我一直在努力几个小时,以在运行Ubuntu的计算机和cpanel Web主机之间建立SSH连接。我一一尝试了在互联网上找到的所有解决方案,但没有一个解决了我的问题。我总是收到这个“权限被拒绝(公共密钥)”。
我以所有可能的方式编辑了sshd_config。
当我运行命令:ssh -vvv user@server.com时,这就是我得到的:

请帮助我,你们是我最后的希望。
答案 0 :(得分:0)
这里也一样。
我收到尝试执行此消息的消息-ssh -v user1@192.168.1.20 -i ~/.ssh/my-keypair-1
我尝试将正确的权限设置为〜/ .ssh /和〜/ .ssh / authorized_keys 没有运气.. 我实际上有另一个用户在同一台计算机上使用另一个SSH密钥,该用户的SSH密钥配置完全相同!
现在尝试将近2天。
更新-最终找到了解决方案!
问题在于权限。
事实证明,SSH对权限非常挑剔,您需要做的就是(在您要连接的服务器中)
删除.ssh文件夹(在提示符下{rm -r ~/.ssh/
键入yes
,然后单击Enter)。
然后,不要自己创建.ssh文件夹,而是ssh-keygen
,不用担心它创建的那些新的私钥和公钥,可以自由删除它们。
最后,将CD插入.ssh文件夹(cd ~/.ssh/
)中并创建authorized_keys(nano authorized_keys
),然后将其粘贴到公共密钥中,单击CTRL + X(保存),然后键入字母y
,然后单击Enter。
PS -如果您想要更好的安全性,这意味着用户将无法使用密码而不是密钥登录,打开外壳并在其中键入sudo nano /etc/ssh/sshd_config
,滚动到最后一部分,然后粘贴
ChallengeResponseAuthentication no
PasswordAuthentication no
UsePAM no
PermitRootLogin no
PubkeyAuthentication yes
请确保其中没有#,因为#使它们仅是注释而不是实际命令。
如果您希望能够通过SSH进入root用户,只需从其中删除PermitRootLogin no
。
现在,单击CTRL + X
,键入字母y
,然后单击Enter。
几乎忘记了-执行sudo /etc/init.d/ssh restart
重新启动SSH服务器,以便您的配置生效。
您完成了!让我知道我是否犯了任何错误。
我已发表此评论,以便有此问题的其他人可以解决。
