Revised script for LEMP install with PHP7.4 and PHP8.0

Currently successfully needs more testing on a Debian OS 11.5.0 installation. (I now remember why I didn’t want to touch this stuff any more. But oh well, I may as well completely overhaul this script again. The current one does work, but not well enough for me)

Step-by-step is functioning, will now wipe the server to start from scratch again. Also, the previous article will now be deleted.

Note:
If you are using this on a fresh Debian install, SUDO might not have been installed, nor has the user (so not the root) been add to SUDO. This is how you do that if you are logged in as user:

su -
apt update
apt install sudo
usermod -aG sudo <username>
exit
exit

You need to exit twice so you log out as root and as user. After that, you need to log back in as user so you can start using sudo from now on.


Let’s begin! You can name the script something like

setup.sh
#!/bin/bash

# Update system
sudo apt update
sudo apt upgrade -y

# Install necessary packages
sudo apt install gnupg nginx mariadb-server php7.4-fpm php7.4-mysql php7.4-curl php7.4-gd php7.4-mbstring php7.4-xml php7.4-zip ssh ufw nano fail2ban curl wget sudo openssl net-tools unzip -y

# Add repository key for PHP 8.0
sudo apt install software-properties-common -y
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg

# Add repository for PHP 8.0
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list
sudo apt update

# Install PHP 8.0 and extensions
sudo apt install php8.0-fpm php8.0-mysql php8.0-curl php8.0-gd php8.0-mbstring php8.0-xml php8.0-zip -y

# Configure UFW to allow web traffic and SSH
sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'
sudo ufw allow 3306/tcp

# Enable UFW
sudo ufw enable

# Configure automatic security updates
echo 'APT::Periodic::Update-Package-Lists "1";' | sudo tee -a /etc/apt/apt.conf.d/10periodic
echo 'APT::Periodic::Download-Upgradeable-Packages "1";' | sudo tee -a /etc/apt/apt.conf.d/10periodic

# Disable root login via SSH
sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin no/' /etc/ssh/sshd_config
sudo systemctl restart sshd

# Generate SSH key pairs
ssh-keygen -t rsa -b 4096

# Configure Nginx
sudo systemctl start nginx
sudo systemctl enable nginx

# Configure PHP 7.4
sudo systemctl start php7.4-fpm
sudo systemctl enable php7.4-fpm

# Configure PHP 8.0
sudo systemctl start php8.0-fpm
sudo systemctl enable php8.0-fpm

# Configure MariaDB
sudo mysql_secure_installation

# Allow Nginx to use PHP
sudo sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/' /etc/php/7.4/fpm/php.ini
sudo sed -i 's/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/' /etc/php/8.0/fpm/php.ini

# Restart Nginx and PHP services
sudo systemctl restart nginx
sudo systemctl restart php7.4-fpm
sudo systemctl restart php8.0-fpm

# Create a temporary file to store server and PHP info
tmpfile=$(mktemp)

# Get server info
uname -a > "$tmpfile"

# Get PHP version
php -v >> "$tmpfile"

# Append server and PHP info to index.html
cat "$tmpfile" | sudo tee /var/www/html/index.html >/dev/null

# Remove temporary file
rm "$tmpfile"

# Install adminer 
sudo apt install adminer -y
sudo ln -s /usr/share/adminer/adminer.php /var/www/html/adminer.php
sudo chown -R www-data:www-data /usr/share/adminer /var/www/html/adminer.php

# Set the permissions correct for www
sudo chmod g+w /var/www
sudo chown -R :www-data www
sudo chmod g+s www

change_ownership() {
    sudo chown -R "$1":www-data /var/www
    echo "Ownership of the www folder has been set to $1:www-data."
}

# Loop until a valid username is provided
while true; do
    # Prompt the user to enter the desired username
    read -p "Enter the username for permissions: " username

    # Check if the username provided exists
    if id "$username" &>/dev/null; then
        change_ownership "$username"
        break  # Exit the loop if a valid username is provided
    else
        echo "Error: User $username does not exist."
    fi
done
echo "LEMP setup completed successfully."
echo "Check if Adminer is working by opening a browser, and entering http://IP_address/adminer.php in the address bar"

To make the script executable:

sudo chmod +x setup.sh

and run it with

sudo ./setup.sh

When things like PHP fail to work (becuase y’know… PHP)
These are the files that have to look this way to make PHP happen.

sudo nano /etc/nginx/sites-available/default

#	server {
#		listen     localhost:143;
#		protocol   imap;
#		proxy      on;
#	}
#}
}

And when you enter the following commands, you restart NGINX and PHP FPM and there should be no error message.

sudo systemctl restart nginx

# Adjust the PHP version if necessary. In my case, I want PHP 8.0

sudo systemctl restart php8.0-fpm

Good luck 🙂

Update in the script to block bots, spiders and indexers

Original post: https://3xn.nl/projects/2023/09/20/crude-solution-to-ban-bots-by-their-user-agent/

I’ve very much simplified the script that instantly redirects unwanted traffic away from the server. Currently, I am using a very cheap VPS to receive all that traffic.

