本地新建GitHub远程仓库SSH连接，git init 及 clone的操作记录

背景

公司电脑更换，本人原来在Github上的代码需要继续使用Git来维护，以下内容为我操作时的记录20180207，方便自己学习，同时也希望为其他有同样问题的朋友提供一点思路。

说明

## 表示注释说明
必要的终端命令已经用颜色标记

重新新建ssh连接

## 打开终端 尝试连接git

localhost% ssh -T [email protected]
The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,192.30.255.112' (RSA) to the list of known hosts.
[email protected]: Permission denied (publickey).

## 首先，清除现电脑中所有的key-pair
ssh-add -D
rm -r ~/.ssh

## 删除你在github中的public-key
## 在浏览器中登录github --> settings --> SSH and GPG keys 中删除原来的 

## 新建ssh-key 一般用你原先的邮箱账号
localhost% ssh-keygen -t rsa -C "[email protected]"

## 连续3次enter键可以不要密码
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/aidong/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 

Your identification has been saved in /Users/aidong/.ssh/id_rsa.
Your public key has been saved in /Users/aidong/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:GXqSfUeT34v+3wW1AbfzJ28kEZNxc8wIhNIwQMhd3yQ [email protected]
The key's randomart image is:
+---[RSA 2048]----+
|   . +oo+oEo+o+Oo|
|    o . .oo+ .=+*|
|        ... = .+.|
|       + o . o +=|
|      + S . . =.=|
|       o . .  .*o|
|             . .+|
|            .  .o|
|             ...+|
+----[SHA256]-----+

## 刚刚生成文件的位置
localhost% cd ~/.ssh
localhost% ls
id_rsa id_rsa.pub known_hosts

## vi 打开 id_rsa.pub 复制其中所有内容
localhost% vi id_rsa.pub 

## 在浏览器中登录github --> settings --> SSH and GPG keys 中添加刚刚复制的 ssk key 

## 再次尝试连接
localhost% ssh -T [email protected]

## 出现以下内容表示成功
Hi Sdfeidong! You've successfully authenticated, but GitHub does not provide shell access.

clone github账号下的已有项目

## cd 目标目录（ZJDTest） 
localhost% cd /Users/aidong/Desktop/Project/MyProject/GitHub/ZJDTest 
localhost% git clone git://github.com/xxxxxx/ZJDKit.git

Cloning into 'ZJDKit'...

## 提交 
## 打开项目修改后 cd 到目标目录
localhost% cd /Users/aidong/Desktop/Project/MyProject/GitHub/ZJDTest/ZJDKit 
localhost% git add .

## 添加提交信息
localhost% git commit -m "测试clone项目提交"
[master e8d71b2] 测试clone项目提交
 1 file changed, 1 insertion(+)
## 可以明显看出是修改了一个文件，新增了一行代码

## push提交
localhost% git push -u origin master

## 错误信息
fatal: remote error: 
  You can't push to git://github.com/xxxxxx/ZJDKit.git
  Use https://github.com/xxxxxx/ZJDKit.git

## 添加 origin
localhost% git remote add origin https://github.com/xxxxxx/ZJDKit.git    
fatal: remote origin already exists.
localhost% git remote rm origin
localhost% git remote add origin https://github.com/xxxxxx/ZJDKit.git

## 再次push提交 
localhost% git push -u origin master

## 第一次会让提示输入 github的 账号
Username for 'https://github.com': xxxxxx
## github的 账号密码 终端无提示
Password for 'https://[email protected]': 输入密码<终端无提示>

## 至此提交成功了

## 以后再提交步骤
##
cd 目标目录
git add .
git commit -m "更新内容说明"
git push -u origin master
## 打标签可有可无
git tag 0.2.0 
git push origin 0.2.0
## 完成

init github账号下的新建项目

## 先在github建一个空的项目，不再赘述

## cd 到你需要用Git管理的文件夹下
cd 目标目录
git init
git add README.md
git commit -m "first commit"
## 添加源 就是你刚刚github上的空项目地址
git remote add origin https://github.com/xxxxxx/ZJDTest.git
git push -u origin master
git tag 0.0.1
git push origin 0.0.1
## 完成
