centos7安装git

1.安装git依赖包

yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

2.删除已有的git

yum remove git

3.下载git

　　在usr/src目录下

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.8..tar.gz

　　解压

tar -zxvf git-2.8..tar.gz

　　进入git-2.8.3目录，配置git安装路径

./configure prefix=/usr/local/git/

　　编译并安装

make && make install

4.将git指令添加到bashrc中

vi ~/.bashrc

　　在最后一行添加

export PATH=$PATH:/usr/local/git/bin

　　让配置立即生效

source ~/.bashrc

　　由于升级了git版本，git clone的时候报了如下错误

fatal: unable to access 'https://github.com/google/glog.git/': SSL connect error

　　可靠的解决办法

yum update -y nss curl libcurl
