文件位置写/home/try/.ssh/server_rsa,不使用默认值，我命名为server_rsa担心影响到git的key(因为我的git使用的是默认值)</p>
<p>
ssh-copy-id root@123.45.56.78（你的服务器ip），</p>
<p>
或这使用</p>

添加</p>
<p>
Host lisa 随便起的，好记就行</p>
<p>
HostName 188.166.225.189 你的服务器ip</p>
<p>
User root</p>
<p>
Port 9999（端口自定，推荐不加） （后两条我未曾用到，前三条足以）</p>
<p>
IdentityFile ~/.ssh/id_rsa 认证的key位置，如果已经传到服务器就不用这条了</p>
<p>
可实现使用 ssh lisa 来代替 ssh root@188.166.225.186的效果</p>
