MongoDB: How to Find the Exact Version of Installed MongoDB 🚀

So, you have MongoDB installed on your Windows 7 machine and you want to find out its specific version. You open the MongoDB database shell (mongo.exe) and see that it outputs the shell version as "MongoDB shell version: 3.2.0". But wait, is this the same as your actual database version? 🤔

Don't worry, I've got you covered! In this blog post, I'll show you a simple and foolproof way to find the exact version of your installed MongoDB. Let's dive right in! 💪

The Problem: Differentiating Shell Version from Database Version 🐢

The confusion arises because the MongoDB database shell version is not necessarily the same as the version of your actual MongoDB database. 😫 This can make it tricky to determine the exact version of your installation. But fear not, there's a solution!

Solution 1: Using the db.version() Command 📝

The db.version() command provides you with the version of your connected MongoDB server. Follow these simple steps to find your MongoDB version:

1. Open your MongoDB database shell (mongo.exe) by clicking on it or running it from your command line interface.

2. Connect to your MongoDB server by typing mongo in the shell and hitting Enter.

3. Once connected, type db.version() in the shell and hit Enter.

Voilà! 🎉 You will see your MongoDB server version displayed in the shell output. This command fetches the version information directly from the connected server, ensuring accurate data.

Solution 2: Checking the Contents of the dbpath Directory 📂

If Solution 1 doesn't work for any reason, don't worry, there's another way to find your MongoDB version. Simply follow these steps to check the contents of the dbpath directory:

1. Open the Windows File Explorer and navigate to the directory where your MongoDB data files are stored. By default, this is the /data/db folder.

2. Locate the file named WiredTiger.wt.

3. Right-click on the file and select "Properties".

4. In the "Details" tab, you will find the "Product version" field. This field contains your MongoDB version.

And there you have it! 🙌 You now know how to find the exact version of your installed MongoDB, whether it's through the db.version() command or by checking the details of the WiredTiger.wt file.
