We started test builds for nginx with http v3 (ex-QUIC) for CentOS 8 / RHEL 8/ AlmaLinux 8 / Rocky Linux 8. To get it, you need to install and configure our test repo:
yum install -y https://repo.codeit.guru/codeit-repo-release.el8.rpm epel-release && dnf module enable -y nginx:codeit-quic
The package has version 1.26.1-1, but defined nginx binary version is 1.27.1. This is a known issue. See bundled /etc/nginx/conf.d/default-ssl.conf.example for working HTTP/3 configuration example on port 443/UDP!
For testing purposes only!
