![使用 rsync 与 GCP 的权限被拒绝公钥](https://linux22.com/image/744231/%E4%BD%BF%E7%94%A8%20rsync%20%E4%B8%8E%20GCP%20%E7%9A%84%E6%9D%83%E9%99%90%E8%A2%AB%E6%8B%92%E7%BB%9D%E5%85%AC%E9%92%A5.png)
我正在尝试使用 rsync 连接到 GCP 虚拟机。每次我这样做时,都会收到与权限相关的奇怪错误。
我检查了我的用户名是否属于 sudoers 组,因此我看不出问题出在哪里。我登录到我的 GCP 实例,该实例按照我的 Mac OS 用户名格式在 /home 下创建了一个用户目录,
以下是我一直尝试的命令以及结果...
C02YT3UDLVDL:proj-name j.lname$ ssh -i ~/.ssh/google_compute_engine
[email protected] The authenticity of host 'xx.xxx.xxx.xx (xx.xxx.xxx.xx)'
can't be established. ECDSA key fingerprint is
SHA256:JW7VfidHTsAtq8JjF9bEkdfIjdskIAadfs80.Are you sure you want to continue
connecting (yes/no)? yes Warning: Permanently added 'xx.xxx.xxx.xx' (ECDSA) to
the list of known hosts.
之后我尝试移动测试目录......
rsync -Pavz testDir/* xx.xxx.xxx.xx:/home/j.lname
并得到
ssh_exchange_identification: Connection closed by remote host
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.2]
再试一次得到:
$ rsync -Pavz testDir/* xx.xxx.xxx.xx:/home/j.lname/
The authenticity of host 'xx.xxx.xxx.xx (xx.xxx.xxx.xx)' can't be established.
ECDSA key fingerprint is SHA256:Q8kqWi3iyLno3Q8kqWi3iyLno3Q8kqWi3iyLno3.
ECDSA key fingerprint is MD5:ff:56:c3:21:cc:f1:a7:62:1b:72:bc:54:8e:f7:c8:1a.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'xx.xx.xx.xx' (ECDSA) to the list of known hosts.
yPermission denied (publickey).
編輯:
根据这里某人的建议,也尝试过
rsync -Pavz -e "ssh -i ~/.ssh/google_compute_engine" testDir/*
[email protected]:/home/j.lname/
那时得到了:
bash: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far)
[sender]
rsync error: error in rsync protocol data stream (code 12) at
io.c(226) [sender=3.1.3]
答案1
使用 rsync 时,您必须像使用 ssh 一样指定 ssh 密钥。这就是您被拒绝权限的原因。我们可以使用 -e 选项来做到这一点:
rsync -Pavz -e "ssh -i ~/.ssh/google_compute_engine" testDir/* [email protected]:/home/j.lname
编辑:
目标服务器上也应安装 Rsync 命令
答案2
需要补充的是,确保遇到此问题的任何人都能理解......您需要在源机器和目标机器上执行 ssh key-gen 过程。
这意味着确保源的 id_rsa.pub 的内容保存在目标~/.ssh/authorized_keys
文件夹中...并且...反之亦然(目标的 id_rsa.pub 保存到源中的相同位置)
对需要在公钥、私钥和authorized_keys文件夹上设置的chmod权限进行一些其他搜索,因为这显然也很重要。
