1、自动化安装脚本

#!/bin/bash

#zhouyihua

#v0.1

#2021-07-20

rpm -qa | grep wget

if [ $? != 0 ] ; then

                yum install wget

        else

                        echo "wget already exist"

                fi

                #config DNS

                echo nameserver 8.8.8.8 > /etc/resolv.conf

                #download jdk

                wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u141-b15/336fa29ff2bb4ef291e347e091f7f4a7/jdk-8u141-linux-x64.tar.gz"

                tar -zxvf jdk-8u141-linux-x64.tar.gz

                #config java env

                echo "export JAVA_HOME=$PWD/jdk1.8.0_141" >> /etc/profile

                echo 'export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH' >> /etc/profile

                echo 'export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib' >>  /etc/profile

                source /etc/profile

              #download kafka

              cd /opt

                #wget  https://mirrors.tuna.tsinghua.edu.cn/apache/kafka/2.8.0/kafka_2.13-2.8.0.tgz --no-check-certificate  -O kafka_2.13-2.8.0.tgz

                wget  https://mirrors.bfsu.edu.cn/apache/kafka/2.8.0/kafka_2.13-2.8.0.tgz  --no-check-certificate

                tar -zxvf kafka_2.13-2.8.0.tgz

                cd kafka_2.13-2.8.0

                #background start zookeeper

                ./bin/zookeeper-server-start.sh ./config/zookeeper.properties 1>/dev/null 2>&1 &

                #config kafka

                cp -rf config/server.properties config/server.properties.bak

                hostip=$(ifconfig | grep inet | head -n 1 | awk '{print $2}')

                sed -i "s/#listeners=PLAINTEXT:\/\/:9092/listeners=PLAINTEXT:\/\/${hostip}:9092/"  config/server.properties

                sed -i "s/dataDir=\/tmp\/zookeeper/dataDir=\/opt\/zookeeper/" /opt/kafka_2.13-2.8.0/config/zookeeper.properties

                sed -i "s/log.dirs=\/tmp\/kafka-logs/log.dirs=\/opt\/kafka-logs/"  /opt/kafka_2.13-2.8.0/config/server.properties

                #background start kafka

                ./bin/kafka-server-start.sh ./config/server.properties 1>/dev/null 2>&1 &

                rm -rf  kafka_2.13-2.8.0.tgz

                exit

2、测试

创建一个topic

#cd /root/kafka_2.13-2.8.0/bin

./kafka-topics.sh --create --zookeeper localhost:2181 --config max.message.bytes=12800000 --config flush.messages=1 --replication-factor 1 --partitions 1 --topic test

在topic中添加消息

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

添加后使用ctrl+c中断

查看topic

./kafka-topics.sh  --describe --zookeeper localhost:2181 --topic test

消费topic中的消息

./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning

添加后使用ctrl+c中断

查看broker的数量：

./zookeeper-shell.sh  127.0.0.1:2181

ls /brokers/ids
