docker搭建kafka集群(高级版)

1. 环境docker, docker-compose

2.zookeeper集群

/data/zookeeper/zoo1/config/zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
# dataDir=/opt/zookeeper-3.4.13/data
dataDir=/data
dataLogDir=/datalog
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1

server.1=zoo1:2888:3888
server.2=zoo2:2888:3888
server.3=zoo3:2888:3888

 

 

docker-compose-zookeeper.yml

version: '3.7'

      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 # zookeeper节点列表

启动

docker-compose -f docker-compose-zookeeper.yml up -d

3.kafka集群

需要先创建虚拟机网络

docker network create -d bridge --subnet 172.19.0.0/24 kafka_net

docker-compose-kafka.yml

version: '3.2'
services:
  broker1:
    container_name: broker1
    hostname: broker1
    image: wurstmeister/kafka
    privileged: true
    restart: unless-stopped

启动

docker-compose -f docker-compose-kafka.yml up -d

4. 遇到的问题:

在同一台集群上部署zookeeper集群和kafka集群，会报错：

/usr/bin/start-kafka.sh: line 149: /opt/kafka/bin/kafka-server-start.sh: No such file or direc

原因：可能是因为端口冲突导致docker容器没启动，然后报错。认真检查端口吧!
