Connection to redis is timing out [closed]

Question

$ redis-cli -h ec2-75-101-204-XXX.compute-1.amazonaws.com
Could not connect to Redis at ec2-75-101-204-XXX.compute-1.amazonaws.com:6379: Operation timed out

That's what I get from my host machine. I set up the Security Group on that machine to be open to port 6379.

When I run netstat on the redis server, I see that it's listening:

$ netstat -nlp
(No info could be read for "-p": geteuid()=1000 but you should be root.)

Active UNIX domain sockets (only servers)

My redis.conf looks like:

daemonize yes
pidfile /var/run/redis.pid
port 6379
timeout 300
loglevel notice
logfile /var/log/redis.log
databases 16

save 900 1
save 300 10
save 60 10000

stop-writes-on-bgsave-error yes
rdbcompression yes

So why would I be timing out from another machine?

Answer 1

redis is only listening on the localhost port: 127.0.0.1:6379.

You need to configure redis to bind on 0.0.0.0.

in redis.conf (most likely at /etc/redis/redis.conf, replace (or add if not present)

bind 127.0.0.1

with

bind 0.0.0.0
