Install Redis on Debian

Redis is a key-value database. This guide installs it on Debian 12.

Setup Repositories

Add the Redis repository to APT:

sudo apt-get install lsb-release curl gpg
curl -fsSL https://packages.redis.io/gpg | sudo gpg --dearmor -o /usr/share/keyrings/redis-archive-keyring.gpg
sudo chmod 644 /usr/share/keyrings/redis-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/redis-archive-keyring.gpg] https://packages.redis.io/deb $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/redis.list

Note for LXC: If lsb_release fails, enable nesting or specify the distro name manually. For Debian 12, use bookworm.

Install Redis

sudo apt update
sudo apt install redis

The default configuration file is at:

sudo nano /etc/redis/redis.conf

Test that Redis is running:

redis-cli ping

A successful response returns PONG.
