How to Install Thumbor on OpenBSD

Thumbor is an open-source image processing system that enables users to manipulate various aspects of an image. It supports multiple filters and transforms and is effortlessly customizable. Here's a step-by-step guide on how to install Thumbor on OpenBSD.

Prerequisites

Before we begin, ensure that your OpenBSD system meets the following requirements:

OpenBSD 6.5 or higher
Python 2.7 or higher
pip package manager

Installation

Install the required packages by running the following command:

sudo pkg_add python py-setuptools py-pil py-cryptography graphicsmagick

Once the packages have been installed, use pip to install Thumbor. Run the command below:
```
sudo pip install thumbor
```
Verify that Thumbor is installed by running the following command:
```
thumbor
```
If the installation was successful, you should see a message that says Server ready.
By default, Thumbor runs on port 8888. To change the port, you need to create a configuration file. Run the command:
```
thumbor-config > /etc/thumbor.conf
```
Once the configuration file has been created, proceed to edit it with your preferred text editor. Configure the applicable options, such as the port number, maximum image size, and allowed domains. For instance, you can edit the port by modifying the following line in the configuration file:
```
HTTP_SERVER_PORT = 8888
```
Save the changes and exit the file.
Start Thumbor by running the following command:
```
thumbor -c /etc/thumbor.conf
```
Verify that Thumbor is listening on the specified port by running the command below:
```
netstat -na | grep LISTEN | grep 8888
```
If everything is okay, you should see output indicating that the port is open.

That's all! You have successfully installed and configured Thumbor on OpenBSD. You can now use it to process images easily.
