Git链接到自己的Github（1）简单的开始

好长时间没上来弄东西了，今天回来先开始弄下Git，之后再继续写uboot与kernel的编译，在版本控制下更加宏观地观察每次的变化。

　　1、在ubuntu中安装git

$ sudo apt-get install git git-core

　　2、配置本机的git

$ git config --global user.name "abcd"
$ git config --global user.email abcd@efgh.com

　　3、生成密钥

$ ssh-keygen -t rsa -C "abcd@efgh.com" //邮箱同上

　　4、提交密钥

vim /home/linx/.ssh/id_rsa.pub //复制里面的密钥

　　到github网页中登陆自己的账号，然后再account setting中，找到SSH KEY讲复制的密钥加入（需要再次输入github的密码）

　　5、检验是否链接上了github

$ ssh git@github.com
//正常情况下，回显如下
PTY allocation request failed on channel 0
Hi plinx! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.

　　6、首次推送

$ mkdir tmp      //创建推送目录
$ cd tmp         //进入推送目录
$ git init       //设置该目录为推送
$ touch README   //生成readme
$ git add README //加入修改列表
$ git commit -m 'first commit' //递交修改声明
$ git remote add origin git@github.com:abcd/tmp.git //为远程Git更名为origin
$ git push -u origin master //推送此次修改

　　然后各种问题从这里开始了，以下谈一下解决的方法：

　　问题一：

ERROR: Repository not found.

　　这个问题是因为在你推送的github账户中，并没有这个Repository。

　　解决方法：

　　1）检查自己的github中的Repository，检查自己创建的目录，必须要两者一致；

　　2）先git clone下github中的Repository，然后再进行更改，这样就一定一致了。

　　问题二：

Agent admitted failure to sign using the key.
Permission denied (publickey)

　　这个问题是因为你的ssh key并没有加入到你想git的github账户的ssh key中，所以没有访问权限。

　　解决方法：

　　1）重新拷贝一份当前的~/.ssh/id_rsa.pub中的ssh key到github中添加;

　　2）先删除~/.ssh/in_rsa*文件，然后重新ssh-keygen一份sshkey来生成密钥，然后复制到github，接着ssh链接github来检验是否成功联通。

　　问题三：

//出现如下提示
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to ...

　　这个问题是因为，github中已经有了这个代码，不允许你覆盖它。

　　解决方法：

　　1）强制推送，一般不推荐！

$ git push -f

　　2）

$ git pull

　　然后将出现其他提示，具体意思是说branch与merge未指定，git无法选择要推送的分支。

　　可以通过修改 .git/config文件中的下列内容

[branch "master"]
    remote = origin
    merge = refs/heads/master

　　也可以直接命令行修改

$ git config branch.master.remote origin
$ git config branch.master.merge ref/heads/master

　　目前了解到的也就这三个问题了。

　　之后就可以成功得推送了。
