Apache配置AWS API网关证书

Question

我创建了一个AWS API网关，并将其指向VPS。我希望能够对我的VPS启用客户端SSL身份验证。我在这里进行了AWS演练。我在API网关控制台中生成了一个PEM编码的证书，并将其复制到我的Apache web服务器。证书和/或vhost配置似乎导致Apache SSL模块中出现致命错误。

错误日志：

Apache vhost配置：

<VirtualHost *:443>
    ServerName example.com
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/example
    DirectoryIndex index.html
    SSLEngine on
    SSLCertificateChainFile ssl/ca.crt
    SSLVerifyDepth 1
    LogLevel info ssl:warn debug trace1
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

进一步的研究已经证明@Michael-sqlbot在这两方面都是正确的。在AWS API网关与第三方服务器端点通信之前，需要证书颁发机构的证书。
