############################# Server Basics #############################
# The role of this server. Setting this puts us in KRaft mode
process.roles=broker,controller
# The node id associated with this instance's roles
node.id=1
# The connect string for the controller quorum
controller.quorum.voters=1@localhost:9093
############################# Socket Server Settings #############################
# The address the socket server listens on.
# Combined nodes (i.e. those with `process.roles=broker,controller`) must list the controller listener here at a minimum.
# If the broker listener is not defined, the default listener will use a host name that is equal to the value of java.net.InetAddress.getCanonicalHostName(),
# with PLAINTEXT listener name, and port 9092.
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://:9092,CONTROLLER://:9093
# Name of listener used for communication between brokers.
inter.broker.listener.name=PLAINTEXT
# Listener name, hostname and port the broker will advertise to clients.
# If not set, it uses the value for "listeners".
advertised.listeners=PLAINTEXT://localhost:9092
# A comma-separated list of the names of the listeners used by the controller.
# If no explicit mapping set in `listener.security.protocol.map`, default will be using PLAINTEXT protocol
# This is required if running in KRaft mode.
controller.listener.names=CONTROLLER
############################# Log Basics #############################
# A comma separated list of directories under which to store log files

kraft到底支不支持Windows啊？？？还是kafka版本的问题？？？
放弃！！！
2.2Kafka with ZooKeeper
需要1个zk节点，3个kafka节点。
2.2.1 同样需要3份kafka应用
2.2.2 分别修改配置文件
kafka_cluster_node1\config\server.properties
XML
broker.id=1
zookeeper.connect=localhost:2181

可以启动独立部署的zk，也可以用kafka自带的zk
bash
%kafka_home%\bin\windows\zookeeper-server-start.bat ../../config/zookeeper.properties2.2.4 Start the Kafka broker service
分别启动kafka节点
bash
kafka_cluster_node1\bin\windows\kafka-server-start.bat ../../config/server.properties
kafka_cluster_node2\bin\windows\kafka-server-start.bat ../../config/server.properties
kafka_cluster_node3\bin\windows\kafka-server-start.bat ../../config/server.properties
集群部署成功！！！
但是应用发送消息尚有问题，留个hook在此。
3 Linux单机
3.1 Kafka with KRaft
操作与windows一致，一把就成功，没有任何问题。（果然！！！）
3.2Kafka with ZooKeeper
还没有验证。
4 Windows集群（3台虚拟机）
4.1 Kafka with KRaft
常见异常
异常1：
这是因为单节点启动时产生的 tmp\kafka-logs\meta.properties文件中broker.id与现在集群的各节点不一致的原因（如果前面各节点输出的日志目录不同也不会产生这个问题）
XML
#Thu Sep 21 16:56:50 CST 2023
cluster.id=bkuCLgUiRYe5CSnptF6ZVQ
version=0
broker.id=0可以修改为一致或者直接删除。
异常2：
由于是在同一个机器上做集群，advertised.listeners配置需要区分，可以通过修改etc/hosts实现
XML
localhost kafkaNode1
localhost kafkaNode2
localhost kafkaNode3异常3：
还是因为在同一个主机上做集群的原因，listeners端口要区分开，可以分别设置为9092、9093、9094解决。
异常4：
hosts文件中配置域名映射时要使用127.0.0.1，不能使用localhost。
异常5：
应用端异常，说明spring.kafka.bootstrap-servers配置错误，应该配置advertised.listeners的地址。
异常6：
应用端发送消息时出现异常Error: NOT_LEADER_OR_FOLLOWER，
悬而未决
异常7：
linux集群环境
就是防火墙原因，三个节点9093端口不通，添加iptables规则，问题解决。
Error Codes
官方文档：Apache Kafka
We use numeric codes to indicate what problem occurred on the server. These can be translated by the client into exceptions or whatever the appropriate error handling mechanism in the client language. Here is a table of the error codes currently in use:
| ERROR | CODE | RETRIABLE | DESCRIPTION |
|---|---|---|---|
| UNKNOWN_SERVER_ERROR | -1 | False | The server experienced an unexpected error when processing the request. |
| NONE | 0 | False | |
| OFFSET_OUT_OF_RANGE | 1 | False | The requested offset is not within the range of offsets maintained by the server. |
| CORRUPT_MESSAGE | 2 | True | This message has failed its CRC checksum, exceeds the valid size, has a null key for a compacted topic, or is otherwise corrupt. |
| UNKNOWN_TOPIC_OR_PARTITION | 3 | True | This server does not host this topic-partition. |
| INVALID_FETCH_SIZE | 4 | False | The requested fetch size is invalid. |
| LEADER_NOT_AVAILABLE | 5 | True | There is no leader for this topic-partition as we are in the middle of a leadership election. |
| NOT_LEADER_OR_FOLLOWER | 6 | True | For requests intended only for the leader, this error indicates that the broker is not the current leader. For requests intended for any replica, this error indicates that the broker is not a replica of the topic partition. |
| REQUEST_TIMED_OUT | 7 | True | The request timed out. |
| BROKER_NOT_AVAILABLE | 8 | False | The broker is not available. |
| REPLICA_NOT_AVAILABLE | 9 | True | The replica is not available for the requested topic-partition. Produce/Fetch requests and other requests intended only for the leader or follower return NOT_LEADER_OR_FOLLOWER if the broker is not a replica of the topic-partition. |
| MESSAGE_TOO_LARGE | 10 | False | The request included a message larger than the max message size the server will accept. |
| STALE_CONTROLLER_EPOCH | 11 | False | The controller moved to another broker. |
| OFFSET_METADATA_TOO_LARGE | 12 | False | The metadata field of the offset request was too large. |
| NETWORK_EXCEPTION | 13 | True | The server disconnected before a response was received. |
| COORDINATOR_LOAD_IN_PROGRESS | 14 | True | The coordinator is loading and hence can't process requests. |
| COORDINATOR_NOT_AVAILABLE | 15 | True | The coordinator is not available. |
| NOT_COORDINATOR | 16 | True | This is not the correct coordinator. |
| INVALID_TOPIC_EXCEPTION | 17 | False | The request attempted to perform an operation on an invalid topic. |
| RECORD_LIST_TOO_LARGE | 18 | False | The request included message batch larger than the configured segment size on the server. |
| NOT_ENOUGH_REPLICAS | 19 | True | Messages are rejected since there are fewer in-sync replicas than required. |
| NOT_ENOUGH_REPLICAS_AFTER_APPEND | 20 | True | Messages are written to the log, but to fewer in-sync replicas than required. |
| INVALID_REQUIRED_ACKS | 21 | False | Produce request specified an invalid value for required acks. |
| ILLEGAL_GENERATION | 22 | False | Specified group generation id is not valid. |
| INCONSISTENT_GROUP_PROTOCOL | 23 | False | The group member's supported protocols are incompatible with those of existing members or first group member tried to join with empty protocol type or empty protocol list. |
| INVALID_GROUP_ID | 24 | False | The configured groupId is invalid. |
| UNKNOWN_MEMBER_ID | 25 | False | The coordinator is not aware of this member. |
| INVALID_SESSION_TIMEOUT | 26 | False | The session timeout is not within the range allowed by the broker (as configured by group.min.session.timeout.ms and group.max.session.timeout.ms). |
| REBALANCE_IN_PROGRESS | 27 | False | The group is rebalancing, so a rejoin is needed. |
| INVALID_COMMIT_OFFSET_SIZE | 28 | False | The committing offset data size is not valid. |
| TOPIC_AUTHORIZATION_FAILED | 29 | False | Topic authorization failed. |
| GROUP_AUTHORIZATION_FAILED | 30 | False | Group authorization failed. |
| CLUSTER_AUTHORIZATION_FAILED | 31 | False | Cluster authorization failed. |

