redis

brew install redis

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

可以编辑 /usr/local/etc/redis.conf， 设置 redis 密码 requirepass

启动：

# redis-server
redis-server /usr/local/etc/redis.conf

127.0.0.1:6379> pfadd mykey a b c
(integer) 1
127.0.0.1:6379> pfcount mykey
