如何安装CA根证书，而不是网站证书:(IE8, Win7)

When you bring up the certificate details you are looking at the website cert, and not the CA cert. The General tab will say, "This certificate cannot be verified..." You need to select the CA by clicking on the Certification Path tab, and selecting the top most cert in the path. It should have a red X icon, and should say, "This CA Root certificate is not trusted because..." Click the View Certificate button, and on this new General tab you should see, "This CA Root is not trusted..." This is the certificate that you want to import into the Trusted Root Certificate Authority.

一旦您导入了CA，您就不需要再导入常规的网站证书，该证书将与您刚刚导入的CA匹配，IE会将一切视为正常工作。您不需要以管理员身份运行IE，也不需要先将站点添加到可信站点。导入完成后需要重新启动IE。

下面是我如何让它在IE8中工作的:

Go to the website in question, https://xxx.yyy.com, for instance, Click through until you get to the Certificate error in the browser status line. View the cert, then from the Details tab, select Copy to File. Save to the desktop as xxx.cer, for example, Start, Run, MMC. File, Add/Remove Snap-In, Select Certificates, Click Add, My User Account, then Finish, then OK, Dig down to Trust Root Certification Authorities, Certificates, Right-Click Certificate, Select All Tasks, Import, Select the Save Cert from the Desktop Select Place all Certificates in the following Store, Click Browse, Check the Box that says Show Physical Stores, Expand out Trusted Root Certification Authorities, and select Local Computer there, click OK, Complete the Import, Check the list to make sure it shows up. You will probably need to Refresh before you see it. Exit MMC, Open Browser, select Tools, Delete Browsing History Select all but Inprivate Filtering Data, complete, Go to Internet Options, Content Tab, Clear SSL State, Close browser and reopen and test.

伙计，今天我花了几个小时来解决这个问题。无论我在IE 8中做了什么，问题仍然存在。IE安装的证书出现在客户端PC的“受信任的根证书颁发机构”中，但IE仍然报错。

以下是我发现的解决方案:

在web服务器上:

Win+R, MMC，回车。 文件，添加-删除管理单元，证书，添加，管理证书:我的用户帐户， 完成。 导航到“证书-当前用户/受信任的根证书颁发机构/证书”。 找到您的证书，右键单击All tasks / Export。 不，不要导出私钥 "DER编码二进制X.509 (.CER)" 将文件保存在某个地方。 将新创建的. cer文件传输到客户端PC上。

在客户端机器上:

Win+R, MMC, Enter. File, Add-Remove snap-in, Certificates, Add, Manage certificates for: my user account, Finish, OK. Navigate to "Certificates - current user / Trusted Root Certification Authorities / Certificates". Right-click on Certificates container, All tasks / Import Choose your .CER file you've transferred from the server machine. On the next screen, choose "Place all certificates in the following store", click "Browse", check "Show physical stores", then choose "Trusted Root Certification Authorities / Local Computer". Press "Finish" finally. In Internet Explorer: Tools - Delete browsing History, In Internet Explorer: Tools - Internet options - "Content" tab - Clear SSL state button.

您可以使用CertMgr将证书添加为受信任的发行者，如果是自签名的，则添加为根证书

CertMgr.exe /add CertificateFileName.cer /s /r localMachine root

请参阅微软的文档:

您需要确保自签名证书为您正在设置的域使用正确的通用名称。如果您要为多个域使用相同的证书，则需要为每个域拥有唯一的证书，或者如果您的所有ssl站点都是一个公共域的子域，则可以生成具有*.domainname.tld等通配符域的证书。

如果您没有在自签名证书中正确设置您的常用名称，那么Chrome和Firefox可能可以工作，但IE可能在每次加载站点时都无法找到该证书。在IE中，它看起来就像你已经添加了网站的证书，但实际上在页面加载时，它永远不会被找到。
