centos 源码安装最新Git

1. 安装依赖包

Git 的工作需要调用 curl，zlib，openssl，expat，libiconv 等库的代码，所以需要先安装这些依赖工具。在有 yum 的系统上（比如 Fedora）或者有 apt-get 的系统上（比如 Debian 体系），可以用下面的命令安装：

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

2. 下载&解压

建议下载地址：https://mirrors.edge.kernel.org/pub/software/scm/git/

wget https://www.kernel.org/pub/software/scm/git/git-2.21.0.tar.gz
tar -zxvf git-2.21.0.tar.gz
cd git-2.21.0

3. 编译安装

cd git-2.21.0
./configure --with-openssl=/usr/local/openssl
make prefix=/usr/local/git all
make prefix=/usr/local/git install
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc

4.检查git版本

git --version
# git version 2.21.0

5. bug: 在make这一步出错，错误代码：

openssl问题，自带的是OpenSSL 1.0.1e-fips 11 Feb 2013，把它升级到了openssl-1.1.0d。从新编译安装
