一、为什么要换源
二、debian系列操作系统换源
(1)备份原来的源
(2)创建新的源
(3)更新apt软件源
三、红帽系列操作系统换源
(1)下载并替换
(2)生成yum缓存
(3)更新
(4)禁用盗版提示
一、为什么要换源
1.默认的软件包仓库都在国外,apt-get或者yum下载软件包很慢。换成国内的仓库源就快了;
2.redhat系统的yum源是要收费的,可以换成免费的centos的yum源。都是yum源是兼容的。
二、debian系列操作系统换源
(1)备份原来的源
sudo mv /etc/apt/sources.list /etc/apt/sources.list.backup
(2)创建新的源
sudo vim /etc/apt/sources.list
复制以下内容并保存(阿里云源):

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
(3)更新apt软件源
sudo apt-get update
三、红帽系列操作系统换源
当前是redhat操作系统,要换成阿里的centos8的yum源:
(1)下载并替换
cd /etc/yum.repos.d/
wget https://mirrors.aliyun.com/repo/Centos-8.repo
mv redhat.repo redhat.repo_bak //备份原来的yum源
mv Centos-8.repo redhat.repo //替换原来的yum源
(2)生成yum缓存
yum makecache //把yum源上所有包的信息下载到本地
(3)更新
yum -y update //-y选项是下载过程中对所有提问都回答yes
(4)禁用盗版提示
修改以下两个文件的Enable=0来禁用Subscription Management的提示
vim /etc/yum/pluginconf.d/product-id.conf
vim /etc/yum/pluginconf.d/subscription-manager.conf
