CentOS7上传文件至github

1. 安装

CentOS7: [root@k8s-master ~]# yum install -y git

Ubuntu: sudo apt-get install git（普通用户采用sudo,在root下可省略） 

2. 配置用户名，邮箱（告诉github你是谁）

[root@k8s-master ~]# git config --global user.name "hrr520gzr"
[root@k8s-master ~]# git config --global user.email "huangrr17@lzu.edu.cn"

3. 配置登录公钥，与github互联

[root@k8s-master ~]# ssh-keygen -t rsa -C "huangrr17@lzu.edu.cn"
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): # 回车不输入任何内容
Created directory '/root/.ssh'. 
Enter passphrase (empty for no passphrase): # 回车不输入任何内容
Enter same passphrase again: # 回车不输入任何内容
Your identification has been saved in /root/.ssh/id_rsa.  # 可以看出存放公钥的位置
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:lqR+hOt9obsVjEljwOrKiaHYHHmdK+FXNzRk4DxxWKg huangrr17@lzu.edu.cn
The key's randomart image is:

[root@k8s-master ~]# cat /root/.ssh/id_rsa.pub

注意：将 id_rsa.pub 中的内容（$ cat ~/.ssh/id_rsa.pub #此命令可查看key内容）粘贴到 Key 文本框中，随意输入一个 title**(不要有中文)**，点击 Add Key 即可。

4. 测试连接

[root@k8s-master ~]# ssh -T git@github.com
The authenticity of host 'github.com (13.250.177.223)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
RSA key fingerprint is MD5:16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,13.250.177.223' (RSA) to the list of known hosts.
Hi hrr520gzr! You've successfully authenticated, but GitHub does not provide shell access.
# 显示"Hi hrr520gzr! You've successfully authenticated, but GitHub does not provide shell access."表示连接成功。

5. 上传本地代码到远程仓库

# 进入你要上传文件的文件项目目录下，我的项目在test下
[root@k8s-master ~]# cd test/
[root@k8s-master test]# ls
anaconda-ks.cfg  k8s.sh  kube-flannel.yml  kubernetes-dashboard.yaml
# 初始化git
[root@k8s-master test]# git init
Initialized empty Git repository in /root/test/.git/
# 添加需要上传的文件，如果需要上传项目目录下的所有文件，可以采用 . 代替。
[root@k8s-master test]# git add .
# 远程添加 其中https://github.com/hrr520gzr/ebusiness为你仓库的地址。
[root@k8s-master test]# git remote add origin https://github.com/hrr520gzr/ebusiness
# 开始生成待上传的模型，“firstCommit”
[root@k8s-master test]# git commit -m “firstCommit”也可以改成其他的说明性的文字,最终会显示在 github 界面文件名的后边.
[master (root-commit) 17b766b] “firstCommit”

# 由于是第一次push项目，所以得先git pull下，生成路径
[root@k8s-master test]# git pull https://github.com/hrr520gzr/ebusiness

# 正式push项目，但是出现HTTP 503代码响应错误
[root@k8s-master test]# git push -u origin master
Username for 'https://github.com': hrr520gzr   
Password for 'https://hrr520gzr@github.com': 
fatal: unable to access 'https://github.com/hrr520gzr/ebusiness/': The requested URL returned error: 503

# 这是因为如果要对远程代码具有读和写的权限，有两种途径，一种是ssh,一种是用带有用户名的远程仓库地址进行push。这里只介绍第一种做法。
[root@k8s-master test]# git remote set-url origin ssh://git@github.com/hrr520gzr/ebusiness.git
# 其中此处该https为ssh开头的地址，github.com改为了git@github.com, hrr520gzr是你的用户名，ebusiness为你的项目名。
# 然后重新输入用户名和密码，一般第一次要求输入，后面无需重复。
[root@k8s-master test]# git push -u origin master

一般来说，新建仓库的时候，把README勾选上，它的作用可以看下面英文描述。

# 那么第一次上传过项目过后，没有必要再经过这么繁杂的上传程序了。
直接从第5步开始就行。
# 进入到需要上传项目的目录，并初始化git
[root@k8s-master test]# git init
# 添加该目录下的所有文件为git mode
[root@k8s-master test]# git add .
# 添加远程git地址，注意此处已经采用了ssh协议上传
[root@k8s-master test]# git remote add origin ssh://git@github.com/hrr520gzr/test.git
# 生成mode,名字可以随便取，最好有标识性。
[root@k8s-master test]# git commit -m “test”
# 先拉取README文件，生成路径。
[root@k8s-master test]# git pull ssh://git@github.com/hrr520gzr/test.git
# 开始上传，第一个项目后无需再输入用户名和密码
[root@k8s-master test]# git push -u origin master

6. 更新项目

# 如果本地项目文件，发生变化了，可以采用本地远程同步的方式更改，也可以采用单独文件上传提交的方式
# 比如，在test项目目录下，增加了nginx-deployment.yaml ,如果项目下的所有文件都有变动，那么可以采用同步的方式，或者采用git add .的方式重新上传一遍。
[root@k8s-master test]# git add nginx-deployment.yaml
# 用-m 标识上传者.
[root@k8s-master test]# git commit -a -m "gzr"
[master 3dbed3a] gzr
