一）安裝JDK

步驟1：新建路徑/usr/Java, 并在其下解壓 jdk-7u71-linux-x64.tar.gz

# mkdir -p /usr/java

# tar -zxvf jdk-7u71-linux-x64.tar.gz

步驟2：添加JDK到系統(tǒng)環(huán)境變量

# vi /etc/profile

新增以下內(nèi)容：

export JAVA_HOME=/usr/java/jdk1.7.0_71

export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

步驟3：使配置生效

source /etc/profile #使配置文件立即生效

# java -version //JDK版本java version "1.7.0_79" 也可以，目前JDK1.8版本不支持；

Java version "1.7.0_71"

Java(TM) SE Runtime Environment (build 1.7.0_71-b14)

Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)

二）安裝zookeeper

步驟1：解壓zookeeper安裝包(路徑無關(guān)，安裝路徑可以自定義)

# tar -zxvf zookeeper-3.3.6.tar.gz

步驟2：配置環(huán)境變量

# vim /etc/profile

export zookeeper_home=/home/laoyang/zookeeper

#source /etc/profile

# sh $zookeeper_home/bin/zkServer.sh start

JMX enabled by default

Using config: /home/laoyang/zookeeper/bin/../conf/zoo.cfg

grep: /home/laoyang/zookeeper/bin/../conf/zoo.cfg: No such file or directory

Starting zookeeper ... STARTED

三）安裝kafka

步驟1：解壓&移動到/usr/local

# tar -xzvf kafka_2.11-0.9.0.1.tgz

# mv kafka_2.11-0.9.0.1 /usr/local/kafka

步驟2：配置kafka，修改server.properties

# mkdir /usr/local/kafka/log/kafka #創(chuàng)建kafka日志目錄

# cd /usr/local/kafka/config #進入配置目錄

# vim server.properties #編輯修改相應(yīng)的參數(shù)

broker.id=0
port=9092 #端口號
host.name=10.8.5.101 #服務(wù)器IP地址，修改為自己的服務(wù)器IP
log.dirs=/usr/local/kafka/log/kafka #日志存放路徑，上面創(chuàng)建的目錄
zookeeper.connect=localhost:2181 #zookeeper地址和端口，單機配置部署，localhost:2181

步驟3、配置kafka下的zookeeper

# mkdir /usr/local/kafka/zookeeper #創(chuàng)建zookeeper目錄

# mkdir /usr/local/kafka/log/zookeeper #創(chuàng)建zookeeper日志目錄

# cd /usr/local/kafka/config #進入配置目錄

# vim zookeeper.properties #編輯修改相應(yīng)的參數(shù)

dataDir=/usr/local/kafka/zookeeper #zookeeper數(shù)據(jù)目錄
dataLogDir=/usr/local/kafka/log/zookeeper #zookeeper日志目錄
clientPort=2181
maxClientCnxns=100
tickTime=2000
initLimit=10
syncLimit=5

步驟4：創(chuàng)建啟動、關(guān)閉kafka腳本

1）創(chuàng)建啟動kafka腳本

#cd /usr/local/kafka/bin/

# vim kafkastart.sh

#!/bin/bash
#啟動zookeeper
/usr/local/kafka/bin/zookeeper-server-start.sh /usr/local/kafka/config/zookeeper.properties &
sleep 3
#Start kafka
/usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties &

2）創(chuàng)建關(guān)閉kafka腳本

# vim kafkastop.sh

#!/bin/bash
#stop zookeeper
/usr/local/kafka/bin/zookeeper-server-stop.sh /usr/local/kafka/config/zookeeper.properties &
sleep 3
#Stop kafka
/usr/local/kafka/bin/kafka-server-stop.sh /usr/local/kafka/config/server.properties &

3）#添加腳本執(zhí)行權(quán)限

chmod +x kafkastart.sh

chmod +x kafkastop.sh

4）設(shè)置腳本開機自動執(zhí)行

# vim /etc/rc.d/rc.local #編輯，在最后添加一行

sh /usr/local/kafka/kafkastart.sh & ＃設(shè)置開機自動在后臺運行腳本
sh /usr/local/kafka/kafkastart.sh #啟動kafka
sh /usr/local/kafka/kafkastop.sh #關(guān)閉kafka

到此為止CentOs6.5下Kafka安裝配置完成。

成功標志：

四）測試kafka

步驟1：啟動zookeeper

# sh $zookeeper_home/bin/zkServer.sh start

JMX enabled by default

Using config: /home/laoyang/zookeeper/bin/../conf/zoo.cfg

grep: /home/laoyang/zookeeper/bin/../conf/zoo.cfg: No such file or directory

Starting zookeeper ... STARTED

步驟2：啟動kafka

# ./kafkastart.sh

步驟3：測試創(chuàng)建topic

# cd /usr/local/kafka/bin

# ./kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

步驟4：通過list命令查看創(chuàng)建的topic

# cd /usr/local/kafka/bin

# ./kafka-topics.sh –list –zookeeper localhost:2181

步驟5：生產(chǎn)消息測試

# ./kafka-console-producer.sh --broker-list localhost:9092 --topic test

Kafka test! //這里的“Kafka test!”為手動輸入的，輸入后“ctrl +c”退出；

步驟6：消費消息測試

# ./kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

I'm laoyang #之前測試輸入的內(nèi)容

kafka test!

經(jīng)過上面幾步，代表kafka安裝成功。

五）停止kafka

步驟1：停止Kafka

cd /usr/local/kafka

# ./kafkastop.sh //這里的kafka進程并沒有關(guān)掉，需要手動kill

步驟2：停止Zookeeper server

# sh $zookeeper_home/bin/zkServer.sh stop

至此，啟動，測試，停止全過程ok。

kafka啟動過程中的報錯：

WARN caught end of stream exception (org.apache.zookeeper.server.NIOServerCnxn)

EndOfStreamException: Unable to read additional data from client sessionid 0x157ac94cd940002, likely client has closed socket

at org.apache.zookeeper.server.NIOServerCnxn.doIO(NIOServerCnxn.java:228)

at org.apache.zookeeper.server.NIOServerCnxnFactory.run(NIOServerCnxnFactory.java:208)

at java.lang.Thread.run(Thread.java:745)

報錯原因：

zookeeper服務(wù)端和客戶端的jar版本不一致導致的；

解決辦法：

從zookeeper服務(wù)端安裝目錄的根目錄復(fù)制zookeeper-xxx.jar到kafka安裝目錄下的libs目錄下即可，將kafka下libs目錄下的jar包刪除；

報錯：

java.lang.RuntimeException: A broker is already registered on the path /brokers/ids/1. This probably indicates that you either have configured a brokerid that is already in use, or else you have shutdown this broker and restarted it faster than the zookeeper timeout so it appears to be re-registering.
at kafka.utils.ZkUtils$.registerBrokerInZk(ZkUtils.scala:205)
at kafka.server.KafkaHealthcheck.register(KafkaHealthcheck.scala:57)
at kafka.server.KafkaHealthcheck.startup(KafkaHealthcheck.scala:44)
at kafka.server.KafkaServer.startup(KafkaServer.scala:103)
at kafka.server.KafkaServerStartable.startup(KafkaServerStartable.scala:34)
at kafka.Kafka$.main(Kafka.scala:46)
at kafka.Kafka.main(Kafka.scala)

報錯原因：

該錯誤是由于server.properties中的broker.id重復(fù)

解決辦法：

# vim server.properties

# The id of the broker. This must be set to a unique integer for each broker.

broker.id=0
