当我尝试carbon-cache.py start通过设置运行时

ENABLE_MANHOLE = True
MANHOLE_INTERFACE = 127.0.0.1
MANHOLE_PORT = 7222
MANHOLE_USER = admin
MANHOLE_PUBLIC_KEY = ssh-rsa AAAAB3NzaC1yc2EAAAABiwAaAIEAoxN0sv/e4eZCPpi3N3KYvyzRaBaMeS2RsOQ/cDuKv11dlNzVeiyc3RFmCv5Rjwn/lQ79y0zyHxw67qLyhQ/kDzINc4cY41ivuQXm2tPmgvexdrBv5nsfEpjs3gLZfJnyvlcVyWK/lId8WUvEWSWHTzsbtmXAF2raJMdgLTbQ8wE=

我收到以下错误

Starting carbon-cache (instance a)
An error has occurred: b"ConchError: ('no host keys, failing', None)"
Please look at log file for more information.

作为新手，我无法理解如何解决它。

Twisted 16.1 对 Twisted Conch（实现检修孔功能）进行了更改，使其不再使用硬编码的 SSH 主机密钥对。有关详细信息，请参阅https://twistedmatrix.com/trac/ticket/8229。

为了解决这个问题，carbon-cache 应该获取配置变量来指定公共和私有主机密钥，并使用其和属性在ConchFactory实例上设置它们。我查看了当前的实现 carbon's ，它有：publicKeysprivateKeysmanhole.py

def createManholeListener(): # ... sessionFactory = ConchFactory(sshPortal) return sessionFactory

这应该修改如下：

def createManholeListener(): # ... sessionFactory = ConchFactory(sshPortal) sessionFactory.publicKeys[b'ssh-rsa'] = keys.Key.fromString(settings.MANHOLE_HOST_RSA_PUBLIC_KEY) sessionFactory.privateKeys[b'ssh-rsa'] = keys.Key.fromString(settings.MANHOLE_HOST_RSA_PRIVATE_KEY) return sessionFactory

这假设密钥是用 生成的ssh-keygen -t rsa。如果您想支持其他键类型，则两个 dicts 都由指定键类型的字节字符串索引。
