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：

 
   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.

   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。
