28、Kafka：Linux部署Kafka集群-程序员江小北

准备

准备三台虚拟机，IP地址分别为：

192.168.217.151

192.168.217.152

192.168.217.153

下载Jdk，Zookeeper和Kafka压缩包

下载地址：

https://download.csdn.net/download/weixin_41405524/87515680

上传压缩包到服务器

将压缩包分别上传到三台Kafka服务器的/usr/local/kafka目录下，备用

初始化环境

下载工具包

yum -y install vim lrzsz bash-completion

下载时钟同步

yum -y install chrony

systemctl start chronyd
systemctl enable chronyd
systemctl status chronyd

chronyc sources

关闭防火墙和安全认证

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

配置HOSTS文件

cat >> /etc/hosts << EOF
192.168.217.151 kafka1 # 工作节点1
192.168.217.152 kafka2 # 工作节点2
192.168.217.153 kafka3 # 工作节点3
EOF

创建/usr/local/kafka目录

mkdir /usr/local/kafka

cd /usr/local/kafka

安装JDK

解压

tar -xvf jdk-8u341-linux-x64.tar.gz && mv jdk1.8.0_341 jdk

编辑环境变量

cat >> /etc/profile  << EOF

export JAVA_HOME=/usr/local/kafka/jdk/

export JRE_HOME=$JAVA_HOME/jre

export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

export CLASSPATH=$JAVA_HOME/lib:$JRE_HOME/lib:./

EOF

source /etc/profile

查看版本

java -version

安装zookeeper

解压

tar -zxvf apache-zookeeper-3.6.4-bin.tar.gz 

mv apache-zookeeper-3.6.4-bin/ zookeeper

创建data和log目录

cd /usr/local/kafka/zookeeper

mkdir data && mkdir log

cd data

echo 1 > myid # 1,2,3

编辑配置文件

cd /usr/local/kafka/zookeeper/conf

mv zoo_sample.cfg zoo.cfg

vim zoo.cfg
dataDir=/usr/local/kafka/zookeeper/data

dataLogDir=/usr/local/kafka/zookeeper/log

server.1=192.168.217.151:2888:3888
 
server.2=192.168.217.152:2888:3888
 
server.3=192.168.217.153:2888:3888

配置环境变量

echo 'export ZOOKEEPER_HOME=/usr/local/kafka/zookeeper' >> /etc/profile
echo 'export PATH=$PATH:$ZOOKEEPER_HOME/bin' >> /etc/profile

source /etc/profile

启动Zookeeper

cd /usr/local/kafka/zookeeper

./bin/zkServer.sh start

查看状态

./bin/zkServer.sh status

./bin/zkServer.sh status ./conf/zoo.cfg

安装Kafka

解压文件，创建日志目录

cd /usr/local/kafka

tar -zxvf kafka_2.13-3.4.0.tgz 

mv kafka_2.13-3.4.0 kafka

cd kafka/

mkdir log

ll

编辑配置文件

cd /usr/local/kafka/kafka

vim config/server.properties

192、 168.217.151；

broker.id=1

listeners=PLAINTEXT://:9092
advertised.listeners=PLAINTEXT://192.168.217.151:9092

log.dirs=/usr/local/kafka/kafka/log

# topic 在当前broker上的分片个数，与broker保持一致
num.partitions=3

# 设置zookeeper集群地址与端口如下：
zookeeper.connect=192.168.217.151:2181,192.168.217.152:2181,192.168.217.153:2181

192、 1682.17.152；

启动Kafka集群

cd /usr/local/kafka/kafka

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

lsof -i:9092

创建主题，查看主题

进入kafka目录下

cd /usr/local/kafka/kafka

151节点下创建主题即可


./bin/kafka-topics.sh --create --replication-factor 3 --partitions 2 --topic kafkatopic --bootstrap-server 192.168.217.151:9092

查看主题

./bin/kafka-topics.sh --list --bootstrap-server 192.168.217.151:9092

创建生产者

进入kafka目录下

cd /usr/local/kafka/kafka

在151的broker上创建生产者

./bin/kafka-console-producer.sh --broker-list 192.168.217.151:9092 --topic kafkatopic

创建消费者

分别在152,153节点上创建消费者

./bin/kafka-console-consumer.sh --bootstrap-server 192.168.217.152:9092 --topic kafkatopic

./bin/kafka-console-consumer.sh --bootstrap-server 192.168.217.153:9092 --topic kafkatopic
