1. KAFKA下載地址:http://kafka.apache.org/downloadsnode
KAFKA-快速上手-官方網站:http://kafka.apache.org/quickstartlinux
2. 下載完成後解壓,修改config目錄下的配置文件:server.properties 、zookeeper.properties
apache
1)修改server.properties:bootstrap
------------------------------------------------- Server Basics -------------------------------------------------vim
設置broker.id,確保每一個broker的id是惟一的,能夠默認master節點的爲0,其餘依次爲一、2...服務器
------------------------------------------------- Socket Server Settings -------------------------------------------------測試
設置listeners,listeners = PLAINTEXT://172.16.106.153:9092fetch
------------------------------------------------- Log Basics -------------------------------------------------網站
設置num.partitions,分區數量與broker數量一致ui
------------------------------------------------- Zookeeper -------------------------------------------------
設置zookeeper集羣地址,zookeeper.connect = xxx.xxx.xxx.xxx:2181,xxx.xxx.xxx.xxx2181 (最重要的)
2)修改zookeeper.properties:
設置鏈接參數,在最後添加配置
tickTime=2000
initLimit=8
syncLimit=3
設置broker.id的服務器地址,server.X和IP要與broker.id所在的服務器地址一致
server.0=xxx.xxx.xxx.xxx:2888:3888
server.1=xxx.xxx.xxx.xxx:2889:3889
3)添加zookeeper數據目錄的ID文件,在zookeeper數據目錄(默認dataDir=/tmp/zookeeper)添加myid文件,寫入broker.id的值。到/tmp/zookeeper目錄下執行:
第一臺機器:echo 0 > myid
第二臺機器:echo 1 > myid
3. 啓動kafka
啓動時,先啓動zookeeper,再啓動kafka;關閉反之,先關閉kafka,再關閉zookeeper
啓動zookeeper: bin/zookeeper-server-start.sh config/zookeeper.properties &
啓動kafka: bin/kafka-server-start.sh config/server.properties &
4. 測試kafka集羣是否部署成功
1)第一臺機器上建立一個TOPIC
bin/kafka-topics.sh --create --zookeeper xxx.xxx.xxx.xxx:2181 --replication-factor 1 --partitions 1 --topic test
2)查看TOPIC列表,確認是否建立成功
bin/kafka-topics.sh --list --zookeeper xxx.xxx.xxx.xxx:2181
3)建立生成者
bin/kafka-console-producer.sh --broker-list xxx.xxx.xxx.xxx:9092 --topic test
4)在全部服務器上建立消費者
bin/kafka-console-consumer.sh --bootstrap-server xxx.xxx.xxx.xxx:9092 --from-beginning --topic test
5)在第一臺機器上輸入消息,回車發送,CTRL+C終止,查看其餘機器的消費者是否能接受到消息
###那些年踩過的坑.....
1. WARN: Connection to node 1 could not be established. Broker may not be available.
建立消費者時出的錯,重啓zookeeper和kafka
2. ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: replication factor: 1 larger than available brokers: 0
kafka未啓動,先中止kafka和zookeeper,確保進程關閉,而後再從新啓動。
bin/kafka-server-stop.sh
bin/zookeeper-server-stop.sh
bin/zookeeper-server-start.sh config/zookeeper.properties &
bin/kafka-server-start.sh config/server.properties &
3. WARN Error while fetching metadata with correlation id 0
啓動生產者進程報錯,沒有綁定Kafka啓動監聽的host信息
vim config/server.properties
listeners=PLAINTEXT://localhost:9092 ,若此處配置的IP,則在執行命令時使用IP:bin/kafka-console-consumer.sh --bootstrap-server xxx.xxx.xxx.xxx:9092 --from-beginning --topic test
4. UnknowHostException:主機名:主機名
linux沒法解析域名致使,能夠將主機名對應的ip寫入到hosts文件中保存,或者直接刪除 /etc/Hostname 文件
vim /tec/hosts
IP 主機名 (如:172.10.1.1 name)
