeper-3.5.9-bin.tar.gz 

 

把解压后的文件移动到指定位置, 这里统一移动到 /myapp/software 目录下

  mv apache-zookeeper-3.5.9-bin /myapp/software/

 

在 /data 目录下创建一个文件夹 zookeeper 用来存放zookeeper 的数据文件

 cd /data
 mkdir zookeeper

 

复制cp zoo_sample.cfg zoo.cfg

 #进入 /myapp/software/apache-zookeeper-3.5.9-bin/conf 目录
 cd /myapp/software/apache-zookeeper-3.5.9-bin/conf
 # 复制 zoo_sample.cfg 文件,并重命名为zoo.cfg 否则zookeeper不会生效
 cp zoo_sample.cfg zoo.cfg

 

编辑 zoo.cfg 文件,

修改 dataDir 属性等于 /tmp/zookeeper 如下第13行所示

 # The number of milliseconds of each tick
 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.
 # 主要是这里<>
 dataDir=/tmp/zookeeper
 # the port at which the clients will connect
 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
 ​
