由于nginx监听了443端口,caddy监听其它端口,通过iptables dnat到caddy端口也能使用,但是caddy head会返回alt-svc包含监听的端口,通过使用docker桥接方式启动caddy可解决。
docker build安装caddy镜像:
1 2 3 4 5 6 7 | FROM debian:bullseye RUN apt update -y RUN apt install curl net-tools vim iputils-ping -y RUN curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | tee /etc/apt/trusted.gpg.d/caddy-stable.asc RUN curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | tee /etc/apt/sources.list.d/caddy-stable.list RUN apt update -y RUN apt install caddy |
1 | docker build --tag debian-caddy:v1 - < Dockerfile |
启动:
1 | docker run -d --name caddy-http3 -p 443:443 /udp --dns=172.17.0.1 --restart=always - v /etc/caddy : /etc/caddy - v /data/www .haiyun.me: /data/www .haiyun.me - v /acme/haiyun .me: /acme/haiyun .me debian-caddy:v1 caddy run -config /etc/caddy/Caddyfile |
caddy配置文件:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | { admin off auto_https off servers { protocol { experimental_http3 } } } tls /acme/haiyun.me/haiyun.me.cer /acme/haiyun.me/haiyun.me.key reverse_proxy https://www.haiyun.me { header_up X-Forwarded-For {remote_host} header_down -server } } |
nginx添加head:
1 | add_header Alt-Svc "h3=\":443\"; ma=86400,h3-29=\":443\"; ma=86400"; |
可通过编译curl支持http3测试。

方法一,使用openssl ngtcp2 nghttp3编译curl支持http3 quic:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | apt install build-essential autoconf libtool pkg-config git clone --depth 1 -b OpenSSL_1_1_1m+quic https: //github .com /quictls/openssl cd openssl/ . /config enable -tls1_3 --prefix= /usr/local/openssl make && make install cd ../ git clone https: //github .com /ngtcp2/nghttp3 cd nghttp3/ autoreconf - fi . /configure --prefix= /usr/local/nghttp3 -- enable -lib-only make && make install cd ../ git clone https: //github .com /ngtcp2/ngtcp2 cd ngtcp2/ autoreconf - fi . /configure PKG_CONFIG_PATH= /usr/local/openssl/lib/pkgconfig : /usr/local/nghttp3/lib/pkgconfig LDFLAGS= "-Wl,-rpath,/usr/local/openssl/lib" --prefix= /usr/local/ngtcp2 -- enable -lib-only make && make install cd ../ wget https: //github .com /curl/curl/releases/download/curl-7_80_0/curl-7 .80.0. tar .gz tar zxf curl-7.80.0. tar .gz cd curl-7.80.0/ LDFLAGS= "-Wl,-rpath,/usr/local/openssl/lib64" . /configure --with-openssl= /usr/local/openssl/ --with-nghttp3= /usr/local/nghttp3 --with-ngtcp2= /usr/local/ngtcp2 --prefix= /usr/local/curl make && make install LD_LIBRARY_PATH= "/usr/local/curl/lib/:/usr/local/openssl/lib/" /usr/local/curl/bin/curl -V |
方法二,通过quiche编译支持http3 quic:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | apt install build-essential cmake pkg-config curl --proto '=https' --tlsv1.2 -sSf https: //sh .rustup.rs | sh source $HOME/.cargo /env git clone --recursive https: //github .com /cloudflare/quiche cd quiche/ cargo build --package quiche --release --features ffi,pkg-config-meta,qlog mkdir quiche /deps/boringssl/src/lib ln -vnf $( find target /release -name libcrypto.a -o -name libssl.a) quiche /deps/boringssl/src/lib/ cd ../ wget https: //github .com /curl/curl/releases/download/curl-7_80_0/curl-7 .80.0. tar .gz tar zxf curl-7.80.0. tar .gz cd curl-7.80.0/ . /configure LDFLAGS= "-Wl,-rpath,$PWD/../quiche/target/release" --with-openssl=$PWD/.. /quiche/quiche/deps/boringssl/src --with-quiche=$PWD/.. /quiche/target/release --prefix= /usr/local/curl make && make install cp .. /quiche/target/release/libquiche .so /usr/local/curl/lib/ LD_LIBRARY_PATH= "/usr/local/curl/lib/" /usr/local/curl/bin/curl -V |
使用curl测试http3 quic:
1 | LD_LIBRARY_PATH= "/usr/local/curl/lib/:/usr/local/openssl/lib/" /usr/local/curl/bin/curl --http3 https: //www .haiyun.me -I |
使用中遇到的问题,quiche编译的curl下载一会后断流,openssl编译的curl下载速度很慢。
