引言

CentOS 7上git clone总是报错，如：

[vagrant@localhost ~]$ git clone --verbose http://github.com/danielflower/app-runner.git
Cloning into 'app-runner'...
fatal: unable to access 'http://github.com/danielflower/app-runner.git/': TCP connection reset by peer

解决方法：通过yum install的git版本太旧，升级git版本后解决了该问题。

CentOS版本：?CentOS Linux release 7.9.2009 (Core)

git旧版本：1.8.3.1

git新版本：2.28.0

卸载老版本git

sudo yum remove git

安装新版本git

1. 安装依赖

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

2. 下载git安装包

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.28.0.tar.gz

注：如果没有wget，先yum install wget

3. 解压安装

tar -zxf git-2.28.0.tar.gz
cd git-2.28.0/
sudo make prefix=/usr/local/git all
sudo make prefix=/usr/local/git install

4. 配置环境变量

echo "export PATH=$PATH:/usr/local/git/bin" >> ~/.bashrc
source ~/.bashrc

?5. git clone正常了

[vagrant@localhost ~]$ git clone https://github.com/danielflower/app-runner-home.git
