mod_geoip2 Apache module

25/05/2023 Aucun commentaire

The mod_geoip2 module embeds GeoIP database lookups into the Apache web server. It is only capable of looking up the IP of a client that connects to the web server, as opposed to looking up arbitrary addresses.

This module works with Apache 2. Please use mod_geoip with Apache 1.

Installation

You may download the latest release of mod_geoip2 or get the latest development version from GitHub. See the included INSTALL file in the tarball for installation details.

Overview

The mod_geoip2 module uses the libGeoIP library to look up geolocation information for a client as part of the http request process. This module is free software, and is licensed under the Apache license.

To compile and install this module, you must first install libGeoIP 1.4.3 or newer.

The mod_geoip2 module takes effect either during request header parsing phase or the post read request phase, depending on whether it is configured for server-wide use or for a specific location/directory.

When enabled, the module looks at the incoming IP address and sets some variables which provide geolocation information for that IP. The variables it set depend on the specific GeoIP database being used (Country, City, ISP, etc.). These variables can be set in either the request notes table, the environment or both depending on the server configuration.

My file in the /etc/apache2/sites-available/mysite.localhost.conf is as follows :

        ServerName mysite.localhost

        DocumentRoot /var/www/mysite

Rediriger un nom de domaine vers un sous-répertoire

Quand votre nom de domaine pointe vers un hébergement mutualisé, vous n’avez, la plupart du temps, pas le droit de modifier les VirtualHost du serveur Apache.

Pour pallier ce manque, une redirection s’impose mais par un autre biais: l’utilisation de l’URL Rewrting. Lire la suite…

How To Use Apache JMeter To Perform Load Testing on a Web Server

03/05/2023 Comments off

Introduction

In this tutorial, we will go over how to use Apache JMeter to perform basic load and stress testing on your web application environment. We will show you how to use the graphical user interface to build a test plan and to run tests against a web server.

JMeter is an open source desktop Java application that is designed to load test and measure performance. It can be used to simulate loads of various scenarios and output performance data in several ways, including CSV and XML files, and graphs. Because it is 100% Java, it is available on every OS that supports Java 6 or later.

 

Prerequisites

In order to follow this tutorial, you will need to have a computer that you can run JMeter on, and a web server to load test against. Do not run these tests against your production servers unless you know they can handle the load, or you may negatively impact your server’s performance.

You may adapt the tests in this tutorial to any of your own web applications. The web server that we are testing against as an example is a 1 CPU / 512 MB VPS running WordPress on a LEMP Stack, in the NYC2 DigitalOcean Datacenter. The JMeter computer is running in the DigitalOcean office in NYC (which is related to the latency of our tests).

Please note that the JMeter test results can be skewed by a variety of factors, including the system resources (CPU and RAM) available to JMeter and the network between JMeter and the web server being tested. The size of the load that JMeter can generate without skewing the results can be increased by running the tests in the non-graphical mode or by distributing the load generation to multiple JMeter servers.  Lire la suite…

How To Install and Secure phpMyAdmin on Ubuntu 16.04

01/05/2023 Comments off

Introduction

While many users need the functionality of a database management system like MySQL, they may not feel comfortable interacting with the system solely from the MySQL prompt.

phpMyAdmin was created so that users can interact with MySQL through a web interface. In this guide, we’ll discuss how to install and secure phpMyAdmin so that you can safely use it to manage your databases from an Ubuntu 16.04 system. 

Prerequisites

Before you get started with this guide, you need to have some basic steps completed.

First, we’ll assume that you are using a non-root user with sudo privileges, as described in steps 1-4 in the initial server setup of Ubuntu 16.04.

We’re also going to assume that you’ve completed a LAMP (Linux, Apache, MySQL, and PHP) installation on your Ubuntu 16.04 server. If this is not completed yet, you can follow this guide on installing a LAMP stack on Ubuntu 16.04.

Finally, there are important security considerations when using software like phpMyAdmin, since it:

  • Communicates directly with your MySQL installation
  • Handles authentication using MySQL credentials
  • Executes and returns results for arbitrary SQL queries

For these reasons, and because it is a widely-deployed PHP application which is frequently targeted for attack, you should never run phpMyAdmin on remote systems over a plain HTTP connection. If you do not have an existing domain configured with an SSL/TLS certificate, you can follow this guide on securing Apache with Let’s Encrypt on Ubuntu 16.04.

Once you are finished with these steps, you’re ready to get started with this guide.
