/etc/resolve.conf

/etc/resolv.conf是一个DNS客户端配置文件，用于设置DNS服务器的IP地址和DNS域名，还包含了主机的域名搜索顺序。该文件通常由网络管理器自动生成，但也可以手动编辑。以下是一个示例/etc/resolv.conf文件的内容：

# 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 192.168.1.1
nameserver 8.8.8.8
search example.com

该文件包含以下内容：

- 以#开头的行是注释行，不会被解释器读取。
- nameserver行指定DNS服务器的IP地址。
- search行指定DNS域名的搜索顺序。

如果您需要更改DNS服务器或搜索域，请编辑此文件并保存更改。但是，请注意，如果您使用网络管理器，则可能会覆盖此文件。因此，最好使用网络管理器来更改DNS服务器和搜索域。
