A free service for making scheduled posts to Reddit. It's available at https://cronnit.us or you can download the code and host it yourself!

If you have a fresh server you can run the install script:

wget https://raw.githubusercontent.com/krisives/cronnit.us/master/install.sh
nano install.sh # Enter your hostname, client_id, etc.
sudo ./install.sh

This will:

• Install all the packages needed for Apache, MySQL, PHP, etc.
• Create a 2GB swapfile to ensure the server doesn't run out of memory
• Create the Linux user cronnit
• Create a cronnit MySQL database
• Create a cronnit MySQL user (with a secure random 30 character password)
• Grant permissions for cronnit to use the database
• Import the Cronnit SQL schema
• Disable insecure Apache modules (mod_status, mod_userdir)
• Acquire an SSL certificate from LetsEncrypt using certbot
• Configure Apache to run Cronnit including the SSL certificate
• Downloads the latest version of Cronnit from GitHub
• Generates a config.php script for Cronnit
• Installs all of the composer dependencies
• Creates a CRON job to run the cron.sh script
• Creates a CRON job to update from GitHub every day
• Configures the system to install security updates automatically

Before running the script you should ensure the DNS record for your domain name point to the IP running this server.

For client_id and client_secret you will need to create a Reddit app using a redirect URI of https://example.com/authorize ensure you are using https:// in the URI.

You can skip using https:// and certbot if you want by running the script with the HTTP_ONLY environment variable set:

sudo HTTP_ONLY=1 ./install.sh

If you want to run Cronnit using the PHP development server:

sudo apt install php-cli php-sqlite3 composer
git clone [email protected]:/krisives/cronnit.us.git
cd cronnit
composer update
cp config.php.example config.php
nano config.php
cd public_html/
php -S localhost:8080
