Using Ansible Modules to Manage Services in Your Environment

Create and edit services.yml, and add a section to start httpd. The block will look like this:

---
- name: Start httpd
  hosts: webservers
  become: yes

  tasks:
  - service:
     name: httpd
     state: started
     enabled: yes

Edit services.yml further and add a section to start PostgreSQL. Because the services need to start asynchronously, we have to use the systemd module:

- name: Start postgresql
  hosts: dbservers:admins
  become: yes

  tasks:
  - systemd:
     name: postgresql
     state: started
     no_block: yes
