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

Another possibly helpful note.

Redis can be bound to multiple IPs - that's very helpful when you don't want to open it to entire world (0.0.0.0) but only make it accessible in local networks.

1. sudo nano /etc/redis/redis.conf
2. add your local network IP to the end of bind setting:

bind 127.0.0.1 10.0.0.1

3. restart the service: sudo service redis-server restart

Now you can easily access redis from other computers in same network, e.g. redis-cli -h 10.0.0.1

A quick note that doing this without further securing your Redis server is not a good idea as it can leave you open to attack. Be sure to also implement AUTH or otherwise secure that. See http://redis.io/topics/security for details.

Answer 3

A quick note that if you are using AWS ec2 instance then there is one more extra step that I believe is also mandatory. I missed the step-3 and it took me whole day to figure out to add an inbound rule to security group

Step 1(as previous): in your redis.conf change bind 127.0.0.1 to bind 0.0.0.0

Step2(as previous): in your redis.conf change protected-mode yes to protected-mode no

important for Amazon Ec2 Instance:

Step3: In your current ec2 machine go to the security group. add an inbound rule for custom TCP with 6379 port and select option "use from anywhere".

Answer 4

1. Open the file at location /etc/redis.conf

2. Comment out bind 127.0.0.1

3. Restart Redis:

    sudo systemctl start redis.service
   

4. Disable Firewalld:

    systemctl disable firewalld
   

5. Stop Firewalld:

    systemctl stop firewalld
   

Then try:

redis-cli -h 192.168.0.2(ip) -a redis(username)

Answer 5

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

Answer 6

In my case, I'm using redis-stable

Go to redis-stable path 
 cd /home/ubuntu/software/redis-stable

Open the redis.conf

vim redis.conf

Change the bind 127.0.0.1 to bind 0.0.0.0

change the protected-mode yes to protected-mode no

Restart the redis-server:

/etc/init.d/redis-server stop
 redis-server redis.conf
