AMI Linux 2023 PDO MariaDB Error

Question

I have an AMI Linux 2023 running with MariaDB. I can't make a PDO connection from my PHP script to my RDS running MariaDB. I followed this tutorial to Install LAMP 2023: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-lamp-amazon-linux-2023.html

The tutorial says to install following packages:

```
sudo dnf install -y httpd wget php-fpm php-mysqli php-json php php-devel
```

I assume that only 
```
php-mysqli
```
driver was installed for PHP but not the PDO driver. I am kind of new to AWS. How can I install the PDO driver on my instance?  I looked up all available packages here:  https://docs.aws.amazon.com/linux/al2023/release-notes/all-packages-AL2023.2.html. I located  
```
php8.2-pdo
```
 package. Do I just need to run 
```
sudo dnf install -y php8.2-pdo
```

? Do I need to make additional changes after installation?

Answer

Hello.

What kind of error?  
If it is a timeout error, there may be a problem with the network settings such as the RDS security group.  
Please configure the inbound rules of the RDS security group to allow connections from EC2.
