《Kafka系列》kafka创建topic失败， Replication factor: 1 larger than available brokers: 0

kafka创建topic失败， Replication factor: 1 larger than available brokers: 0

1.创建语句如下所示，按照习惯在添加zookeeper参数的时候，指定了zxy:2181/kafka，但是却创建失败，Error while executing topic command : Replication factor: 1 larger than available brokers: 0.

[root@zxy bin]# kafka-topics.sh --create --topic tp1 --zookeeper zxy:2181/kafka --partitions 3 --replication-factor 1
Error while executing topic command : Replication factor: 1 larger than available brokers: 0.
[2023-03-27 17:15:46,605] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 1 larger than available brokers: 0.
 (kafka.admin.TopicCommand$)

2.检查各个broker的server.properties文件

发现在配置参数的时候，zookeeper.connect指定的是zxy:2181,zxy:2182,zxy:2183

[root@zxy config]# cat server01.properties
broker.id=1
port=9091
listeners=PLAINTEXT://localhost:9091
log.dirs=/zxy/apps/kafkaCluster/kafkaLog01
zookeeper.connect=zxy:2181,zxy:2182,zxy:2183

3.指定zookeeper参数为zxy:2181，创建成功

[root@zxy bin]# kafka-topics.sh --create --topic tp1 --zookeeper zxy:2181 --partitions 3 --replication-factor 1
Created topic "tp1".
