Editing php.ini file

Question

I need to edit the max_upload_size in the php.ini file but I'm getting permission denied error when uploading new file using FTP
The wordpress install in on the Lightsail blueprint - not Bitnami
I have located  2 php.ini files on the server
/etc/php/8.2/cli/php.ini
/etc/php/8.2/apache2/php.ini 
which one should I edit and how do I do it?

For a WordPress installation on Lightsail (non-Bitnami), you should edit the `/etc/php/8.2/apache2/php.ini` file, as this is the configuration file that Apache web server uses when serving PHP content through your WordPress site. The CLI version is used for command-line PHP scripts.

To edit this file, you'll need to use SSH to connect to your instance rather than FTP, since you need elevated permissions. Here's how:

1. Connect to your Lightsail instance using the browser-based SSH client from the Lightsail console, or use your preferred SSH client.

2. Create a backup of the file first:
```
sudo cp /etc/php/8.2/apache2/php.ini /etc/php/8.2/apache2/php.ini.backup
```

3. Edit the file using a text editor like nano or vim with sudo privileges:
```
sudo nano /etc/php/8.2/apache2/php.ini
```
or
```
sudo vim /etc/php/8.2/apache2/php.ini
```

4. Find and modify the `upload_max_filesize` directive (and you may also want to increase `post_max_size` to match or exceed this value).

5. Save the file and exit the editor.

6. Restart Apache to apply the changes:
```
sudo systemctl restart apache2
```

The permission denied error you're experiencing with FTP occurs because system configuration files require root privileges to modify, which FTP typically doesn't provide. Using SSH with sudo is the proper method for editing system files.
