Nginx 配置证书报错 nginx: [warn] "ssl_stapling" ignored, issuer certificate not found for certificate
nginx -t
nginx: [warn] "ssl_stapling" ignored, issuer certificate not found for certificate "ssl/mywebsite.de.pem"
CloudFlare SSL/TLS 源服务器，创建的证书，配置后报错。因为缺少了根证书。
将 https://developers.cloudflare.com/ssl/origin-configuration/origin-ca#cloudflare-origin-ca-root-certificate 中的根证书信息添加到 ssl/mywebsite.de.pem 后面即可。
curl https://developers.cloudflare.com/ssl/static/origin_ca_ecc_root.pem >> mywebsite.de.pem
