1. Challenge

   Start httpd on the Clients in the webserver Group

   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
   

2. Challenge

   Start PostgreSQL on Clients in the dbservers and adminservers Groups

   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
