I'm in the process of setting up a webserver and I was wondering what the best practice method of updating the website it contains would be. Any series of changes that are due to go to a production machine are put together in a patch which consists of any files/scripts needed and a script (a shell script usually for a Unix-a-like environment, a batch file or vbs script or powershell script under Windows) that applies those files/scripts appropriately.I'm aware that I should have some sort of 'test' server running in parallel so that changes can be tried their first before they go live. Mediawiki and Wordpress both have PHP and My SQL backends. We then take the relevant VM, update its database(s) from a copy of production if the VM's copy is getting too out-of-date (remembering to re-run the relevant SQL scripts for wiping or randomising sensitive data) and take a snapshot of it in this state (snapshots are supported by virtualbox and most vmware products including the free "vmware server", and probably most other virtualisation solutions too). We use a series of virtual machines, at least one for each live client server, that is kept in sync with the live machines (aside from some of the data being munged so we are not working with personally identifying or otherwise sensitive information). The more detail you can provide, the more accurate options people can offer.by using the auto flag RVM will know to update the user configuration files to the best known way of sourcing RVM.In early days RVM was developed only on master branch, versions were released to RVM server and when version was bug free the latest file was updated to point to it.
Capistrano is a program that allows developers to automate the deployment process using a Ruby based script.
Let’s begin by establishing what makes deploying updates for web applications challenging.
A deployment can be thought of as a form of cache invalidation, something that is commonly labeled one of the two hardest problems in Computer Science.
When updating very old versions head should be used and can be followed by stable.
