先说一下环境

• confluent7.0.0

• win10系统安装的wsl2的Ubuntu20.04子系统

• 在子系统中运行，jdk版本1.8

• 干净的confluent7.0.0按照https://blog.csdn.net/eyeofeagle/article/details/117999231的博客内容进行配置修改，他上面写的是192.168.56.7我全部写的loclhost

下面是我运行的情况

按照正常的情况执行confluent local services start应该会像下面这样

Starting Zookeeper
Zookeeper is [UP]
Starting Kafka
Kafka is [UP]
Starting Schema Registry
Schema Registry is [UP]
Starting Kafka REST
Kafka REST is [UP]
Starting Connect
Connect is [UP]
Starting KSQL Server
KSQL Server is [UP]
Starting Control Center
Control Center is [UP]

但是我的为什么会这样，显示失败但是是启动起来的，虽然这样最后也能启动成功进入http://localhost:9021/页面，但肯定是有问题的。

我查看了Linux系统里面的日志文件信息，和正常启动的没有区别，也没有看到相关的报错信息。
