Configuring Redis

For persistent queue, like for Sidekiq

sudo nano /etc/redis/6379.conf 
  # use Ctrl+W to search in nano  
  
  supervised systemd
  maxclients 1000
  databases 1
  # maxmemory <bytes>
  maxmemory-policy noeviction

For a LRU-expiring cache

sudo nano /etc/redis/6380.conf 
  # use Ctrl+W to search in nano  
  
  supervised systemd
  maxclients 1000
  databases 1
  maxmemory 500mb
  maxmemory-policy noeviction
