The installation is successful.

Default 27017 Port

Enter localhost: 27017 in the browser.

We can see that this statement proves that mongodb is successfully installed. 3. Set window environment variables

The path of the execution file in the extracted binfile is directly placed in the environment variable, so that we can directly access all the programs through cmd.

4. bat file

Start mongodb Service
