Open Redis port for remote connections

Question

I can ping pong Redis on the server:

# redis-cli ping
PONG

But remotely, I got problems:

$ src/redis-cli -h REMOTE.IP ping
         


        

Answer 1

Did you set the bind option to allow remote access on the redis server?

Before (file /etc/redis/redis.conf)

bind 127.0.0.1

After

bind 0.0.0.0

and run sudo service redis-server restart to restart the server. If that's not the problem, you might want to check any firewalls that might block the access.

Important: If you don't use a firewall (iptables, ufw..) to control who connects to the port in use, ANYONE can connect to this Redis instance. Without using Redis' AUTH that means anyone can access/change/delete your data. Be safe!
