Error: connect ECONNREFUSED 127.0.0.1:6379 - redis

Question

I have coding like this
const redis = require("redis");
const client = redis.createClient();
client.on("connect", function() {
console.log("You are now connected");
});
client.set("student", "Laylaa", function(err, reply) {
console.log(reply);
});
but there is an error like this..
events.js:291
throw er; // Unhandled 'error' event
^
Error: connect ECONNREFUSED 127.0.0.1:6379

}
is there a solution? Thanks

Answer 1

You need to first start the redis server by executing:
redis-server
in a terminal, after redis has been installed and before launching the Node.js client.
You could also add a script to your package.json:
"scripts": {
"redis": "redis-server"
}
and run:
npm run redis

Answer 2

On Linux Ubuntu you’ll need to run
sudo apt-get install redis-server
and Redis will automatically be up and running.Once it’s started, Redis listens on port 6379
.
