安裝需求：

># yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc
># yum install  gcc perl-ExtUtils-MakeMaker   
解除安裝Centos自帶的git1.7.1:

通過git –version檢視系統帶的版本，Cento6.5應該自帶的是git版本是1.7.1

># yum remove git
下載git2.2.1並將git新增到環境變數中

># wget https://github.com/git/git/archive/v2.2.1.tar.gz
># tar zxvf v2.2.1.tar.gz
># cd git-2.2.1
># make configure
># ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv
># make all doc
># make install install-doc install-html
># echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
># source /etc/bashrc

安裝出現問題：

/bin/sh: line 1: xmlto: command not found
make[1]: *** [git-add.1] Error 127
make[1]: Leaving directory `/root/src/git/Documentation'
make: *** [doc] Error 2

4.2 安裝xmlto
yum install xmlto

檢視版本號
># git --version
>git version 2.2.1
