linux在下软件太卡？手把手教你配置国内镜像源

ubuntu18.04 配置国内镜像源

修改配置文件

1. 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
   
   

2. 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

1. 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

2. 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.
   #
   #

           http://mirrors.cloud.aliyuncs.com/centos/$releasever/centosplus/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
    
   #contrib - packages by Centos Users
   [contrib]
   name=CentOS-$releasever - Contrib - mirrors.aliyun.com
   failovermethod=priority
   baseurl=http://mirrors.aliyun.com/centos/$releasever/contrib/$basearch/
           http://mirrors.aliyuncs.com/centos/$releasever/contrib/$basearch/
           http://mirrors.cloud.aliyuncs.com/centos/$releasever/contrib/$basearch/
   gpgcheck=1
   enabled=0
   gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
   
   
   

3. 最后运行更新缓存

   yum clean all
   yum makecache
