Varnish is a web application accelerator that provides an easy speed increase to most web applications and Drupal is no exception. It works by creating a reverse proxy service that sits in front of your web server and caches traffic that comes through it. When the page is requested, Varnish forwards the request to the web server to complete the request, the response that comes back from the web server is then cached by Varnish. This means that the next request to the same page is served by Varnish and not the web server, which results in a large speed increase.
Basic HTTP authentication is a simple authentication mechanism that is used to prevent access to an site or directory on a server. It is by no means the most secure authentication mechanism but it is commonly used on staging sites in order to prevent unwanted access. This is a good way of preventing search engine bots from spidering the staging site, which is undesirable as it can cause staging site pages appearing in search engines results.
Many systems and applications require certain access to certain ports and protocols. When installing these systems using Ansible it is necessary to also open up the needed ports so that the systems can function correctly. As there is no iptables module in Ansible the shell command is needed to add the iptables rules.
As an example, here is a task that adds a iptables rule to allow Apache to communicate on port 80.
When you first install a Munin node it will try to install as many plugins as it can so that it can report on different things. For example, if you have a Varnish server running then Munin will detect this and enable the plugins so that it can report on the activity of Varnish. Once you have started getting data through to your Munin server then you can turn on plugins on the nodes to get more data.
Phing is an awesome tool for automating things and I use it more and more for automating all kinds of different tasks. One of the tasks that I don't tend to do all that much is setting up a new local virtual host for Apache on my development machines. I know how to do it, but there is always something I forget to do, or a convention that I don't follow which means that I have to repeat myself at a later date to fix something I have missed.
I recently built a Drupal site on an Apache server sertup and everything seemed fine until someone running IE8 tried to download a .docx file. For some reason IE8 insisted that this file was a .zip file and would open it as such, causing a bit of confusion as to what the problem was. I assumed that this was due to the mime type of the file not being set properly, but I decided to do a quick search to see if I could find anything to corroborate this. I thought it might be something odd that IE8 was doing as everything else was downloading the file perfectly.
Use the following rules in your Apache configuration (or your .htaccess file) to redirect all traffic from one domain to another. This also keeps the query string in place so that the user isn't just dumped to the homepage.
I was recently setting up a localhost environment with Ubuntu 11 and after adding all of my needed VirtualVost directives I found that I could start/restart the server but that I found the following error when trying to start the server.
Following on from the post about starting and stopping MySQL using .bat files I decided to add commands to these files that also controlled Apache in the same way. This turned out to be a lot easier than trying to start and stop MySQL as the command line commands for httpd executable worked very well in .bat files.
So, to start Apache use the following line.
