How to Install Tiny Tiny RSS on Debian Latest

First, update the package list by running:
```
sudo apt update
```
Install Apache web server, PHP, and MySQL database:
```
sudo apt install apache2 php-mysql mysql-server
```
Download the latest version of Tiny Tiny RSS from their website:
```
wget https://git.tt-rss.org/fox/tt-rss/archive/master.zip
```
Unzip the downloaded archive:
```
unzip master.zip
```
Rename the extracted folder to tt-rss:
```
mv tt-rss-master tt-rss
```
Move the tt-rss folder to the Apache web server default root directory:
```
sudo mv tt-rss /var/www/html
```

Change the owner of the tt-rss directory to Apache user:

sudo chown -R www-data:www-data /var/www/html/tt-rss

Modify the PHP configuration file to increase the maximum upload file size:
```
sudo nano /etc/php/7.4/apache2/php.ini
```
Locate the following line and modify it accordingly:
```
upload_max_filesize = 2M
```
Change it to:
```
upload_max_filesize = 10M
```
Restart the Apache web server to apply the changes:
```
sudo systemctl restart apache2
```

Create a new MySQL database and a user:

sudo mysql
> CREATE DATABASE ttrss;
> CREATE USER 'ttrssuser'@'localhost' IDENTIFIED BY 'password';
> GRANT ALL ON ttrss.* TO 'ttrssuser'@'localhost';
> FLUSH PRIVILEGES;
> EXIT;

Open a web browser and navigate to http://localhost/tt-rss/install/.
Follow the installation wizard instructions and enter the MySQL database details when prompted.
Once the installation is complete, delete the install folder:
```
sudo rm -rf /var/www/html/tt-rss/install
```
Visit http://localhost/tt-rss to access your new Tiny Tiny RSS installation.

Congratulations! You have successfully installed Tiny Tiny RSS on Debian Latest.
