centos7.6如何安裝docker-zookeeper-kafka

這篇文章將為大家詳細講解有關centos7.6如何安裝docker-zookeeper-kafka，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。

單機方案：

# 安裝zookeeper
docker run -d \
    --name zk \
    -p 12181:2181 \
    -v /etc/localtime:/etc/localtime \
    --restart=always \
    zookeeper

# 安裝kafka
docker run -d \
    --name kafka \
    -p 9092:9092 \
    --link zk:zookeeper \
    -e KAFKA_BROKER_ID=0 \
    -e KAFKA_ZOOKEEPER_CONNECT=zk:2181 \
    -e KAFKA_LISTENERS=PLAINTEXT://:9092 \
    -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.1.100:9092 \
    --restart=always \
    wurstmeister/kafka

# 進入kafka
docker exec -it kafka /bin/bash

# 創建topic
/opt/kafka/bin/kafka-topics.sh --create --zookeeper zk:2181 --replication-factor 1 --partitions 1 --topic my_topic

# 查看topic列表
/opt/kafka/bin/kafka-topics.sh --list --zookeeper zk:2181

# 發送消息
/opt/kafka/bin/kafka-console-producer.sh --broker-list 122.228.113.229:9092 --topic my_topic

# 接受消息
/opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server 122.228.113.229:9092 --topic my_topic --from-beginning

集群方案： 

-- 安裝docker-compose
curl -L https://github.com/docker/compose/releases/download/1.24.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

-- 賦予執行權限
chmod +x /usr/local/bin/docker-compose

-- 拉取鏡像
docker pull zookeeper:3.4
docker pull wurstmeister/kafka

-- 編寫docker-compose.yaml

-- 啟動服務
docker run -d zookeeper

-- 測試zookeeper
telnet 127.0.0.1 12181
docker exec -it zoo1 bash ./bin/zkServer.sh status
docker exec -it zoo2 bash ./bin/zkServer.sh status
docker exec -it zoo3 bash ./bin/zkServer.sh status

-- 測試kafka
telnet 127.0.0.1 19092

-- 鏈接kafka1容器
docker exec -it kafka1 /bin/bash

-- 創建topic
$KAFKA_HOME/bin/kafka-topics.sh --create --topic test --zookeeper zoo1:2181 --replication-factor 1 --partitions 1

-- 查看topic
$KAFKA_HOME/bin/kafka-topics.sh --zookeeper zoo1:2181 --describe --topic test

-- 發布消息
$KAFKA_HOME/bin/kafka-console-producer.sh --topic=test --broker-list kafka1:9092

-- 接收消息
$KAFKA_HOME/bin/kafka-console-consumer.sh --bootstrap-server kafka1:9092 --from-beginning --topic test

mkdir -p /home/docker_zoo_kafka

cat > /home/docker_zoo_kafka/docker-compose.yml <<EOF
