Ansible Service模块手册

Posted 2021-10-18 青衫解衣

Service模块

启动nginx服务:

ansible all -m service -a "name=nginx state=started"

关闭nginx服务:

ansible all -m service -a "name=nginx state=stopped"

设置nginx开机自启动:

ansible all -m service -a "name=\'nginx\' enabled=yes"

 

重启nginx服务，设置开机自启动：

ansible all -m service -a \'name=nginx state=restarted enabled=yes\'

Playbook service模块写法:

启动nginx服务，并设置开机自启动。

[root@master ~]# cat svc.yml 
- hosts: all
  tasks:
  - name: Enable service httpd, and not touch the state
    service:
      name: nginx
      state: started
      enabled: yes

 

下面这个参数不会使用，本来想尝试reids和mongo的，结果发现不行，哪位大佬知道咋用》评论区回复。

- name: Start service foo, based on running process /usr/bin/foo

  service:

    name: foo

    pattern: /usr/bin/foo

    state: started

 

Service模块中 notify、 handlers触发器的使用:

[root@master ~]# cat svc2.yml 
---
- hosts: all 
  remote_user: root 
  vars:
    - pkg: nginx
  tasks:
    - name: "install nginx package."
      yum: name={{ pkg }}  state=installed
    - name: "copy httpd configure file to remote host."
      copy: content="hello mew" dest=/usr/share/nginx/index.html
      notify: restart nginx     # 当这个任务执行状态发生改变时，触发handlers执行.
    - name: "boot httpd service."
      service: name=nginx state=started
  handlers:      # handlers与tasks是同一级别
    - name: restart nginx
      service: name=nginx state=restarted
