Making changes to bitnami’s WordPress settings

1. Accessing and Editing the php.ini file to change something like max-execution:

• SSH into your Lightsail instance: Use an SSH client to connect to your server.
• Navigate to the PHP configuration folder: cd /opt/bitnami/php/etc/.
• Open the php.ini file with a text editor: Use tools like nano or vim to edit the file – sudo php.ini
• Locate the max_execution_time directive: This line will be set by default to a number like 30 or 120 seconds.
• Change the value: Modify the number to your desired execution time (e.g., max_execution_time = 300 for 5 minutes).
• Save the changes: In nano, press Ctrl + O to save and then Enter to confirm. 

2. Accessing and editing wp-config:

• access and edit the wp-config gfile sudo nano /opt/bitnami/wordpress/wp-config.php
• find the settings that you want to change (or add) and do it. In particular I have to do this on lightsail to change the site settings from http:// to https://
• Once you’re done; Ctrl +O, Enter then Ctrl + X

3. Restarting Relevant Services:

• Restart Apache and php-fpm: After making changes to php.ini or wp-config.php, you’ll need to restart the Apache web server and the php-fpm process. You can do this with the following commands:
  • sudo /opt/bitnami/ctlscript.sh restart apache
  • sudo /opt/bitnami/ctlscript.sh restart php-fpm
