![DNS主机名解析问题](https://linux22.com/image/202470/DNS%E4%B8%BB%E6%9C%BA%E5%90%8D%E8%A7%A3%E6%9E%90%E9%97%AE%E9%A2%98.png)
我之前设置的 Linux 服务器无法通过主机名解析:我无法通过主机名访问 ssh 或网站(端口 80,8834),只能通过 IP 访问
我认为我的 /etc/hosts 文件配置良好:
127.0.0.1 localhost
ip_server name_server.domain.corp name_server
我的 resolv.conf 是:
nameserver ip_dns_server_dc01
nameserver ip_dns_server_dc02
search domain.corp
请问有人可以帮助我吗?
提前致谢。
答案1
Per man resolv.conf
,该行的语法nameserver ...
是:
nameserver Name server IP address
Internet address of a name server that the resolver should
query, either an IPv4 address (in dot notation), or an IPv6
address in colon (and possibly dot) notation as per RFC 2373.
Up to MAXNS (currently 3, see <resolv.h>) name servers may be
listed, one per keyword. If there are multiple servers, the
resolver library queries them in the order listed. If no
nameserver entries are present, the default is to use the name
server on the local machine. (The algorithm used is to try a
name server, and if the query times out, try the next, until
out of name servers, then repeat trying all the name servers
until a maximum number of retries are made.)
基本上,所有这些行:
nameserver ip_dns_server_dc01
nameserver ip_dns_server_dc02
nameserver dns_service (AD-DC 01)
nameserver dns_service (AD-DC 02)
无效,因为ip_dns_server_dc01
不是 IPv4 地址(以点表示法)或 IPV6 地址(以冒号表示法)。
我怀疑您拥有的文件是从某些指令复制而来的,您打算将其替换dns_server
为 的 IP 地址DC 01
。
它应该看起来像:
nameserver 192.168.1.1
nameserver 1.1.1.1
nameserver 2606:4700:4700::1111
您已将问题从 编辑nameserver dns_service (AD-DC 01)
为nameserver ip_dns_server_dc01
。这个答案仍然适用。但有了这个新的resolv.conf
,您就更接近了,因为现在您有了一个可以用 IP 替换的可解析名称。如果您知道 的 IP 地址ip_dns_service_dc01
,您可以将服务器的 IP地址添加192.168.1.1 ip_dns_service_dc01
到您的服务器中/etc/hosts
,以使其正常工作。192.168.1.1
不过,如果您有 IP,您实际上应该将其放入resolv.conf
.
