rsync + rsync 失敗，因為主機密鑰驗證失敗

我使用rsync為了將文件從/etc/yum.repos.d/遠端伺服器傳輸到/etc/yum.repos.d/

sshpass -p $password rsync -av /etc/yum.repos.d/* root@server_one.usaga.com:/etc/yum.repos.d
Host key verification failed.
rsync error: explained error (code 255) at rsync.c(551) [sender=3.0.9]

正如我們在上面看到的那樣rsync失敗，因為密鑰指紋

yes所以在我們做了以下事情之後（關於 ssh的回答）

ssh root@server_one.usaga.com
The authenticity of host 'server_one.usaga.com (43.3.22.4)' can't be established.
ECDSA key fingerprint is 08:b1:c7:fa:c3:a8:8f:ce:85:4f:b9:ac:b1:8a:6a:87.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'server_one.usaga.com,43.3.22.4' (ECDSA) to the list of known hosts.

並rsync再次執行 - 它的作品

sshpass -p $password rsync -av /etc/yum.repos.d/* root@server_one.usaga.com:/etc/yum.repos.d
sending incremental file list
.
.
.

sent 378 bytes  received 112 bytes  326.67 bytes/sec
total size is 1937  speedup is 3.95

所以回歸到rsync

rsync為了忽略，需要設置哪些標誌key fingerprint？

或劑量rsync可以忽略關於 - Are you sure you want to continue connecting (yes/no)?是的問題

您可以為 rsync 指定其他遠端 shell，而不是使用 ssh -e，其中包括帶有額外選項的 ssh，因此添加-e "ssh -o StrictHostKeyChecking=no"會起作用。
