服务端
本地搭建repo服务器的方法：
首先得确保本地的git能够正常使用，并下载一个repo可以正常运行
目录结构如下：
首先新建一个文件夹repo-server，并在其下新建两个目录，如上图所示
在manifest.git文件夹中执行 git init 初始化一个git 库并添加default.xml
其中比较重要的是manifest.git文件夹中的default.xml，该default.xml的内容如下：
其中fetch就是你在服务器端所在的位置，可以是远程的，也可以是本地的，我这里设置的是本地的
客户端与服务器同步就是依靠这个地址进行repo sync的
其中default标签是用来设置分支名和远端服务器默认名的
接下来的project标签就是你要通过repo来管理的git库位置了
添加完毕后执行git add -A添加到缓冲区，再通过git commit -m "Init"添加到仓库中去(这些都是基本的git操作，这里不做详述)
manifest.git的文件列表
project目录下git 项目建立
在project1目录下执行
git init
git add -A
git commit -m "project1 Init"
cd ..
git clone --bare project1 project1.git
查看project目录下，是否存在project1.git(project1的纯净仓库)
如果存在则删除 project1(服务端只保留git纯净仓库)
在project2目录下同样执行上述操作，获取project2.git
至此，服务端工作已经完成
客户端
在repo-client文件夹下执行
repo init -u server_path
这个server_path是default.xml所在的目录路径
我的server_path是/home/Neo/repo/repo-server/manifest.git
所以我应该执行：
repo init -u /home/Neo/repo/repo-server/manifest.git
如果提示下面的错误：
fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno 101] Network is unreachable
这说明网络连接有问题，而你确认你网络没有问题的话，那就多连几次吧，会好的(G.F.W)
结果如下：
[root@SVR6 repo-client1]# repo init -u /home/Neo/repo/repo-server/manifest.git/

添加完名字和邮件地址即可。
然后这个时候依旧没有代码，这是因为代码还只是存在git库中，需要执行repo syn
[root@SVR6 repo-client1]# repo sync

From /home/Neo/repo/repo-server/project/project2
* [new branch] master -> repo-server/master
这时进入project/project1中时通过git branch查看的时候确是no branch..
[root@SVR6 project1]# git branch
* (no branch)
那是因为没有从确定所取的分支，执行
[root@SVR6 repo-client1]#repo forall -c git checkout -b master remotes/m/master
... A new repo command ( 1.19) is available.
... You should upgrade soon:
cp /home/Neo/repo/repo-client1/.repo/repo/repo /bin/repo
HEAD is now at 789317b... create project1
HEAD is now at 707deec... create project2
[root@SVR6 repo-client1]#
这里为什么会是remotes/m/master呢，这是需要查看下，你可以通过repo forall -c git branch -a
[root@SVR6 repo-client1]# repo forall -c git branch -a
... A new repo command ( 1.19) is available.
... You should upgrade soon:
cp /home/Neo/repo/repo-client1/.repo/repo/repo /bin/repo
* (no branch)
remotes/m/master -> repo-server/master
remotes/repo-server/master
* (no branch)
remotes/m/master -> repo-server/master
remotes/repo-server/master
＃remotes/m/master是这个就是一个repo的清单库的分支，也就是当你在执行repo init -U [URL] -b [branch_name]的时候，-b参数后面的分支。如果你repo init的 时候，没有指定过-b参数。那么这里就会显示remotes/m/master．（m--manifest）
#repo-server/master清单库里的default.xml里面指定的单个git库的revision值
＃remotes/repo-server/master是远程分支
[root@SVR6 repo-client1]#
执行完repo forall -c git checkout -b master remotes/m/master之后再查看分支时：
[root@SVR6 repo-client1]# repo forall -c git checkout -b master remotes/m/master
... A new repo command ( 1.19) is available.
... You should upgrade soon:
cp /home/Neo/repo/repo-client1/.repo/repo/repo /bin/repo
Branch master set up to track remote branch master from repo-server.
Switched to a new branch 'master'

[root@SVR6 repo-client1]# repo forall -c git branch -a

... You should upgrade soon:
cp /home/Neo/repo/repo-client1/.repo/repo/repo /bin/repo

remotes/m/master -> repo-server/master
remotes/repo-server/master

remotes/repo-server/master
[root@SVR6 repo-client1]#
这样就完成了简单repo服务器的搭建
其中repo forall这个命令的意思是针对repo下所有的git库进行同样的操作
repo forall -c 后接git命令，比如说你要查看所有git库中的代码情况，可以执行repo forall -c git status
如果你要查看提交状态，可以执行repo forall -c git log --stat
[root@SVR6 repo-client1]# repo forall -c git log --stat
... A new repo command ( 1.19) is available.
... You should upgrade soon:

总结：repo其实就是许多Git仓库的总管理员，便于管理和操作的一个python脚本，如果不是很大型的项目，用一个git仓库就好了，如果项目多且大，需要分开管理，那还是使用repo来管理比较好
