With a minute I had a virtual private server hosted at a unique IP with SSH access ready to go. Getting StartedĪfter hearing great things about them from colleagues, I chose Digital Ocean to host my VPS. load ( "passwords", "mysql" ) MoreĬhef has allowances for “roles” and “environments” in your deployment, but for setting up a single LAMP server I didn’t find these necessary. Mysql_pass = Chef :: EncryptedDataBagItem. They let you encrypt sensitive data and then retrieve it within recipes (or elsewhere): This is where Chef’s “data bags” come in. Speaking of secrets, you shouldn’t save these in plain text, of course (especially if sharing your recipe somewhere like Github). Use these for things like IP addresses, database names, or secret keys. How do nodes know which attributes can be customized for a recipe? Within a recipe (or within a cookbook to apply to all its recipes), you can specify and make use of default attributes that can be overridden later on.
use a different port) on different servers without having to copy-and-modify the recipe. Each one is a “node” in Chef, and nodes can have their own attributes which customize how recipes work.
# site-cookbooks/my-apache/recipes/default.rb include_recipe 'apache' override = 'my_config' NodesĬhef is capable of managing a single server or a herd of thousands. They might describe that a directory should exist and have certain permissions: They’re just Ruby files which make use of the Chef DSL. I used Solo since I’m managing only a single server.
APACHE APP CHEF UPDATE
With Chef Server, however, your computer pushes updates only to a centralized Chef server, and your individual servers check-in periodically with that central server and update themselves with the latest updated. With Chef Solo, your computer pushes updates directly to the server(s) you’re managing. ServerĬhef comes in two flavors: solo and server. Here are some of the primary concepts: Solo vs. Learning Chef means learning some new language. No more wondering why an app won’t run and it’s because the original sysadmin made an undocumented configuration change before leaving the company. It’s a simple idea, but the advantages are numerous: not only can you then set up a second server with close to zero effort, but perhaps more importantly, the server configuration is transparent (and ideally under version control).
APACHE APP CHEF CODE
The idea behind Chef is to describe in code how a server should be set up, and then let Chef do the installation and configuration. What follows is the blog post I wish I’d had available before jumping in.
APACHE APP CHEF HOW TO
Chef lived up to its reputation for being incredibly powerful, but it took me longer than I’d hoped to really understand how to use it. I chose to provision the server with Chef, which lets you describe how you’d like the server set up with a handy Ruby DSL and Chef takes care of the rest.
You can make your home automation with Raspberry Pi 4.Provisioning a LAMP Stack and WordPress with Chef, Part 1: Apache, MySQL, and PHPĪfter years of getting less and less while paying more and more for shared hosting, I finally decided to spin up my own (virtual) server to host a few WordPress sites. Raspberry Pi 4 is powerful hardware with low power. – Make your home automation with PHP CLI mode If you don’t know about Raspberry Pi 4 or IoT device. – Improve security for your Raspberry Pi with SSL Raspberry Pi 4 Workshop for you IoT with PHP CLI mode you can create your own Server and IoT at home easy to control your IoT device with the simple script from PHP.
