Redis version: 3.2.0 Jedis version: 2.8.1
Below is my java code for connecting to redis:
public class TestRedis {
public static void main(String[] args) {
String host = args[0];
int port = Integer.parseInt(args[1]);
try (Jedis jedis = new Jedis(host, port)) {
System.out.println("Connected to jedis " + jedis.ping());
} catch(Exception e){
e.printStackTrace();
}
}
}
I am running this program in the machine where redis is installed. This machine's ip address is 192.168.1.57
If I provide host="localhost" and port = "6379" as arguments, connection with redis successfully established.
However, If I give host="192.168.1.57" and port = "6379" in arguments, I end up with below exception:

There are a few settings that would affect this: bind and protected-mode. They work together to provide a baseline of security with new installs.
Find the following in your redis.conf
file and comment it out:
bind 127.0.0.1
By adding a #
in front of it:
# bind 127.0.0.1
Or, if you would rather not comment it out, you can also add the IP of your eth0
/em1
interface to it, like this:
bind 127.0.0.1 192.168.1.57
Also, unless you're using password security, you'll also have to turn off protected mode by changing:
protected-mode yes
To:
protected-mode no
Make sure that you read the relevant documentation and understand the security implications of both of these changes.
After making these changes, restart redis.
