Git-第四篇廖雪峰Git教程学习笔记（3）远程仓库，克隆远端库

1、本次连接的是gitHub仓库。

  1》创建SSH Key。

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

lfy@lfy-PC MINGW64 /c/fyliu/lfyTemp/gitLocalRepository/yangjie (master)
$ ssh-keygen -t rsa -C "12345678@qq.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/lfy/.ssh/id_rsa):
Created directory '/c/Users/lfy/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/lfy/.ssh/id_rsa.
Your public key has been saved in /c/Users/lfy/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:88888888888888888jY888888888I8 12345678@qq.com
The key's randomart image is:
+---[RSA 2048]----+
|   .......       |
|                 |
+----[SHA256]-----+

lfy@lfy-PC MINGW64 /c/fyliu/lfyTemp/gitLocalRepository/yangjie (master)
$

  2》将公钥添加到ssh key列表。

  3》在gitHub上创建一个新的库，然后使用命令将我们的本地库与之关联。

$ git remote add origin git@github.com:michaelliao/learngit.git

   添加后，远程库的名字就是origin，这是Git默认的叫法，也可以改成别的，但是origin这个名字一看就知道是远程库。

  4》将已经与远端库关联的本地库的内容推送到远端库。

$ git push -u origin master

   本地库的内容推送到远程，用git push命令，实际上是把当前分支master推送到远程。由于远程库是空的，我们第一次推送master分支时，加上了-u参数，Git不但会把本地的master分支内容推送的远程新的master分支，还会把本地的master分支和远程的master分支关联起来，在以后的推送或者拉取时就可以简化命令。

2、克隆远端库

$ git clone git@github.com:michaelliao/gitskills.git
Cloning into 'gitskills'...
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 3
Receiving objects: 100% (3/3), done.
