Running multiple web applications on a single Ubuntu server is a smart way to save costs and simplify management — especially if you’re combining apps built with different tech stacks, like PHP and Java.
In this post, we’ll walk you through running a PHP web app and a Java-based Metabase instance on the same Ubuntu server, using Apache as the front-facing web server and SSL secured via your own certificate or Let’s Encrypt.
Recently in Ubuntu which I use for my hosting operating system of choice I needed to bulk change permissions on a bunch of folders and files. I needed to set permissions on folders within a WordPress installation to 755 and all files in theme, plugin and asset directories to 644.
We are all trying to increase our sites speed and give our users a better experience and one often overlooked method is to leverage browser caching.
For anyone who doesn’t know exactly what we are trying to do here, I’ll try and explain. Browser caching stores elements of internet sites for an amount of your time so as to form them load quicker. For instance, if you look at 10 pages on a website and it has the same background image, logo, social media icons and so on, we can store these in the browser in order that they don’t keep being downloaded.
