Ubuntu在域名解析时最直接使用的是/etc/resolve.conf文件它是/run/systemd/resolve/resolve.conf的软链接而对于刚装完的ubuntu系统该文件的内容如下
ubuntuip-172-31-36-184:/etc$ cat 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 directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# 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 172.31.0.2

#ReadEtcHostsyes个人猜测这个时候系统在往/run/systemd/resolve/resolv.conf里面写域名解析服务器地址的时候会从/etc/systemd/resolved.conf中取得DNS相关的配置。 2重启域名解析服务systemctl restart systemd-resolvedsystemctl enable systemd-resolved3备份当前的/etc/resolve.conf并重新设置/run/systemd/resolve/resolv.conf 到/etc/resolve.conf的软链接mv /etc/resolv.conf /etc/resolv.conf.bakln -s /run/systemd/resolve/resolv.conf /etc/验证
