服务器端：
#yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-devel
##wget https://github.com/git/git/archive/v2.2.0.tar.gz
#tar zxvf git-2.2.0.tar.gz
#cd git-2.2.0
#make prefix=/usr/local all
#make prefix=/usr/local install #root用户运行
如果编译时提示错误：
LINK git-credential-store
libgit.a(utf8.o): In function `reencode_string_iconv’:
/opt/git-master/utf8.c:530: undefined reference to `libiconv’
libgit.a(utf8.o): In function `reencode_string_len’:

/opt/git-master/utf8.c:582: undefined reference to `libiconv_open’
collect2: ld 返回 1
make: *** [git-credential-store] 错误 1
解决办法：
cd /usr/local/src/
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar -zxvf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure -prefix=/usr/local/libiconv && make && sudo make install
然后回到git继续编译：
cd /usr/local/src/git-1.8.5
make configure
./configure --prefix=/usr/local -with-iconv=/usr/local/libiconv
make
make install
# git --version
git version 2.2.0
OK，说明安装成功!
下面来安装 gitosis
gitosis为Git用户权限管理系统,通过管理服务端的authorized_key文件来执行对用户权限的管理，是一个python模块包
yum install python python-setuptools
cd /usr/local/src
git clone git://github.com/res0nat0r/gitosis.git
cd gitosis
python setup.py install
OK gitosis 安装成功！
CentOS服务器安装 Git 2.2.0
