linux修改源映象地址

1.1 CentOS修改yum源映象地址為:mirrors.163.com (也可以改為阿里雲映象)

1、首先備份系統自帶yum源配置檔案/etc/yum.repos.d/CentOS-Base.repo

[[email protected] yum.repos.d]#  mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

2、進入yum源配置檔案所在的資料夾

[[email protected] yum.repos.d]# cd /etc/yum.repos.d/

3、下載163的yum源配置檔案(CentOS7)

[[email protected] yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

1.2 Ubuntu修改apt-get源

1、首先備份系統自帶apt-get源配置檔案/etc/apt/sources.list

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

2、編輯源配置檔案/etc/apt/sources.list,替換內容為:

#阿里雲源
