kafka安装

1.安装下JDK环境

查看yum包含：yum search java 或者 yum list java*

安装JDK

yum install java-1.8.0-openjdk-devel.x86_64

配置环境变量

vi  /etc/profile

复制以下三行到文件中，按esc退出编辑模式，输入:wq保存退出

export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.el6_9.x86_64
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

注意路径要跟自己下载的JDK对应

全局变量立即生效

source  /etc/profile

查看 java -version

1.安装kafka

具体参考https://kafka.apache.org/quickstart

tar -xzf kafka_2.13-2.7.0.tgz
$ cd kafka_2.13-2.7.0

STEP 2: START THE KAFKA ENVIRONMENT

NOTE: Your local environment must have Java 8+ installed.

Run the following commands in order to start all services in the correct order:

# Start the ZooKeeper service
# Note: Soon, ZooKeeper will no longer be required by Apache Kafka.
$ bin/zookeeper-server-start.sh config/zookeeper.properties

Open another terminal session and run:

# Start the Kafka broker service
$ bin/kafka-server-start.sh config/server.properties

其他用户切换到如zw 要给文件赋值下权限 chmod -fR 777 mnt/application  tmp 等
