1、将该虚拟机的网口设置成桥接模式(Bridged Adapter)，以确保主机可以ping通虚拟机：
2、在ubuntu虚拟机上安装ssh server：
<code>sudo apt-get install openssh-server</code>
3、找到ubuntu的IP地址，即可以通过在terminal输入：
<code>ifconfig</code>
会出现下面的东西：
找到拥有inet的那一行，后面的地址即为该虚拟机的IP地址。这里可以看到，该虚拟机的IP地址为10.66.182.88
4、在主机上同样安装ssh。安装好后为了连接虚拟机，可以进行如下操作：
<code>wubijiadeMacBook-Pro:~ wooka$ ssh wu@10.66.182.88 The authenticity of host '10.66.182.88 (10.66.182.88)' can't be established. ECDSA key fingerprint is SHA256:xxx. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '10.66.182.88' (ECDSA) to the list of known hosts. wu@10.66.182.88's password: Welcome to Ubuntu 14.04.5 LTS (GNU/Linux 4.4.0-31-generic x86_64) * Documentation: https://help.ubuntu.com/ System information as of Thu Oct 25 22:23:38 HKT 2018 System load: 0.0 Processes: 109 Usage of /: 17.3% of 8.50GB Users logged in: 1 Memory usage: 6% IP address for eth0: 10.66.182.88 Swap usage: 0% Graph this data and manage this system at: https://landscape.canonical.com/ New release '16.04.5 LTS' available. Run 'do-release-upgrade' to upgrade to it. Last login: Thu Oct 25 22:23:38 2018 from localhost wu@ubuntu:~$ ls</code>
这里ssh wu@10.66.182.88，wu为虚拟机的用户名
至此可以直接从主机访问虚拟机的文件了。通过输入exit可退出访问。
<code>wu@ubuntu:~$ exit logout Connection to 10.66.182.88 closed.</code>
5、然而，麻烦的是，每次主机访问虚拟机时都要输入密码。如何进行免密操作？
为主机和虚拟机共同建立一个共享的密码。
即，可输入ssh-keygen，产生一个public/private密码对。
<code>wubijiadeMacBook-Pro:~ wooka$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/Users/wooka/.ssh/id_rsa): y # 下面一行代表可否用另一个密码代替之前需要输入的密码，为了方便，可以省略直接回车。 Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in y. Your public key has been saved in y.pub. The key fingerprint is: SHA256:xxx wooka@wubijiadeMacBook-Pro.local The key's randomart image is: +---[RSA 2048]----+ |.o . o.. .o | |. + o..... o | |o..o .o.o.+ | |=o..+Eo+oo . + | |o+.oooooS = . | |..o.. .o . o o | | o o. . o o | |. . .o . o | | . .+ . | +----[SHA256]-----+</code>
现在，我们将pubilc key推送到虚拟机上，即
<code>ssh-copy-id wu@10.66.182.88 /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/Users/wooka/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys wu@10.66.182.88's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'wu@10.66.182.88'" and check to make sure that only the key(s) you wanted were added.</code>
现在，你控制ubuntu虚拟机的时候，就不需要输入密码了哦！
