Step-by-Step Guide

Update Package List

First, ensure that your package list is up-to-date.

sudo apt-get update

Install php-mysqli Extension

Install the php-mysqli extension for PHP 7.4.

sudo apt-get install php7.4-mysqli

Verify Installation

After installation, you should verify that the extension is enabled. You can do this by creating a PHP info file.

sudo nano /var/www/html/info.php

Add the following content to the file:

php

Copy code

<?php

phpinfo();

?>

Save and close the file. Then, navigate to http://your-ec2-instance-public-dns/info.php in your web browser and check for mysqli in the output.

Restart Apache

Restart Apache to apply the changes.

sudo systemctl restart apache2

Step-by-Step Guide

Check Directory Permissions

Ensure you have the necessary permissions to delete the directory. You can check the permissions using the ls -ld command.

ls -ld /path/to/directory

If you do not have write permission (w) on the directory or the parent directory, you will need to adjust the permissions or use sudo.

Change Permissions (if needed)

If you need to change the permissions, you can use the chmod command.

sudo chmod -R 777 /path/to/directory

This command gives read, write, and execute permissions to all users for the directory and its contents. This should be used cautiously, and permissions should be reverted to a more secure state after the operation.

Remove the Directory with rm

Use the rm command with the -r (recursive) and -f (force) options to remove the directory and its contents.

sudo rm -rf /path/to/directory

-r (or --recursive): Remove directories and their contents recursively.

-f (or --force): Ignore nonexistent files and arguments, never prompt.

Check if the Directory is in Use

If the directory is in use by another process, you might not be able to remove it. You can check for running processes that might be using the directory.

lsof +D /path/to/directory

This will list open files and the processes using them. You can stop these processes if needed.

Option 1: Change File/Directory Ownership and Permissions

Change Ownership

Change the ownership of the target directory to the user you are using to log in via WinSCP. Typically, this is the ubuntu user for an Ubuntu EC2 instance.

sudo chown -R ubuntu:ubuntu /var/www/html/your-laravel-project

Change Permissions

Set the permissions so that the user has the necessary rights to move or modify files.

sudo chmod -R 755 /var/www/html/your-laravel-project

Reconnect with WinSCP

Reconnect to your EC2 instance using WinSCP and try to move the files again.

Option 2: Use Sudo in SCP (via Command Line)

If changing the permissions is not feasible, you can use the command line to perform the operation with sudo. Unfortunately, WinSCP does not support sudo directly, but you can use the command line for this.

Move Files Using SSH

Connect to your EC2 instance via SSH and move the files using sudo.

ssh -i /path/to/your-key.pem ubuntu@your-ec2-instance-public-dns

sudo mv /path/to/source /path/to/destination

Using SFTP with Sudo

Use an SFTP command line tool that supports sudo. Here is an example using scp:

# Copy file from local to remote using scp

scp -i /path/to/your-key.pem /local/path/to/file ubuntu@your-ec2-instance-public-dns:/remote/path

# Connect to EC2 instance

ssh -i /path/to/your-key.pem ubuntu@your-ec2-instance-public-dns

# Move file to target directory with sudo

sudo mv /remote/path/to/file /var/www/html/your-laravel-project

Option 3: Temporarily Change Permissions

If you prefer to use WinSCP and don't want to permanently change ownership, you can temporarily change the permissions of the target directory and then revert them after the operation.

Temporarily Change Permissions

sudo chmod -R 777 /var/www/html/your-laravel-project

Perform the Operation with WinSCP

Reconnect with WinSCP and move the files.

Revert Permissions

After the operation, revert the permissions to a secure state.

sudo chmod -R 755 /var/www/html/your-laravel-project

sudo chown -R www-data:www-data /var/www/html/your-laravel-project
