We’ll show you, how to set up SSH Keys on CentOS 7. SSH (Secure Socket Shell) is an open source, UNIX based, network protocol that provides users with a secure and encrypted way to login to remote computers, transfer files securely between the computers (SCP), command execution on remote servers, automate tasks between multiple servers on the network, and much more. SSH supports several authentication methods. In this tutorial we will configure SSH with public key authentication on CentOS 7 VPS, so instead of logging to your CentOS 7 VPS as usual using a username and password, you will be able to authenticate using a trusted SSH key which will increase the security of your server.
As you already know, Pelican is not a content management system like WordPress, it is a Python static blog generator – there is not database, nor a web interface. We use reStructuredText or Markdown to create the posts and pages and the entire content is flat-file based and managed by the CLI. This type of storage gives you the chance to manage the posts and if necessary to migrate them. As Scriptogram appears to be Pelican-based, you can move the files and posts (including permalinks) without changing them at all. Today we will show you how to install Pelican on CentOS 7 using Python 3. Let’s get started!

In this tutorial, we will show you how to install and set up Nginx on CentOS 7. Nginx is a high-performance, open-source software for web serving. It can be used as a proxy server for email (IMAP, POP3, and SMTP), as a reverse proxy and load balancer for HTTP, TCP, and UDP servers. It can also be used as a media streaming server. It features an event-driven design, which can make better use of today’s computer hardware than Apache’s process-driven design. Nginx is often seen as the “faster” alternative to other web servers such as Apache, being able to handle a higher load of concurrent connections while using less resources. Installing and configuring NGINX on CentOS 7, is fairly easy task and it shouldn’t take more then 10 minutes to finish it.

Today we will show you, How to reduce admin Ajax server load in WordPress. WordPress Heartbeat API was introduced in WordPress 3.6. The WordPress Heartbeat API uses wp-admin/admin-ajax.php to run AJAX calls from the browser. The purpose of this API is to improve user session management, auto saving, revision tracking. It sounds amazing, but it also has disadvantages that can also cause high CPU usage and crazy amounts of PHP processes. For example, if you leave your dashboard open it will keep sending POST requests on a regular interval, hence can cause the Heartbeat API to continually spawn PHP processes which uses CPU.
