rsync 无法使用 -o StrictHostKeyChecking=no 选项

rsync 无法使用 -o StrictHostKeyChecking=no 选项

下面的 rsync 可以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它就会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，并且当我将其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：

Rsync 不在-o其命令行上使用 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，您应该能够将上面的内容用双引号引起来，因为参数-e用单引号引起来。手册页还提到使用环境变量作为命令行选项RSYNC_RSH的替代方案。-e
