无法启动kafka

[myDemoMike]

./bin/connect-distributed.sh ./config/connect-distributed-Oracle.properties ./config/OracleSourceConnector.properties 启动kafka服务会出现这种错误 Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient:725)。貌似只有指定config/server.properties才能正常启动。这个端口都起不来。请问是什么问题哈
