无论 PowerCLI 的配置如何，由于证书无效，Connect-VIServer 无法连接

Question

正如标题所示，我正在尝试使用 PowerCLI 登录 VMWare vSphere 服务器。即使我跑了Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false -Scope AllUsers，当我尝试连接到服务器时，这就是我得到的：

Connect-VIServer -Server "foobar.server" -User ... -Password ...
Connect-VIServer : 3/30/2020 4:16:46 PM Connect-VIServer                Error: Invalid server certificate. Use Set-PowerCLIConfiguration to set the value for the InvalidCertificateAction option to Prompt if you'd like to connect once or to add a permanent exception for this server.
Additional Information: Could not establish secure channel for SSL/TLS with authority 'foobar.server'.
At line:1 char:1
+ Connect-VIServer -Server "foobar.server" -User ... -Passw ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : SecurityError: (:) [Connect-VIServer], ViSecurityNegotiationException
    + FullyQualifiedErrorId : Client20_ConnectivityServiceImpl_Reconnect_CertificateError,VMware.VimAutomation.ViCore.Cmdlets.Commands.ConnectVIServer

看起来配置如下：

Get-PowerCLIConfiguration

Scope    ProxyPolicy     DefaultVIServerMode InvalidCertificateAction  DisplayDeprecationWarnings WebOperationTimeout
                                                                                                  Seconds

User                                         Ignore
AllUsers                                     Ignore

为什么我无法连接到服务器？

如果您使用的是旧版本的 vCenter (5.5)，请尝试以下操作：

[System.Net.ServicePointManager]::SecurityProtocol =[System.Net.SecurityProtocolType]'Ssl3,Tls,Tls11,Tls12'
