「git push ssh:〜」で「Permission denied (publickey).」とかなっちゃう件のメモ

失敗例

サーバ側（AWS Amazon Linux）

sudo mkdir /var/lib/git
sudo chown -R ec2-user /var/lib/git
cd /var/lib/git
mkdir demo.git
git init --bare demo.git

クライアント側

適当に何か作ってcommit

cd ~/projects/demo
echo 'hoge' > hoge.txt
git commit -m "first commit"
git init
git push ssh://ec2-xxx-xx-XX-xx.ap-northeast-1.compute.amazonaws.com/var/lib/git/demo.git master
    Permission denied (publickey).
    fatal: The remote end hung up unexpectedly

失敗となる

「Permission denied (publickey).」つうことなんで

クライアント側で

hogehost に秘密鍵を設定

秘密鍵が demo.pem の例

• ~/.ssh/config

Host hogehost
     HostName ec2-xxx-xx-xx-xx.ap-northeast-1.compute.amazonaws.com
     IdentityFile ~/.ssh/demo.pem
     User ec2-user

git push

git push ssh://hogehost/var/lib/git/demo.git master

    To ssh://aar14b/var/lib/git/demo.git
     * [new branch]      master -> master

エラーでなくなった

git remote add origin ssh://hogehost/var/lib/git/demo.git
git push origin
    Everything up-to-date

でけた(・∀・)
