02_001 Kafka 开机自启动 Ubuntu

由于使用的wsl，有些命令是使用不到了 如：systemctl 等但不妨碍使用，非wsl环境可以顺畅使用
1、cd /etc/init.d/

2、sudo touch kafka（举例）

3、给服务赋权限：sudo chmod +x kafka

4、vim kafka
`#!/bin/bash

chkconfig: 2345 10 90

description: kafkaService ....

export JAVA_HOME=/opt/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.😒{JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

echo $"Usage: $0 {start|stop|restart}"
exit 1
esac
