git版本略低，引发的血案
原本部署在阿里云上的项目，准备放到内网jenkins上发布，配置完成后发版，jenkins变红了，详细错误信息如下
ERROR: Error cloning remote repo 'origin'

经查git版本为1.7过低了
所以卸载git，重装，yum用不了，yum升级
yum升级
1.-- 下载yum安装文件
sudo wget https://mirrors.edge.kernel.org/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
sudo wget https://mirrors.edge.kernel.org/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
sudo wget https://mirrors.edge.kernel.org/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
sudo wget https://mirrors.edge.kernel.org/centos/6/os/x86_64/Packages/python-urlgrabber-3.9.1-11.el6.noarch.rpm
sudo wget https://mirrors.edge.kernel.org/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
sudo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
2.-- 查看yum
rpm -qa |grep yum
rpm -qa |grep python-urlgrabber
PackageKit-yum-plugin-0.5.8-21.el6.x86_64
PackageKit-yum-0.5.8-21.el6.x86_64
yum-metadata-parser-1.1.2-16.el6.x86_64
yum-plugin-security-1.1.30-14.el6.noarch
yum-utils-1.1.30-14.el6.noarch
yum-rhn-plugin-0.9.1-48.el6.noarch
3.--卸载yum
sudo rpm -aq |grep yum|xargs sudo rpm -e --nodeps
sudo rpm -qa |grep python-urlgrabber|xargs sudo rpm -e --nodeps
3.--安装yum
sudo rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm
sudo rpm -ivh yum-*
4.清除原有缓存
sudo yum clean all
5.重建缓存，以提高搜索安装软件的速度
sudo yum makecache
6.更新系统
sudo yum update

RHEL更换yum源的 PYCURL ERROR 22错误解决方法

编译安装git
git --version
1.卸载旧版本git：
yum remove git
2. 执行命令：
yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker
3. 下载git,解压：
wget https://github.com/git/git/archive/v2.24.0.tar.gz
tar -zxf git-2.24.0.tar.gz
4. 进入解压后的git安装目录，编译，安装：
cd git-2.24.0
make prefix=/usr/local/git all
make prefix=/usr/local/git install
5. 编辑环境变量配置（给到所有用户）：
vim /etc/profile
export PATH=$PATH:/usr/local/git/bin
source /etc/profile
