11. Kafka

This topic describes the installation, configuration, and basic use of Kafka.

Kafka basic Information

Official website: http://kafka.apache.org/11.1. Environment preparation # switch to workspace cd / opt/workspaces# to create Kafka data directory mkdir data/kafka# create Kafka log directory mkdir logs/kafka11.2. Install wget http://mirrors.cnnic.cn/apache/kafka/0.8.2.2/kafka_2.10-0.8.2.2.tgztar-zxf kafka_2.10-0.8.2.2.tgzrm-rf kafka_2.10-0.8.2.2.tgzmv kafka_2.10-0.8.2.2. / frameworks/kafka11.3. Configuration (pseudo-distributed)

Vi. / frameworks/kafka/config/server.properties

# set the following parameters: broker.id=0port=9092# external hostname advertised.host.name=# data directory log.dirs=/opt/workspaces/data/kafka# connection ZKzookeeper.connect=localhost:2181

When you have multiple network cards or use special network settings to cause the IP used when Kafka starts to differ from the exposed IP, you need to specify advertised.host.name as the public network IP you expect to use.

Log.dirs is interpreted as A comma seperated list of directories under which to store log files. Here, the so-called log file refers to the message persistence file of Kafka, not the run log in the general sense.

Vi. / frameworks/kafka/config/log4j.properties

# set the log directory kafka.logs.dir=/opt/workspaces/logs/kafka11.4. Start and stop nohup. / frameworks/kafka/bin/kafka-server-start.sh. / frameworks/kafka/config/server.properties > / dev/null 2 > & 1 & 11.5.
