bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic kk_log
报错如下：
WARN [Consumer clientId=consumer-1, groupId=console-consumer-507] Connection to node -1 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)
配置server.confg时候设置的
advertised.listeners=PLAINTEXT://10.171.222.26:9092
此时需要用配置的IP而非localhost地址：
nohup bin/zookeeper-server-start.sh config/zookeeper.properties > /dev/null 2>&1 &
nohup bin/kafka-server-start.sh config/server.properties > /dev/null 2>&1 &
netstat -ntpl|egrep "(2181|9092)"
运行起来再试试
bin/kafka-console-consumer.sh --bootstrap-server 10.171.222.26:9092 --topic kk_log
应该就可以了。
做个小笔记。
PS zookeeper 报错，宕掉；

解决方法
报错原因：服务器上还有应用在不停的向zookeeper发送请求
解决方法：
用top -u [username]查看该用户下的所有进程，发现多了一个java进程在运行着；
1、kill掉与java相关的进程；
2、关闭zookeeper，删除zoo.cfg中的dataDir配置的文件夹；
3、重启zookeeper。
