Docker安装kafka

安装

# 拉取镜像
docker pull wurstmeister/zookeeper
docker pull wurstmeister/kafka

# 启动zookeeper容器（Zookeeper用于崩溃检测，实现Topic发现，和维护Topic的生产和消费状态）
docker run -t -d -p 2181:2181 --name zookeeper wurstmeister/zookeeper

# 启动kafka容器
docker run  -d --name kafka -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.0.253:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.0.253:9092 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 -t wurstmeister/kafka

这里面主要设置了4个参数，根据自己的机子Ip进行修改即可

KAFKA_BROKER_ID=0               
KAFKA_ZOOKEEPER_CONNECT={主机IP}:2181
KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://{主机IP}:9092
KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092

中间两个参数的 {主机IP} 改为宿主机器的IP地址（服务器改为服务器外网ip），如果不这么设置，可能会导致在别的机器上访问不到kafka。最后的0.0.0.0:9092 无需修改。
