文看懂 Nginx 中开启 IPv6，包含设置 IPv6 SSL证书。
#前置条件
Nginx 默认配置中已经开启了 IPv6。
即 listen [::]:80 default_server; server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
重启后，检查端口监听，发现已经监听在 :::80 上，即监听在 IPv6 的 80端口上。
# netstat -ntlp | grep nginx
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 29391/nginx: master
tcp6 0 0 :::80 :::* LISTEN 29391/nginx: master
参考文档 浏览器访问 IPv6 地址访问 IPv6 网站，验证是否访问成功。
如果访问失败，请检查 安全组是否开放 IPv6 的 80 端口 入请求的访问策略。

IPv4 中监听 HTTP 和 HTTPS 的配置是 listen 80;、listen 443 ssl;
IPv6 分别是 listen [::]:80; 、listen [::]:443 ssl;
server {
listen [::]:443 ssl http2;
listen [::]:80;
#填写绑定证书的域名
server_name 6.ipw.cn;
#证书文件名称
ssl_certificate ssl/6.ipw.cn_bundle.crt;
#私钥文件名称
ssl_certificate_key ssl/6.ipw.cn.key;
ssl_session_timeout 5m;
#请按照以下协议配置
ssl_protocols TLSv1.2 TLSv1.3;
#请按照以下套件配置，配置加密套件，写法遵循 openssl 标准。
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
ssl_prefer_server_ciphers on;
}重启后，检查端口监听，发现已经监听在 :::443 上，即监听在 IPv6 的 443 端口上。
# netstat -ntlp | grep nginx
