linux yum下载很慢怎么办,Linux添加yum源,yum下载速度过慢

CentOS系统更换yum软件安装源(此处以网易为例)

第一步：备份你的原镜像文件，以免出错后可以恢复。

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

第二步：下载新的CentOS-Base.repo 到/etc/yum.repos.d/

wget-O /etc/yum.repos.d/CentOS-Base.repo

http://mirrors.163.com/.help/CentOS6-Base-163.repo

如果无法下载可copy下面的PS内容

第三步：修改gpgkey

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6，之前的用

“#” 注释

第四步：运行yum makecache生成缓存

yum clean all

yum makecache

本人亲测可以达到5M/s，实际情况根据个人网速。

PS:本日列出已经配置好的repo，大家可以直接复制内容到/etc/yum.repos.d/CentOS-Base.repo 即可使用。

# CentOS-Base.repo

#

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client. You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.
