CentOS7 - DNS寄存器每三次只成功一次。

Question

我有一个用于VDI的CentOS 7.2安装，它通过使用bash脚本自动连接到Microsoft2008 R2域(DC是2012年的R2)。使用命令"net ads join -U 'Administrator%Passw0rd'进行AD成功(使用"net ads testjoin“、"net ads info”和“wbinfo -u”验证)。DNS注册不成功。在连接期间直接进行的DNS注册与"DNS update failed!“失败。使用"net ads dns register -U 'Administrator%Passw0rd'”手动注册linux仅每三次成功一次：

[root@vW-CentOS7-001 administrator]# net ads dns register -U 'Administrator%Passw0rd'                                                                                                                                                       DNS Update for vw-centos7-001.lab.mycompany.ch failed: ERROR_DNS_UPDATE_FAILED

如果我在运行"net ads dns register“时定义特定的域控制器(-S)，以及在krb5.conf中定义master_kdc，则问题仍然存在。在Samba日志文件(“egrep -iR 'dns|register' /var/log/samba/")中没有任何关于dns或注册的内容。为什么它会三次失败两次？我要做什么，我不需要在我的脚本中注册它三次？

Answer 1

确保配置了多个DNS服务器

在DHCP_HOSTNAME=<hostname_of_machine>文件中添加/etc/sysconfig/network-scripts/ifcfg-eth0 (如果接口实际上是eth0)。

运行service network restart。

运行net ads join -U administrator命令。

此外，在/etc/host文件中，您能否确认127.0.0.1条目有您想要的主机名。例如，127.0.0.1 mymachine.mycompany.com mymachine
