Configure Redis Servers

Oro architecture requires a least two instances of Redis server. The first instance will be used as fast persistent storage for sessions and the second one as LRU Cache storage.

Ubuntu Xenial or later

Install redis-server via apt

sudo apt install redis-server

Configure Second Instance as LRU Memory Cache

Create folders for the redis-cache server

sudo mkdir -p /var/lib/redis-cache /var/log/redis-cache /var/run/redis-cache
sudo chown redis:redis /var/lib/redis-cache /var/log/redis-cache /var/run/redis-cache

Create tmpfiles config

echo "d /run/redis-cache 2775 redis redis -" | sudo tee /usr/lib/tmpfiles.d/redis-cache-server.conf

Copy original configs for the second server

sudo cp -rp /etc/redis /etc/redis-cache

Replace all content in /etc/redis-cache/redis.conf with:

Enable and start systemd unit

systemctl enable redis-cache-server.service
systemctl start redis-cache

Verify the status of the new service

systemctl status redis-cache