| UNSUPPORTED_SASL_MECHANISM | 33 | False | The broker does not support the requested SASL mechanism. |
| ILLEGAL_SASL_STATE | 34 | False | Request is not valid given the current SASL state. |
| UNSUPPORTED_VERSION | 35 | False | The version of API is not supported. |
| TOPIC_ALREADY_EXISTS | 36 | False | Topic with this name already exists. |
| INVALID_PARTITIONS | 37 | False | Number of partitions is below 1. |
| INVALID_REPLICATION_FACTOR | 38 | False | Replication factor is below 1 or larger than the number of available brokers. |
| INVALID_REPLICA_ASSIGNMENT | 39 | False | Replica assignment is invalid. |
| INVALID_CONFIG | 40 | False | Configuration is invalid. |
| NOT_CONTROLLER | 41 | True | This is not the correct controller for this cluster. |
| INVALID_REQUEST | 42 | False | This most likely occurs because of a request being malformed by the client library or the message was sent to an incompatible broker. See the broker logs for more details. |
| UNSUPPORTED_FOR_MESSAGE_FORMAT | 43 | False | The message format version on the broker does not support the request. |
| POLICY_VIOLATION | 44 | False | Request parameters do not satisfy the configured policy. |
| OUT_OF_ORDER_SEQUENCE_NUMBER | 45 | False | The broker received an out of order sequence number. |
| DUPLICATE_SEQUENCE_NUMBER | 46 | False | The broker received a duplicate sequence number. |

| TRANSACTIONAL_ID_AUTHORIZATION_FAILED | 53 | False | Transactional Id authorization failed. |
| SECURITY_DISABLED | 54 | False | Security features are disabled. |
| OPERATION_NOT_ATTEMPTED | 55 | False | The broker did not attempt to execute this operation. This may happen for batched RPCs where some operations in the batch failed, causing the broker to respond without trying the rest. |
| KAFKA_STORAGE_ERROR | 56 | True | Disk error when trying to access log file on the disk. |
| LOG_DIR_NOT_FOUND | 57 | False | The user-specified log directory is not found in the broker config. |
| SASL_AUTHENTICATION_FAILED | 58 | False | SASL Authentication failed. |
| UNKNOWN_PRODUCER_ID | 59 | False | This exception is raised by the broker if it could not locate the producer metadata associated with the producerId in question. This could happen if, for instance, the producer's records were deleted because their retention time had elapsed. Once the last records of the producerId are removed, the producer's metadata is removed from the broker, and future appends by the producer will return this exception. |
| REASSIGNMENT_IN_PROGRESS | 60 | False | A partition reassignment is in progress. |
| DELEGATION_TOKEN_AUTH_DISABLED | 61 | False | Delegation Token feature is not enabled. |
| DELEGATION_TOKEN_NOT_FOUND | 62 | False | Delegation Token is not found on server. |

| GROUP_MAX_SIZE_REACHED | 81 | False | The consumer group has reached its max size. |
| FENCED_INSTANCE_ID | 82 | False | The broker rejected this static consumer since another consumer with the same group.instance.id has registered with a different member.id. |
| ELIGIBLE_LEADERS_NOT_AVAILABLE | 83 | True | Eligible topic partition leaders are not available. |
