ssh接続方法

Posted at

#SSH接続ができるようになるまで
パスワード認証を聞かれたくない人用です

まずは公開鍵と秘密鍵を作成

ssh-keygen

これで
id_rsa.pub 公開鍵
id_rsa 秘密鍵
ができます。

公開鍵をサーバーにアップロードしてそれをauthorized_keysとして登録

ssh-copy-id -i ~/.ssh/id_rsa.pub user@xxx.xxx.xx.xx

サーバー側の設定を書き換える

sudo vim /etc/sshsshd_congig

PublickeyAuthentication yesのところ#をとってコメントアウトを外し、sshdを再起動する

service ssh restart

最終的にこれで接続すればパスワード聞かれない

ssh -i ~/.ssh/id_rsa.pub user@xxx.xxx.xx.xx
