In this tutorial called create MySQL slave by cloning we’ll try to guide you through a very detailed but in the same time simple process to create a MySQL slave, also known as MySQL replica, by using a fresh backup taken from an existing MySQL server referred here as MySQL master server. Assuming that our master database is 11TB large we’ll have to copy its data content from US, where the master server is located to another server located in a UK data centre, not quite an easy task with this amount of data or without using a costly commercial […]

It’s well known that is impossible to create partitions larger than 2TB in Linux using the default utility fdisk that comes with most of Linux distros, at least for now. In this short tutorial we’ll learn how to create larger than 2TB partitions using parted utility instead of fdisk on CentOS Linux. Assuming that we have to add three new disks to a new fictive server called mydbhost that will be used for a MySQL service for example, being master, slave, standalone it doesn’t matter, all that we care is the partitioning bit.

Before we start our little journey we should be clear about one thing, all SSH Keys consists of two parts, a Private Key and a Public Key. In this article we’ll generate both these keys and we’ll learn the importance but also the difference between these two.

Category: General | Published: 08/02/2018 | Updated: 05/11/2018In this example we will explain how to generate CSR in Linux using shell prompt or terminal window. A CSR is mostly required when you want to secure for example a website or a connection between one or more services that requires a secure connection. Any SSL issuer will always ask you to generate and present a CSR. We’ve chose CentOS for this Certificate Signing Request example as our main operating system. Required packages First step is to make sure that we have openssl and openssl-devel packages installed and updated in order to generate our very first CSR. The package manager […]
