ubuntu18.04 配置国内镜像源
修改配置文件
- 手动更改
- 用你熟悉的编辑器打开
/etc/apt/sources.list，例如vi /etc/apt/sources.list - 以
ubuntu 18.04(bionic)为例把下列内容复制替换sources.list中的全部内容(使用阿里云镜像)：
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
- 一键更改 通过
wget获取配置文件（前提你的电脑得有wget，没有的话运行sudo apt-get install wget），例如获取ubuntu18.04的配置文件为例(使用腾讯云镜像)，阿里云镜像没有找到现成的配置文件，用腾讯云代替
wget -O /etc/apt/sources.list http://mirrors.cloud.tencent.com/repo/ubuntu18_sources.list
其他版本可在阿里云或者腾讯云镜像查看即可。
更新缓存
apt-get clean all
apt-get update
Centos7 配置国内镜像源
和ubuntu基本类似，只是文件路径稍有不同
- 下载新的
CentOS-Base.repo文件到/etc/yum.repos.d/例如：
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
- 或者使用
vi /etc/yum.repos.d/CentOS-Base.repo替换成一下内容
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.
