kafka的使用

//创建topics

kafka-topics.sh --create --zookeeper zookeeper-1.zookeeper:2181 --replication-factor 1 --partitions 1 --topic im-msg

//查看topics的信息

kafka-topics.sh --zookeeper zookeeper-1.zookeeper:2181 --describe --topic im_test

//查看日志

tail -f  $KAFKA_HOME/logs/server.log

    

kafka-topics.sh --list --zookeeper zookeeper-1.zookeeper:2181
kafka-consumer-groups.sh --zookeeper zookeeper-1.zookeeper:2181 --list

im_msg:1:2

kafka-topics.sh --zookeeper zookeeper-1.zookeeper:2181 --delete --topic "im-msg"

zkCli.sh -server zookeeper-1.zookeeper:2181

ls /brokers/topics

deleteall /brokers

kafka-topics.sh --zookeeper   zookeeper-1.zookeeper:2181 --describe  --topic im_test

kafka-topics.sh --create --zookeeper zookeeper-1.zookeeper:2181 --replication-factor 2 --partitions 1 --topic im-msg
kafka-topics.sh --zookeeper   zookeeper-1.zookeeper:2181 --describe  --topic im-msg

offsets.topic.replication.factor=1 
OFFSETS_TOPIC_REPLICATION_FACTOR
                                                                                                      
transaction.state.log.replication.factor=1   

kafka的集群部署：

1.清空zookeeper的breaks

2.通过yam文件修改zookeeper的地址

 

 3.修改后把pod 增加为3个
