Install zookeeper

1. Unzip the zookeeper installation package

2. Configure environment variables

Go to etc and modify the profile file

vim /etc/profile

Add the following:

export ZOOKEEPER_HOME=/home/liyuan168/mytool/zookeeper-3.3.6

export PATH=$PATH:$JAVA_HOME/bin :$ZOOKEEPER_HOME/bin:$PATH

Reload the configuration file.

source /etc/profile

3. Configure the configuration file

1. tickTime= 2000    
2. dataDir=/Users/apple/zookeeper/data    
3. dataLogDir=/Users/apple/zookeeper/logs    
4. clientPort=4180 

• ickTime: The basic time unit used in zookeeper, in milliseconds.
• dataDir: The data directory. Can be any directory.
• dataLogDir: log directory, which can also be any directory. If this parameter is not set, the same settings as dataDir will be used.
• clientPort: The port number that listens for client connections. The address port registered by the producer

So far, the stand-alone mode of zookeeper has been configured. To start the server, just run the script:

ZooKeeper service command:

     After preparing the corresponding configuration, you can directly use the zkServer.sh script to perform service-related operations

• 1. Start the ZK service: sh bin/zkServer.sh start
• 2. Check the ZK service status: sh bin/zkServer.sh status
• 3. Stop the ZK service: sh bin/zkServer.sh stop
• 4. Restart the ZK service: sh bin/zkServer.sh restart

If you have configured the environment variables, you can use the zookeeper command from any location without entering the bin directory. Such as:  zkServer.sh start. Execute this command directly to start zookeeper
