Linux系统默认yum源速度慢,最好修改为国内的yum源,国内阿里、网易、中国科技大学等都是非常不错的,更新快,速度快,选择其一就好。下面说明如何使用。
mv /etc/yum.repos.d /etc/yum.repos.d.backup
CentOS 5 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo CentOS 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo CentOS 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache
yum 会把下载的软件包和header存储在cache中(默认路径/var/cache/yum/),而不自动删除。如果觉得占用磁盘空间,可以使用yum clean指令进行清除,更精确 的用法是yum clean headers清除header,yum clean packages清除下载的rpm包,yum clean all全部清除。
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
