MariaDB is totally open source version of MySQL It works just like MySQL and is compatible with MySQL setups Fedora and Red Hat/CentOS is moving to use MariaDB from Fedora 19/RHEL 7/CentOS 7 versions This is guide,  howto install or upgrade MariaDB 10.1.20 [stable] (10.0.28 [stable] or 10.2.2 [beta] or 5.5.53 [stable]) on Fedora 25/24/23, CentOS 7.3/6.8/5.11 and Red Hat (RHEL) 7.3/6.8/5.11 . Installing MariaDB is almost same process than install MySQL. Note: If you are moving from MySQL, then make sure that you backup (dump and copy) your database and configs. And if upgrading from earlier versions, then remember run mysql_upgrade command. And if you uninstall MySQL, then remember restore /etc/my.cnf after installation, like: Bash mv -vi /etc/my.cnf.rpmsave /etc/my.cnf ...

Introduction LDAP stands for Lightweight Directory Access Protocol  and, as the name suggests, it’s a standard protocol for accessing and maintaining distributed directory information services over an IP network. In this tutorial, we’ll install a LDAP server on Centos 7 using 389 Directory Server. Getting started First of all,  configure FQDN in /etc/hosts . In that file, put the server’s fully qualified domain name. 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 X.X.X.X yoursever.hostname.lan server Of course, substitue the last line in this example with your server’s informations. Configure firewall As you may know, we need to allow LDAP server’s default ports via firewall in order to access it from a remote system. So: firewall-cmd --permanent --add-port=389/tcp firewall-cmd --permanent --add-port=636/tcp firewall-cmd --permanent --add-port=9830/tcp N...

Introduction It was September when, with a  post on its blog , Google announced that starting from Chrome 56, its browser will mark non-secure pages containing password and credit card input fields as  Not Secure  in the URL bar. It’s important to note that we are talking about  all HTTP pages  collecting users’ “critical” data. This move is part of a long-term plan to mark all HTTP sites as non-secure. So, if you own (or manage) a web server, you need to make the right move:this article this will explain just what that means. Why HTTPS? The first question is: why is Google doing this? What are the concerns around HTTP, and why, today, is it a good choice to secure connections? Of course, everybody knows that secure is better then insecure; but in this case, the big problem with HTTP is that it lacks a system for protecting communications between clients and servers. This exposes data to different kinds of attacks, for instance, th...

To build a dynamic web application, you need what has been coined a “stack” - which is developer lingo for an integrated set of software that has all of the components your application needs. Most stacks have the same types of components and differ mainly in which pieces of software they use for those components. For example, we’ll look at LAMP (which this article covers): LAMP Software: Linux (e.g. CentOS), Apache, MySQL, PHP If you're astute, maybe you noticed that LAMP is just an acronym for the software the stack uses. In this guide, we'll walk you through installing all of these components (except for Linux, which is already installed as your OS when you create the server). Install Apache Before you begin any installation, make sure that your software is up to date: # sudo yum update Install Apache: # sudo yum install httpd Start Apache: # sudo systemctl start httpd.service Set Apache to start on server b...

This guide will show you how to enable SSL to secure websites served through Apache on CentOS or Fedora. Before You Begin This guide assumes that you are running Apache2 on CentOS or Fedora. Prior to starting this guide, ensure that the following steps have been taken on your Linode: Familiarize yourself with our Getting Started guide and complete the steps for setting your hostname and timezone. In order to configure your Apache server to function with SSL, you will need to ensure that the Apache mod_ssl module is installed on your system. You can do so by running the following command:           # yum install mod_ss Configure Apache to use the SSL Certificate Edit the virtual host entries in the /etc/httpd/conf.d/ssl.conf file to include the certificate files and virtual host information that should be used by each domain. For each virtual host, replicate the configuration shown below. Replace each mention of example.com with ...

Apache is an open-source web server that can be configured to serve a single or multiple websites using the same Linode. This guide explains how to install and configure the Apache web server on CentOS 7. This guide is written for a root user. Replace each instance of example.com in this guide with your site’s domain name.  Before You Begin Ensure that you have followed the Getting Started and Securing Your Server guides, and the hostname is set. To check your hostname run: # hostname # hostname -f The first command should show your short hostname, and the second should show your Fully Qualified Domain Name (FQDN). Update your system: # sudo su - # yum update Install and Configure Apache # yum install httpd Modify httpd.conf with your document root directory to point Apache to your site’s files. Add the <IfModule prefork.c> section below to adjust the resource use settings. The settings shown below are a good starting point for a 2GB: Before c...
