上传本地代码到github上

ubuntu环境
首先确定是否安装了Git管理工具

  sudo apt-get install git

我选择SSH方式,比较安全方便,只需一次配置
1- 使用ssh命令连接github.com的SSH服务，登录名为git@github.com(所有GitHub用户共享此SSH用户名)。

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ ssh -T git@github.com
The authenticity of host 'github.com (192.30.253.113)' can't be established.
 ...
Permission denied (publickey).

第一次连接,会报权限被拒绝的提示,因为在本机还没有完成SSH认证,我们需要得到一个KEY密钥去完成认证.

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ ssh-keygen -C "xxxxxxxxx@qq.com" -f ~/.ssh/github
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/wangxiong/.ssh/github.
Your public key has been saved in /home/wangxiong/.ssh/github.pub.
The key fingerprint is:
 ...
 

一条命令生成密钥.

查看密钥用cat命令或者gedit命令文本方式打开

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ gedit /home/wangxiong/.ssh/github.pub

那么Github上需要做什么呢?

个人设置 添加或者删除KEY 新增

在上面Title自定义,而Key是刚刚自动创建的github.pub里面的内容,是一段很长的内容,全部复制到上图的"Key"栏目里.

ubuntu下测试一下

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ ssh -T git@github.com
Hi xxxxx! You've successfully authenticated, but GitHub does not provide shell access.

^ V ^ 提示授权成功了,接下来可以用SSH通道进行项目push和pull!

Step one：建立git仓库
cd到你的本地项目根目录下，执行git命令，此命令会在当前目录下创建一个.git文件夹。

 wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git init
Reinitialized existing Git repository in /home/wangxiong/Public/GitHubRepository/PaPaPlayer/.git/

Step two:将项目的所有文件添加到仓库中

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git add .

Step three:提交

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git commit -m "第一次提交"
On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean

Step four:去github上创建自己的仓库

创建后

复制SSH的链接
Step five:将本地的仓库关联到github上

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git remote add origin git@github.com:shonegg/PaPaPlayer.git
fatal: remote origin already exists.

Step six:上传代码到github远程仓库

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git push -u origin master
Counting objects: 782, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (676/676), done.
Writing objects: 100% (782/782), 6.88 MiB | 1.42 MiB/s, done.
Total 782 (delta 140), reused 0 (delta 0)
To git@github.com:shonegg/PaPaPlayer.git
 * [new branch]      master -> master
Branch master set up to track remote branch master from origin.

OK,切换到github上现在可以看到刚刚提交的文件了!
如果用https方式提交,会要求输入用户名和密码!

每次本地文件有变动(删除或新增),都要先commit提交到本地仓库,然后push到服务端(远程仓库)分支上!

场景1:
我删除了某个文件,然后用add命令提示如下,选择git add --ignore-removal或者git add --all,前者是忽略删除,后者是处理删除这一动作.

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git add .
warning: You ran 'git add' with neither '-A (--all)' or '--ignore-removal',
whose behaviour will change in Git 2.0 with respect to paths you removed.
Paths like 'app/src/main/res/values/bilibili_strings.xml' that are
removed from your working tree are ignored with this version of Git.

* 'git add --ignore-removal <pathspec>', which is the current default,
  ignores paths you removed from your working tree.

* 'git add --all <pathspec>' will let you also record the removals.

Run 'git status' to check the paths you removed from your working tree.

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git add --all 

我要达到把本地仓库的对应文件删除掉这一效果,那么就用第二种方式

wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git add --all 
wangxiong@Dell:~/Public/GitHubRepository/PaPaPlayer$ git commit -m "添加README.md"
[master f6d54c5] 添加README.md
 4 files changed, 6 insertions(+), 43 deletions(-)
 create mode 100644 README.md
 create mode 100644 README.md~
 rewrite ScreenShots/Screenshot_2016-07-23-12-21-31.png (95%)
 delete mode 100644 app/src/main/res/values/bilibili_strings.xml

从终端提示,可以看出,提交到本地库后,有4个文件改变了,创建了2个文件README.md和README.md~(临时文件),重写了一个图片文件,删除了一个xml文件

---

说到这,Github上上传README.md的说明文件时,通常都会展现截图效果图,那这是如何做到的呢?

Github上的README.md文件是使用的Markdown语言编写的

Markdown插入图片的语法是 ![] (图片url)

1:在本地建立ScreenShots效果图的文件夹,将效果图放入
2:提交到github上

3:取图片地址,注意我点击的Download选项,如果有raw选项,点击raw!

raw

拷贝这个链接到md文件,就可以显示图片啦!

我用的Markdown编辑工具,是StackEdit,一个开源免费工具

效果:
