遇到这个问题的时候，有两种解决方法！
方法1
使用清空命令 yum clean all 然后执行 yum groupinstall "Development Tools"
方法2
如果上述方法没有用，在执行如下命令
cd /etc/yum.repos.d sudo wget http://public-yum.oracle.com/public-yum-el5.repo cd /etc/pki/rpm-gpg/ sudo wget https://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5
执行完后，在安装
yum groupinstall "Development Tools"
