centos6.8 git 安装

centos 6.8 默认git 1.7.1 版本过老，安装最新版本，通过源码编译安装

卸载Centos自带的git1.7.1:

yum remove git

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc

yum install  gcc perl-ExtUtils-MakeMaker

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

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

make install

ln -s /usr/local/git/bin/git /usr/bin/git

git version

git version 2.2.1
