使用sudo yum install git

出现问题

[root@GS04 pycorrector]# git pull
fatal: unable to access 'https://github.com/yaolinxia/pycorrector.git/': Peer's Certificate issuer is not recognized.

解决：https://blog.csdn.net/fenglailea/article/details/50041219

git config --global http.sslVerify false

继续有问题

(base) [root@GS04 yaolinxia]# git clone https://github.com/yaolinxia/pycorrector.git
正克隆到 'pycorrector'...
fatal: repository 'https://github.com/yaolinxia/pycorrector.git/' not found

配置用户名、邮箱

git config --global user.name "yaolinxia"

git config --global user.email "18860976931@163.com"

使用git-clone

克隆一个新项目

拉取远程最新的更新

需要进入该项目文件夹下使用git pull

查看远程库信息，使用git remote -v；
本地新建的分支如果不推送到远程，对其他人就是不可见的；
从本地推送分支，使用git push origin branch-name，如果推送失败，先用git pull抓取远程的新提交；
在本地创建和远程分支对应的分支，使用git checkout -b branch-name origin/branch-name，本地和远程分支的名称最好一致；
建立本地分支和远程分支的关联，使用git branch --set-upstream branch-name origin/branch-name；
从远程抓取分支，使用git pull，如果有冲突，要先处理冲突。

利用Git从本地上传到GitHub

第一步： 进入要所要上传文件的目录输入命令 “git init”

第二步： 创建一个本地仓库，使用命令 “git remote add origin git@github.com:yourName/yourRepo.git”
              youname是你的GitHub的用户名，yourRepo是你要上传到GitHub的仓库

第三步： 比如你要添加一个文件xxx到本地仓库，使用命令 “git add xxx”，可以使用“git add .”自动判断添加哪些文件

              然后把这个添加提交到本地的仓库，使用命令 ”git commit -m ”说明这次的提交“ “

              最后把本地仓库提交到远程的GitHub仓库，使用命令 ”git push origin master“

提交本地更新

git config --global user.email "18860976931@163.com"
git config --global user.name "yaolinxia"
git commit -a
git pull

远程拉项目到本地

git clone 复制项目地址

删除本地仓库

rm -rf  .git   #删除

问题

文件夹中存在大文件，比如数据等

解决

git rm --cached giant_file
# Stage our giant file for removal, but leave it on disk

git commit --amend -CHEAD
# Amend the previous commit with your change
# Simply making a new commit won't work, as you need
# to remove the file from the unpushed history as well

git push
# Push our rewritten, smaller commit
