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

1. 在官网下载tar包 https://zookeeper.apache.org/releases.html#download

2. 模拟集群
   建立三个文件夹，将tar包解压到文件夹内
   

3. 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

4. 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
   

5. 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

1. 从kafka官网下载tar包，http://kafka.apache.org/downloads
   下载后解压。
2. 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

3. 通过以下命令启动：

sh bin/kafka-server-start.sh config/server.properties

4. 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

在config文件下建立kafka_server_jaas.conf文件

KafkaServer {
	org.apache.kafka.common.security.plain.PlainLoginModule required
	username="kafka"
	password="kafka#secret"
	user_kafka="kafka#secret"
	user_alice="alice#secret"
        user_rd.kafka="ddpay123";
};

5. 本地配置host
   
   kafka服务器配置host
   

6. 官网下载可视化工具 https://www.kafkatool.com/download.html 连接kafka
   
   

org.apache.kafka.common.security.plain.PlainLoginModule required username="kafka" password="kafka#secret";
