A virtual private server is an isolated environment with its own operating system and dedicated capacity, simulating a full-fledged physical server. That is, VPS is just a part of the physical server, which, nevertheless, has all its attributes:
On the Internet, all information is transmitted in the form of small blocks of data – the so-called packets. The packet itself consists of the start bits, header, trailer, and payload – each such block with data is transmitted along a specific route, which, in turn, is determined by the router. The network route is "laid" based on the information received from the routing tables according to the routing protocols and instructions of the network administrator.
Regularly updating the CMS is important not only because of the new features and capabilities introduced by developers with the release of patches and versions but also for security reasons. The thing is that there are necessarily some vulnerabilities in any software – hackers are not always aware of them, and developers themselves sometimes face surprises. If a vulnerability has been discovered, with a conscientious approach to the development process, an update will be released shortly after that, eliminating the "gap in defense". Well, the sooner you, as a CMS user, receive this update, the lower the risk that attackers will be able to take advantage of the vulnerability to extract benefits.
One of the most difficult plugins in terms of configuration is W3 Total Cache. At the same time, it is extremely useful for all WordPress sites, as it significantly increases the speed of the resource, reduces its loading time, and reduces the overall server load. After spending a little time studying this material, you will be able to figure out how to configure the W3 Total Cache caching plugin for WordPress.
During the initial configuration of the server, one of the most important steps is the installation of PHP extensions – they are needed for most CMS, including the popular WordPress, Magento, and Laravel. In this article, we will tell you which PHP scripts must be installed and how to do it through the console. We will install it on Ubuntu 20.04, but the syntax of the commands described below can be adapted to any other Linux system.
Sites manually written in HTML are characterized by increased performance and stability. Of course, provided that an experienced and attentive IT specialist writes the code. Such a site is ideal for placing static and materials in small volumes when it is not supposed to make regular changes to the content. HTML sites do not have a control panel, and web pages are edited manually – this creates certain inconveniences for "dynamic" projects, such as online stores, online service storefronts, news sites, etc.
The era of the free Internet is coming to an end – governments of different countries are gradually establishing control over providers in order to restrict citizens' access to certain sites. When it comes to criminal and immoral content that can really harm society, such restrictions are justified. But in recent years, cases of blocking sites for ridiculous reasons have become more frequent – for example, because the domain belongs to an unfriendly state.
When it comes to Linux, most people immediately recall the famous meme from the cult movie "The Hangover", in which Zach Galifianakis appears surrounded by complex mathematical formulas. As if only the chosen ones were able to master the art of Linux management, and for ordinary mortals, this is something incomprehensible. By "the chosen ones" we mean bearded programmers who are able to sort an array with random numbers using the "bubble" method with one eye, and who are able to count linear algorithms in their minds.
CMS – content management systems of websites, they are most often called "engines" in everyday life. There are a large number of such systems, and they all have certain advantages and disadvantages. Whatever the CMS is, its key functions will be:
The distributed version control system Git is often used on hosting sites in order to simplify the updating of the site during development. Without this tool, you will have to download new versions manually, which takes more time. Having configured Git, you will be able to update everything automatically by pressing a single button. Later in the article, we will tell you how to connect Git to hosting and prepare it for work.
