The issue is only at the website home page's PHP script has the download behaviour but the rest of the website pages' PHP script run normally. In this article will show two solutions. This issue is very hard to debug because there are no helpful logs that will give hint on solving this issue. Actually, I was debugging a "Permission denied" issue and the fixes I tried to apply to this resulted to our main topic issue. The web server setup: Nginx as reverse proxy to Apache and under a web hosting control panel.

GeoIPLookup is available in Unix system as command line tool to look up for geolocation using IP address or hostname. It uses the GeoIP database/library usually found in:

The web browsers by default limits number of concurrent connections for each host. When that limit exceeds, the resources (like CSS, images, etc.) will remain in queue waiting to be downloaded until the prior downloads are completed. This results slow page load times user experience. One solution to reduce page load time is by domain sharding. This technique splits the resources download across multiple sub-domains (eg. static1.webfoobar.com, static2.webfoobar.com) resulting an increase in simultaneous connections.

In this article, we will take a look on how to exempt from banning visitors from a specific country using Fail2ban and geoip. It is assumed that Fail2ban is already installed and configured in your server.

Lets install first the geoip:

  
yum install geoip
  

Create Fail2ban action script:

  
vi /etc/fail2ban/action.d/geohostsdeny.conf
  

Copy the following script:

With GoAccess, we can monitor/analyze almost any logs and view them nicely in a terminal on the fly and it can also output as HTML, json or csv.

Most GoAccess examples we see out there are for web access logs. What if we need to analyze error logs for attack logs like:

We know that Vagrant is a tool for building complete development environments. It allows us to imitate the setup of a server on our local machine which can be easily reproduced on any system.

This article will show three useful routines for Vagrant: saving an existing Vagrant box setup, removing old/unused Vagrant box and restoring saved vagrant box. It is assumed that you are using Windows as host machine's OS and Cygwin command line interface. Throughout this article, we will be using centos7drupal name for our Vagrant box.

Munin has large collection of plugins included in core plus its contrib plugins. These plugins are scripts are executed by munin-node and reports back different statistics that Munin master monitors. This article will help understand about Munin plugins, this is a continuation of Setup Munin on CentOS 7 with nginx.

The Munin's generated web pages are very old fashioned and dull. Its design uses tables with small text and too much spaces. This guide will show how to change the Munin's template and should be continuation of Setup Munin on CentOS 7 with nginx. There will be two alternative Munin 2.x templates will be shown here:

1. Munin Dynamic Template

This alternative template uses jQuery and Twitter Bootstrap for Munin 1.x and 2.x versions that enhanced user experience and improve web pages' appearance. The following are the steps to setup this template:
