vmware center: 503 Service Unavailable (Failed to connect to endpoint: [N7Vmacore4Http20NamedPipeServiceSpecE:0x00007f7e040197a0] _serverNamespace = / action = Allow _pipeName =/var/run/vmware/vpxd-webserver-pipe)  (估计是重装能解决问题，证书过期问题)

解决

（1）enable ssh

（2）service-control --start vmware-vpxd

Command> shell
root@photon-machine [ ~ ]# service-control --status vsphere-client
StartPending:
 vsphere-client
root@photon-machine [ ~ ]# service-control --stop vsphere-client

Performing start operation on service vsphere-client...
Successfully started service vsphere-client
root@photon-machine [ ~ ]# service-control --status vsphere-client

重启vcenter后：

Command> service-control --status   #查看服务
Command> service-control --start --all   #尝试开启所有服务

其他：使用windows2012r2安装也是一样的结果：

等待了一会后，就可以正常进入 了：

可能原因：时间问题，修改时间后，重新安装解决问题。
