我已经在hyper-v的 centos 上安装了 Apache Cloudstack 4.11 。按照以下步骤安装并尝试访问http://192.168.100.26:8080/client/后出现错误：
HTTP 错误 503 访问 /client/ 时出现问题。原因：服务不可用

或者也许时区是问题，但不知道如何解决它。
服务器时区值“EDT”无法识别或代表多个时区。如果要使用时区支持，您必须配置服务器或 JDBC 驱动程序（通过“serverTimezone”配置属性）以使用更具体的时区值。
谁能帮我解决这个问题？我完成了上面提到的指南中的确切步骤。操作系统 CentOs 7，可能堆栈 4.11
