修改源地址

sed 使用 查看修改后的效果(文件内容实际未修改)
sed s/deb.debian.org/mirrors.aliyun.com/g /etc/apt/sources.list

添加 -i 参数,替换写入(文件内容修改)

sed -i s/deb.debian.org/mirrors.aliyun.com/g /etc/apt/sources.list

ubuntu

sed -i s/security.ubuntu.com/mirrors.aliyun.com/g /etc/apt/sources.list
sed -i s/archive.ubuntu.com/mirrors.aliyun.com/g /etc/apt/sources.list
sed -i s/cn.archive.ubuntu.com/mirrors.aliyun.com/g /etc/apt/sources.list

debian

sed -i s/deb.debian.org/mirrors.aliyun.com/g /etc/apt/sources.list
sed -i s/security.debian.org/mirrors.aliyun.com/g /etc/apt/sources.list

alpine

sed -i s/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g /etc/apt/sources.list

修改 DNS

添加 DNS 服务器地址

echo 'nameserver 47.107.125.41' >> /etc/resolv.conf

替换原有地址

假设原来 DNS 服务器 127.0.0.11,查看目前 DNS 设置

cat /etc/resolv.conf
sed -i s/127.0.0.11/47.107.125.41/g /etc/resolv.conf

使用该 DNS,会将上述源地址重定向至阿里云镜像,不提供可用性保证

如果运行,出现类似错误? sed: can't move '/etc/resolv.conf73UqmG' to '/etc/resolv.conf': Device or resource busy

尝试下面命令

echo "$(sed 's/127.0.0.11/47.107.125.41/g' /etc/resolv.conf)" > /etc/resolv.conf

修改 hosts

支持的 HOSTS
# ubuntu
server_name                archive.ubuntu.com;
server_name                security.ubuntu.com;
server_name                cn.archive.ubuntu.com;
# debian
server_name                deb.debian.org;
server_name                security.debian.org;
server_name                prod.debian.map.fastly.net;
server_name                debian.map.fastlydns.net;
# alpine
server_name                dl-cdn.alpinelinux.org;
# mirrors
server_name                mirrors.lidong.me;
server_name                mirrors.oonnnoo.com;

# hosts
sh -c "echo '47.240.113.45 security.ubuntu.com' >> /etc/hosts"
