Posso pingare Redis sul server:
# redis-cli ping
PONG
Ma a distanza, ho problemi:
$ src/redis-cli -h REMOTE.IP ping
Could not connect to Redis at REMOTE.IP:6379: Connection refused
In config, ho ottenuto la porta standard:
# Accept connections on the specified port, default is 6379.
# If port 0 is specified Redis will not listen on a TCP socket.
port 6379
Quindi forse dovrei aprire la porta 6379 sulla macchina Ubuntu remota? Come lo faccio?
