ubuntu server18.04 更换默认源为阿里源-加速
Ubuntu安装完毕后,默认使用的是官方的源,在国内访问速度很慢,这里介绍更换为阿里云的源方法。
安装server时建议替换镜像源,可以提速
原镜像: http://cn.archive.ubuntu.com/ubuntu/ 更换为: http://mirrors.aliyun.com/ubuntu/ http://mirrors.cn99.com/ubuntu/
步骤如下:
1.备份源配置文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup
2.用编辑器打开源配置文件
sudo vim /etc/apt/sources.list
3.删除文件内容,更换为以下内容(也可使用其他源)
