ssh 免密

1）删除“/Users/snakeninny/.ssh/known_hosts”中iOSIP对应的条目。
假设iOS的IP地址是iOSIP。编辑“/Users/snakeninny/.ssh/known_hosts”，找到iOSIP所在的那一行，如下：


iOSIP ssh-rsa hXFscxBCVXgqXhwm4PUoUVBFWRrN

完整删掉这一行。

2）生成authorized_keys。
在Terminal中执行如下命令：

snakeninnysiMac:~ snakeninny$ ssh-keygen -t rsa


Generating public/private rsa key pair.


Enter file in which to save the key (/Users/snakeninny/.ssh/id_rsa):


Enter passphrase (empty for no passphrase):


Enter same passphrase again:


Your identification has been saved in /Users/snakeninny/.ssh/id_rsa.


Your public key has been saved in /Users/snakeninny/.ssh/id_rsa.pub.
……


snakeninnysiMac:~ snakeninny$ cp /Users/snakeninny/.ssh/id_rsa.pub ~/authorized_keys
就会在用户目录下生成authorized_keys。

3）配置iOS。

在Terminal中执行如下命令：

FunMaker-5:~ root# ssh-keygen


Generating public/private rsa key pair.

Enter file in which to save the key (/var/root/.ssh/id_rsa):


Enter passphrase (empty for no passphrase):


Enter same passphrase again:


Your identification has been saved in /var/root/.ssh/id_rsa.


Your public key has been saved in /var/root/.ssh/id_rsa.pub.
……


FunMaker-5:~ root# logout
Connection to iOSIP closed.


snakeninnysiMac:iosreproject snakeninny$ scp ~/authorized_keys root@iOSIP:/var/root/.ssh


The authenticity of host 'iOSIP (iOSIP)' can't be established.


RSA key fingerprint is 75:98:9a:05:a3:27:2d:23:08:d3:ee:f4:d1:28:ba:1a.


Are you sure you want to continue connecting (yes/no)? 

yes


Warning: Permanently added 'iOSIP' (RSA) to the list of known hosts.
root@iOSIP's password:
authorized_keys                            100%  408    0.4KB/s   00:00
重新使用ssh命令进入iOS试试看，还需要输密码吗？此时，“make package install”真正变成了一次配置，一键安装，一劳永逸！

失败原因总结：

1.iOS端/var/root/.ssh 文件夹创建失败

解决方式：创建对应文件夹，重新 scp ~/authorized_keys root@iOSIP:/var/root/.ssh 即可
