简介

早上把nanppi r2s换成了ubuntu core 改了静态ip发现dns不能生效

操作

看了下/etc/resolv.conf

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "systemd-resolve --status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
options edns0

This file is managed by man:systemd-resolved(8)

那就知道了,找了一下,配置文件在这里/etc/systemd/resolved.conf

#DNS=
#FallbackDNS=

重启systemd-resolved服务

systemctl restart systemd-resolved.service

ping 下百度发现可以解析了

看下systemd-resolved状态

systemd-resolve --status

显示
