尝试启动Kong时kong start
出现以下错误消息:
[INFO] Using configuration: /etc/kong/kong.yml
[INFO] Proxy port.........8000
Admin API port.....8001
Database...........cassandra keepalive=60000 port=9042 timeout=1000 hosts=127.0.0.1 keyspace=kong
[ERR] Cassandra error: Failed to read frame header from 127.0.0.1: closed
这是为什么?
