Similar to Dropbox and Google Drive, Nextcloud is self-hosting software that allows you to share files, contacts, and calendars. But, unlike Dropbox and Google Drive, your files will be private and stored on your server instead of a third-party server. Nextcloud is a GDPR and HIPAA compliant hosting solution, so your files will be encrypted along with the ability to audit. For this tutorial, we’ll be installing our Nextcloud instance on our Ubuntu VPS server.

Sites with SSL are needed more and more every day. Its ubiquitous enforcement challenges website encryption and is even an effort that Google has taken up. Certbot and Let’s Encrypt are popular solutions for big and small businesses alike because of the ease of implementation.  Certbot is a software client that can be downloaded on a server, like one of our Ubuntu VPS servers, to install and auto-renew SSLs. It obtains these SSLs by working with the well known SSL provider called Let’s Encrypt. In this tutorial, we’ll be showing you a swift way of getting HTTPS enabled on your site.  Let’s get started!

What Does Varnish Do?

Varnish is a website accelerator. It’s designed to decrease the time it takes for your website to load and an ideal tool for improving performance on busy, mission-critical sites.

Mod_security, also commonly called Modsec for short, is a powerful WAF (Web Application Firewall) that integrates directly into Apache’s module system. This direct integration allows the security module to intercept traffic at the earliest stages of a request. Early detection is crucial for blocking malicious requests before they are passed along to web applications hosted by Apache websites. This provides and extra layer of protection against common threats a server faces. This article will explore the installation of mod_security along with the CRS (Core Rule Set) in an Ubuntu 16.04 LTS Server running Apache 2.4.

Using PHP 7.2 on an Ubuntu dedicated server is highly recommended over previous PHP versions for several reasons, first being security. Active Support for PHP 7.2 goes until November 30th, 2019 and Security Support until Nov. 30, 2020. Older versions like 7.0 and anything 5.6 and below are no longer getting any support and can leave open security holes on a server if they are not replaced. Another main reason to upgrade is the big performance increase over previous versions when PHP 7.2 is installed and is using the OPcache module.  This can greatly decrease the time it takes for your web page to load! If you are developing a site locally or launching it on one of Liquid Web’s Ubuntu VPS or Dedicated Servers, using PHP 7.2 or newer would be the way to go.

What is Poweradmin?

Poweradmin is a web-based graphical user interface to interact with PowerDNS. It is released under the open source GPL license. It makes it easy to create and edit zone files and interacts directly with the SQL server. Poweradmin has full support for most PowerDNS features, including all zone types (master, native and slave), supermasters, for automatic provisioning of slave zones and full support for A, AAAA, CNAME, HINFO, MX, NS, PTR, SOA, SRV and TXT record types, validation against RFC’s. It also has user and permission management setup for controlling user permissions with templates.  In this tutorial, we’ll be showing you how to install and configure Poweradmin as well as some records.

How directives behave and which directives are mainly available hinges on the loaded MPM. As discussed in our previous series, MPM is short for MultiProcess Modules, and they determine the basis for how Apache addresses multiprocessing. Using our last article on Apache MPM Modules as a springboard, we will use this section to cover the following subsections:

The keystone for understanding Apache server performance is by far the Multiprocessing Modules (MPMs). These modules determine the basis for how Apache addresses multiprocessing. Multiprocessing means running multiple operations simultaneously in a system with multiple central processing units (CPU Cores).

Nginx is an open source Linux web server that accelerates content while utilizing low resources. Known for its performance and stability Nginx has many other uses such as load balancing, reverse proxy, mail proxy, and HTTP cache. With all these qualities it makes a definite competitor for Apache. To install Nginx follow our straightforward tutorial.
