私は ssh と mysql コマンドの mewbie です。パスワードレス認証を使用して、ある Linux サーバーから別の Linux サーバーにバックアップを取る際に問題があります。パスワードレス認証用のキーを既に生成しており、別のサーバーにアップロードしています。
このコマンドを使用しました
[user1@server1 ~]$ mysqldump -u dbuser -p"dbpwd" --opt dbname | gzip -c | ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/...../known_hosts -l deploy -i /...../id_rsa -v user2@server2 "/bin/cat > user2@server2:/......./test.sql.gz" 2>&1
SSHでコマンドを実行すると、以下のエラーが発生しました
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
debug1: Next authentication method: gssapi-keyex
debug1: No valid Key exchange context

私はたくさんグーグルで検索しましたが、解決策はありませんでした。
これについて質問がある場合は、私に頻繁に尋ねてください。
この問題を解決するのを手伝ってください。

コマンドを実行します
[user@server1 ~]$ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/..../known_hosts -l deploy -i /..../id_rsa -v user2@server2
