如何使用Nginx配置将80端口重定向到443端口

server {
    listen 80;
    listen [::]:80;  # 支持IPv6
    server_name example.com www.example.com;  # 替换为您的域名

    # 强制重定向到HTTPS
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;  # 支持IPv6
    server_name example.com www.example.com;

    # SSL证书配置
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;  # 替换为您的证书路径
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;  # 替换为私钥路径

    # 推荐SSL配置（增强安全性）
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers 'ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256';
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;

    # HSTS（可选但推荐）
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;

    # 网站根目录和其他配置
    root /var/www/html;
    index index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }
}

sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw reload

# 检查配置语法是否正确
sudo nginx -t

# 重新加载Nginx使配置生效
sudo systemctl reload nginx

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

server {
        server_name xxxx.com;  # 域名   
        listen 80;                         
        rewrite ^(.*) https://$server_name$1 permanent;     
    }  

server {
        listen 443 ssl;
        listen [::]:443 ssl ipv6only=on;

        ssl_certificate /etc/letsencrypt/live//fullchain.pem;
