As can be seen from the following part, after selecting a Leader, the cluster finally stabilized. Therefore, the exceptions in the front part of the above log can be ignored. The first one cannot be connected to the later one. config/zookeeper.propertie #Note that this is the front desk startĪt the beginning, an error will be reported because when the zookeeper cluster is started, each node tries to connect to other nodes in the cluster. Start zookpeer cluster /opt/kafka_2.12-2.7.0/bin/zookeeper-server-start.sh. mkdir -p /data/zookeeperĮcho (1，2,3) > /data/zookeeper/myid #Daily ip correspondence, no repetition Port 3888: it means that in case the Leader server in the cluster hangs up, a port is needed to re elect and select a new Leader, and this port is used to communicate with each other during the election. Vim /opt/kafka./config/zookeeper.propertie tickTime=2000Ģ888 port: refers to the port where this server exchanges information with the Leader server in the cluster Use the zookeeper that comes with kafka bagĪdd the following basic configuration (basically the same on the three machines) Kafka startup depends on the zookeeper cluster 1).

The download address of the official website is: Unzip the downloaded package Start filebeat -e -c /etc/filebeat/filebeat.ymlĢ, Build and test kafka cluster 1. Topic: node01-system-message #The topic will be created in kafka for reading by logstash subscription
Configure filebeat cat /etc/filebeat/filebeat.yml You can directly install the rpm package and see the linux version 2. Install filebeat yum -y install filebeat.rpm It should be noted that the logs processed by logstash are in json format Architecture diagram:ġ, Configure filebeat 1. Be responsible for the log processing from kafka, and then spit the processed log to elastic search. During deployment, zookeeper should be installed separately on each kafka node, and ensure that zookeeper can communicate with each other (port 2181).Ĥ.Logstash is the log processor and the core of the whole elk system. It is responsible for maintaining the load balance of the whole kafka cluster. Its main function is to cache between filebeat and logstash to avoid data loss due to too much data written to logstash.ģ.Zookeeper is kafka's distribution system. When the log file changes, it spits the file content to kafka.Ģ.Kafka is a message queue. 1.Filebeat is responsible for capturing data from the web server in real time. Filebeat is a lightweight shipper that enables you to send your Apache Kafka message queue logs to Logstash and Elasticsearch.
