I solve this problem in next way:

that error fixed but now new error show i.e, "Error: ERR wrong number of arguments for 'set' command" – Mctyre

Thanks! this resolved the issue, just a small note on Linux/WSL environments after installing re-run the command redis-server or prefix it by sudo if needed. If all goes well, you will see redis-server cli message. also can be verified by sudo service redis-server status as suggested by @author. – Ogham

Answer 5

For those of you who are using docker with docker-compose and Typescript my solution was

import { RedisClient } from 'redis';

 const pubClient = new RedisClient({ url: 'redis://redis:6379' });

to

import { createClient } from 'redis';

const pubClient = createClient({ url: 'redis://redis:6379' });

docker-compose.yml

version: '3.9'

services:
  main:
    build:
      context: .
      target: development
    ports:
      - ${PORT}:${PORT}
    volumes:
      - ./src:/usr/src/app/src
      - /app/node_modules
    env_file:
      - .env
    command: npm run start:dev
    depends_on:
      - mongo
      - redis
  mongo:
    image: mongo:5.0.2-focal
    volumes:
      - mongo-data:/data/db
  mongo-express:
    image: mongo-express:0.54.0
    ports:
      - 8081:8081
    depends_on:
      - mongo
  redis:
    image: redis:6.2.5-alpine

Answer 9

I also have the same problem, first I tried to restart redis-server by sudo service restart but the problem still remained. Then I removed redis-server by sudo apt-get purge redis-server and install it again by sudo apt-get install redis-server and then the redis was working again. It also worth to have a look at redis log which located in here /var/log/redis/redis-server.log

Answer 11

For me I had this issue on Ubuntu 18.x, but my problem was that my redis-server was running on 127.0.0.1 but I found out I needed to run it on my IP address xxx.xx.xx.xx

I went into my Ubuntu machine and did the following.

cd /etc/redis/

sudo vim redis.conf

Then I edited this part.

################################## NETWORK #####################################

# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 loopback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).le to listen to just one or multiple selected interfaces using
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# bind 127.0.0.1 ::1 10.0.0.1
bind 127.0.0.1 ::1 # <<-------- change this to what your iP address is something like (bind 192.168.2.2)

Save that, and then restart redis-server.

sudo service redis-server restart or simply run redis-server

Answer 12

For windows platform, You must check if redis-server is running on given ip:port. you can find redis configuration at installation directory /conf/redis.conf. by default client accept 127.0.0.1:6379.

Answer 14

I think maybe you installed redis by source code.If that you need locate to redis-source-code-path/utils and run sudo install_server.sh command. After that, make sure redis-server has been running as a service for your system sudo service redis-server status

PS: based on Debian/Ubuntu

Answer 15

In case of ubuntu, the error is due to redis-server not being set up. Install the redis-server again and then check for the status.

If there is no error, then a message like this would be displayed :-

● redis-server.service - Advanced key-value store Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2018-01-17 20:07:27 IST; 16s ago Docs: http://redis.io/documentation, man:redis-server(1) Main PID: 4327 (redis-server) CGroup: /system.slice/redis-server.service └─4327 /usr/bin/redis-server 127.0.0.1:6379
