SSHキーの生成

ssh-keygen の -C オプションはコメント。指定しないと ユーザー名@コンピュータ名 のようになる。

-f オプションで保存するファイル名を指定する。

% cd ~/.ssh
% mkdir github
% ssh-keygen -t rsa -C "foomin10@gmail.com" -f "github/id_rsa"
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

% chmod 600 github/id_rsa

% cd ~/.ssh
% mkdir bitbucket
% ssh-keygen -t rsa -C "foomin10@gmail.com" -f "bitbucket/id_rsa"
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:

% chmod 600 bitbucket/id_rsa

config の編集

~/.ssh/config を作成する

Host github.com
  IdentityFile ~/.ssh/github/id_rsa
  User git
  HostName github.com
  Port 22
  TCPKeepAlive yes
  IdentitiesOnly yes
Host bitbucket.org
  IdentityFile ~/.ssh/bitbucket/id_rsa
  User git
  HostName bitbucket.org
  Port 22
  TCPKeepAlive yes
  IdentitiesOnly yes

chmod 600 ~/.ssh/config でパーミッションを設定
