启动失败日志

缺少启动参数

在这里插入图片描述

输入行太长

组合起来的执行命令太长，Windows系统不支持。将项目放到盘符目录下。
在这里插入图片描述

找不到类

为了解决路径太长，去掉了一级目录。因为启动命令中有通过当前命令的位置去加载jar包。

绝对路径配置文件加载报错

# 文件地址错误
/kafka_2.13-3.6.1/bin/windows/zookeeper-server-start.bat /kafka_2.13-3.6.1/config/zookeeper.properties

在这里插入图片描述

先对路径无法启动

./bin/windows/zookeeper-server-start.bat ./bin/windows/zookeeper.properties

/bin/windows/zookeeper-server-start.bat /bin/windows/zookeeper.properties

bin/windows/zookeeper-server-start.bat bin/windows/zookeeper.properties

启动成功

1. 启动zookeeper

# 当前路径下启动
zookeeper-server-start.bat ../../config/zookeeper.properties

# 将文件复制一份到启动命令处
zookeeper-server-start.bat zookeeper.properties

# 绝对路径启动
/kafka_2.13-3.6.1/bin/windows/zookeeper-server-start.bat /kafka_2.13-3.6.1/bin/windows/zookeeper.properties

/kafka_2.13-3.6.1/bin/windows/zookeeper-server-start.bat /kafka_2.13-3.6.1/config/zookeeper.properties

# Window使用相对路径 系统找不到指定的路径
/bin/windows/zookeeper-server-start.bat /bin/config/zookeeper.properties

/kafka_2.13-3.6.1/bin/windows/zookeeper-server-start.bat /kafka_2.13-3.6.1/bin/config/zookeeper.properties

# 相对路径启动
call ./bin/windows/zookeeper-server-start.bat ./config/zookeeper.properties

call ./bin/windows/zookeeper-server-start.bat ./bin/windows/zookeeper.properties

在这里插入图片描述
ctrl + C停止，或者关闭窗口

3.启动kafka-server

# 当前路径下启动 将文件复制一份到启动命令处
kafka-server-start.sh config/server.properties

# 其他方式启动同上
