在用yum安装gcc的时候,报了错误:
[root@001 ~]#yum -y install gcc gcc-c++ kernel-devel Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile There are no enabled repos. Run "yum repolist all" to see the repos you have. To enable Red Hat Subscription Management repositories: subscription-manager repos --enable <repo> To enable custom repositories: yum-config-manager --enable <repo>
1、检查是否断网
ping www.baidu.com
2、如果没断网,则说明是yum镜像没有了,需要下载一个:
cd /etc/yum.repos.d mv CentOS-Base.repo CentOS-Base.repo.backup wget http://mirrors.163.com/.help/CentOS6-Base-163.repo mv CentOS6-Base-163.repo CentOS-Base.repo yum clean all
