这基本上是this question的后续行动。购买Comodo SSL证书后，我还只在zip文件夹中发送了两个文件 - fake_domain.crt和fake_domain.ca-bundle。我见过的大多数参考文献都说我应该收到4个文件，例如COMODORSADomainValidationSecureServerCA.crt。
要将我的SSL证书上传到AWS负载均衡器，它需要私钥，公钥证书和证书链，所有这些都是PEM格式。私钥和证书很简单。对于链条，使用所提问题的答案 -
cat certfile.crt bundle.ca-bundle >> chain.crt
没用。 AWS回应时出现以下错误：
创建证书时出错 无法验证证书链。证书链必须以即时签名证书开头，然后依次是任何中间人。无效证书链中的索引是：1
将两个文件转换为PEM格式，然后连接也失败了。这是我使用的命令，然后将输出复制到AWS Certificate Chain字段：
openssl x509 -inform PEM -in fake_domain.crt; openssl x509 -inform PEM -in fake_domain.ca-bundle
如何为AWS负载均衡器正确创建证书链？
答案 0 :(得分：0)
证书链由您购买的证书类型决定。如果您从Comodo购买ssl证书，他们将发送.crt和.key文件，这些文件是证书正文和证书私钥。
证书链与该文件无关。您可以从Comodo获取ssl类型的证书链文件。例如，如果您从Comodo购买ositiveSSL / EssentialSSL SHA-256，则需要使用下面的证书链验证您的证书：
