我们服务器如果安装区块链或Jenkins等软件容易因为版本低造成问题
若git版本太低，则卸载重装

yum remove git
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.21.0.tar.gz
tar -xvzf git-2.21.0.tar.gz
cd git-2.21.0
make prefix=/usr/local/git all
make prefix=/usr/local/git install
执行上面两端命令时可能会出现缺少依赖的情况，依次百度寻找缺少的依赖并安装
echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
source /etc/bashrc
git --version
[root@git home]# git --version
git version 2.21.0
