我想使用 .iso 将服务器上的 iso 文件复制到我的计算机上rsync。我使用了以下命令，但出了点问题，我不知道是什么。我已经检查了密钥文件和原始文件的位置。
rsync --progress -avz -e 'ssh -v -i ./.ssh/new_keys node@<ip_address>' node@<ip_address>:~/ubuntu-16.04.1-server-amd64.iso ./Downloads/Ubuntu_Server.iso
这是通过参数创建的日志-v。

答案1
我有同样的错误消息：
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(228) [sender=3.2.3]
问题：rsync未安装在目标系统上。
rsync在目标系统上安装后，一切运行都没有错误。
答案2
您只需要如下命令。
rsync --progress -avz -e 'ssh -v -i ./.ssh/new_keys' node@<ip_address>:~/ubuntu-16.04.1-server-amd64.iso ./Downloads/Ubuntu_Server.iso
所以删除node@<ip_address>表格-e ssh '-v -i ...'
答案3
就我而言，这样的命令
rsync -vaP -e "ssh -i ~/.ssh/id_rsa_test" ~/source/grafana-test-logs [email protected]:/mnt/test/logs
/mnt/test/logs拥有适当的权限后才能工作，所以我需要chmod/chown在远程服务器上
答案4
我遇到了这个问题（同样的错误消息 ID 不是同样的问题），
当我消除争论时，它就消失了--compress。在这种情况下，这将是-zin -avz。
