Ansible:如何通过 Ansible 获取服务状态？

Question

我想通过 Ansible 获取诸如 redis-server 之类的服务运行状态。

我知道如何使用 Ansible 服务模块来停止或启动系统服务。但如何获取当前的服务状态呢？

Answer 1

您还可以使用service_facts模块。

使用示例:

- name: collect facts about system services
  service_facts:
  register: services_state

- name: Debug
  debug:
    var: services_state

示例输出:

TASK [Debug] ******************************************************
ok: [local] => {
    "services_state": {
        "ansible_facts": {
            "services": {
                "cloud-init-local.service": {
                    "name": "cloud-init-local.service",
                    "source": "systemd",
                    "state": "stopped"
                },
                "firewalld.service": {
                    "name": "firewalld.service",
                    "source": "systemd",
                    "state": "stopped"
                }
            }
        }
    }
}
