rsync 无法使用 -o StrictHostKeyChecking=no 选项

  • 772

下面的 rsync 工作并帮助将远程目录复制到本地主机

/bin/rsync -rv myremoteuser@myremotehost:/tmp/Deployments/ /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/

一旦我添加-o StrictHostKeyChecking=no它失败并出现以下错误：

/bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/
Unexpected remote arg: myremoteuser@myremotehost:/tmp/Deployments
rsync error: syntax or usage error (code 1) at main.c(1348) [sender=3.1.2]

我希望它能够工作并且当我将它放在双引号下时也能工作，如下所示：

"/bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/"
bash: /bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/: No such file or directory

以下是详细信息：

    -oRsync在其命令行上不采用 ssh选项。您必须将 ssh 选项放入传递给 rsync-e选项的 ssh 命令字符串中。就像是：

    /bin/rsync -rv -e 'ssh -o StrictHostKeyChecking=no' myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/

    正如您所提到的，您应该能够将上述内容用双引号括起来，因为-e参数是单引号。手册页还提到使用RSYNC_RSH环境变量作为-e命令行选项的替代方案。
