Ubuntu System Setup Guide

This guide will help you set up a basic development environment on Ubuntu with the following tools:

Update and upgrade the system
Install nvm (Node Version Manager)
Install Node.js 20
Install Git
Install NGINX
Install mysql-server
Install phpmyadmin
Install php latest version with php-fpm

Prerequisites

Ubuntu (any version)
A terminal or SSH access to the system

1. Update and Upgrade the System

Start by updating and upgrading your Ubuntu packages to make sure you have the latest versions and security patches.

sudo apt update && sudo apt upgrade -y

This will: Update the local package index (apt update) Upgrade all the installed packages to the latest version (apt upgrade)

2. Install NVM (Node Version Manager)

Next, we'll install nvm (Node Version Manager) to manage multiple versions of Node.js.

Install NVM

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

Once the installation is complete, you’ll need to restart your terminal or source your profile:

source ~/.bashrc   # Or use ~/.zshrc or ~/.profile based on your shell

Verify the Installation You can verify that nvm is installed successfully by running:

command -v nvm

If the installation was successful, it should return nvm.

3. Install Node.js Version 20

Now that nvm is installed, you can use it to install Node.js version 20:

nvm install 20

Set Node.js 20 as Default Version

To set Node.js version 20 as the default version for your terminal sessions, run:

nvm use 20
nvm alias default 20

You can verify the installed version of Node.js by running:

node -v

4. Install Git

Git is essential for version control. To install Git, run the following:

sudo apt install git -y

Verify the Installation

To check if Git is installed correctly, run:

git --version

Install NGINX Finally, install NGINX, a popular web server.

Install NGINX

sudo apt install nginx -y
sudo systemctl start nginx
sudo systemctl enable nginx

5.Install MySQL Server

sudo apt install mysql-server -y

Secure the MySQL installation:

sudo mysql_secure_installation

Follow the prompts to set a root password and secure the database.

6. Install PHP 8.3 or Latest Version

Add the repository and install PHP:

sudo add-apt-repository ppa:ondrej/php -y
sudo apt update
sudo apt install php8.3 php8.3-fpm php8.3-cli php8.3-mysql php8.3-curl php8.3-xml php8.3-mbstring php8.3-zip php8.3-bcmath php8.3-gd php8.3-intl php8.3-readline -y

Restart PHP-FPM:

sudo systemctl restart php8.3-fpm

7. Install phpMyAdmin

sudo apt install phpmyadmin -y

During the installation, select NGINX and configure the database for phpMyAdmin.

Create a symbolic link for phpMyAdmin in the NGINX web directory:

sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

Restart NGINX:

sudo systemctl restart nginx

8. Create a User for phpMyAdmin and Grant Privileges

sudo mysql -u root -p

Create a new user:

CREATE USER 'phpmyadmin_user'@'localhost' IDENTIFIED BY 'secure_password';

Grant privileges:

GRANT ALL PRIVILEGES ON *.* TO 'phpmyadmin_user'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
EXIT;

9. Configure Firewall (UFW)

Allow necessary ports:

sudo ufw allow 22/tcp  # SSH
sudo ufw allow 80/tcp  # HTTP
sudo ufw allow 443/tcp # HTTPS
sudo ufw enable

10. Install and Configure Code Server

Step 1: Install Code Server

curl -fsSL https://code-server.dev/install.sh | sh

Step 2: Configure Code Server for the Current User

mkdir -p ~/.config/code-server
nano ~/.config/code-server/config.yaml

Add the following configuration:

bind-addr: 127.0.0.1:8080
auth: password
password: "your_secure_password"
cert: false

Save and exit (CTRL+X, Y, ENTER).

Start Code Server:

code-server

To run it as a service:

sudo systemctl enable --now code-server@$USER

11. Install Certbot and Secure Domain with Let's Encrypt
