AWS SDK Load Config

Occasionally I was getting this random error when running Terraform.

╷
│ Error: error configuring Terraform AWS Provider: no valid credential sources for Terraform AWS Provider found.
│ 
│ Please see https://registry.terraform.io/providers/hashicorp/aws
│ for more information about providing credentials.
│ 
│ Error: RequestError: send request failed
│ caused by: Post "https://sts.amazonaws.com/": read tcp xx.xx.xx.xx:59422->xx.xx.xx.xx:443: read: connection reset by peer

│ 
│   with provider["registry.terraform.io/hashicorp/aws"],
│   on main.tf line 10, in provider "aws":
│   10: provider "aws" {

Here’s the fix. Place this in your ~/.bash_profile.

export AWS_SDK_LOAD_CONFIG=1

This forces Terraform to use both config and credentials file.

Where’s php.ini?

How to find where php.ini is being from the command line.

$ php -i | grep 'grep 'Configuration File'
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.ini

Change WordPress URL

There are multiple ways to change URL in WordPress.

Here’s one via wp-config.php.

define( 'WP_HOME', 'http://example.com' );
define( 'WP_SITEURL', 'http://example.com' );

If you have a redirect in Apache, comment it out.

#Redirect permanent / https://yourdomain.com/

This is by far the easiest way to change URL in WordPress.

Standard SSL Policy

Here’s a standard template for SSL Apache found in /etc/apache2/sites-available/default-ssl.conf.

<IfModule mod_ssl.c>
<VirtualHost _default_:443>
   ServerAdmin your-email@your-domain.com
   ServerName www.yourdomain.com
   ServerName yourdomain.com
   DocumentRoot /var/www/your-domain.com
   ErrorLog /var/www/your-domain.com/log/error.log
   CustomLog /var/www/your-domain.com/log/access.log combined
   <Directory /var/www/your-domain.com>
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Require all granted
   </Directory>
   SSLCertificateFile /etc/letsencrypt/live/your-domain.com/fullchain.pem
   SSLCertificateKeyFile /etc/letsencrypt/live/your-domain.com/privkey.pem
   Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

Enable SSL.

# Enable SSL Module
a2enmod ssl
systemctl restart apache2.service
# Enable SSL Apache Config
a2ensite default-ssl
systemctl restart apache2.service
# Alternate way to restart.
service apache2 restart

WordPress Asking for FTP Details

If WordPress is asking for FTP details when you’re trying to update a theme, plugin, or WordPress itself, you will need to edit your wp-config.php file to add the following line to your configuration.

define('FS_METHOD','direct');

Save the file and try updating again. It shouldn’t ask you for FTP details.
