linux – 将无特权的非帐户用户ssh放到另一个框中？

ssh -l targetuser -i path/to/key targethost

但是像apache这样的非帐户用户呢？由于该用户没有可以编写.ssh目录的主目录,因此整个过程始终失败：

$sudo -u apache ssh -o StrictHostKeychecking=no -l targetuser -i path/to/key targethost
Could not create directory '/var/www/.ssh'.
Warning: PeRMANently added '<hostname>' (RSA) to the list of kNown hosts.
Permission denied (publickey).

我尝试使用-o UserKNownHostsFile = / dev / null并将$HOME设置为/ dev / null,并且这些都没有完成.我知道sudo可能会为我解决这个问题,但我正在努力避免需要手动配置服务器,因为此代码将部署在许多不同的环境中.

有任何想法吗？

以下是我尝试过的一些不起作用的例子：

$sudo -u apache export HOME=path/to/apache/writable/dir/ ssh -o StrictHostKeychecking=no -o UserKNownHostsFile=path/to/apache/writable/dir/.ssh/kNown_hosts -l deploy -i path/to/key targethost
$sudo -u apache ssh -o StrictHostKeychecking=no -o UserKNownHostsFile=path/to/apache/writable/dir/.ssh/kNown_hosts -l deploy -i path/to/key targethost
$sudo -u apache ssh -o StrictHostKeychecking=no -o UserKNownHostsFile=/dev/null -l deploy -i path/to/key targethost

最终,我将使用此解决方案作为apache用户运行rsync.
