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
Start PostgreSQL on Clients in the dbservers and adminservers Groups
services.ymlfurther 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
