Installing and configuring a MEAN (MongoDB, Express.js, Angular.js, Node.js) stack on a VPS (Virtual Private Server) requires multiple steps. Here is a general guide that will help you accomplish this:
Step 1: Update your system
Start by updating your VPS to ensure you have the latest versions of necessary software. You can do this using the following commands:
```
sudo apt-get update
sudo apt-get upgrade
```
Step 2: Install Node.js
Node.js is a JavaScript runtime that allows you to run JavaScript on your server. You can install Node.js via package manager:
```
sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
```
You can verify the installation by typing:
```
node —version
npm —version
```
Step 3: Install MongoDB
MongoDB is a document database that makes it easier to work with data. Install MongoDB using the commands:
```
sudo apt-get install mongodb
```
To verify if MongoDB has been installed and the service is running correctly:
```
sudo systemctl status mongodb
```
Step 4: Install Express.js
Express is a web application framework for Node.js that simplifies its features. Install Express generator through npm, which is included in your Node.js installation:
```
sudo npm install -g express-generator
```
Step 5: Install Angular
Angular is a framework for building client-side applications. Angular CLI is a command-line interface to scaffold and build Angular apps. Install it with:
```
sudo npm install -g @angular/cli
```
You can check the installed version with:
```
ng version
```
Now you have installed all the components of MEAN Stack.
Step 6: Configure Your MEAN application
Express.js setup
Run the following command to create a new express application
```
express myApp
```
Navigate into your new project directory
```
cd myApp
```
Install the project dependencies
```
npm install
```
Start your Express.js app
```
npm start
```
Angular.js setup
Navigate to the folder where you want your project to be, and run the following command to create a new Angular application:
```
ng new myApp
```
Navigate into your new project directory:
```
cd myApp
```
Start your application:
```
ng serve
```
Be sure to replace “myApp” with the name of your project.
This is a simplified version of the procedure and is meant for a debian-like linux distribution. For a more detailed process and for other versions of Linux, the appropriate documentation should be checked.
Also, it is advisable to install MongoDB from the official MongoDB repositories, as the one included in the Ubuntu repositories might be outdated. Please refer to the MongoDB official documentation for information on how to add their repository.
