我正在使用ansible进行配置管理。我将公钥和私钥对文件复制到远程服务器后克隆私有仓库。克隆工作正常，但当我运行bundle install时，收到public key permission denied的错误。

Gemfile通过gitub的ssh url使用私有gem。因此，在通过playbook运行bundle install时，会出现以下错误。
failed: [X.X.X.X] => {"changed": true, "cmd": ["bundle", "install"], "delta": "0:00:05.788387", "end": "2015-11-03 06:39:43.671879", "rc": 11, "start": "2015-11-03 06:39:37.883492", "warnings": []}
stderr: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights.
我添加到远程服务器的密钥也可以访问私有宝石，但不知何故它拒绝了许可。
我个人尝试通过ssh将repo克隆到远程服务器但无法访问任何repo（主repo和gem repo），尽管密钥被复制到远程服务器的~/.ssh/目标。

答案 0 :(得分：1)
你会注意到你在SSH输出中有
Trying private key: /home/ubuntu/.ssh/id_rsa debug1: could not open
key file '/home/ubuntu/.ssh/id_rsa': Permission denied debug1: Trying
private key: /home/ubuntu/.ssh/id_dsa debug3: no such identity:
/home/ubuntu/.ssh/id_dsa: No such file or directory debug1: Trying
private key: /home/ubuntu/.ssh/id_ecdsa debug3: no such identity:
/home/ubuntu/.ssh/id_ecdsa: No such file or directory debug1: Trying
private key: /home/ubuntu/.ssh/id_ed25519 debug3: no such identity:
/home/ubuntu/.ssh/id_ed25519: No such file or directory
第一行表示当前用户没有id_rsa的权限。
似乎你使用sudo来复制可能将文件所有权设置为root而不是ubuntu的密钥。
变化：
copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600
为：
copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600 owner=ubuntu
根据ansible docs，用户应该由
拥有该文件你也应该将两个文件（id_rsa和id_rsa.pub）放在同一个项目中，这样它就会在循环中运行它们
像：
- name: ensure public key and public one are present
sudo: yes
copy: src={{item}} dest=/home/ubuntu/.ssh/{{ item }} mode=0600
with_items:
- id_rsa.pub
- id_rsa
