impit - browser impersonation made simple https://github.com/apify/impit

curl_cffi — TLS fingerprint spoofing. Popular in Python scraping community. Relatively new (2023+), growing fast.

tls-client — similar concept, Go-based TLS client with Python bindings. Used a lot in sneaker bots and ticket scalping.

got-scraping — Node.js equivalent, spoofs TLS fingerprints. Used by Apify (major scraping platform).

Tier 2 — Headless browsers (real browser engine)

Puppeteer — Chrome/Chromium via DevTools protocol. The OG.

Playwright — Microsoft's answer to Puppeteer. Supports Chrome, Firefox, Safari. Becoming the standard.

Selenium — older, slower, but still widely used.

1. Check the Available Storage:
Before expanding, verify the disk space:

df -h

2. Identify the Volume:
Find the attached volumes for your EC2 instance:

Go to the EC2 Console.
Under Elastic Block Store (EBS), select Volumes.
Identify the volume attached to your instance.

3. Modify the EBS Volume:
Select the volume you want to expand.
Click on Actions → Modify Volume.
Increase the size of the volume (e.g., from 8 GB to 20 GB).
Click Modify.

4. Extend the Partition on the EC2 Instance:
After the volume is resized, you'll need to extend the file system to use the new space.

For ext4 file system:
Verify the volume size:

lsblk

Make sure the resized volume reflects the correct size.
Extend the file system:

sudo growpart /dev/nvme0n1 1
sudo resize2fs /dev/nvme0n1p1

For xfs file system:
Extend the file system:

sudo xfs_growfs -d /

5. Verify the Increased Space:
Check the disk space again:

df -h

This process will allow you to increase the disk space without stopping the instance.

To check partition type

lsblk -f

Step 1: Add PHP 7.4 Repository
First, you need to add the ondrej/php PPA, which allows you to install older PHP versions like 7.4.

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

Step 2: Install PHP 7.4 and PHP 7.4-FPM
Now, install PHP 7.4 along with its FPM package and any required extensions.

sudo apt install php7.4 php7.4-fpm php7.4-cli php7.4-common php7.4-mysql php7.4-xml php7.4-mbstring php7.4-curl

Step 3: Ensure PHP 8.3 FPM is Installed
Make sure you also have PHP 8.3 FPM installed (if not already):

sudo apt install php8.3-fpm

Step 4: Configure Nginx to Use Different PHP-FPM Versions
Now, you need to modify your Nginx configuration to point to the correct PHP-FPM socket for each site or location.

For PHP 8.3 (default):
In your Nginx config file (e.g., /etc/nginx/sites-available/default), set the fastcgi_pass directive to PHP 8.3:

nginx
Copy code
location ~ .php$ {
fastcgi_pass unix:/run/php/php8.3-fpm.sock;
include fastcgi_params;
}

For PHP 7.4 (for specific locations or sites):
For specific sites or locations where you want to use PHP 7.4, you can point to the PHP 7.4 FPM socket:

location ~ \.php$ {
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
    include fastcgi_params;
}

Step 5: Enable and Restart PHP-FPM Services
Enable both PHP-FPM services to ensure they start on boot:

sudo systemctl enable php8.3-fpm
sudo systemctl enable php7.4-fpm

Then restart both services:

sudo systemctl restart php8.3-fpm
sudo systemctl restart php7.4-fpm

Step 6: Set PHP 8.3 as the Default CLI Version (Optional)
If you want to keep PHP 8.3 as the default for the CLI, use the update-alternatives command:

sudo update-alternatives --set php /usr/bin/php8.3

To switch to PHP 7.4 for the CLI:

sudo update-alternatives --set php /usr/bin/php7.4

Step 7: Verify Installation
To check the installed versions of PHP-FPM, run:

php -v          # To check the default CLI version
sudo systemctl status php7.4-fpm
sudo systemctl status php8.3-fpm

Conclusion
Now you have both PHP 8.3 and PHP 7.4 running on your Ubuntu 24 system, with PHP 8.3 as the default and the ability to use PHP 7.4 for specific locations or virtual hosts.

Modify the Port to new port number (i.e: 23)

Port 23

Restart ssh service

/etc/init.d/ssh restart

If not working, modify file below;

vim /etc/systemd/system/sockets.target.wants/ssh.socket

Modify the "ListenStream" value to target (i.e: 23)

Restart systemctl daemon & ssh service

systemctl daemon-reload
/etc/init.d/ssh restart

Need to copy Bitbucket's id_rsa key to server's authorised_keys.

1. Go to Repository Settings (of the particular repo)
2. Pipeline > SSH Keys

Generate key.

Copy the generated key to authorised_keys in target server.

3. Get the server's fingerprint, so Bitbucket can keep it. - enter the server IP, and click "Fetch"

Create this file in the server, so it always execute this by default.

Then

The output files will in "./build" directory.

Certbot will modify nginx /site-available/default file, and append the 443 entry.

It also will install certbot's service for auto renew.

# systemctl status certbot.timer

To test the auto-renew.

certbot renew --dry-run
