Anaconda is a free and open-source distribution of the Python and R programming languages. It is used for scientific computing, machine learning, and data science that involves heavy calculations and predictive analysis. Anaconda Python offers over 1400 data packages, both free and paid.
In this tutorial, we will explain how to install the Anaconda Python Distribution on Ubuntu 18.04.
After installing or setting up a new Ubuntu 18.04 server, you will need to perform some basic steps to increase the server’s security, performance and reliability.
In this tutorial, we will show you some basic configuration steps you should perform after installing a new Ubuntu 18.04 server.
MariaDB is free, open-source, and one of the most popular database servers in the world. It is a community-developed fork of the very popular MySQL database management system. MariaDB provides support for PHP and uses a standard and popular querying language. MariaDB comes with a wide range of storage engines and several optimizations that can be used to improve the database performance.
In this tutorial, we will show you how to manage databases in MariaDB on Ubuntu 18.04.
Lighttpd is a free, open-source, and high-performance web server designed for speed-critical environments. It is lightweight, secure, fast, and consumes very few resources compared to other web servers. Lighttpd also supports FastCGI, CGI, Output-Compression, Auth and URL-Rewriting, which makes it the perfect web server. Lighttpd can handle up to 10000 connections in parallel on a single server.
If you are looking for a fast, efficient, and secure web server, then Lighttpd is the best choice for you.
ModSecurity, also known as Modsec, is a free and open-source web application firewall for Apache webserver. ModSecurity is an Apache module that helps you to protect your web server from different types of attacks including SQL injection, XSS, trojans, bots, session capture/hijacking, and many more. ModSecurity provides powerful rule sets with real-time web monitoring, logging, and access control.
In this tutorial, we will show you how to install and configure Mod Security with Apache on Ubuntu 18.04.
SSH stands for “Secure Shell” and is an encrypted protocol used to log in and manage a remote server. SSH also supports various authentication mechanisms. SSH uses password-based authentication and public key-based authentication for a secure connection between a client and a server. SSH key-based authentication is more secure than password-based authentication because keys are very hard to guess or crack using currently available computing power.
In this tutorial, we will show you how to set up SSH key-based authentication on an Ubuntu 18.04 server.
Protecting your web server against different kinds of attacks is a crucial responsibility for any system administrator. ModEvasive is an Apache web server module that helps you to protect your web server in the event of DoS, DDoS, and brute-force attacks. These types of attacks cause the server to run out of memory, crashing your website.
Database clustering is the process of combining multiple servers by connecting them to a single database. Clustering improves your database’s availability by distributing load to different servers. If any server fails, others are quickly available to continue serving.
MariaDB Galera is a multi-master clustering solution that allows you to read and write to any node in the cluster. With MariaDB Galera, a change made to any one node is replicated to all nodes. MariaDB Galera supports the XtraDB/InnoDB storage engines and is available on Linux only.
Accurate time synchronization over the Internet is a crucial point for any system administrator. If your server time is not synchronized with the correct time zone, you can face data corruption or other issues. NTP, which stands for Network Time Protocol, is a TCP/IP protocol used for synchronizing time over a network. By default, Ubuntu 18.04 uses systemd’s timesyncd service for time synchronization.
In this tutorial, we will show you how you can check whether time synchronization is working on your Ubuntu 18.04 server.
MariaDB is a free, open-source relational database management system, and is one of the most popular options. Replication is the process of copying data from one master database server to another slave database server. In the master-slave topology, one server acts as the master and other servers act as slaves. In master-slave replication, data is replicated one-way only. If you change the data on the slave server, it will not be replicated to the master server. If the master server goes down, you can still recover your data from the slave server.
