Tool SECURECRT

1. First download the Kafka compression pack

2. Modify the configuration file

First to have zookeeper, install zookeeper step in another essay http://www.cnblogs.com/yovela/p/5178210.html

2.1. Modify Zookeeper.properties

VI config/zookeeper.properties

Basic modification DataDir on it, the others do not change, do not remember to come back to see

2.2. Modify Server.properties

VI server.properties

Log.dirs=/usr/program/kafka/kafka_2.9.2-0.8.1.1/kafka-logs

Basically, you can change these two.

IP is the host IP and the user name is the one followed by the @ sign
