Ubuntu14.04更换apt源以及CentOS7更换yum源

实验用的是Ubuntu14.04以及CentOS7

Linux自带的源速度太慢,甚至比不过一些国内的源

所以在这里更换阿里的源

Ubuntu

首先将配置文件备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

然后vim编辑

sudo vim /etc/apt/sources.list

将原来的内容全部删除然后写入以下内容

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

更新源列表

sudo apt-get update

更新软件

sudo apt-get upgrade

完成

注:有时候apt-get update 更新的时候会报错

错误一:
W: Unknown Multi-Arch type ‘no’ for package ‘compiz-core’

W: Unknown Multi-Arch type ‘no’ for package ‘compiz-gnome’

解决方法是:

sudo apt-get install -f apt

错误二:
W: GPG error: http://dl.google.com stable Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 6494C6D6997C215E

解决方法:

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 6494C6D6997C215E

上述命令中的6494C6D6997C215E要与报错的一致

然后

apt-get update

CentOS7

登陆root帐号

cd /etc/yum.repos.d

删掉文件夹内的原有文件

rm -rf *

下载阿里源的repo文件

wget http://mirrors.aliyun.com/repo/Centos-7.repo

清理软件源

yum clean all

建立本地缓存

yum makecache

升级所有包同时也升级软件和系统内核

yum update

若想只升级所有包,不升级软件和系统内核,可以用

yum upgrade
