使用Ansibleplaybook獲取NGINX狀態

我嘗試從 Ansible playbook 安裝 NGINX。

目前我使用這個劇本來安裝它：

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

它有效：

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  

但我想在我的劇本末尾看到 NGINX 服務的狀態，如下所示：

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] *********************************************************************

或類似的東西。
如何做到這一點？

關于您的要求

我想在nginx我的劇本結束時看到服務的狀態

建議只使用該systemd模塊。

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

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

為了以后檢查您可以使用的特定服務service_facts。

- name: Gathering service facts
  service_facts:

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

uj5u.com熱心網友回復：

您可以從此處的 sudo 命令獲取該詳細資訊

  - 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

uj5u.com熱心網友回復：

甚至更好

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

- debug:
         var: command_output.stdout_lines

標籤：nginx 可靠的
