Plesk and Ruby on Rails

railsIn this article I’ll try to explain how to run Ruby on Rails applications on a server managed by Plesk. Plesk itself does not support modern Rails apps natively. But this doesn’t mean that you cannot deploy such applications to Plesk hosting.

We will use an Ubuntu 14.04 server and Plesk 12.0 for our experiments. I assume that you will get this configuration somehow. It’s possible to deploy Rails apps on different OS and using different Plesk version, but all further commands will rely on Ubuntu 14.04 and Plesk 12.0 capabilities.  Read the rest of this entry »

Dropbox Backup 2.0

dropboxDropbox Backup is a Plesk extension that extends the built-in Backup Manager and allows you to use Dropbox storage. Read more about the extension in the previous post.

A new version of the extension was recently released. It is available in the Extensions Catalog. In this post, I would like to announce new features implemented in this version. All of them are based on the feedback collected from the blog and the forum. Please continue providing your ideas.

The extension is compatible with Plesk since version 11.5 on both Linux and Windows platforms.

Plesk 12 and NAT Manager Extension

There might be cases when a Plesk server is located in a private network and it has only one internal IP address. In such cases, website visitors can access the hosted sites via the NAT technology. NAT translates public IP addresses into internal IP addresses and encapsulates this information in network packets.

Plesk uses one and the same IP address for various purposes. For example, an IP address is used for web hosting (Apache + nginx configuration files) and for DNS zone definitions. And here is a problem. In the former case, an internal IP address should be used, and in the latter case, an external IP address. Plesk UI shows only one IP address, but it does not let you configure the mapping (translation) of IP addresses.

Extensions: Development Environment

This article describes how to setup a development environment for creation of Plesk extensions.

Creation of a new Plesk extension can be started from generating a new stub. To do this log in to a machine with Plesk installation and type the following command:

Here is an example of output:

This command will create a new extension named “my-extension”. It will also provide information about where extension parts are located on the file system.

About Plesk URL or Telling Customers the Right Address to Go to

Introduction

A long time ago Plesk had one good little feature: when typing the panel address in your browser address bar, if you specified the port (8443), but omitted the encryption method (https), Plesk would redirect you to the address https://<server_hostname>:8443. In version 11.5, we replaced the lighttpd web server that served Plesk with nginx. And broke that good little feature.

Right away, our users pointed out that breaking good little features and giving nothing in return is bad. Please forgive and forget :) As you can see in Plesk 12.0 preview (available through autoinstaller with –all-versions key), we returned the previous behavior.

What’s our point in telling this story? We wanted to share one interesting use-case proposed by our users and to contribute to it. Read the rest of this entry »

CheckPassword authentication in Dovecot: a practical example in Shell

In this post I’ll show how to set up authentication in Dovecot via custom CheckPassword script written in Shell. While this is not generally suitable for any kind of production deployment for performance reasons, employing CheckPassword authentication is great for prototyping custom authentication that cannot be done via other available standard drivers.

Disclaimer: This post will not contain any new useful information for Plesk users. Configuration described here is not and will not be used in Plesk. This post is primarily aimed for those who develop some kind of integration with Dovecot.

Dropbox Backup Extension

Introduction

From my own experience of VPS usage, I noticed the need for cloud backup storage. The current version of Backup Manager for Parallels Plesk Panel does not support any remote storage except FTP, but I wanted to utilize a cloud storage for that purpose.

As a developer, I wanted to implement a complete solution for the problem and share it with the Plesk community. Starting from version 11.0.9, you can add new functionality to Plesk with extensions – this is exactly what I needed.

For my experiment, I chose Dropbox as a place for my stuff. It has a rather simple REST API with a lot of implementations for different programming languages. I used PHP SDK by Ben, but now the official Dropbox SDK is available.
