How to Install and Set Up Apache or Nginx on a Linux VPS Like a Pro ~ 99RDP

When it comes to hosting a website or web application on a Linux VPS, choosing the right web server is crucial. Apache and Nginx are the two most widely used web servers, each offering unique benefits for different use cases. Apache is known for its flexibility and compatibility, while Nginx is celebrated for its high performance and ability to handle large traffic loads efficiently.

In this guide, we’ll walk you through the step-by-step process of installing and configuring Apache or Nginx on a Linux VPS. Whether you’re setting up a personal blog, an e-commerce store, or a corporate website, this tutorial will help you get your web server up and running smoothly.

1. Prerequisites

Before we dive into the installation process, make sure you have the following:

✅ A Linux VPS – You can get an affordable and high-performance VPS from 99RDP.
✅ SSH access – You need to connect to your VPS using SSH (via PuTTY or Terminal).
✅ A user with sudo privileges – Root access is required for installation.
✅ A registered domain name (optional but recommended for website hosting).

2. Choosing Between Apache and Nginx

Before installing a web server, it's important to understand the key differences between Apache and Nginx:

Feature	Apache	Nginx
Performance	Good for small to medium sites	Excellent for high-traffic sites
Concurrency	Thread-based handling	Event-driven, handles multiple requests efficiently
Configuration	Supports .htaccess	Uses server blocks
Reverse Proxy	Possible, but not optimal	Designed for reverse proxying
Flexibility	Highly customizable	Optimized for speed and scalability

Which One Should You Choose?

Choose Apache if you need .htaccess support, ease of use, and compatibility with many applications.
Choose Nginx if you need better performance, scalability, and efficient resource management.

Now, let’s proceed with installing your preferred web server.

3. Installing Apache on a Linux VPS

For Ubuntu/Debian

Step 1: Update System Packages

Before installing Apache, update your system to ensure you have the latest packages:

sudo apt update && sudo apt upgrade -y

Step 2: Install Apache

Install Apache using the following command:

sudo apt install apache2 -y

Step 3: Start and Enable Apache

Once installed, start the Apache service and enable it to launch on boot:

sudo systemctl start apache2
sudo systemctl enable apache2

Step 4: Verify Installation

Check if Apache is running with:

systemctl status apache2

Step 5: Allow Apache Through the Firewall

If you have UFW (Uncomplicated Firewall) enabled, allow Apache traffic:

sudo ufw allow 'Apache Full'

Step 6: Test Apache Installation

Open your browser and enter your VPS IP address (http://your-vps-ip). If Apache is running correctly, you’ll see the default Apache welcome page.

For CentOS/RHEL

Step 1: Install Apache

sudo yum install httpd -y

Step 2: Start and Enable Apache

sudo systemctl start httpd
sudo systemctl enable httpd

Step 3: Allow Apache Through the Firewall

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Step 4: Verify Installation

systemctl status httpd

Apache is now installed and running on your Linux VPS! 🚀

4. Installing Nginx on a Linux VPS

For Ubuntu/Debian

Step 1: Update System Packages

Before installing Nginx, update your system to get the latest package lists:

sudo apt update && sudo apt upgrade -y

Step 2: Install Nginx

Run the following command to install Nginx:

sudo apt install nginx -y

Step 3: Start and Enable Nginx

After the installation is complete, start Nginx and enable it to launch on boot:

sudo systemctl start nginx
sudo systemctl enable nginx

Step 4: Verify Installation

Check if Nginx is running with:

systemctl status nginx

Step 5: Allow Nginx Through the Firewall

If you are using UFW, allow HTTP and HTTPS traffic:

sudo ufw allow 'Nginx Full'

Step 6: Test Nginx Installation

Open your web browser and enter your VPS IP address (http://your-vps-ip). If Nginx is running correctly, you’ll see the default Nginx welcome page.

