What's New in Plesk Onyx

With Plesk Onyx 17.8 release we are introducing multiple changes aimed to assist both new and existing Plesk users and improve their User Experience on many fronts. For example, the Plesk Advisor extension helps you make sure that everything, from the server itself to the hosted web apps, always stays secure, while the simplified on-boarding process helps newcomers to quickly set up and run their websites. Automatic securing of websites with free SSL/TLS certificates improves the security aspect even further, making the lives of existing users much easier. As more and more Plesk features are being delivered as extensions to ensure that business-critical functionality reaches everyone in a timely manner, the Plesk Extension Catalog was improved to provide you with a smooth and enjoyable experience. We are also continuously improving the Plesk experience for those who use Plesk in various cloud services. Read on to get a closer look at the changes in the Plesk Onyx 17.8 release.

SSL Everywhere

We have significantly improved the experience of working with SSL/TLS certificates, making sure that it takes minimal effort to keep things secured:

Protecting your websites with SSL/TLS certificates not only gives visitors peace of mind – it helps your Google rating as well! Here at Plesk we run a tight ship, and enable you to do so, too.

Nginx Caching

Reduce your hosted websites' response time and server load using Nginx Caching:

  • With caching, certain types of PHP pages can be served to visitors as quickly as static pages.

Protect yourself and your customers from junk mail with modern email validation tools. Sadly, the vast majority of email being sent over the internet is spam.

Some of it is merely annoying, but a lot of bulk mail is actually malicious, used by scammers and phishers to defraud people. To help you keep your customers safe, Plesk Onyx joins the fight with DKIM, SPF, DMARC, and SRS support.

  • DKIM and SPF are modern email validation methods designed to detect email spoofing and prevent spammers from being able to pretend that their mail is sent from a specific trusted domain, when in fact it is not.
  • DMARC is an email validation scheme built on top of SPF and DKIM. It allows webmasters to declare what validation method(s) must be used when checking mail purportedly sent from their domain, and what to do with mail that fails validation.
  • SRS is a scheme for rewriting the envelope sender address of an email message as it is being forwarded, so that bounced mail can be delivered to the sender regardless of their SPF policy.

Git Support

To make deploying your website even easier, Plesk Onyx introduces integration with Git – the most popular source code management system. This feature enables you to do the following:

  • Easily deploy your website content by either pushing it to a local Git repository or by pulling from a remote one.
  • Use GitHub, BitBucket, Travis, or any other software engineering service of your choice.
  • Create multiple branches in a single repository – useful for separating staging and production code.
  • Deploy manually for complete control or enable automatic deployment to save time.
Learn more.

Docker Support

To help you meet the evolving requirements of your customers, Plesk Onyx comes with Docker support. Here is what you can do with it:

  • Have on-demand access to a wide range of modern technologies, such as redis, mongodb, memcached, and many more.
  • Choose from a catalog of available images, or upload a custom image.
  • Deploy and manage Docker containers straight from the Plesk interface.
  • Install Docker containers locally, or to a remote node registered in Plesk.

Windows Server 2016

Plesk Onyx supports the Standard and Datacenter editions of Windows Server 2016, which introduce the IIS 10 web server. This new web server from Microsoft comes with a number of important new features, such as:

  • Wildcard subdomains
  • HTTP/2 support
  • New cipher suites

All of these are incentives to upgrade, and are supported by Plesk Onyx. For the future, we have more features planned, such as SSH and native Docker support on Windows – stay tuned for updates!

System Updates

Plesk Onyx provides server administrators with an easy-to-use tool for keeping their servers up to date. You can update any system packages present on the server either manually or automatically without having to open the console. The tool uses OS package managers (yum and apt) to perform updates, which makes the procedure of updating as robust as if it were done through native OS tools.

The tool provides extra flexibility if you don't want to update certain packages. It is possible to prevent packages from being updated by locking them via two clicks in UI.

Plesk ships a variety of components that were modified or built by Plesk team itself (for example, PHP version packages). You can also use this tool to monitor and update these packages at any time you want without waiting for Plesk updates.

Updated Log Browser

The Log Browser tool added in Plesk 12.5 has been updated in Plesk Onyx. It is now possible for all hosting users to open any arbitrary log file located on their virtual host in Log Browser for easier monitoring. Users can save any opened log file in the list of logs for accessing it in the future. If the log is not required anymore, it can be removed from the list.

Note that only plain text log files can be opened by Log Browser, binary log files are not supported. This functionality is especially useful for those who install and use various frameworks like Yii, Symfony, and so on.

Another improvement of the Log Browser tool is the highlighting of various files mentioned in logs. This can happen, for example, if there's an error in a particular file. The highlighted files can be opened in the embedded editor by clicking them, which makes debugging websites even faster.

System Resource Usage Limits

Limiting the usage of system resources is a big pain point for every shared hoster. Plesk Onyx aims to solve this issue by introducing the ability to limit the amount of system resources that can be used by a particular subscription. This should greatly help to prevent server abuse caused by malicious or poorly written scripts and applications.

The following system resources can be limited by this feature:

  • CPU
  • RAM
  • Disk I/O

This ability is based on CGroups (Control Groups) feature of Linux kernel, so it's available only on OSes with systemd (for example: Centos 7, Debian 8 and Ubuntu 16.4).

DNSSEC Support

The DNSSEC acronym stands for Domain Name System Security Extensions. It is a set of DNS protocol extensions that were introduced by IETF with the goal of signing DNS data to secure the domain name resolving process.

DNSSEC was made to help make the Internet a safer and more secure place. Since we are committed to providing the best in security to our clients, Plesk Onyx offers the support for DNSSEC, allowing users to protect the DNS data of hosted domains with DNSSEC extension. The extension gives users the ability to do the following:

  • Configure the settings used for key generation and rollover
  • Sign and unsign domain zones according to the DNSSEC specifications
  • Receive notifications related to DNSSEC records and keys
  • View and copy DS resource records and DNSKEY resource record sets

Ruby Support

Ruby is a popular programming language among web developers. Plesk Onyx introduces proper Ruby language support as a Plesk extension.

The Ruby extension available in Plesk Onyx allows users to quickly and easily deploy Ruby apps on their domains. Both Ruby on Rails and Sinatra frameworks are supported. With this extension you can:

  • Enable Ruby support on any given virtual host
  • Choose which Ruby version should be used on a domain. Both UI and CLI calls use rbenv utility to achieve maximum conformity
  • Install gem file dependencies via UI using Bundler tool
  • Specify custom environment variables
  • Edit configuration files

It is strongly suggested to install the Tools required for building Ruby gems component in order to facilitate quick and painless Ruby gem installation. With this component you can sit back, forget about gem dependency hell and enjoy painless gem file installation since most dependencies will be resolved for you automatically by our tools.

Node.js Support
