CentOS下升级Git1.7.1升级到Git2.2.1

卸载CentOS自带的Git

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

yum remove git

1、安装准备

yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel asciidoc xmlto perl-devel perl-CPAN autoconf*

2、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

3、查看版本号

># git --version
>git version 2.2.1
