KAFKA_ADVERTISED_HOST_NAME: kafka1
KAFKA_ZOOKEEPER_CONNECT: zookeeper:
kafkamanager
docker run -it -d --net zookeeper_default --link kafka-zookeeper-1:zookeeper --link kafka-kafka1-1:kafka --link kafka-kafka2-1:kafka --link kafka-kafka3-1:kafka -p 9000:9000 -e ZK_HOSTS=192.168.1.6:2181 sheepkiller/kafka-manager
注意这里我遇到了三个坑：
1：网段不同 导致容器启动失败
/usr/bin/docker-current: Error response from daemon: Cannot link to /kafka-kafka1-1, as it does not belong to the default network.
这是因为之前部署的zookeeper和kafka在同一个网络中，而kafkmanager是另外部署的，重新启了一个容器，他们就不在一个网络中了，所以需要加一个 --net zookeepe_default
这是查询容器网络的命令，然后使用--link连接相应的网段
docker network ls
2：容器启动成功但是kafkamanager连不上zookeeper
没有指定IP，导致连接zookeeper失败
docker run -it -d --net zookeeper_default --link kafka-zookeeper-1:zookeeper --link kafka-kafka1-1:kafka --link kafka-kafka2-1:kafka --link kafka-kafka3-1:kafka -p 9000:9000 -e ZK_HOSTS=zookeeper:2181 sheepkiller/kafka-manager
o.a.z.ClientCnxn - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1081) ~[org.apache.zookeeper.zookeeper-3.4.6.jar:3.4.6-1569965]
然后我就指定了具体的IP问题得到解决
docker run -it -d --net zookeeper_default --link kafka-zookeeper-1:zookeeper --link kafka-kafka1-1:kafka --link kafka-kafka2-1:kafka --link kafka-kafka3-1:kafka -p 9000:9000 -e ZK_HOSTS=192.168.1.6:2181 sheepkiller/kafka-manager
3：没有关闭防火墙，在访问http://192.168.1.6:9000/ 页面时报错
关闭防火墙后解决
//查看防火墙状态
systemctl status firewalld
//关闭防火墙
systemctl stop firewalld
//永久关闭防火墙
systemctl disable firewalld
//启用防火墙
systemctl enable firewalld
//开启防火墙
systemctl start firewalld
