How To Install Redis On Windows | Steps To Install Redis On Windows
Redis on windows server: no config file specified
Try to start with the below command
redis-server --port 6380 --slaveof 127.0.0.1 6379How To Implement Caching in Node.js Using Redis

To run Redis from your local machine instead of the remote server, follow these steps:
1. Install Redis Locally
If you haven’t installed Redis on your local machine yet, you can follow these steps:
Using Windows:
Download and install Redis for Windows from the official repository: Download Redis for Windows.
After installation, start the Redis server by running redis-server.exe.
2. Update the .env File
To run Redis locally, update your .env file with the following:
REDIS_URL=redis://127.0.0.1:6379
127.0.0.1 is the localhost IP address.
6379 is the default port on which Redis runs.
3. Run redis-cli Locally
To connect to your local Redis instance using redis-cli, use the following command:
redis-cli
This will connect to 127.0.0.1 on port 6379 by default.
If you want to specify the IP and port explicitly, you can use:
redis-cli -h 127.0.0.1 -p 6379
4. Test the Connection
After setting up your local Redis instance and updating the .env file, you can test the connection using the PING command:
redis-cli PING
You should get a response of PONG if the server is running correctly.
5. Start Your Node.js Application
With the .env file updated to use redis://127.0.0.1:6379, you can now start your Node.js application as usual. It will connect to the local Redis instance.
Summary
Redis URL in .env: REDIS_URL=redis://127.0.0.1:6379
Command to Connect Locally: redis-cli
These steps will allow you to run and connect to a Redis instance locally on your Windows machine.
———–
To install Redis on your local machine and configure it for use in a Node.js project, follow these steps:
1. Installing Redis
Download the latest Redis release from the Microsoft Open Tech Redis GitHub repository.
Extract the downloaded .zip file to a folder.
Open the extracted folder, find redis-server.exe, and run it to start the Redis server.
Verify that Redis is running:
Open a new Command Prompt window and run:
redis-cli ping
If Redis is running, it will return PONG.
2. Configuring the .env File
In your Node.js project’s .env file, you need to set the REDIS_HOST and REDIS_PORT environment variables.
REDIS_HOST: The IP address of the Redis server. For a local setup, this is typically 127.0.0.1 (localhost).
REDIS_PORT: The port Redis is running on. The default Redis port is 6379.
Here is an example .env configuration:
REDIS_HOST=127.0.0.1 REDIS_PORT=6379
3. Connecting to Redis in Your Node.js Project
Install the redis package using npm:
npm install redis
Then, connect to Redis in your Node.js code like this:
const redis = require('redis');
const client = redis.createClient({
host: process.env.REDIS_HOST,
port: process.env.REDIS_PORT,
});
client.on('connect', function() {
console.log('Connected to Redis');
});
client.on('error', function(err) {
console.error('Redis error:', err);
});
This setup will allow your Node.js application to connect to the locally running Redis server.
how to check redis version installed in windows ?
o check the Redis version installed on Windows, follow these steps:
a. Navigate to the Redis Folder (if needed):
If Redis is not added to your system’s PATH, navigate to the directory where redis-cli.exe is located. For example:
cd C:\path\to\redis\folder
b. Run the redis-cli Command:
Use the following command to check the Redis server version:
redis-cli --version
c.Alternatively, you can connect to the Redis server and check the version with:
redis-cli
d.Once connected, type the following command:
INFO server
C:\Users\Administrator>redis-cli 127.0.0.1:6379> INFO server # Server redis_version:3.0.504 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:a4f7a6e86f2d60b3 redis_mode:standalone os:Windows arch_bits:64
e.Look for the redis_version field in the output. It will show the version of the Redis server.
redis_version:6.0.9
To test if a remote Redis server (specified by an IP address) is running and accessible from your local Windows PC, you can use the following methods:
1. Using redis-cli Command
If you have Redis installed on your Windows machine, you can use the redis-cli tool to connect to the remote Redis server:
a.Run the redis-cli Command:
Use the following command to connect to the remote Redis server using the IP and port (default is 6379):
redis-cli -h-p
Replace
Example:
redis-cli -h 192.168.1.100 -p 6379
b.Test the Connection:
If the connection is successful, you’ll see a prompt like this:
192.168.1.100:6379>
You can then type the PING command to test if the server is responding:
PING
If the server is running, it will return PONG.
Error : Could not connect to Redis at 35.xyz.abc.128:xv379: Unknown error
not connected –
1. Verify Network Connectivity
Ensure that your local machine can reach the Redis server:
Ping the IP Address:
ping 35.xyz.abc.128
2. Check Redis Server
Ensure that the Redis server is running and listening on the correct IP address and port:
Server Status: If you have access to the server, check if Redis is running:
redis-server --version
3.Verify Redis Authentication
If your Redis server requires a password and you didn’t provide it, the connection will fail. Use the -a option with redis-cli to provide the password:
redis-cli -h 35.xyz.abc.128 -p xv379 -a yourpassword
Replace yourpassword with the actual Redis password.

After Install Redis , while run the redis server command, we are getting this error :
Error :
Creating Server TCP listening socket *:6379: bind: No such file or directory redis error windows
Solution :
You must’ve used the .msi installer. It automagically registers a windows service which starts instantly after the installation (at least on my win 10 machine).
This service uses the default config and binds to port 6379. When you start redis-server from the command line, if you haven’t specified a different port through a config file, it picks up the default config again and tries to bind to port 6379 which fails.
Your cli works because it connects to the redis service that’s already listening on 6379. Your shutdown command stops the service and from there things work as expected. Mystery solved. Case closed.
As per the above reason , we have fixed by following these steps
Step 1 : Identify the PIDs Using Port 6379
“netstat -ano | findstr :6379”
Step 2 : After get the result , The last column shows the PIDs (1234 and 5678 in this example).
Step 3 : Terminate the Processes
Use the taskkill command to terminate each process by its PID.
“taskkill /PID 1234 /F”
This should terminate the processes running on port 6379, allowing Redis to bind to that port successfully.
Step 4 : Now check the redis server command , If you are using the Command Prompt, navigate to the directory where Redis is installed and run:
“redis-server” (or) “redis-server redis.windows.conf”
Redis 3.0.504 (00000000/0) 64 bit
Running in standalone mode
Port: 6379
PID: 15296
Or if you are using a different configuration file, specify it accordingly:
“redis-server path\to\your\redis.conf”
Redis Port : 6379
redis-cli info
If we want run and use cli command , apply this command :
redis-server –service-start
redis-cli
set channelName “codespace”
get channelName
(or)
redis-cli get channelName
Stop redis : “redis-cli shutdown”
Database Selection:
Redis can have multiple logical databases. Ensure that the correct database is being used both when adding data and when querying data.
redis-cli
SELECT
KEYS * (or) HGETALL
redis-cli
SET testkey “testvalue”
GET testkey
Run the Redis server executable directly from the command line
Use the command line to stop Redis by sending the SHUTDOWN command via
redis-cli SHUTDOWN
include cleanup commands in your scripts to ensure no lingering processes
taskkill /F /IM redis-server.exe
C:\Program Files\Redis>redis-cli
127.0.0.1:6379> select 4
OK
127.0.0.1:6379[4]> keys *
To shutdown the redis , we need to come out from select by ctrl+c
