Apache installed with Ansible - quick notes

Install Apache 2 web server automatically. Serves a web site on the front page of http://localhost. Pages can be edited as a normal user.

Simplified Ansible role. An example of package-file-server pattern. Just notes, no tutorial.

Using these short notes require a working Ansible configuration - Hello Ansible.

Package-file-service pattern

Daemons, like Apache2 web server, are somewhat similar. They are configured with package-file-service pattern. Install the daemon, change configuration by editing files, start it.

• package - sudo apt-get install apache2
• files - sudoedit /etc/apache2/...
• service - sudo systemctl restart apache2

Changes to configuration files only take effect after you kick the daemon. Thus, file in tasks/main.yml notify the handler "restart apache2".
