ssh免密码登陆

1.

$ssh-keygen -t rsa

#生成RSA密钥对

2.

$ssh-copy-id -i ~/.ssh/id_rsa.pub hostname

#输入完密码后，会有如下输出

Now try logging into the machine, with "ssh 'linux-kc7s'", and check in:

  ~/.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

3.

$ssh hostname
#访问目标
