我在 Centos 上遇到了这个错误。如何解决这个问题？

答案1
错误信息告诉您 - 您的名称服务器没有 A 记录。这意味着您可能托管自己的主名称服务器和辅助名称服务器，因此您还需要胶水记录。
Jul 12 12:01:00 ns1.ringochat.com bash[4728]: zone ringochat.com/IN: NS 'ns1.ringochat.com' has no address records (A or AAAA)
Jul 12 12:01:00 ns1.ringochat.com bash[4728]: zone ringochat.com/IN: NS 'ns2.ringochat.com' has no address records (A or AAAA)
在你的区域文件中，你需要添加类似
ns1.ringochat.com. IN A 192.168.123.231
ns2.ringochat.com. IN A 192.168.123.232
然后使用以下命令检查区域文件
named-checkzone ringochat.com /path/to/zonefile
如果它报告加载正常（对于您的胶水记录服务器可能出现“忽略区域外信息”）则再次编辑，增加您的序列号，然后重新启动绑定。
