所以我的问题就像标题所示。不过，我从本页尝试了以下建议（https://documentation.cpanel.net/display/ALD/Installation+Guide+-+Troubleshoot+Your+Installation#InstallationGuide-TroubleshootYourInstallation-Licenseerrors），但没有结果。CPanel/WHM未知许可证文件错误
1）curl -L http://cpanel.net/showip.cgi（在服务器上显示我的ip地址，用于verify.cpanel.net脚本），这里也可以验证...（http://verify.cpanel.net/index.cgi?ip=xxx.xxx.xxx.xx）（我不喜欢显示我的IP，但相信我它已被验证。）
2.）/ usr/local/cpanel/cpkeyclt 更新cPanel许可证...完成。 更新失败！ 错误消息： 许可证检查似乎已在运行。 构建cPanel的全局缓存...完成
因此，上述不起作用。
然后我尝试了这些命令。
3.）/ usr/local/cpanel/etc/init/stopcpsrvd然后/ usr/local/cpanel/scripts/upcp --sync尝试重新同步。
这似乎成功运行，但我仍然得到相同的错误。以下附件是我尝试登录WHM时收到的错误消息。
4.）然后我尝试运行rdate -s rdate.cpanel.net，如其他一些帖子中建议的那样，让时间匹配起来，然后当我运行（/ usr/local/cpanel/cpkeyclt）它似乎是时候并没有发生过任何事情。
查看cPanel许可证的日志（/ usr/local/cpanel/logs/license_log）我看到这个。
