我试图指定要使用的密钥，但由于某些原因，ssh仍使用不同的密钥，如下所示

将IdentitiesOnly yes添加到适当的.ssh / config部分以使ssh只提供指定的标识。 另外，正如上面提到的zhenech，你必须使用ssh BitBucket来使Host BitBucket部分的选项生效，或者添加bitbucket.org到Host 。 例如：
Host BitBucket bitbucket.org HostName bitbucket.org IdentityFile ~/.ssh/id_rsa IdentitiesOnly Yes
当你写Host BitBucket ，你也必须ssh BitBucket ，而不是真正的主机名（但你可以把它放到主线…）
我认为你得到的问题是因为你之前使用了其他的密钥。 请删除~/.ssh/known_hosts文件：
rm ~/.ssh/known_hosts
无论如何：
debug1: Authentication succeeded (publickey).
它工作正常，正在使用指定的相同密钥。 由于日志中指定的原因，连接被closures：不能直接使用密钥通过SSH连接，只能通过Git使用该密钥。
还有什么其他的你正在努力完成，因为它不是很清楚吗？
SSH不提供不同的密钥。
它正在尝试在您的configuration文件中指定的密钥，并且在validation失败之后，它会尝试在您的.ssh目录中find的任何其他密钥。
当它尝试wowza.key时，authenticationbuild立。
然而，由于某种原因，你正试图打开一个shell到bitbucket.org，这是不允许的，哪个bitbucket告诉你。
You can use git or hg to connect to Bitbucket. Shell access is disabled.
