The system environment variables on linux do not need to be configured when installing zookeeper

1. Download the zookeeper binary installation package (you can download the attachment or download http://www.apache.org/dyn/closer.cgi/zookeeper/) from the official website

2 decompress any path on linux. This article is created under / home/hadoop/.

Tar-zxvf zookeeper-3.4.6.tar.gz

I choose zookeeper-3.4.6.tar.gz because 3.4.6 is a stable version.

3, configure zookeeper profile

Enter / home/hadoop/zookeeper-3.4.6/conf

The case configuration file for the cp zoo_sample.cfg zoo.cfg replication package is named zoo.cfg zookeeper. The default read is zoo.cfg.

The port number of dataLogDir Zookeeper snapshot file is 12888. The port number of communication between Zookeeper is 2888 by default. The port number 13888 is the election side between Zookeeper. The slogan defaults to 3888. Each cluster for Zookeeper has a leader. If the leader of one of the machines dies, the new Leader will be selected from the machine follow in the cluster. The source of server.1 server.2 server.3 forms the cluster based on the unique identity of each server in the whole cluster after server.1 server.2 server.3. If the configuration cannot be repeated, you need to execute echo "1" > myid (the first machine), echo "2" > myid (the second machine) and echo "3" > myid (the third machine) in the dataDir directory. Start sh zkServer.sh start in zookeeper execution / home/hadoop/zookeeper-3.4.6/bin to view the execution result jpsnetstat-at | grep 12181

At this point, the environment construction of zookeeper has been completed.

The next section will introduce the environment construction of kafuka.
