通过修改/etc/resolv.conf配置文件,即可实现DNS的配置。
$ cat /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 "resolvectl 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 8.8.8.8 nameserver 8.8.4.4 options edns0
nameserver指定了DNS服务器的IP地址。修改此文件,保存后立即生效。
可以有很多行的nameserver,每一个带一个IP地址。在查询时就按nameserver在本文件中的顺序进行,且只有当第一个nameserver没有反应时才查询下面的nameserver。
Linux上修改DNS,比Win系统简单灵活。
