DNS 服务器将主机名 vCenter 映射到地址;<<>> DiG 9.9.6-P1 <<>> vCenter +short,;; global options: +cmd,;; 连接超时;无法访问任何服务器,似乎不是本地 IP 地址 (DNS server maps host name vCenter to address(es) ; <<>> DiG 9.9.6-P1 <<>> vCenter +short,;; global options: +cmd,;; connection timed out; no servers could be reached which seems to be not local ip address)。请更新设备 /etc/hosts 文件以正确访问 DNS 服务器,或使用正确的主机名映射更新设备 DNS 服务器。要检查 DNS 是否具有本地主机名记录,请在设备上本地执行“dig vCenter +short”,或在 Windows 计算机上执行“nslookup vCenter”(Please either update appliance /etc/hosts file to properly access DNS servers or update appliance DNS servers with the proper host name mapping. To check if DNS has record about local host name, please execute `dig vCenter +short` locally on the appliance, or `nslookup vCenter` on a windows machine)。
