服务器 git clone 提示 Permission denied，用同样的 key 却在 MacBook 可以克隆下来，请大家提供下思路

用 Bitbucket 托管代码，服务器 git clone git@bitbucket.org:xxx/xxx.git 提示

Permission denied (publickey).
fatal: Could not read from remote repository.

ssh -v git@bitbucket.org

结果如下

You can use git or hg to connect to Bitbucket. Shell access is disabled.

This deploy key has read access to the following repositories:

okchum/enbo: root@west -- root@west
debug1: client_input_channel_req: channel 0 rtype exit-status reply 0
debug1: channel 0: free: client-session, nchannels 1
Connection to bitbucket.org closed.

但是奇怪的是 MacBook 上用同样的 private key 克隆，没问题。看起来是服务器问题。已经多次生成 key pairs ，将 public key 放到 bitbucket 了，没解决问题。也试过 chmod 600 ~/.ssh/id_rsa

ssh-add -l 也有这个 private key

大家帮忙看下还有什么思路解决？

谢谢大伙
