[Linux]Ubuntu修改apt-get镜像地址提高下载速度

Ubuntu安装后默认使用的是Ubuntu.com作为资源下载地址,在国内软件包的下载速度奇慢,因此需要修改下载镜像站点地址。通常有两种方法可以修改apt-get的镜像地址以提高apt-get下载速度。

方法1.直接下载镜像的sources.list
方法2.手动修改sources.list


方法1.以163镜像为例,Ubuntu12.04

# curl -0 http://mirrors.163.com/.help/sources.list.precise
wget http://mirrors.163.com/.help/sources.list.precise
mv sources.list.precise sources.list

方法2.以163镜像为例,Ubuntu12.04

vi /etc/apt/sources.list
