如何在ubuntu16.04版本下安装kafka

1. 在安装kafka之前，需要在ubuntu中安装和配置java的jdk。

2. 下载官方网站中的kafka的tgz文件包

wget http://www-us.apache.org/dist/kafka/2.7.0/kafka_2.13-2.7.0.tgz

3. 解压tgz文件包

tar xzf kafka_2.13-2.7.0.tgz

4. 新建zookeeper.service文件

vim /etc/systemd/system/zookeeper.service

5. 配置zookeeper.service文件

[Unit]

8. 更新系统设置

systemctl daemon-reload
