Benchmarking is an important practice to analyse the overall performance of servers and identify bottlenecks as well as opportunities for improvement within those systems. In this guide, we’ll demonstrate how to benchmark the performance of a Redis server running on Ubuntu 18.04, using a few different tools and methods.
Fail2ban is a service that can be run on your server to dynamically block clients that repeatedly fail to authenticate correctly with your services . This can help mitigate the affect of brute force attacks and illegitimate users of your services. In this guide, we’ll demonstrate how to install and configure fail2ban to protect SSH on a Rocky Linux 9 server.
Prometheus is an open source monitoring system and time series database. In part 1 of this series, you will learn how to select and filter time series based on their dimensions, aggregate and transform time series, as well as how to do arithmetics between different metrics in Prometheus 1.3.1.
Terminalizer is a terminal recorder application that allows you to record your terminal session in real-time, and then play it back at a later date. It works in the same way as a desktop screen recorder, but instead runs in your terminal. In this tutorial, you will install Terminalizer, use it to record and play back terminal sessions, customize your recordings, and then export them to share online.
Apache’s mod_rewrite module lets you redirect URLs based on additional conditions, or rewrite URLs in a cleaner fashion, translating human-readable paths into code-friendly query string. In this tutorial, you’ll enable `mod_rewrite` and use `.htaccess` files to create a basic URL redirection, and then explore a couple of advanced use cases.
The Apache web server uses virtual hosts to manage multiple domains on a single instance. Similarly, PHP-FPM uses a daemon to manage multiple PHP versions on a single instance. Together, you can use Apache and PHP-FPM to host multiple PHP web-applications, each using a different version of PHP, all on the same server, and all at the same time.
O Redis é um datastore ou armazenamento de dados open-source de chave-valor na memória. O Redis lhe permite planejar uma sequência de comandos e executá-los um após o outro, um procedimento conhecido como transação. Cada transação é tratada como uma…
Let’s Encrypt is a Certificate Authority (CA) that provides an easy way to obtain and install free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. In this tutorial, you will use Certbot to obtain a free SSL certificate for Apache on Debian 9 and set up your certificate to renew automatically.
Consul is a flexible service discovery system that can be used to keep track of the existence and health of services available in your infrastructure. In previous guides, we discussed how to set up the base Consul system. In this guide, we will demonstrate how to secure the communications between different components using TLS to encrypt traffic.
In this tutorial, you will use Let’s Encrypt to obtain a free SSL certificate and use it with Nginx on CentOS 8. You will do this by using the Certbot Let’s Encrypt client. You will also set up automatic renewal of your SSL certificate with a cron job.
