SSH接続しようとしたら秘密鍵のパーミッションエラーがでた

Last updated at Posted at 2018-04-29

概要

新しくvagrant環境を作り、git push しようとしたら、なぜか秘密鍵がないといわれまして。。。
そこで、もともと使っていた環境のSSH鍵をコピーし、再実行しようとしたら、怒られた。

vagrant@vagrant:/vagrant/trunk-web$ git push origin now_branch
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0664 for '/home/vagrant/.ssh/id_rsa' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "/home/vagrant/.ssh/id_rsa": bad permissions
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

どうやら鍵がオープンすぎたらしい。
まぁコピー&ペーストしただけだからね。

解決方法

鍵のパーミッションを0600にしてあげるといいらしい。

$ chmod 0600 ~/.ssh/id_rsa

これでもう1回git push したところ、きちんとできました\(^○^)/
