![]() Old servers are no having the Apache Web server installed and up and running. A modified version of the commanders follows Yom dish y install http DE, followed by a double N percent, which means that I want to execute the second command only if the first command succeeded and a second command would be service HD GPD start. Now we need to add a command for installing the HD DPD service first on each machine you issued. Okay, things are starting to get more complex. This basically means that the Apache Web server needs to be installed first before attempting to start it. Now when the command runs, you noticed that a number of servers reported the following Enter service HD DPD Unrecognized service. As you can see, we have a mix of I P addresses and host names that should all be configured to run Apache. Let's have a look at the contents of the file. Http D on a number of machines that are listed in the file that a school Web servers the text. So I'm going to ask you, How many times did you have to issue a command like this? Of course, this code is used to start the Apache Web server. ![]() I assume that you are a lean ex administrator like me. The need for configuration management: OK alot of your run, I would like to welcome you to discourse. At the end, we'll automate destroying the environment once it's no longer needed.ġ. We'll automate all the prerequisites like security groups, the VPC and the like. We'll use Ansible to spin up and EC2 instance. The last project in this class demonstrates using Ansible in the cloud, namely on AWS. Again, we'll Ansible powerful modules and playbooks to automate this stack deployment so that you spin up a complete development environment with a single command. The term stands for MongoDB, ExpressJS, AngularJS, NodeJS. It's based on the newest web development technology: NodeJS. The MEAN stack is of no less popularity than the LAMP one. ![]() Additionally, we'll build a standard Laravel installation on top of our stack. We'll use Ansible to automate a LAMP stack deployment. It is very popular among developers worldwide. LAMP stands for Linux Apache MySQL and PHP. In this class, we'll work together on three projects: The class is project based so you'll get your hands dirty from the fist thirty minutes. In this class, I take you for an exciting journey to learn the ins and outs of this amazing product. It doesn't need any firewall rules other than the traditional SSH port 22 that is always enabled by default. However, it was able to prove itself in a very short time period, and effectively compete with other similar, more mature tools like Chef and Puppet.Īnsible will let you work from the comfort of your laptop, as you've always did before. Ansible is one of those tools.Īnsible is a relatively new kid in the block. Tools that will let you automate the repetitive stuff and let you focus on the more important stuff. Today, there are specialized tools for this purpose. Long gone are the days when you had to write shell scripts that installs runtime environments, create users, set permissions and deploys applications. In a fast-moving world like the one we live in now, when software applications need to be delivered in hours rather than months or even days, when developers, sysadmins, and testers all share the same mindset (DevOps), there has to be a better way of infrastructure configuration.
