ubuntu - Vagrant Master 和 Slave Boxes - SSH key 设置

Question

我正在尝试设置 ssh key 登录，所以我可以输入 ssh slave01没有密码就可以 ssh 进入从机，但我在这里设置时遇到了麻烦。 master 和 slave 是运行 Ubuntu 的 Vagrant box。

主框有以下设置

vagrant@vagrant-ubuntu-trusty-64:~$ ifconfig
          ...
          inet addr:192.168.33.10  Bcast:192.168.33.255

vagrant@vagrant-ubuntu-trusty-64:~$ cat /etc/hosts
...
192.168.33.10 master
192.168.33.12 slave01
192.168.33.13 slave02

vagrant@vagrant-ubuntu-trusty-64:~/.ssh$ cat id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDWx6Zj6BLkd/Dz1ZY/YdzeHC6LGhx+bCdciYerm7q2x7DEAerbdFEsU68Dugso5PbROVCs68fCkVRdNeD7sAzgU0F8MFXRaiWGJNE8TM4NpzaiVDsiVd0V7334YM3hdFmD9uEshh3avIhzqbogtx0gHGerwizAyoVIaOC/OZKhd4GgBuUZchGB569s0Y2D4RYERA004OtGxSo1WzFmwIx64SS4bKF1Y/mKxRaU+aDuZMsO5CpsJ/KSKuBsqL1CX3ygupgivulYENYkWiCnm9R4o/jLDutpmOekm4Es0TdfaXo5m8Xu3kLYd0sk4LjAmSFw05waa7dmpGm+KIRHGDWx vagrant@vagrant-ubuntu-trusty-64

从机如下设置

vagrant@vagrant-ubuntu-trusty-64:~$ ifconfig
...
          inet addr:192.168.33.12  Bcast:192.168.33.255

当我从 Master 的命令行运行以下命令时，它一直在询问密码。我不确定它为什么这样做。

vagrant@vagrant-ubuntu-trusty-64:~/.ssh$ ssh slave01
vagrant@slave01's password: 
Permission denied, please try again.
vagrant@slave01's password:

尝试使用 ssh-copy-id在机器之间移动您的 ssh key 。您可能没有设置正确的 chmod目录的权限。
