I’ve first heard of Page Speed last year for Apache. I was really waiting a stable version for Nginx and it’s now done. A few days ago, Nicolargo made a post regarding it and that’s what motivated me to go ahead on Page Speed.
PageSpeed speeds up your site and reduces page load time. This open-source webserver module automatically applies web performance best practices to pages and associated assets (CSS, JavaScript, images) without requiring that you modify your existing content or workflow.
I discovered Dotdeb a few months ago and decided to make a quick documentation to install the repository. But before, here is the official explaination of what is the repository made for :
Dotdeb is a repository containing packages to turn your Debian boxes into powerful, stable and up-to-date LAMP servers :
Nginx PHP 5.4 and 5.3, useful PHP extensions : APC, imagick, Pinba, xcache, Xdebug, XHprof… MySQL 5.
I already talked about nftables and it has now been implemented in the 3.13 kernel !
For those who never heard of that, it’s a kernel built in replacement of iptables. All features are not there yet but should be implemented in 3.15.
If you like Packet Filter, you’ll be happy. If you’re not sure of the advantages of it, simply read that short comparison and you’ll be convinced : https://home.
I’ve recently updated some of my tutorials :
Optimizing Hard Drive performances : I’ve updated SSD subject Luks : added more information on how auto mount automatically at boot a crypted partition. Xtrabackup : corrected a non working command LXC : modified containers files to avoid boot issues APT-Pinning : Added the command to install a package from a designed repository Sed : forgotten to add -i option which is so important Vagrant : Added an example to the quick tutorial
Varnish is a real powerful cache solution for web servers. He is unfortunately not able to do it over SSL. Anyway, there is a solution by offloading it with Nginx. Here is a schema to get a better understanding :
Nginx decrypt SSL, pass it in clear to Varnish. If Varnish got it, replies to Nginx which crypt back data to send to user.
I’ve made a full documentation to get it working well, follow the link.
In addition of object storage, Ceph is able to provide block devices. Ceph’s RADOS Block Device (RBD) provides access to block device images that are striped and replicated across the entire storage cluster.
For example this is used to store Virtual Machines on OpenStack. With that solution, you’ve got a real fault tolerance system for your VM and distributed.
The RBD part is an easy task when you’ve already setup a Ceph cluster.
CloudFlare is a Free solution to load your website faster and add security. I’ve tested it 2 days ago, that’s why you may experienced issues in accessing the blog and wiki.
I had issues on WordPress, so I need to correct some problems relating images (http/https) as the Free version of CloudFlare doesn’t support SSL. That’s why I’ve roll back for the moment.
I have other kind of modifications to make on WordPress before it works as it should.
