Get NGINX status with an Ansible playbook-CodePudding

I try to install NGINX from an Ansible playbook.

Currently I use this playbook to install it:

---
- hosts: all
  gather_facts: true
  become: true
  become_user: root
  tasks:
    - apt:
        name: nginx
      when: ansible_os_family == "Debian"

And it works:

Identity added: /runner/artifacts/46/ssh_key_data (root@debian)
SSH password: 
PLAY [all] *********************************************************************
TASK [Gathering Facts] *********************************************************
ok: [192.168.1.75]
TASK [apt] *********************************************************************
changed: [192.168.1.75]
PLAY RECAP *********************************************************************
192.168.1.75               : ok=2    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

But I would like to see the state of the NGINX service at the end of my playbook, like that:

Identity added: /runner/artifacts/46/ssh_key_data (root@debian)
SSH password: 
PLAY [all] *********************************************************************
TASK [Gathering Facts] *********************************************************
ok: [192.168.1.75]
TASK [apt] *********************************************************************
changed: [192.168.1.75]
TASK [Verify nginx state] *********************************************************************

Or something similar.
How can this be achieved?

Regarding your requirement

I would like to see the state of the nginx service a the end of my playbook

it is recommended just to use the systemd module.

- name: Make sure 'nginx' is started
  systemd:
    name: nginx
    state: started
    enabled: yes
  register: result

- name: Show result
  debug:
    msg: "{{ result }}"

For later check of specific services you can use service_facts.

- name: Gathering service facts
  service_facts:

- name: Get facts
  debug:
    msg:
      - "{{ ansible_facts.services['nginx'].status }}"

CodePudding user response：

you could get that detail from the sudo command here

  - name: check for service status
    shell: sudo service nginx status
    ignore_errors: true
    register: nginxstatus

  - name: Show service service status
    debug:
      msg: 'nginxstatus exists.' 
    when: nginxstatus.rc | int == 0

CodePudding user response：

or even better

- name: Check status of the nginx server
  shell: 'systemctl nginx status'
  register: command_output

- debug:
         var: command_output.stdout_lines
