安装需求：

># yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc ># yum install gcc perl-ExtUtils-MakeMaker error: ```/utf8.c:463: undefined reference to `libiconv'``` ># 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 && make install 

卸载Centos自带的git1.7.1:

通过git –version查看系统带的版本，Cento6.5应该自带的是git版本是1.7.1

># yum remove git 

下载git2.2.1并将git添加到环境变量中

># 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 

查看版本号

># git --version >git version 2.2.1
