本地代码首次git提交到远程仓库

场景：本地新建了一个工程文件，写好代码以后，如何首次提交到github?

在Github上新建repo，比如说vagrant-xwiki 

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki
$ git remote -v
fatal: not a git repository (or any of the parent directories): .git

原因：项目不是一个git仓库，缺少.git文件

解决方法：初始化本地仓库，把代码的文件夹变成一个仓库，使用git init命令

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki
$ git init
Initialized empty Git repository in D:/sandbox/code/vagrant-xwiki/.git/

添加远程仓库，仓库URL可通过Github查看

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (master)
$ git remote add origin git@github.com:bin9wei/vagrant-xwiki.git

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (master)
$ git remote -v
origin  git@github.com:bin9wei/vagrant-xwiki.git (fetch)
origin  git@github.com:bin9wei/vagrant-xwiki.git (push)

运行git pull拉取代码发现报错，原来是Github默认分支叫main，不叫master。

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (master)
$ git pull

From github.com:bin9wei/vagrant-xwiki
 * [new branch]      main       -> origin/main
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> master

所以新建一个main分支。这时可以正常pull

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (master)
$ git checkout main
Switched to a new branch 'main'
Branch 'main' set up to track remote branch 'main' from 'origin'.

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git pull
Already up to date.

git add需要提交的文件

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git status
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .gitignore
        Vagrantfile
        apache-tomcat-9.0.69.tar.gz
        hibernate.cfg.xml
        pg_hba.conf
        provision.sh
        xwiki-platform-distribution-war-13.10.10.war

nothing added to commit but untracked files present (use "git add" to track)

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git add .gitignore

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git add Vagrantfile

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git add hibernate.cfg.xml

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git add pg_hba.conf

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git add provision.sh

git commit 带上有意义的commit message，说明你这个改动是什么

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git commit -m "init box"
[main ce0af91] init box

最后git push

bin9w@LAPTOP-ODF35RAF MINGW64 /d/sandbox/code/vagrant-xwiki (main)
$ git push
