黑猴子的家：Kafka集群部署

1、 集群规划

2、 jar包下载

http://kafka.apache.org/downloads.html

3、虚拟机准备

1）准备3台虚拟机
2）配置ip地址
3）配置主机名称
4）配置主机名映射hosts
5）禁用selinux
6）关闭防火墙
7）安装jdk

8）安装 zookeeper

4、Kafka集群部署

1）解压安装包

[[email protected] software]$ tar -xzvf kafka_2.11-0.11.0.0.tgz -C /opt/module/

2）添加软连接

[[email protected] software]$ cd /opt/module
[[email protected] module]$ ln -s kafka_2.11-0.11.0.0 kafka

3）在/opt/module/kafka目录下创建logs文件夹

[[email protected] module]$ cd kafka/
[[email protected] kafka]$ mkdir logs

4）修改配置文件

[[email protected] kafka]$ cd config/
[[email protected] config]$ vim server.properties

#输入以下内容
#broker的全局唯一编号，不能重复
broker.id=0

#删除topic功能 **
delete.topic.enable=true

#处理网络请求的线程数量
num.network.threads=3

#用来处理磁盘IO的现成数量
num.io.threads=8

#发送套接字的缓冲区大小
socket.send.buffer.bytes=102400

#接收套接字的缓冲区大小
socket.receive.buffer.bytes=102400

#请求套接字的缓冲区大小
socket.request.max.bytes=104857600

#kafka运行日志存放的路径
log.dirs=/opt/module/kafka/logs

#topic在当前broker上的分区个数
num.partitions=1

#用来恢复和清理data下数据的线程数量
num.recovery.threads.per.data.dir=1

#segment文件保留的最长时间，超时将被删除
log.retention.hours=168

#配置连接Zookeeper集群地址
zookeeper.connect=node1:2181,node2:2181,node3:2181

5）配置环境变量

[[email protected] module]# vim /etc/profile

#KAFKA_HOME
export KAFKA_HOME=/opt/module/kafka
export PATH=$PATH:$KAFKA_HOME/bin
:wq

[[email protected] module]# source /etc/profile

6）分发安装包

[[email protected] ~]# cd /etc
[[email protected] etc]# rsync -rvl profile [email protected]:/etc/profile
[[email protected] etc]# rsync -rvl profile [email protected]:/etc/profile
[[email protected] etc]# su - victor
[[email protected] ~]$ cd /opt/module/
[[email protected] module]$ rsync -rvl kafka_2.11-0.11.0.0 [email protected]: /opt/module/
[[email protected] module]$ rsync -rvl kafka_2.11-0.11.0.0 [email protected]:/opt/module/
[[email protected] module]$ rsync -rvl kafka [email protected]: /opt/module/kafka
[[email protected] module]$ rsync -rvl kafka [email protected]:/opt/module/kafka

7）修改server.properties

分别在node2和node3上修改配置文件/opt/module/kafka/config/server.properties中的broker.id=1、broker.id=2

node2

[[email protected] ~]$ cd /opt/module/kafka/config/
[[email protected] config]$ vim server.properties
broker.id=1

node3

[[email protected] ~]$ cd /opt/module/kafka/config/
[[email protected] config]$ vim server.properties
broker.id=2
尖叫提示：broker.id不得重复

8）启动集群
首先启动zookeeper,然后依次在node1、node2、node3节点上启动kafka
启动zookeeper

[[email protected] zookeeper-3.4.10]# bin/zkServer.sh start
[[email protected] zookeeper-3.4.10]# bin/zkServer.sh start
[[email protected] zookeeper-3.4.10]# bin/zkServer.sh start

启动kafka

[[email protected] kafka]$ bin/kafka-server-start.sh config/server.properties &
[[email protected] kafka]$ bin/kafka-server-start.sh config/server.properties &
[[email protected] kafka]$ bin/kafka-server-start.sh -daemon config/server.properties
尖叫提示：“-daemon”和“&”都表示后台运行， 如果忘记切到后台运行 →  Ctrl + z →  bg

9）关闭集群

[[email protected] kafka]$ bin/kafka-server-stop.sh config/server.properties
[[email protected] kafka]$ bin/kafka-server-stop.sh config/server.properties
[[email protected] kafka]$ bin/kafka-server-stop.sh config/server.properties
[[email protected] kafka]$ kill -9 8953
