How to know Redis is installed or not in WSL

How to Check if Redis is Installed on WSL (and How to Fix It)

If you're developing on Windows, using Redis inside Windows Subsystem for Linux (WSL) is the gold standard for performance. But sometimes, it’s hard to tell if you already have it set up or if the service is just sleeping.

Here is a quick guide to verifying your Redis installation and getting it running in seconds.

Phase 1: The "Quick Check"

Before digging into system logs, try these two commands to see if Redis is already in your path.

1. Check the Version

redis-server --version

  • Success: You’ll see Redis server v=7.x.x.

  • Failure: You’ll see command not found.

2. Locate the Binary

which redis-server

This tells you exactly where the executable lives (usually /usr/bin/redis-server). If it returns nothing, Redis likely isn't installed.

Phase 2: Verifying via Package Manager

If the commands above failed, it’s possible the package is there but not in your environment path. Check the dpkg database:

dpkg -l | grep redis

Look for the ii prefix, which indicates the package is "Installed/Installed."

Phase 3: Is the Service Actually Running?

Just because it's installed doesn't mean it's "alive." Use the Redis CLI to send a "heartbeat" to the server.

redis-cli ping

  • Expected Response: PONG

  • Error Response: Could not connect to Redis at 127.0.0.1:6379: Connection refused

If you get an error, check the service status:


sudo service redis-server status
# OR (if using systemd)
sudo systemctl status redis-server

Phase 4: How to Install (If you're starting fresh)

If you realized you don't have it yet, don't sweat it. Run these commands in your WSL terminal:

  1. Update your packages:


    sudo apt update

  2. Install the server:


    sudo apt install redis-server

  3. Start the service:


    sudo service redis-server start

Pro Tip: To make sure Redis starts every time you boot up your WSL instance, run: sudo systemctl enable redis-server

Final Verification

Run redis-cli ping one last time. If you see that glorious PONG, you’re ready to start caching!

Finding Your Redis Credentials: Host, Port, and Password

 Finding Your Redis Credentials: Host, Port, and Password Here is how to hunt down your Redis credentials in seconds. 1. The Host: Where is Redis living? In 90% of local development scenarios (including WSL), Redis lives right on your machine. Standard Local Host: 127.0.0.1 or localhost Remote Server: If you're connecting to a staging or production server, you will need that server's specific IP address or domain name (e.g., redis.example.com ). 2. The Port: Which door is open? The default port for Redis is 6379 . However, if you're running multiple instances, it might be different. To confirm exactly which port your instance is listening on, run: redis-cli CONFIG GET port Alternatively, you can ask your system which process is "squatting" on the network: sudo ss -tlnp | grep redis If you see 0.0.0.0:6379 , you're using the default. 3. The Password: Is the gate locked? By default, a fresh Redis installation has no password . In a local environment, this is ...

Ways to install your own extension

 In visual studio  Extension Manager ,  shows extensions from the Marketplace. But you can install your own .vsix extension manually — here’s how: 🛠️ Ways to install your own extension Double‑click the VSIX file : After you build your extension project, Visual Studio produces a .vsix file. Just double‑click it, and the Visual Studio Installer will open to install it. Use the Experimental Instance : When debugging your extension, Visual Studio launches a special “Experimental Instance” where your extension is auto‑installed for testing. Command line install : You can use VSIXInstaller.exe (included with Visual Studio) to install your extension manually. Example:                          VSIXInstaller.exe MyExtension.vsix Local install via Extensions menu : In newer Visual Studio versions, go to Extensions → Manage Extensions → Install from VSIX… and select your file.
