github问题解决（持续更新中）

1、ssh: connect to host github.com port 22: Connection refused

从.ssh文件夹中新建文件名为config，内容为：

Host github.com
Hostname ssh.github.com
Port 443

2、解决 git 多用户提交切换问题

使用系统命令ssh创建rsa公私秘钥

C:\Users\fyp01> ssh-keygen -t ras -b 4096 -C "${邮箱}"
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\fyp01/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\fyp01/.ssh/id_rsa.
Your public key has been saved in C:\Users\fyp01/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:4JRe/U5MvaLkh2sCPEHUvK1RBQr9zTB8y338T77ZliE ********
The key's randomart image is:
+---[RSA 4096]----+
|     .o+ ..o.    |
|      .o+o= ..   |
|     .+ o=.B.o.. |
|     +.oo o+= ..o|
|     .o.So. = ...|
|      + .o = E .o|
|       o  + o .o+|
|        . .o   .*|
|         o.    +o|
+----[SHA256]-----+

生成完后，将生成的文件重命名

在c:/Users/${用户名}/.ssh/目录下
创建config文件并编辑

Host github.com
Hostname ssh.github.com
Port 443
User fyupeng
IdentityFile /C/Users/fyp01/.ssh/id_rsa_fyupeng

Host github.com
Hostname ssh.github.com
Port 443
User fyupeng-rnf
IdentityFile /C/Users/fyp01/.ssh/id_rsa_rnf

后面如果你想用A用户去发布A用户仓库，那只要在config文件上保留A，使用’#注释B的，然后在
C:\Users\f${}用户名\.gitconfig文件中，更改当前用户为A，当然也可以用A发布到B用户仓库，看个人习惯。
