我正在为 OpenShift 项目使用 rhc cli 工具。我遇到了默认 rhc ssh key 的问题。
在任何与 ssh 相关的操作(设置、应用程序创建等)上，rhc 创建 ~/.ssh/id_rsa键，如果它不存在。我不喜欢这种行为，我希望它使用像 ~/.ssh/OpenShift-SSH-Keys/my_id_rsa 这样的东西.
因为在 rhc 设置期间，它没有询问我要从哪个位置加载 key 。因此我也查看了~/.openshift/express.conf我只看到了 ssl 的配置；不是ssh。
所以我在互联网上找到了以下配置行添加到 ~/.openshift/express.conf :ssh_key_file='~/.ssh/OpenShift-SSH-Keys/my_id_rsa'
我添加了它并修改了我的~/.ssh/config文件:
# Openshift *.rhcloud.com ssh-key config
Host *.rhcloud.com
IdentityFile ~/.ssh/OpenShift-SSH-Keys/my_id_rsa
IdentitiesOnly yes
VerifyHostKeyDNS yes
StrictHostKeyChecking no
PasswordAuthentication no
UserKnownHostsFile ~/.ssh/known_hosts
最后，我像这样设置我的帐户:
rhc setup --config ~/.openshift/express.conf -l myusername@gmail.com此命令行的输出:

正如您在命令行的输出中看到的那样:
No SSH keys were found. We will generate a pair of keys for you. ，虽然我在 ~/.openshift/express.conf 中指定了我已经生成了 ssh key ，rhc setup没有考虑他们或没有找到他们。所以根据你们的说法，是否可以在 rhc 设置期间以某种方式为 ssh key 加载指定不同的位置？
注意:我知道如何添加额外的 ssh key ，但我想停止 rhc 创建/使用
~/.ssh/id_rsa
最佳答案
据我所知，你只想要 rhc不使用您的默认 ssh key 。因此，这里是您如何创建一个单独的 key 并配置 rhc 以使用它而不是默认 key 。
关键点是:
no在 rhc
setup 期间生成和上传 ssh key rhc sshkey add 单独添加您的 key 在您的原始示例中列出
这是否涵盖了您的担忧？

Enter file in which to save the key (/home/crackit/.ssh/id_rsa): /home/crackit/my_key_location/key.rsa

更新 :我没有注意到生成了 key 。但我确信
rhc setup 期间生成的 key 没有实际使用。首先是因为默认位置的 key 永远不会添加到 openshift。您可以在下面看到一个快速证明。另一种查看方式是rhc sshkeys list .另一件事是，如果您在默认位置已经有 key ，则不会生成 key (在这种情况下，您仍然选择
no 不上传它们)。但它实际上是 IMO 中的一个小错误 rhc无需询问用户即可生成 ssh key 。这可能是一个非常罕见的用例 - 您没有默认 key 并且您想使用来自非标准位置的 key (这不是您在标准位置有 key 的用例，只是不想使用它)但仍然 IMO 不应该生成用户没有请求的东西。因此，我将向您展示仅使用我想要的自定义 key 的方式:[crackit@koTapaH ~]$ rm -rf .ssh/id_rsa*
[crackit@koTapaH ~]$ rhc ssh tmp

config known_hosts

更新 2 当然 token 不能帮助你使用 ssh:
[crackit@koTapaH ~]$ rm -rf my_key_location
[crackit@koTapaH ~]$ rhc ssh tmp
Connecting to 550000a0e0b8cdca4c000040@tmp-foobar.rhcloud.com ...
no such identity: /home/crackit/my_key_location/key.rsa: No such file or directory
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
SSH key 用于 ssh。 token 用于 API 请求。这些是不同的用例。 rhc 使用
ssh在下面可执行，因此使用自定义键意味着编辑 ~/.ssh/config将默认 key 设置为另一个位置或为不同的主机设置不同的 key 。 rhc setup 处理得不好.但是一旦你有了你的 key 集，你就不必运行 rhc setup了。
关于ssh - 如何在 rhc 设置期间为 ssh key 加载指定不同的位置？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34550515/
