Purpose

一个或多个服务或端点不可用时，可能会返回 HTTP 503 错误响应代码。例如，当 vSphere Web Client 服务正在运行时，vCenter Server 服务可能未运行或处于Stopped状态。

Resolution

要对此问题进行故障排除：

1.  运行以下命令，确认尝试使用具有 telnet 的 vSphere Web Client 访问 vCenter Server 的计算机是否已连接：

telnet vcenter\_fqdn 9443

1.  运行以下命令，检查 VCSA 上的分区是否具有足够的可用空间：

df -h  
\* 在 6.7 版本中，/storage/archive 分区应该已满，这是预期行为。有关详细信息，请参见 ["File system /storage/archive is low on storage space" on the VCSA 6.7 VAMI page][File system _storage_archive is low on storage space_ on the VCSA 6.7 VAMI page]

1.  使用以下命令确保 vCenter Server 服务正在运行：

service-control --status –all

\* 如果任何服务意外关闭，您可以通过运行以下命令来启动所有服务：

service-control --start –all

\* 如果 PSC 为外部，您可能还需要检查 PSC 上的服务。

有关如何停止/启动服务的详细信息，请参阅以下文章：

[How to Stop, Start or Restart vCenter Server 6.x Services][How to Stop_ Start or Restart vCenter Server 6.x Services]

[Stopping, Starting or Restarting VMware vCenter Server Appliance 6.x services][Stopping_ Starting or Restarting VMware vCenter Server Appliance 6.x services]

1.  确保 VCSA 具有足够的资源来处理请求，您可能需要使用 top 命令检查主机和 VCSA 上的 CPU/内存使用情况。
2.  如果所有 VC 服务均已启动且 Web Client 仍未打开，您可以在位于以下位置的 virgo 日志中找到有关该问题的更多详细信息：

Windows vCenter Server：C:\\ProgamData\\VMware\\vCenterServer\\logs\\vsphere-client\\logs\\

vCenter Server Appliance：/var/log/vmware/vsphere-client/logs/

另请查看位于以下位置的 vpxd.log 文件：  
Windows vCenter Server：C:\\ProgramData\\VMware\\vCenterServer\\logs\\vmware-vpx

vCenter Server Appliance：/var/log/vmware/vpxd
