my centos /etc/httpd/conf.d/ssl.conf

中的

SSLProtocol all  -SSLv2

改为

SSLProtocol all -SSLv3 -SSLv2

SSL证书https在线测试，故障检测网站ssllabs评分较低和较高的原因分析

SSLCipherSuite EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DE

更进一步的提高 SSL 的安全性，支持 Forward Secrecy

This server‘s certificate chain is incomplete. Grade capped to B.

修改 centos /etc/httpd/conf.d/ssl.conf 中

SSLCertificateKeyFile /etc/letsencrypt/live/[FQDN]/privkey.pem
SSLCertificateFile /etc/letsencrypt/live/[FQDN]/fullchain.pem

爲

SSLCertificateKeyFile /etc/letsencrypt/live/[FQDN]/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/archive/[FQDN]/chain1.pem
SSLCertificateFile /etc/letsencrypt/live/[FQDN]/fullchain.pem

或者

SSLCertificateKeyFile /etc/letsencrypt/live/[FQDN]/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/[FQDN]/chain.pem
SSLCertificateFile /etc/letsencrypt/live/[FQDN]/fullchain.pem

添加了 chain1.pem 之后， ssllab 显示 A 评分了
