SSL certificates have become a de facto part of every website. If you don’t yet have an SSL on your site to encrypt data, you should. Rather than showing an extra layer of security on sites protected by SSL, modern browsers instead now display a warning when a website does not have an SSL, essentially requiring sites to maintain their positive image.
When moving from one server to another, what needs to happen to your SSL to maintain your secure status? We’ll cover the basics for transferring traditional and Let’s Encrypt SSLs to Ubuntu 16.04 and CentOS 7.
This article will address SSLs in Apache specifically, but the same concepts apply to any service that supports SSL encryption.
Ansible is an easy to use automation software that can update a server, configure tasks, manage daily server functions and deploys jobs as needed on a schedule of your choosing. It is usually administered from a single location or control server and uses SSH to connect to the remote servers. Because it employs SSH to connect, it is very secure and, there is no software to install on the servers being managed. It can be run from your desktop, laptop or other platforms to assist with automating the tedious tasks which every server owner faces.
Our previous article in this series focused on defining and fitting MPM to match your environment. Building off of our last tutorial we will be discussing specific details on how to adjust the previously mentioned Apache configuration directives on the various types of Liquid Web servers.
When a visitor accesses a website, a request is made to the web server for a specific kind of data. An example might be a home page of a site. Next, the web server locates that data and delivers it to the client who is requesting that data – basically back to the web browser.
In this example, the speed at which the home page loads can depend on a variety of factors. One of them could be how long it takes to find and deliver the data for that page. This is just one example.
This guide will walk you through the steps to create a Certificate Signing Request, (CSR for short.) SSL certificates are the industry-standard means of securing web traffic to and from your server, and the first step to getting your own SSL is to generate a CSR. This guide is written specifically for CentOS 7.
FTP (File Transfer Protocol) is one of the most popular methods to upload files to a server. There exist a wide array of FTP servers, such as vsftpd, you can use and FTP clients exist for every platform.
Essentially no matter what OS you use you can find an easy to use FTP client, so it makes for a great solution to transfer files. On CentOS based servers before you can connect via FTP you’ll have to setup an FTP server. Here we’re gonna setup vsftpd which is a great option since it has a focus on security and speed.
The EPEL repository is an additional package repository that provides easy access to install packages for commonly used software. This repo was created because Fedora contributors wanted to use Fedora packages they maintain on RHEL and other compatible distributions.
To put it simply the goal of this repo was to provide greater ease of access to software on Enterprise Linux compatible distributions.
What’s an ‘EPEL repository’?
The EPEL repository is managed by the EPEL group, which is a Special Interest Group within the Fedora Project. The ‘EPEL’ part is an abbreviation that stands for Extra Packages for Enterprise Linux. The EPEL group creates, maintains and manages a high quality set of additional packages. These packages may be software not included in the core repository, or sometimes updates which haven’t been provided yet. Continue reading “How to enable EPEL repository”→
