[8] Redis – Python

To jest przykład użycia Redis w Pythonie 3.

[1] Zainstaluj bibliotekę Python 3 Redis na komputerze kliencie.

#zainstaluj z EPEL
[root@vlsr01 ~]# dnf --enablerepo=epel install python3-redis

[2] Podstawowe użycie Pythona.

[user01@vlsr01 ~]$ mcedit use_redis.py
#utworz nowy
import redis
client = redis.StrictRedis(host='127.0.0.1', port=6379, db=0, password='TajneHasło')
#ustaw i pobierz klucz
client.set('key01', 'value01')
print('key01.value :', client.get('key01'))
#dodaj i pobierz klucz
client.append('key01', ',value02')
print('key01.value :', client.get('key01'))
client.set('key02', 1)
#inkrementuj
client.incr('key02', 100)
print('key02.value :', client.get('key02'))
#dekrementuj
client.decr("key02", 51)
print('key02.value :', client.get('key02'))
#listuj
client.lpush('list01', 'value01', 'value02', 'value03')
print('list01.value :', client.lrange('list01', '0', '2'))
#mieszaj
client.hmset('hash01', {'key01': 'value01', 'key02': 'value02', 'key03': 'value03'})
print('hash01.value :', client.hmget('hash01', ['key01', 'key02', 'key03']))
#ustaw
client.sadd('set01', 'member01', 'member02', 'member03')
print('set01.value :', client.smembers('set01'))

#uruchom
