[转] git pull的默认地址

转载于http://www.cnblogs.com/lbsx/archive/2010/10/16/1853193.html

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：

1 [branch "master"]
2     remote = origin
3     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：

 

 1 $ 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 to
11 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:

 

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

 

 

因此通过git config进行如下配置：

1   $ git config branch.master.remote origin
2   $ 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。
