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。
