linux - 服务器之间的 SSH 登录仍然要求输入密码，为什么？

Question

我有两个服务器，标识为 server-1 - 192.168.3.128 和 server-2 - 192.168.3.130。我正在设置 capifony 以自动部署从 server-1 到 server-2，这是我到目前为止所做的:

1. 在两台服务器中，我都创建了一个没有密码的用户 deploy，因为我将使用该用户进行部署。
2. 在 server-1 中，我通过运行以下命令设置了 SSH key :ssh-keygen 并且没有密码短语和默认目录。
3. 我已将 server-1 的 /home/deploy/.ssh/id_rsa.pub 的内容复制到 server-2 的 /home/deploy/.ssh/authorized_keys。

4. 我尝试从服务器 1 通过运行 ssh deploy@192.168.3.130 访问服务器 2，它要求输入密码(下面是输出)

   $ ssh deploy@192.168.3.130
   The authenticity of host '192.168.3.130 (192.168.3.130)' can't be established.
   RSA key fingerprint is 3c:81:da:7a:78:0f:b0:2f:44:3b:62:fb:c9:6f:33:86.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added '192.168.3.130' (RSA) to the list of known hosts.
   deploy@192.168.3.130's password:
   

这是上面命令的 -v 输出:

为什么？我做错了什么？

Answer 1

除了在详细模式下运行客户端之外，在另一个端口上以 Debug模式启动一个新的服务器实例:

server-2 作为根:

# /usr/sbin/sshd -p 9999 -d

然后以详细模式连接到同一端口上的该服务器:

server-1 作为部署

$ ssh -vvv -p 9999 server-2

9/10 与权限有关。
