我已使用letsencrypt为ubuntu上的最新nginx安装SSL证书。 设置很好,除了:
之外,效果很好我对SSL知之甚少,不知道发生了什么,但我怀疑: 我暂时为Apache安装了SSL证书,现在转移到Nginx以获得它的http / 2支持。由于nginx插件不稳定,我不得不自己安装证书,这就是我所做的:
在我的nginx配置(/etc/nginx/conf/default.conf
)中,我添加了:
server {
listen 80;
server_name [domain];
return 301 https://$host$request_uri;
}
server {
listen 443 http2;
listen [::]:443 http2;
server_name [domain];
ssl on;
ssl_certificate /etc/letsencrypt/live/[domain]/cert.pem;
ssl_certificate_key /etc/letsencrypt/live/[domain]/privkey.pem;
}
这有可能以某种方式打破链条吗?这里的正确方法是什么?
谢谢你们

1)对于强烈的Diffie-Hellman并避免Logjam攻击,请参阅this great manual。
您需要使用这些指令扩展您的nginx配置(在您生成dhparams.pem文件之后):
ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA';
ssl_prefer_server_ciphers on;
ssl_dhparam /etc/nginx/ssl/dhparams.pem;
2)对于正确的证书链使用fullchain.pem而不是cert.pem,请参阅this great tutorial了解详情。
你将获得A级:)
