Description

Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

You can run atomic operations on these types, like appending to a string; incrementing the value in a hash; pushing to a list; computing set intersection, union and difference; or getting the member with highest ranking in a sorted set.

In order to achieve its outstanding performance, Redis works with an in-memory dataset. Depending on your use case, you can persist it either by dumping the dataset to disk every once in a while, or by appending each command to a log.

Redis also supports trivial-to-setup master-slave replication, with very fast non-blocking first synchronization, auto-reconnection on net split and so forth.

Setup Redis

• Install as normal package

  sudo pkg install redis
  

• Amend configuration /usr/local/etc/redis.conf:

  • Disable TCP listening by setting: port 0

  • Enable listening on sockets:

    unixsocket /var/run/redis/redis.sock
    # Grant permission to the socket to all members of the redis group
    unixsocketperm 770
    

• Enable service on startup: sudo sysrc redis_enable=yes

• Start service: sudo service redis restart
