GitHub创建项目并关联至本地项目

一、准备工作

• github账号一枚
• 安装过git

brew install git mac电脑使用终端安装git

• 能够访问gitHub网址

有些网络不知道为何访问不了，比如说我现在的网络，只能开了才能访问。。。

二、GitHub上创建项目

创建完成，这边没啥说明的，就按照流程走就OK了的

三、ssh关联

• 首先先查看ssh是否创建过

ls -al ~/.ssh

ps:主要文件是

id_rsa.pub
id_rsa

1.ssh无创建过情况，新增一个ssh

tianledeMacBook-Pro:.ssh xxx$ ssh-keygen -t rsa -b 4096 -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/xxx/.ssh/id_rsa.
Your public key has been saved in /Users/xxx/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:GclQHufCH02UArsAyeYiWvEsE11aOzLQqw6CLOu8F7Y [email protected]
The key's randomart image is:
+---[RSA 4096]----+
|  .+.o+.+...o.   |
|  o.*+ * *.o.    |
|   B+.+ O o..    |
|. = =o o * .     |
|+o =    S .      |
|*..o             |
|o+. o            |
|o .E             |
|.+o              |
+----[SHA256]-----+

ps:
1、邮箱改为自己的邮箱
2、输入完ssh-keygen -t rsa -b 4096 -C "[email protected]"
一路回车！一路回车！一路回车！不要设置密码，不然后面后面每次push和pull都会提示输入密码，会相当的麻烦
3、4096指的是密钥的长度，也可以是2048，肯定是越长越安全喽

• 复制id_rsa.pub里ssh key的值，也就是文件里的一大串，并在GitHub上绑定ssh

2.ssh有创建过情况

• 查看ssh使用情况，如原来的需要用在别的地方则可以使用https方式去连接远程仓库，要是还是不行，就删除原来的ssh，重新新建一个
  

ssh -T [email protected]

ps:
由于我这边是重新创建的ssh文件，所以这边提示成功

三、将本地项目上传绑定至远程仓库

tianledeMacBook-Pro:yongjiatong-parent xxx$ touch README.md
tianledeMacBook-Pro:yongjiatong-parent xxx$ git init
Reinitialized existing Git repository in /java/yongjiatong/yongjiatong-parent/.git/

Everything up-to-date

## 在GitHub创建仓库时没有添加README文件，先创建README.md文件
touch README.md

## Git初始化
git init

## 将文件存至暂存区
git add *

## 将暂存区内容提交到本地仓库
git commit -m "项目本地仓库上传"

## 连接远程仓库(SSH和HTTPS方式都行)
## 使用ssh方式
git remote add origin [email protected]:zjh793666062/yongjiatong-parent.git
## 使用https方式
git remote add origin https://github.com/zjh793666062/yongjiatong-parent.git

## 提交到远程仓库
git push -u origin master

ps：
git push 将当前分支推送至远程同名分支
git push origin [branch-name] 推送本地某分支至远程某分支
git push -u origin [branch-name] 推送本地某分支至远程某分支，并跟踪

## 这边会先报错，原因是远程仓库和本地仓库不匹配，需要先合并，再push
## 先拉取远程仓库master分支，再将本地仓库master分支代码push到远程
git pull --rebase origin master
git push -u origin master

这样就完成了GitHub创建项目并关联至本地项目的动作，有问题可以随时留言哦。
