git pull的默认地址

当git clone之后，直接git pull它会自动匹配一个正确的remote url

是因为在config文件中配置了以下内容：

[branch "master"]2     remote = origin3     merge = refs/heads/master

表明：

1.git处于master这个branch下时，默认的remote就是origin；

2.当在master这个brach下使用指定remote和merge的git pull时，使用默认的remote和merge。

 

但是对于自己建的项目，并用push到远程服务器上，并没有这块内容，需要自己配置。

如果直接运行git pull，会得到如此结果：

 

$ git pull 2 Password: 3 You asked me to pull without telling me which branch you 4 want to merge with, and 'branch.master.merge' in 5 your configuration file does not tell me, either. Please 6 specify which branch you want to use on the command line and 7  try again (e.g. 'git pull <repository> <refspec>'). 8 See git-pull(1) for details. 9 10 If you often merge with the same branch, you may want to11 use something like the following in your configuration file:12 13     [branch "master"]14     remote = <nickname>15     merge = <remote-ref>16 17     [remote "<nickname>"]18     url = <url>19     fetch = <refspec>20 21 See git-config(1) for details.

在参考[2]中，有这样一段：

Note: at this point your repository is not setup to merge _from_ the remote branch when you type 'git pull'. You can either freshly 'clone' the repository (see "Developer checkout" below), or configure your current repository this way:

git remote add -f origin login@git.sv.gnu.org:/srv/git/project.git2 git config branch.master.remote origin3 git config branch.master.merge refs/heads/master   

 

因此通过git config进行如下配置：

  $ git config branch.master.remote origin2   $ git config branch.master.merge refs/heads/master

或者加上--global选项，对于全部项目都使用该配置。
