场景：
1. 在没有服务器的情况下，几个人合作开发。 完全体现git分布式版本管理。每个人的git init example(不是用git --bare init example.git) 都可以作为分布式的节点。
2. 一般git教程都是推荐使用git --bare init example.git 来建立空仓库，集中式管理。
注意：
你要push到别人的机器上，需要经过别人机器的同意。需要在
被push的机器上：
git config receive.denyCurrentBranch warn
场景演练1：A:在master分支 ， B在master分支，都在master分支上
A机器上：
1. git init example
2. git touch README.md
3. git add .
4. git commit -m"first commit"
B机器上：
1. git clone [email protected]:/home/git/example
2. git touch 1.txt
3. git add .
4. git commit -m"add 1.txt"
5. git remote add origin [email protected]:/home/git/example
可能出现的问题：
1. Q: A怎么知道B已经push了?会不会当Apush后
A: A机器git status时，提示有modfy。但是这个modfy是在缓存里面的。而没有悄悄的覆盖工作目录。当你切换branch时，会自动的将缓存里的modfy恢复到master分支。
所以正确的工作方式：
1. 不能直接在master分支上进行操作，把master分支作为服务中心站。
2. 新建一个develop分支作为主要工作分支
git push origin master出现如下错误：

执行命令解决问题
git config receive.denyCurrentBranch ignore
git pull出现如下错误：
You asked me to pull without telling me which branch you
want to merge with, and 'branch.master.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.
If you often merge with the same branch, you may want to
use something like the following in your configuration file:
[branch "master"]
remote = <nickname>
merge = <remote-ref>
[remote "<nickname>"]
url = <url>
fetch = <refspec>
See git-config(1) for details.
执行命令：
$ git config branch.master.remote origin $ git config branch.master.merge refs/heads/master
