1. Create /usr/local/services/zookeeper folder:


  mkdir -p /usr/local/services/zookeeper

2, into the/usr/local services/zookeeper directory:


  cd /usr/local/services/zookeeper

3. Download ES15en-3.4.9.tar.gz:


 wget https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.4.9/zookeeper-3.4.9.tar.gz

4. Unzip zookeeper-3.4.9.ES22en.gz:


  tar -zxvf zookeeper-3.4.9.tar.gz

5, enter/usr local/services/zookeeper/zookeeper 3.4.9 / conf directory:


cd zookeeper-3.4.9/conf/

6. Copy the file es36EN_ES37en. cfg and name it zoo. cfg:


cp zoo_sample.cfg zoo.cfg

7. Open the file zoo.cfg with vim and modify its contents as follows:


# The number of milliseconds of each tick
    # zookeeper  The defined base time interval, in milliseconds 
  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
   #  Data folder 
  dataDir=/usr/local/services/zookeeper/zookeeper-3.4.9/data
   #  Log folder 
  dataLogDir=/usr/local/services/zookeeper/zookeeper-3.4.9/logs
   # the port at which the clients will connect
   #  Client access  zookeeper  The port number 
  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

8. Save and close the zoo. cfg file:

9, into the/usr/local/services/zookeeper/zookeeper 3.4.9 / bin directory:

cd ../bin/

10. Use vim to open the configuration file profile in /etc/ directory:

vim /etc/profile

And appends the following to its tail:


 # idea - zookeeper-3.4.9 config start - 2016-09-08
   export ZOOKEEPER_HOME=/usr/local/services/zookeeper/zookeeper-3.4.9/
   export PATH=$ZOOKEEPER_HOME/bin:$PATH
   export PATH
   # idea - zookeeper-3.4.9 config start - 2016-09-08

11. Make the profile file in /etc/ directory effective:


 source /etc/profile

12. Start zookeeper Service:


zkServer.sh start

If the following information is printed, it indicates successful startup:


  cd /usr/local/services/zookeeper

13. Query zookeeper status:


  cd /usr/local/services/zookeeper

14. Shut down zookeeper service:


  cd /usr/local/services/zookeeper

Successful shutdown is indicated if the following information is printed:


 ZooKeeper JMX enabled by default
   Using config: /usr/local/services/zookeeper/zookeeper-3.4.9/bin/../conf/zoo.cfg
   Stopping zookeeper ... STOPPED

15. Restart zookeeper service:


  cd /usr/local/services/zookeeper

A successful restart is indicated by printing the following information:


  cd /usr/local/services/zookeeper
