git 远程仓库的使用

上传到远程仓库

1.生成版本库

第一次上传要使用$ git init生成版本库
否则会产生如下报错
fatal: Not a git repository (or any of the parent directories): .git

2.连接到远程仓库

$ git remote add origin master  git@github.com:Bernicechl/git_study.git

可以使用’git remote -v’查看是否连接成功
3.第一次上传文件

$ git push -m origin master

出现如下错误

 To github.com:Bernicechl/git_study.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'git@github.com:Bernicechl/git_study.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

只要改为$ git push -f origin master即可解决问题
此后，每次本地提交后，只要有必要，就可以使用命令git push origin master推送最新修改

ps:如果出现
$ git remote add origin 提示错误 "fatal: remote origin already exists"
可能是由于系统已经配置过远程仓库？

使用$ git remote rm origin可以解决

从远程仓库克隆代码

$ git clone git@github.com:Bernicechl/git_study.git

一般ssh和http均可,但部分可能只支持其中一种
