Centos 为Nginx 搭建https

• Nginx 扩展模块
• certbot文档 看文档，文档是最新的

如果执行 "certbot --nginx" 自动配置失败了, 那么可以执行 "certbot certonly -d ajanuw.fun" 获取或更新证书，然后在你的nginx中导入证书

nginx.conf

server {
        # listen       80;
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        server_name www.ajanuw.fun;

        ssl_certificate /etc/letsencrypt/live/ajanuw.fun/cer.pem; # 
        ssl_certificate_key /etc/letsencrypt/live/ajanuw.fun/privkey.pem; #
        ssl_session_timeout 1d;
        ssl_session_cache shared:SSL:50m;
        ssl_session_tickets off;

        ssl_protocols TLSv1.2; 
        ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';
 ssl_prefer_server_ciphers on;

        add_header Strict-Transport-Security max-age=15768000;

        ssl_stapling on;
        ssl_stapling_verify on;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location / {
            root   html;
            index  index.html index.htm;
  }
}

下面是我最新的配置

• nginx version: nginx/1.17.3
• OpenSSL 1.0.2k-fips 26 Jan 2017
• 我的域名 ajanuw.xyz

1. 先查看下使用certbot生成的密匙

# ls /etc/letsencrypt/live/ajanuw.xyz/
cert.pem  chain.pem  dhparam.pem  fullchain.pem  privkey.pem  README

这个dhparam.pem是我在生成密匙后新添加的 curl https://ssl-config.mozilla.org/ffdhe2048.txt > ./dhparam.pem

2. 配置nginx.conf

        server {
                listen 80;
                listen [::]:80;
                server_name www.ajanuw.xyz;

                # redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
                return 301 https://www.ajanuw.xyz;
        }

        server {
                listen 443 ssl http2;
                listen [::]:443 ssl http2;

                ssl_certificate /etc/letsencrypt/live/ajanuw.xyz/cert.pem;
                ssl_certificate_key /etc/letsencrypt/live/ajanuw.xyz/privkey.pem;
                ssl_session_timeout 1d;
                ssl_session_cache shared:MozSSL:10m;
                ssl_session_tickets off;

                ssl_dhparam /etc/letsencrypt/live/ajanuw.xyz/dhparam.pem;

                ssl_protocols TLSv1.2 TLSv1.3;
                ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384;
                ssl_prefer_server_ciphers off;

                add_header Strict-Transport-Security "max-age=63072000" always;

                ssl_stapling on;
                ssl_stapling_verify on;

                ssl_trusted_certificate /etc/letsencrypt/live/ajanuw.xyz/fullchain.pem;
                
                // 填写你服务器的ip
                resolver 127.0.0.1;

                location / {
                        root   html;
                        index  index.html index.htm;
                        # proxy_pass http://127.0.0.1:3000;
                }

                #error_page  404              /404.html;

                error_page   500 502 503 504  /50x.html;
                location = /50x.html {
                        root   html;
                }
        }
