A Vagrant profile that installs a LEMP stack split into two Ubuntu 16.04 (Xenial) virtual machines using VirtualBox for virtualization and Ansible for provisioning.
- Machine 1 (
db1): MySQL 5.7 - Machine 2 (
web1): Nginx, PHP 7.1 and PHP FPM
Requirements:
- VirtualBox
- VirtualBox Guest Additions
- Vagrant >= 1.8
- Vagrand Host Manager*
- Ansible >= 1.6
* The Vagrand Host Manager plugin is used to ease communication between the hosts defined in the Vagrantfile.
To install the necessary Ansible roles, change directory into the folder containing the Vagrantfile and issue the following command:
$ ansible-galaxy install -r ansible-requirements.ymlStart all Vagrant VMs with the following command:
$ vagrant upTo SSH into a VM, web1 for example, use this command:
$ vagrant ssh web1You can modify your host machine's hosts file (typically /etc/hosts on Mac and Linux) by appending the following line to it:
192.168.34.90 web-app.local
(web-app.local is the hostname configured by default in the Vagrantfile.)
That will allow you to visit http://web-app.local/index.php in a browser and see the web application in action (the web application, in this case, is a single PHP file, index.php).
To re-provision the machines after updates to the Ansible files, you can use the provision command. For example, to re-provision the web1 machine you can use:
$ vagrant web1 provision --provision-with ansibleThe credentials for the web-app database (inside the db1 VM) are:
- username:
web-app - password:
web-app
The index.php file (inside the web-app directory) contains a simple example of how to access that database from the PHP application.
The database credentials are exposed as environment variables in the web VM (web1), so your PHP application can make use of them instead of relying on hard-coded values; frameworks like Symfony allow you to use those variables from inside their configuration files.
