使用github

1.ssh認證
ubuntu執行：

ssh-keygen -t rsa

便會在id_rsa文件生成密鑰

root@u12045:/book/github/book-code# cat /root/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCbDTr9QXZZL33UpZFn3JE56D7PNP0PPp5krZaLK/kFlVLLIMp+1DV2BZmiKzCO9eCgHjuqiTs1NQxYtKPu5boVjzAKU8yIQa7RPhu8b/SbX5/mQ0Peo/+r8f8zoOYqs95sbSPjjVGKygT9ggaWWaDXM7ILLac+xVc2AtvB/mZzMbC1i9Y6GE2pvUuaW94qkeG2qRVFsQMv0akErEPfA39fW4dLLSQ6i1Rj2rP4/euzDccG2hpCjECy3NThuSvs3pfEJGSGbp6MgcUszpOWmseM5ivkfuDGN8qH7HPJe95/5zHFmqWhldRKSa2nLnbPrFvy0bKKc3owAi3R716ByTW9 root@u12045

拷貝密鑰內容到github的ssh裏面(設置裏面)

接着在ubuntu進行驗證

root@u12045:/book/github/book-code# ssh -T [email protected]
Hi bbmmdjejsjcc! You've successfully authenticated, but GitHub does not provide shell access.

在github上新建一個linux-c-prj倉庫
克隆該倉庫

git clone https://github.com/bbmmdjejsjcc/linux-c-prj

把要上傳的文件拷貝到該目錄下

root@u12045:/book/github/linux-c-prj# ls
README.md  imx6-linux-app1-2019.2.16

git add imx6-linux-app1-2019.2.16/
git commit -m "add linux-c"
git push
//第一次使用 git push origin master     以後使用 git push
