systemd-resolved关闭,关闭Ubuntu自带的dns解析服务
原来的 53 端口被 systemd-resolved 占用。想自行安装dns解析器,必须解除占用
编辑 resolved 服务文件
sudo vim /etc/systemd/resolved.conf
编辑文件

#DNS=
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#DNSOverTLS=no
#Cache=no-negative
#DNSStubListener=yes 将这行的注释拿掉,改为no保存,如下
DNSStubListener=no
#ReadEtcHosts=yes
重新链接 resolv.conf 文件
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
#s表示软链接
#f表示存在即覆盖
原来的 /etc/resolv.conf 也是一个软链接,链接的是:
/run/systemd/resolve/stub-resolv.conf -> /etc/resolv.conf
重启服务即可
systemctl restart systemd-resolved.service