Here ya go:

// This is a functional but dirty hack to block bots, spiders and indexers by looking at the HTTP USER AGENT.
// Traffic that meets the conditions is being yeeted away to any place of your choice.

//////////////////////////////////////////////////////////////
// Emergency bypass
// goto end;
//////////////////////////////////////////////////////////////

// attempt to basically just yeet all bots to another website

$targetURL = "https://DOMAIN.TLD/SUB/";

// Function to check if the user agent appears to be a bot or spider

function isBot()

{

    $user_agent = $_SERVER['HTTP_USER_AGENT'];

$bot_keywords = ['bytespider', 'amazonbot', 'MJ12bot', 'YandexBot', 'SemrushBot', 'dotbot', 'AspiegelBot', 'DataForSeoBot', 'DotBot', 'Pinterestbot', 'PetalBot', 'HeadlessChrome', 'GPTBot', 'Sogou', 'ALittle Client', 'fidget-spinner-bot', 'intelx.io_bot', 'Mediatoolkitbot', 'BLEXBot', 'AhrefsBot'];

    foreach ($bot_keywords as $keyword) {

        if (stripos($user_agent, $keyword) !== false) {

            return true;

        }
    }

    return false;

}

// Check if the visitor is a bot or spider

if (isBot()) {

// yeet

header("Location: $targetURL");

    // Exit to prevent further processing

    exit;

}

end:

// If the visitor is not a bot, spider, or crawler, continue with your website code.

More tweaks for the .htaccess file!

Here’s a list of stuff that I have in my .htaccess files on various websites.

Crude solution to ban bots by their user-agent

Okay, this is a very crude way to block bots, spiders and crawlers by their user-agent, but so far, this has been very, very efficient.

Even when one chooses ” yes “, the question will be repeated. This is not a problem, because no one in their right mind is going to add “bot”, “spider” or “crawler” as their user-agent.

So here’s the PHP script that I rammed into a certain website to prevent it from being DDOSsed by (malicious) bots.

<?php

// CC-BY-NC (2023)
// Author: FoxSan - fox@cytag.nl
// This is a functional but dirty hack to block bots, spiders and indexers by looking at the HTTP USER AGENT.
// The form is, iirc, not even working, but that's fine if you only want human visitors.
// It can also throw a 403, but the effect is the same.

////////////////////////////////////////////////////////////////////////////////
// Emergency bypass
// goto end;
////////////////////////////////////////////////////////////////////////////////

// Function to check if the user agent appears to be a bot or spider.
// Enter the bots you would like to block in a list as shown below.
function isBot()
{
    $user_agent = $_SERVER["HTTP_USER_AGENT"];
    $bot_keywords = ['bytespider', 
                     'amazonbot', 
                     'MJ12bot', 
                     'YandexBot', 
                     'SemrushBot', 
                     'dotbot',

            // User selected "Yes," block access
            echo "Access denied. If you believe this is an error, please contact us by writing the word [MAILBOX] before the at sign, followed by [DOMAIN.TLD]";
        } elseif ($choice === "no") {
            // User selected "No," proceed to end
            goto end;
        }
    } else {
        // Output the message to the user and make the choice mandatory
        echo "Your user agent suggests you might be a bot, spider, or crawler. Are you one of these three?";

        // Output the radio button choices within a form

A working Apache2 server with PHP7.4

I was in need of a server solution that could be quickly deployed as a VM.

      1. Install Debian 11 as a VM with web- and SSH server
      2. Create a USER next to your root account during the installation
      3. Find the IP address of the new installation. The easiest is if you have NoVNC running. Log in as USER and type
        ip a
      4. Time to so the sudo thing
        su

        log in as root

        apt-get update && apt-get install -y sudo
        usermod -aG sudo USER
        exit
        exit

        log back in as USER

      5. Okay, let’s install some more stuff but first we do an update
        sudo apt-get update && sudo apt-get upgrade -y

        Now we want some essentials

        sudo apt-get install -y dirmngr gnupg2 nano wget gpg curl fail2ban ufw software-properties-common

        Preparing the PHP install

        wget -q https://packages.sury.org/php/apt.gpg -O- | sudo apt-key add -
        echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list
        sudo apt-get update
        sudo apt-get install -y php7.4 libapache2-mod-php7.4 php7.4-mysql php7.4-curl php7.4-gd php7.4-mbstring php7.4-xml php7.4-xmlrpc php7.4-zip

        And restart the Apache2 Webserver

        sudo systemctl restart apache2
      6. Alright, that’s done. Next step is to test things.
        sudo nano /var/www/html/test.php

        Enter this into the php file and press Control X and type Y to save and exit.

        <?php
        // Show all PHP information
        phpinfo();
        ?>
      7. Go to the IP address of the server you just created and type
        HTTP://IP ADDRESS/test.php
        

        If you see a PHP page with all sorts of data, you’re good. If not, go fix. Don’t ask me, I’m not there yet!
