在 ssh/scp 上使用 -i 选项

在 ssh/scp 上使用 -i 选项

我想通过在 ssh 或 scp 命令行上指定 -i 选项来设置登录到我的 redhat 服务器的能力。我已经按照谷歌的步骤进行操作，但似乎不起作用。步骤是：

On server:
su myuser
ssh-keygen -t rsa
accept all defaults

copy the id_rsa files to the client machine
attempt to ssh to the server with
ssh -i id_rsa myuser@server

权限是-rw-------forid_rsa和-rw-r--r--for id_rsa.pub。我有什么遗漏的吗？在谷歌上找到有关此选项的信息非常困难。

使用 -v 选项的输出是这样的

答案1

听起来您创建了一个密钥，但没有在服务器上配置帐户来授权该密钥。

将 的内容复制id_rsa.pub到服务器并将其添加到~/.ssh/authorized_keys.

不要复制id_rsa到服务器，并对其进行保护。该文件包含私钥，服务器不需要看到它。

请注意，如果密钥存储在客户端上并在该目录中~/.ssh调用，客户端将自动使用它，因此您不需要使用命令行选项来指定它。id_rsassh-i
