1.安装scala环境
第一种方法
1.访问scala的官网这里下载最新版的scala。
2.解压缩文件包，可将其移动至/usr/local/share下
mv /download/scalapath /usr/local/share
3.修改环境变量，在mac下使用sudo su进入管理员权限，修改配置文件profile，
vim /etc/profile
在文件的末尾加入
export PATH="$PATH:/usr/local/share/scala/bin"
:wq!保存退出，重启终端，完成scala的配置安装。
第二种方法
如果本机有安装Ruby的话则安装更加简单，可以借助Homebrew进行安装。 首先安装Homebrew
ruby -e “$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)”
再进行scala的安装brew install scala
2.安装ZooKeeper
安装三个ZooKeeper节点
下载ZooKeeper，地址
执行如下命令安装ZooKeeper：
tar -zxvf zookeeper-3.4.13.tar.gz
mv zookeeper-3.4.13.tar.gz zookeeper
mkdir /Users/XXX/kafka/data_logs
#依次创建三个zk节点的目录
#/Users/XXX/kafka/data_logs/zookeeper1目录下创建myid文件，文件中只含有此zk的id：1
mkdir /Users/XXX/kafka/data_logs/zookeeper1
#/Users/XXX/kafka/data_logs/zookeeper2目录下创建myid文件，文件中只含有此zk的id：2
mkdir /Users/XXX/kafka/data_logs/zookeeper2
#/Users/XXX/kafka/data_logs/zookeeper3目录下创建myid文件，文件中只含有此zk的id：3
mkdir /Users/XXX/kafka/data_logs/zookeeper3
zk配置文件创建：
#进入zookeeper-3.4.13.tar.gz解压之后的目录
cd /Users/XXX/kafka/zookeeper
#在conf目录下依次创建zoo1.cfg、zoo2.cfg、zoo3.cfg三个配置文件，内容如下：
zoo1.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=5
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=2
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/Users/fureitakara/kafka/data_logs/zookeeper1
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
zoo2.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=5
# The number of ticks that can pass between
# sending a request and getting an acknowledgement

# the directory where the snapshot is stored.

dataDir=/Users/fureitakara/kafka/data_logs/zookeeper2
# the port at which the clients will connect
clientPort=2182
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
zoo3.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=5
# The number of ticks that can pass between
# sending a request and getting an acknowledgement

# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/Users/fureitakara/kafka/data_logs/zookeeper3
# the port at which the clients will connect
clientPort=2183
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=127.0.0.1:2888:3888
server.2=127.0.0.1:2889:3889
server.3=127.0.0.1:2890:3890
注：上面三个配置文件的场景是在同一台机器配置多个zookeeper节点的情况下进行使用，如果是在多台机器上配置zookeeper节点的话，只需要一个zoo.cfg文件即可。
启动zookeeper：
如果是在一台机器上启动多个不同的zookeeper节点的话，使用如下命令：
java -cp zookeeper-3.4.13.jar:lib/slf4j-api-1.7.25.jar:lib/slf4j-log4j12-1.7.25.jar:lib/log4j-1.2.17.jar:conf org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo1.cfg
java -cp zookeeper-3.4.13.jar:lib/slf4j-api-1.7.25.jar:lib/slf4j-log4j12-1.7.25.jar:lib/log4j-1.2.17.jar:conf org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo2.cfg
java -cp zookeeper-3.4.13.jar:lib/slf4j-api-1.7.25.jar:lib/slf4j-log4j12-1.7.25.jar:lib/log4j-1.2.17.jar:conf org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo3.cfg
如果是在不同的机器上启动zookeeper节点的话，直接使用如下命令即可：
bin/zkServer.sh start conf/zoocfg
检查整个集群的状态：
bin/zkServer.sh status conf/zoo1.cfg
bin/zkServer.sh status conf/zoo2.cfg
bin/zkServer.sh status conf/zoo3.cfg
此时整个zookeeper集群搭建完毕
3.安装kafka集群
下载kafka地址
tar -zxvf kafka_2.12-2.0.0.tgz
mv kafka_2.12-2.0.0.tgz kafka_2.12
#zookeeper安装过程中已创建可以不用重复创建
mkdir /Users/XXX/kafka/data_logs
#创建kafka log目录
mkdir /Users/XXX/kafka/data_logs/kafka1
mkdir /Users/XXX/kafka/data_logs/kafka2
mkdir /Users/XXX/kafka/data_logs/kafka3
进入kafka解压目录
cd /Users/XXX/kafka/kafka
在config目录下构建三个kafka服务端配置文件：
server.properties:
#每个kafka服务id不同
broker.id=0
#每个kafka服务监听端口不一致
listeners=PLAINTEXT://127.0.0.1:9092
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
#每个kafka服务目录不一致
log.dirs=/Users/fureitakara/kafka/data_logs/kafka1
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.hours=168
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
#配置zk集群
zookeeper.connect=127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183
zookeeper.connection.timeout.ms=6000
group.initial.rebalance.delay.ms=0
delete.topic.enable=true
这个配置文件创建三份，上面有注释的地方进行每个服务的区分
启动kafka服务
bin/kafka-server-start.sh -daemon config/server1.properties
bin/kafka-server-start.sh -daemon config/server2.properties
bin/kafka-server-start.sh -daemon config/server3.properties
使用jps命令查看kafka服务状态：
jps |grep Kafka
kafka集群搭建完毕
4.验证
创建topic：
bin/kafka-topics.sh --zookeeper 127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183 --create --topic test-topic --partitions 3 --replication-factor 3
出现如输出即为成功：
fulibaodeMacBook-Pro:kafka fureitakara$ bin/kafka-topics.sh --zookeeper 127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183 --create --topic test-topic --partitions 3 --replication-factor 3
Created topic "test-topic".
进一步验证：
#列出所有topic
bin/kafka-topics.sh --zookeeper 127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183 -list
test-topic
#test-topic的详细描述
bin/kafka-topics.sh --zookeeper 127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183 --describe --topic test-topic
Topic:test-topic PartitionCount:3 ReplicationFactor:3 Configs:
Topic: test-topic Partition: 0 Leader: 1 Replicas: 1,2,0 Isr: 1,2,0
Topic: test-topic Partition: 1 Leader: 2 Replicas: 2,0,1 Isr: 2,0,1
Topic: test-topic Partition: 2 Leader: 0 Replicas: 0,1,2 Isr: 0,1,2
消息的发送与消费：
#生产者测试：
bin/kafka-console-producer.sh --broker-list 127.0.0.1:9092,127.0.0.1:9093,127.0.0.1:9094 --topic test-topic
>this is a test message
