准备：

（1）注册Github账号

（2）下载Github for Mac客户端并登录

这个时候可以从Github上Clone in Desktop ，把工程clone到电脑上，但是不能够把新建的工程上传到Github。还需要配置一些东西。

我们用Github的时候，常用的功能：下载，上传，修改，分支，多人合作开发，查看历史纪录，回到某一个时间节点开发。。。。

The most commonly used git commands are:

add Add file contents to the index

bisect Find by binary search the change that introduced a bug

branch List, create, or delete branches

checkout Checkout a branch or paths to the working tree

clone Clone a repository into a new directory

commit Record changes to the repository

diff Show changes between commits, commit and working tree, etc

fetch Download objects and refs from another repository

grep Print lines matching a pattern

init Create an empty Git repository or reinitialize an existing one

log Show commit logs

merge Join two or more development histories together

mv Move or rename a file, a directory, or a symlink

pull Fetch from and integrate with another repository or a local branch

push Update remote refs along with associated objects

rebase Forward-port local commits to the updated upstream head

reset Reset current HEAD to the specified state

rm Remove files from the working tree and from the index

show Show various types of objects

status Show the working tree status

tag Create, list, delete or verify a tag object signed with GPG

1. 检查SSH keys是否存在

命令行：ls -al ~/.ssh

chuuchuanwenchuangdeiMac:~ developer$ ls -al ~/.ssh
total 64
drwx------ 8 developer staff 272 4 16 15:59 .
drwxr-xr-x+ 25 developer staff 850 4 15 11:47 ..
-rw-r--r--@ 1 developer staff 6148 4 16 15:59 .DS_Store
-rw------- 1 developer staff 1766 3 20 18:29 github_rsa
-rw-r--r-- 1 developer staff 404 3 20 18:29 github_rsa.pub
-rw------- 1 developer staff 1675 4 16 15:55 id_rsa
-rw-r--r--@ 1 developer staff 422 4 16 16:18 id_rsa.pub

-rw-r--r-- 1 developer staff 1199 4 15 11:47 known_hosts

如果有文件id_rsa.pub 或 id_dsa.pub，表示ssh key存在。

命令行： ssh-keygen -t rsa -C “你的邮箱（abc@.xx.com）”

chuuchuanwenchuangdeiMac:~ developer$ ssh-keygen -t rsa -C "abc@.xx.com"

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/developer/.ssh/id_rsa): /Users/developer/.ssh/id_rsa.pub
/Users/developer/.ssh/id_rsa.pub already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/developer/.ssh/id_rsa.pub.
Your public key has been saved in /Users/developer/.ssh/id_rsa.pub.pub.
The key fingerprint is:

通过这个命令行ssh-keygen -t rsa -C “你的邮箱（abc@.xx.com）”连接Github，生成public/private rsa key pair，提示你是否覆盖，选择y覆盖，然后提示你输入密码，最后提示你保存成功。

你可以通过/Users/developer/.ssh/id_rsa.pub.pub前往你的文件夹查看。
