==> Caveats
To have launchd start redis now and restart at login:
  brew services start redis
Or, if you don't want/need a background service you can just run:
  redis-server /usr/local/etc/redis.conf
==> Summary
🍺  /usr/local/Cellar/redis/4.0.9: 13 files, 2.8MB

Redisに接続する

redis-cliコマンドで接続する

$ redis-cli

データの登録と取得と削除

ちなみに、上のURLでredis-cliが直接試せる！

$ redis-cli
127.0.0.1:6379> set Key Value
OK
127.0.0.1:6379> get Key
"Value"
127.0.0.1:6379> del Key
(integer) 1
127.0.0.1:6379> get Key
(nil)
127.0.0.1:6379> Keys *
(empty list or set)

クエリを監視する

redis-cli
127.0.0.1:6379> monitor
OK
1528253210.741621 [0 127.0.0.1:50277] "COMMAND"
1528253218.106875 [0 127.0.0.1:50277] "Keys" "*"
.
.
.

クエリの監視結果をファイルに保存する

redis-cli -h `host` -p `port` -a `auth` monitor > monitor.log

redis-cliを終了する

127.0.0.1:6379> quit
