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 –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
