bharathi-1397@bharathi-1397:~$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/local/bharathi-1397/.ssh/id_rsa):
/home/local/bharathi-1397/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/local/bharathi-1397/.ssh/id_rsa.
Your public key has been saved in /home/local/bharathi-1397/.ssh/id_rsa.pub.
The key fingerprint is:

接下来我从 .ssh/id_rsa.pub 复制内容并存储在远程机器上。
bharathikannan.r@172.20.2.7:~$ mkdir .ssh
bharathikannan.r@172.20.2.7:~$ vi authorized_keys
将复制的内容粘贴到 authorized_keys 中，但下次我尝试登录时它会询问密码，为什么？ ssh bharathikannan.r@172.20.2.7 bharathikannan.r@172.20.2.7 的密码:
为什么要问密码？ .我正确地按照步骤操作。我不知道为什么要问密码？
ssh -v bharathikannan.r@172.20.2.7