For CentOS/RHEL

Step 1: Install Nginx

First, install the EPEL repository and then install Nginx:

sudo yum install epel-release -y
sudo yum install nginx -y

Step 2: Start and Enable Nginx

sudo systemctl start nginx
sudo systemctl enable nginx

Step 3: Allow Nginx Through the Firewall

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

Step 4: Verify Installation

systemctl status nginx

Nginx is now successfully installed and running on your Linux VPS! 🎉

5. Configuring Apache or Nginx

Now that you have installed Apache or Nginx, let's configure them to serve websites properly.

Apache Configuration Basics

Creating a Virtual Host (For Hosting Multiple Websites)

Navigate to the Apache sites directory:
```
cd /etc/apache2/sites-available/
```
Create a new virtual host file:
```
sudo nano mywebsite.conf
```

Add the following configuration (replace mywebsite.com with your domain):

<VirtualHost *:80>
    ServerAdmin admin@mywebsite.com
    ServerName mywebsite.com
    ServerAlias www.mywebsite.com
    DocumentRoot /var/www/mywebsite
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Save and exit the file.

Enable the virtual host and restart Apache:

sudo a2ensite mywebsite.conf
sudo systemctl restart apache2

Nginx Configuration Basics

Creating a Server Block (Virtual Host for Hosting Multiple Websites)

Navigate to the Nginx configuration directory:
```
cd /etc/nginx/sites-available/
```
Create a new server block file:
```
sudo nano mywebsite
```

Add the following configuration (replace mywebsite.com with your domain):

server {
    listen 80;
    server_name mywebsite.com www.mywebsite.com;
    root /var/www/mywebsite;
    index index.html index.htm;
    access_log /var/log/nginx/mywebsite_access.log;
    error_log /var/log/nginx/mywebsite_error.log;
}

Save and exit the file.

Enable the server block and restart Nginx:

sudo ln -s /etc/nginx/sites-available/mywebsite /etc/nginx/sites-enabled/
sudo systemctl restart nginx

Now, your website is properly configured on Apache or Nginx! 🚀

6. Setting Up a Firewall for Security

To enhance your server security, configure UFW (Uncomplicated Firewall):

sudo ufw allow 'Apache Full'  # For Apache
sudo ufw allow 'Nginx Full'  # For Nginx
sudo ufw enable
sudo ufw status

For CentOS/RHEL, use firewalld:

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

7. Enabling SSL with Let’s Encrypt (HTTPS Setup)

To secure your website, you should enable SSL with Let’s Encrypt.

Step 1: Install Certbot

For Apache:

sudo apt install certbot python3-certbot-apache -y

For Nginx:

sudo apt install certbot python3-certbot-nginx -y

Step 2: Obtain and Install an SSL Certificate

For Apache:

sudo certbot --apache

For Nginx:

sudo certbot --nginx

Step 3: Set Up Automatic Renewal

sudo certbot renew --dry-run

Now, your website is secured with HTTPS! 🔒

8. Performance Optimization Tips

Enable Gzip Compression

sudo nano /etc/nginx/nginx.conf  # For Nginx
sudo nano /etc/apache2/apache2.conf  # For Apache

Add this inside the configuration file:

gzip on;
gzip_types text/plain application/json;

Restart the server:

sudo systemctl restart nginx  # or apache2

Use a Caching Mechanism (e.g., FastCGI cache for Nginx, Varnish for Apache).

9. Troubleshooting Common Issues

Here are some common problems and how to fix them:

🔴 Apache/Nginx Not Starting?

Run:

sudo systemctl status apache2  # For Apache
sudo systemctl status nginx  # For Nginx

🔴 Port Conflict Issues?

Check which service is using the port:
```
sudo netstat -tulnp | grep ':80'
```

🔴 Permission Issues?

Fix ownership and permissions:

sudo chown -R www-data:www-data /var/www/
sudo chmod -R 755 /var/www/

🔴 Check Logs for Errors

sudo tail -f /var/log/apache2/error.log  # Apache
sudo tail -f /var/log/nginx/error.log  # Nginx
