集群搭建

鏡像選擇

Zookeeper和Kafka集群分別運(yùn)行在不同的容器中
zookeeper官方鏡像，版本3.4
kafka采用wurstmeister/kafka鏡像

專注于為中小企業(yè)提供成都做網(wǎng)站、成都網(wǎng)站設(shè)計(jì)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)睢陽免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了成百上千家企業(yè)的穩(wěn)健成長，幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

集群規(guī)劃

hostname	Ip addr	port	listener
zoo1	172.19.0.11	2184:2181
zoo2	172.19.0.12	2185:2181
zoo3	172.19.0.13	2186:2181
kafka1	172.19.0.14	9092:9092	kafka1
kafka2	172.19.0.15	9093:9093	kafka2
Kafka3	172.19.0.16	9094:9094	Kafka3
宿主機(jī)root OSX	192.168.21.139【DHCP獲取，會(huì)變動(dòng)】

實(shí)現(xiàn)目標(biāo)

kafka集群在docker網(wǎng)絡(luò)中可用，和zookeeper處于同一網(wǎng)絡(luò)
宿主機(jī)可以訪問zookeeper集群和kafka的broker list
docker重啟時(shí)集群自動(dòng)重啟
集群的數(shù)據(jù)文件映射到宿主機(jī)器目錄中
使用yml文件和$ docker-compose up -d命令創(chuàng)建或重建集群

$ docker-compose up -d

結(jié)果查看和測試

宿主機(jī)命令行創(chuàng)建topic

$ pwd
/Users/shaozhipeng/Development/kafka_2.11-2.0.0/bin
$ ./kafka-topics.sh --create --zookeeper localhost:2184,localhost:2185,localhost:2186 --replication-factor 1 --partitions 1 --topic test1

Kafka Tool查看

docker ps查看正在運(yùn)行的容器

查看宿主機(jī)IP地址，并設(shè)置Host

這樣宿主機(jī)就可以訪問kafka集群了
