Then download the latest stable version to the/OPT directory

/opt$ wget http://mirrors.cnnic.cn/apache/zookeeper/stable/zookeeper-3.4.6.tar.gz

Unzip directory:

The directory structure after decompression is:

/opt/zookeeper-3.4.6$ tree-l 1.├──bin├──build.xml├──changes.txt├──conf├──contrib├──dist-maven├──docs├──ivysettin gs.xml├──ivy.xml├──lib├──license.txt├──notice.txt├──readme_packaging.txt├──readme.txt├──recipes├──src├── Zookeeper-3.4.6.jar├──zookeeper-3.4.6.jar.asc├──zookeeper-3.4.6.jar.md5└──zookeeper-3.4.6.jar.sha1

Go to the Conf directory and copy the sample configuration file

CD conf/$ CP zoo_sample.cfg zoo.cfg

Edit the Zoo.cfg file, modify the Data directory path, and the annotations explain the role of each parameter:

# The number of milliseconds of each tickticktime=2000# the number of ticks, the initial # synchronization phase can T akeinitlimit=10# the number of ticks so can pass between # Sending a request and getting an acknowledgementsynclimit=5# The directory where the snapshot is stored.# does not use/tmp for storage,/tmp here is just # example sakes.datadir=/opt/z k_data# the port at which the clients would connectclientport=2181

Create a Directory

Mkdir/opt/zk_data
