You can find tutorial here.

Install Dragonfly

export VERSION="1.25.4"

wget https://github.com/dragonflydb/dragonfly/releases/download/v${VERSION}/dragonfly_amd64.deb
sudo dpkg -i dragonfly_amd64.deb

sudo tee /etc/dragonfly/dragonfly.conf <<EOF

--cache_mode=true
--df_snapshot_format=false
EOF

sudo chown dfly:dfly /etc/dragonfly/dragonfly.conf

sudo systemctl enable dragonfly
sudo systemctl restart dragonfly
sudo systemctl status dragonfly

Install Redis

sudo apt -y install build-essential pkg-config

export REDIS_VER="7.4.1"

wget https://github.com/redis/redis/archive/refs/tags/${REDIS_VER}.tar.gz
tar -xzf ${REDIS_VER}.tar.gz
sudo mv redis-${REDIS_VER}/ /opt/redis
cd /opt/redis/
make
sudo make install
