Open Redis port for remote connections

Bind & protected-mode both are the essential steps. But if ufw is enabled then you will have to make redis port allow in ufw.

1. Check ufw status ufw status if Status: active then allow redis-port ufw allow 6379
2. vi /etc/redis/redis.conf
3. Change the bind 127.0.0.1 to bind 0.0.0.0
4. change the protected-mode yes to protected-mode no

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!

For me, I needed to do the following:

1- Comment out bind 127.0.0.1

2- Change protected-mode to no

3- Protect my server with iptables (https://www.digitalocean.com/community/tutorials/how-to-implement-a-basic-firewall-template-with-iptables-on-ubuntu-14-04)
