Centos6.5下kafka如何部署安裝

小編給大家分享一下Centos6.5下kafka如何部署安裝，希望大家閱讀完這篇文章之后都有所收獲，下面讓我們一起去探討吧！

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到系統環境變量

# vi /etc/profile

新增以下內容：

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，安裝路徑可以自定義)

# tar -zxvf zookeeper-3.3.6.tar.gz

步驟2：配置環境變量

# 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 #編輯修改相應的參數

1. broker.id=0

2. port=9092 #端口號

3. host.name=10.8.5.101  #服務器IP地址，修改為自己的服務器IP

4. log.dirs=/usr/local/kafka/log/kafka  #日志存放路徑，上面創建的目錄

5. 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 #創建zookeeper目錄

# mkdir /usr/local/kafka/log/zookeeper #創建zookeeper日志目錄

# cd /usr/local/kafka/config #進入配置目錄

# vim zookeeper.properties #編輯修改相應的參數

1. dataDir=/usr/local/kafka/zookeeper #zookeeper數據目錄

2. dataLogDir=/usr/local/kafka/log/zookeeper #zookeeper日志目錄

3. clientPort=2181

4. maxClientCnxns=100

5. tickTime=2000

6. initLimit=10

7. syncLimit=5
   

步驟4：創建啟動、關閉kafka腳本

1）創建啟動kafka腳本

#cd  /usr/local/kafka/bin/

# vim kafkastart.sh

1. #!/bin/bash

2. #啟動zookeeper

3. /usr/local/kafka/bin/zookeeper-server-start.sh /usr/local/kafka/config/zookeeper.properties &

4. sleep 3
   

5. #Start kafka

6. /usr/local/kafka/bin/kafka-server-start.sh /usr/local/kafka/config/server.properties &

2）創建關閉kafka腳本

# vim kafkastop.sh

1. #!/bin/bash

2. #stop zookeeper

3. /usr/local/kafka/bin/zookeeper-server-stop.sh /usr/local/kafka/config/zookeeper.properties &

4. sleep 3
   

5. #Stop kafka

6. /usr/local/kafka/bin/kafka-server-stop.sh /usr/local/kafka/config/server.properties &

3）#添加腳本執行權限

chmod +x kafkastart.sh

chmod +x kafkastop.sh

4）設置腳本開機自動執行

# vim /etc/rc.d/rc.local #編輯，在最后添加一行

1. sh /usr/local/kafka/kafkastart.sh & ＃設置開機自動在后臺運行腳本

2. sh /usr/local/kafka/kafkastart.sh #啟動kafka

3. sh /usr/local/kafka/kafkastop.sh #關閉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命令查看創建的topic

# cd /usr/local/kafka/bin

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

步驟5：生產消息測試

# ./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  #之前測試輸入的內容

kafka test!

經過上面幾步，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服務端和客戶端的jar版本不一致導致的 ；

解決辦法：

          從zookeeper服務端安裝目錄的根目錄復制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

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
