报错信息：
Error contacting service. It is probably not running.
一次启动三个节点：
# zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
报错信息查案zookeeper.out
# zkServer.sh status

--zookeeper关闭：
# zkServer.sh start
--查看zookeeper的信息：

--设置环境变量：
--启动kafka：
# /usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties &
-- 启动：
# /usr/local/kafka/bin/kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties &
注意：kafka的broker_id的值要和zookeeper的ID值一样。
--启动之后可以查看jps进程：
# jps
22851 Kafka
22884 Jps
22151 QuorumPeerMain
QuorumPeerMain为zookeeper的进程，kafka为kafka的进程。
--kafka常用的操作命令：
注释以下命令需要设置环境变量：
# cat /etc/profile.d/kafka.sh
export PATH=$PATH:/usr/local/kafka/bin
--关闭kafka：
kafka-server-stop.sh
--启动kafka：
kafka-server-start.sh -daemon /usr/local/kafka/config/server.properties
--创建topic：
说明：创建一个主题名为topic_tidb的主题，有2个复制3个分区
kafka-topics.sh --create --zookeeper 10.19.85.149,10.19.15.103,10.19.189.221 --replication-factor 2 --partitions 3 --topic topic_tidb
WARNING: Due to limitations in metric names, topics with a period ('.') or underscore ('_') could collide. To avoid issues it is best to use either, but not both.
Created topic "topic_tidb".
--查看topic是否创建成功：
kafka-topics.sh --list --zookeeper 10.19.85.149,10.19.15.103,10.19.189.221
topic_tidb
--查看topic_tidb的详细信息：
# kafka-topics.sh --describe --zookeeper 10.19.85.149,10.19.15.103,10.19.189.221 --topic topic_tidb
Topic:topic_tidbPartitionCount:3ReplicationFactor:2Configs:
Topic: topic_tidbPartition: 0Leader: 2Replicas: 2,3Isr: 2,3
Topic: topic_tidbPartition: 1Leader: 3Replicas: 3,1Isr: 3,1
Topic: topic_tidbPartition: 2Leader: 1Replicas: 1,2Isr: 1,2
--删除Topic:
#kafka-topics.sh --delete --zookeeper 10.19.85.149,10.19.15.103,10.19.189.221 --topic topic_tidb
--创建消息生产者发送消息：
kafka-console-producer.sh --broker-list 10.19.85.149:9092,10.19.15.103:9092,10.19.189.221:9092 --topic topic_tidb
kafka-console-producer.sh --broker-list 10.19.85.149:9092,10.19.15.103:9092,10.19.189.221:9092 --topic topic_tidb

--创建消息消费者接收消息:
kafka-console-consumer.sh --zookeeper 10.19.85.149:2181,10.19.15.103:2181,10.19.189.221:2181 --from-beginning --topic topic_tidb
Using the ConsoleConsumer with old consumer is deprecated and will be removed in a future major release. Consider using the new consumer by passing [bootstrap-server] instead of [zookeeper].
