🗣 Wd提问: http3 nginx

🤖 Ai回答:
To enable HTTP/3 support in Nginx, you need to use a custom build of Nginx with experimental support for QUIC (the protocol underlying HTTP/3)、As of Nginx 1.23.0, HTTP/3 is available as an experimental feature, and it requires BoringSSL (a fork of OpenSSL) for QUIC implementation.

🔧 Steps to Enable HTTP/3 in Nginx

1、Install Dependencies
Ensure your system has the necessary tools and libraries:
bash
sudo apt update
sudo apt install -y build-essential libpcre3 libpcre3-dev zlib1g zlib1g-dev libssl-dev

2、Download Nginx Source Code
Clone the Nginx repository and checkout a version that supports HTTP/3 (e.g., `1.23.0` or later):
bash
git clone https://github.com/nginx/nginx.git
cd nginx
git checkout nginx-1.23.0 or a later version

3、Patch Nginx (if needed)
Some versions may require a patch for QUIC support、Check the [Nginx GitHub repository](https://github.com/nginx/nginx) for any patches related to HTTP/3.

4、Compile Nginx with HTTP/3 Support
Configure Nginx with the `with-http_v3_module` and `with-http_ssl_module` options:
bash
./auto/configure with-http_v3_module with-http_ssl_module with-http_gzip_static_module with-openssl=../boringssl

Replace `../boringssl` with the path to your BoringSSL source code.
If BoringSSL is not already installed, you'll need to build it first:
bash
git clone https://boringssl.googlesource.com/boringssl
cd boringssl
mkdir build
cd build
cmake ..
make
sudo make install

5、Build and Install Nginx
bash
make
sudo make install

6、Configure Nginx for HTTP/3
Edit your Nginx configuration file (e.g., `/etc/nginx/conf.d/your-site.conf`) and add the following:
nginx
server {
listen 443 ssl http3;
server_name 65.hk;

ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/privkey.pem;
ssl_protocols TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;

location / {
proxy_pass http://backend;
}
}

`listen 443 ssl http3;` enables HTTP/3 on port 443.
Use a valid SSL certificate (e.g., from Let's Encrypt).

7、Test and Reload Nginx
bash
sudo nginx -t Test configuration
sudo systemctl reload nginx

🚨 Notes
Experimental Status: HTTP/3 support in Nginx is still experimental and may have bugs or incomplete features.
QUIC vs、TCP: HTTP/3 uses QUIC (a UDP-based protocol), so ensure your firewall allows traffic on UDP port 443.
Alternative Tools: If you need a more stable HTTP/3 solution, consider using Caddy (which has built-in HTTP/3 support) or Traefik.

If you encounter issues, check the Nginx logs (`/var/log/nginx/error.log`) for errors related to QUIC or SSL.
