windows下的git与ssh

1. windows下安装msysgit

2. 生成rsa秘钥，位置可选择默认位置默认名字（或者自己指定位置后续通过配置文件配置），秘钥可以略过，一路按enter

ssh-keygen -t rsa -C "youremail@yourcompany.com"

ssh的默认寻找的路径是 ~/.ssh

3.把生成的一对秘钥中的公钥(*.pub)放到服务器上

4.第一次连接到服务器上的时候可能会提示如下信息

The authenticity of host 'mint.phcomp.co.uk (78.32.209.33)' can't be established.
RSA key fingerprint is 6a:de:e0:af:56:f8:0c:04:11:5b:ef:4d:49:ad:09:23.
Are you sure you want to continue connecting (yes/no)? no

fingerprint是服务端的公钥的摘要，是让你确定你是否要连接到该服务器，确定的话输入yes，否则输入no。这是为了避免中间人攻击

第一连接后将生成一个known_hosts，记录已经连接过的服务器。

如果处于某种正常原因（如服务器的ip地址变化了），再次进行连接时，会出现如下信息

某天机器又改IP了，ssh后，报：
mmt@FS01:~$ ssh  -o StrictHostKeyChecking=no  192.168.0.130
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
fe:d6:f8:59:03:a5:de:e8:29:ef:3b:26:6e:3d:1d:4b.
Please contact your system administrator.
Add correct host key in ~/.ssh/known_hosts to get rid of this message.
Offending key in ~/.ssh/known_hosts:38
Password authentication is disabled to avoid man-in-the-middle attacks.
Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.
Permission denied (publickey,password).

 注意这句
Add correct host key in ~/.ssh/known_hosts to get rid of this message.

可以在known_hosts文件中删除关于该主机地址的记录
