kafka安装&ip访问&权限认证
安装kafka前需要先安装zookeep
zookeeper环境搭建
-
在官网下载tar包 https://zookeeper.apache.org/releases.html#download
-
模拟集群
建立三个文件夹，将tar包解压到文件夹内 -
在每个conf目录下创建zoo.cfg文件，
在zookeeper-1的配置文件添加
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/root/lpl/data/zk1/data
dataLogDir=/root/lpl/log/zk1/log
clientPort=2181
server.1=localhost:2287:3387
server.2=localhost:2288:3388
server.3=localhost:2289:3389
在zookeeper-2的配置文件添加
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/root/lpl/data/zk2/data
dataLogDir=/root/lpl/log/zk2/log
clientPort=2182
server.1=localhost:2287:3387
server.2=localhost:2288:3388
server.3=localhost:2289:3389
在zookeeper-3的配置文件添加
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/root/lpl/data/zk3/data
dataLogDir=/root/lpl/log/zk3/log
clientPort=2183
server.1=localhost:2287:3387
server.2=localhost:2288:3388
server.3=localhost:2289:3389
-
之后再配置的每个data目录下添加myid文件，内容对应server.x中的x
-
分别运行bin下面的zkServer.sh脚本
sh bin/zkServer.sh start
三个全部启动后，使用
sh bin/zkCli.sh -server localhost:2181
连接，成功的话如图所示。
kafka环境搭建
- 从kafka官网下载tar包，http://kafka.apache.org/downloads
下载后解压。 - 修改config目录下的server.properties配置文件
listeners=PLAINTEXT://localhost:9092
zookeeper.connect=localhost:2181
修改config目录下的zookeeper.properties配置文件
dataDir=/tmp/zookeeper
clientPort=2181
admin.enableServer=false
- 通过以下命令启动：
sh bin/kafka-server-start.sh config/server.properties
- 网络访问&权限认证
查看本机host
在server.properties 配置host及权限认证

############################# Server Basics #############################
# The id of the broker. This must be set to a unique integer for each broker.
broker.id=0
############################# 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 = SASL_PLAINTEXT://17b3c6855069:9092
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
listeners=SASL_PLAINTEXT://: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.listeners=SASL_PLAINTEXT://17b3c6855069:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN
# 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.map=PLAINTEXT: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.threads=3
# The number of threads that the server uses for processing requests, which may include disk I/O
num.io.threads=8
# The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer.bytes=102400
# The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer.bytes=102400
# The maximum size of a request that the socket server will accept (protection against OOM)
socket.request.max.bytes=104857600
############################# 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.partitions=1
# 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.dir=1
############################# 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 to ensure availability such as 3.
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
############################# 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.messages=10000
# The maximum amount of time a message can sit in a log before we force a flush
#log.flush.interval.ms=1000
############################# 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.hours=168
# 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.bytes=1073741824
# The maximum size of a log segment file. When this size is reached a new log segment will be created.
log.segment.bytes=1073741824
# The interval at which log segments are checked to see if they can be deleted according
# to the retention policies
log.retention.check.interval.ms=300000
############################# 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.connect=17b3c6855069:2181
# Timeout in ms for connecting to zookeeper
zookeeper.connection.timeout.ms=18000
############################# 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.ms=0
主要参数如下：
listeners=SASL_PLAINTEXT://:9092
advertised.listeners=SASL_PLAINTEXT://17b3c6855069:9092
security.inter.broker.protocol=SASL_PLAINTEXT
sasl.enabled.mechanisms=PLAIN
sasl.mechanism.inter.broker.protocol=PLAIN
