从apache官网下载相应的版本信息地址https://kafka.apache.org/downloads找到1.1.1版本下载即可这里下载kafka_2.12-1.1.1.tgz下载地址https://archive.apache.org/dist/kafka/1.1.1/kafka_2.12-1.1.1.tgz 这里的版本号有两段前一段为Scala的版本号后一段为Kafka的版本现在最新版本已经到3.X这里用1.1.1主要是项目特殊需要建议还是用高版本的。
Scala 2.11 和 Scala 2.12 是 Scala 编程语言的两个主要版本它们之间存在一些关键的区别
1. 性能优化Scala 2.12 在性能方面做了很多优化特别是在 JVM 上。它引入了值类Value Classes的改进减少了运行时的开销。Scala 2.11 的性能相对较低但它的优化主要集中在稳定性和兼容性上。
2. 字符串插值Scala 2.12 引入了新的字符串插值语法使用 s 前缀例如 sHello, $name。Scala 2.11 使用的是旧的字符串插值语法使用 #{}例如 Hello, #{name}。
3. 隐式转换Scala 2.12 对隐式转换进行了一些改进使其更加安全和易于理解。Scala 2.11 的隐式转换机制相对较为复杂容易引起混淆。
4. 模块化Scala 2.12 引入了模块化系统允许开发者将代码分割成多个模块便于管理和维护。Scala 2.11 没有模块化系统所有代码都放在一个项目中。
5. 兼容性Scala 2.12 相对于 Scala 2.11 有一些不兼容的更改特别是在 API 和库的使用上。因此从 Scala 2.11 迁移到 Scala 2.12 可能需要一些工作。Scala 2.11 是一个长期支持LTS版本这意味着它将获得更长时间的支持和维护。
6. 社区支持Scala 2.12 是目前的主流版本得到了广泛的社区支持和库的更新。Scala 2.11 虽然仍然在使用但社区支持逐渐减少。
总结如果你正在开发一个新的项目建议使用 Scala 2.12 或更高版本以获得更好的性能和更多的功能。如果你正在维护一个现有的 Scala 2.11 项目可以考虑在适当的时候迁移到 Scala 2.12但需要注意兼容性问题。部署
1、解压文件执行 tar -zxvf kafka_2.12-1.1.1.tgz 2、解压后路径为 [roottest kafka_2.12-1.1.1]# pwd /data/public/kafka/kafka_2.12-1.1.1 3、修改config/server.properties注意修改listeners和advertised.listeners即可

broker.id0############################# Socket Server Settings ############################## The address the socket server listens on. It will get the value returned from
# java.net.InetAddress.getCanonicalHostName() if not configured.
# FORMAT:
# listeners listener_name://host_name:port
# EXAMPLE:
# listeners PLAINTEXT://your.host.name:9092
listenersPLAINTEXT://192.138.31.100:9092# Hostname and port the broker will advertise to producers and consumers. If not set,
# it uses the value for listeners if configured. Otherwise, it will use the value
# returned from java.net.InetAddress.getCanonicalHostName().
advertised.listenersPLAINTEXT://192.138.31.100:9092# Maps listener names to security protocols, the default is for them to be the same. See the config documentation for more details
#listener.security.protocol.mapPLAINTEXT:PLAINTEXT,SSL:SSL,SASL_PLAINTEXT:SASL_PLAINTEXT,SASL_SSL:SASL_SSL# The number of threads that the server uses for receiving requests from the network and sending responses to the network
num.network.threads3# The number of threads that the server uses for processing requests, which may include disk I/O
num.io.threads8# The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer.bytes102400# The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer.bytes102400# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes409600000############################# Log Basics ############################## A comma separated list of directories under which to store log files
log.dirs/tmp/kafka-logs# The default number of log partitions per topic. More partitions allow greater
# parallelism for consumption, but this will also result in more files across
# the brokers.
num.partitions1# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
# This value is recommended to be increased for installations with data dirs located in RAID array.
num.recovery.threads.per.data.dir1############################# Internal Topic Settings #############################
# The replication factor for the group metadata internal topics __consumer_offsets and __transaction_state
# For anything other than development testing, a value greater than 1 is recommended for to ensure availability such as 3.
offsets.topic.replication.factor1
transaction.state.log.replication.factor1
transaction.state.log.min.isr1############################# Log Flush Policy ############################## Messages are immediately written to the filesystem but by default we only fsync() to sync
# the OS cache lazily. The following configurations control the flush of data to disk.
# There are a few important trade-offs here:
# 1. Durability: Unflushed data may be lost if you are not using replication.
# 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
# 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to excessive seeks.
# The settings below allow one to configure the flush policy to flush data after a period of time or
# every N messages (or both). This can be done globally and overridden on a per-topic basis.# The number of messages to accept before forcing a flush of data to disk
#log.flush.interval.messages10000# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms1000############################# Log Retention Policy ############################## The following configurations control the disposal of log segments. The policy can
# be set to delete segments after a period of time, or after a given size has accumulated.
# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
# from the end of the log.# The minimum age of a log file to be eligible for deletion due to age
log.retention.hours168# A size-based retention policy for logs. Segments are pruned from the log unless the remaining
# segments drop below log.retention.bytes. Functions independently of log.retention.hours.
#log.retention.bytes1073741824# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes1073741824# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms300000############################# Zookeeper ############################## Zookeeper connection string (see zookeeper docs for details).
# This is a comma separated host:port pairs, each corresponding to a zk
# server. e.g. 127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002.
# You can also append an optional chroot string to the urls to specify the
# root directory for all kafka znodes.
zookeeper.connectlocalhost:2181# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms6000############################# Group Coordinator Settings ############################## The following configuration specifies the time, in milliseconds, that the GroupCoordinator will delay the initial consumer rebalance.
# The rebalance will be further delayed by the value of group.initial.rebalance.delay.ms as new members join the group, up to a maximum of max.poll.interval.ms.
# The default value for this is 3 seconds.
# We override this to 0 here as it makes for a better out-of-the-box experience for development and testing.
# However, in production environments the default value of 3 seconds is more suitable as this will help to avoid unnecessary, and potentially expensive, rebalances during application startup.
group.initial.rebalance.delay.ms0启动
1、先启动Zookeeper执行 nohup /data/public/kafka/kafka_2.12-1.1.1/bin/zookeeper-server-start.sh /data/public/kafka/kafka_2.12-1.1.1/config/zookeeper.properties /dev/null 21
2、然后启动Kafka执行 nohup /data/public/kafka/kafka_2.12-1.1.1/bin/kafka-server-start.sh /data/public/kafka/kafka_2.12-1.1.1/config/server.properties /dev/null 21
3、检查是否启动
[roottest kafka_2.12-1.1.1]# netstat -nltp | grep -E (2181|9092)
tcp6 0 0 192.168.31.100:9092 :::* LISTEN 970022/java
tcp6 0 0 :::2181 :::* LISTEN 966577/java表明Kafka已经启动起来其中2181为Zookeeper的端口9092为Kafka的端口
开启客户端访问
firewall-cmd --zonepublic --add-port2181/tcp --permanent firewall-cmd --zonepublic --add-port9092/tcp --permanent firewall-cmd --reload
使用Offset Explorer 2.0访问 配置完成后连接服务器这时就可以使用Kafka进行生产和消费消息了。
