我是meshbie，用於ssh和mysql命令。 我有一個使用無密碼驗證從一臺linux服務器備份到另一臺linux服務器的問題。我已經生成了無密碼身份驗證的密鑰並將其上傳到另一臺服務器。使用ssh從linux服務器備份命令問題
我已經使用這個命令
[[email protected] ~]$ mysqldump -u dbuser -p"dbpwd" --opt dbname | gzip -c | ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/...../known_hosts -l deploy -i /...../id_rsa -v [email protected] "/bin/cat > [email protected]:/......./test.sql.gz" 2>&1
現在，當我在SSH運行的命令，我得到了下面的錯誤
debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
debug1: Next authentication method: gssapi-keyex
debug1: No valid Key exchange context

debug1: Offering public key: /home/indus33/.ssh/id_rsa
我用Google搜索了很多，但沒有辦法幫我。
如果有人對此有疑問，請問我。
請幫我解決這個問題。

我運行命令
[用戶@ server1的〜] $ SSH -o StrictHostKeyChecking =沒有-o UserKnownHostsFile =/..../known_hosts中-l部署-i /。 .../id_rsa -v user2的@服務器2

希望這個問題將清除所有.....
究竟發生了什麼（hangup/exit/signalX）？你能檢查服務器端GS？ –
我沒有檢查任何服務器端日誌。 –
也許你可以粘貼確切的命令行和腳本的內容？ （例如，您可以用ls替換真正的備份命令，例如更容易調試。） –
