Could not connect to Redis at 127.0.0.1:6379: Connection refused

 

redis-server 명령어로 redis 실행시켜준 후 

root@DESKTOP-Q26RDFJ:~# redis-server
617:C 12 Sep 2023 13:37:43.911 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

접속을 재시도하니 잘 됩니다.
