docker 部署 zookeeper+kafka 集群

主机三台
172.16.100.61
172.16.100.62
172.16.100.63
Docker 版本 当前最新版

# 部署zk有2种方法

## 注意 \后不要跟空格

一 . 端口映射

172.16.100.61 执行

docker run -tid --name=zk- \
--restart=always \
--privileged=true \
-p : \
-p : \
-p : \
-e ZOO_MY_ID= \
-e ZOO_SERVERS=server.="0.0.0.0:2888:3888 server.2=172.16.100.62:2888:3888 server.3=172.16.100.63:2888:3888" \
-v /data/kafka_cluster/zookeeper/data:/data \
zookeeper:latest

172.16.100.62 执行

docker run -tid --name=zk- \
--restart=always \
--privileged=true \
-p : \
-p : \
-p : \
-e ZOO_MY_ID= \
-e ZOO_SERVERS=server.="172.16.100.61:2888:3888 server.2=0.0.0.0:2888:3888 server.3=172.16.100.63:2888:3888" \
-v /data/kafka_cluster/zookeeper/data:/data \
zookeeper:latest

172.16.100.63 执行

docker run -tid --name=zk- \
--restart=always \
--privileged=true \
-p : \
-p : \
-p : \
-e ZOO_MY_ID= \
-e ZOO_SERVERS=server.="172.16.100.61:2888:3888 server.2=172.16.100.62:2888:3888 server.3=0.0.0.0:2888:3888" \
-v /data/kafka_cluster/zookeeper/data:/data \
zookeeper:latest

#查看集群状态

docker exec -it zk- bash ./bin/zkServer.sh status

二.直接走宿主机IP

每台机器都执行一次,只需要修改 ZOO_MY_ID 即可 只要ZOO_SERVERS 和你的ID一致即可

docker run -tid --name=zk- \
--restart=always \
--privileged=true \
--net=host \
-e ZOO_MY_ID= \
-e ZOO_SERVERS=server.="172.16.100.61:2888:3888 server.2=172.16.100.62:2888:3888 server.3=172.16.100.63:2888:3888" \
-v /data/kafka_cluster/zookeeper/data:/data \
zookeeper:latest

### 上述zk检查过后没有问题就可以进行下一步了 ###

解析主机名

注意： kafka-logs-data-1 是主机的名字 如果你的主机是xxx 那这里应该改为kafka-logs-xxx

同时我映射了本地的hosts到容器里,所有容器获取到的主机名就是宿主机的名字

在61执行

docker run -itd --name=kafka \
--restart=always \
--net=host \
--privileged=true \
-v /etc/hosts:/etc/hosts \
-v /data/kafka_cluster/kafka/data:/kafka/kafka-logs-data- \
-v /data/kafka_cluster/kafka/logs:/opt/kafka/logs \
-e KAFKA_ADVERTISED_HOST_NAME=172.16.100.61 \
-e HOST_IP=172.16.100.61 \
-e KAFKA_ADVERTISED_PORT= \
-e KAFKA_ZOOKEEPER_CONNECT=172.16.100.61:,172.16.100.62:,172.16.100.63: \
-e KAFKA_BROKER_ID= \
-e KAFKA_HEAP_OPTS="-Xmx8196M -Xms8196M" \
wurstmeister/kafka:0.10.1.1 

在62执行

docker run -itd --name=kafka \
--restart=always \
--net=host \
--privileged=true \
-v /etc/hosts:/etc/hosts \
-v /data/kafka_cluster/kafka/data:/kafka/kafka-logs-data- \
-v /data/kafka_cluster/kafka/logs:/opt/kafka/logs \
-e KAFKA_ADVERTISED_HOST_NAME=172.16.100.62 \

-e KAFKA_ADVERTISED_PORT= \
-e KAFKA_ZOOKEEPER_CONNECT=172.16.100.61:,172.16.100.62:,172.16.100.63: \
-e KAFKA_BROKER_ID= \
-e KAFKA_HEAP_OPTS="-Xmx8196M -Xms8196M" \
wurstmeister/kafka:0.10.1.1

在63执行
