Linux服务器配置镜像，`暂时不能解析域名`报错解决

DSN配置参考来源：Blog

在使用sudo apt-get update时，由于默认的下载网站地址在国外，会出现下载失败，这里需要配置国内镜像

一、镜像配置

将/etc/apt/sources.list文件进行备份sudo cp /etc/apt/sources.list ./sources_copy.list，sudo vim /etc/apt/sources.list打开文件，将之前的东西删了，把清华的镜像复制进去

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-updates main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-backports main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-security main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-security main restricted universe multiverse

# 预发布软件源，不建议启用
# deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-proposed main restricted universe multiverse
# deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ trusty-proposed main restricted universe multiverse

修改后更新

sudo apt-get update
sudo apt-get upgrade

1.继续报错

出现如下类型报错，说明DNS没有配置好

W: 无法下载 https://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/focal/InRelease  暂时不能解析域名“mirrors.tuna.tsinghua.edu.cn”
W: 无法下载 https://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/focal-updates/InRelease  暂时不能解析域名“mirrors.tuna.tsinghua.edu.cn”

2.解决方法

sudo vi /etc/resolv.conf

在配置中加入：

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
#这里用的是阿里云的DNS服务器
nameserver 223.5.5.5  
nameserver 223.6.6.6
