创建Github账户的sshkey

首先在本地生成公私钥：

 george@GeorgeMBP  ~  cd ./.ssh
 george@GeorgeMBP  ~/.ssh  ls
known_hosts
 george@GeorgeMBP  ~/.ssh 
 george@GeorgeMBP  ~/.ssh  ssh-keygen -t rsa -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/george/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/george/.ssh/id_rsa.
Your public key has been saved in /Users/george/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:u4MTYy5V+EgdLgfcUmEwpSRxAcx5iF5LpaCWj2gfCNo [email protected]
The key's randomart image is:
+---[RSA 2048]----+
|  .++BB*=.       |
|     . ...       |
+----[SHA256]-----+
 george@GeorgeMBP  ~/.ssh  ls
id_rsa      id_rsa.pub  known_hosts
 george@GeorgeMBP  ~/.ssh  cat id_rsa.pub
ssh-rsa AAAAB3NzaC1ycmVv7svIqhpL3 [email protected]
 george@GeorgeMBP  ~/.ssh 

在Github页面上创建sshkey，创建成功后的截图如下：

如何创建一个项目？

创建一个目录并进入，初始化：

george@GeorgeMBP  ~/Developer/GitRepos  mkdir git-test-project
george@GeorgeMBP  ~/Developer/GitRepos  cd git-test-project
george@GeorgeMBP  ~/Developer/GitRepos/git-test-project  git init
Initialized empty Git repository in /Users/george/Developer/GitRepos/git-test-project/.git/

在该目录下创建一个文件，添加，提交到本地仓库，如下：

 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  ls
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  vim readme.md
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  ls
readme.md
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  git add.
git: 'add.' is not a git command. See 'git --help'.
The most similar command is
    add
 ✘ george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  git add .
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master ✚  git commit -m "第一次提交命令测试！"
[master (root-commit) 751ac35] 第一次提交命令测试！
 1 file changed, 6 insertions(+)
 create mode 100644 readme.md
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master 

将本地仓库和远程仓库关联，并提交。需要注意的是提交前之前，必须在Github上创建对应的库，否则会报错：Repository not found。

george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  git remote add origin https://github.com/zhiyanzhiyu/git-test-project.git
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master 
 george@GeorgeMBP  ~/Developer/GitRepos/git-test-project   master  git push -u origin master
