软件lamp目录结构： files:存文件的，ansible默认就会到这里目录去找文件，对应task里面的copy模块 tasks：存放tasks的 handlers：存放handlers templates：存放模板，对应task里面的模块template vars：这里面定义的变量，只对当前role有作用 meta：定义role和role直接的依赖关系。 [[email protected]_2 ~]# tree /root/lamp/ /root/lamp/ ├── hosts ├── roles │ ├── apache │ ├── handlers │ │ └── main.yml │ ├── tasks │ │ └── main.yml │ └── templates │ └── file.j2 └── wq.yml
lamp/hosts 文件内容:
[[email protected]_2 ~]# cat /root/lamp/hosts [test] 192.168.1.211 192.168.1.212 192.168.1.213
lamp/wq.yml 文件内容:
[[email protected]_2 ~]# cat /root/lamp/wq.yml
---
- name: install httpd
hosts: all

#- mysql
#- {role: apache,tags:{‘delete_httpd‘}}
- name: install mysql
hosts: all
roles:
- mysql
lamp/roles/apache/tasks/main.yml 文件内容:
[[email protected]_2 ~]# cat /root/lamp/roles/apache/tasks/main.yml --- - name: install httpd yum: name=httpd state=present notify: - restart httpd - restart iptables #- include: delete_httpd.yml #会调用、roles/apache/handlers/main.yml文件里 #对应name为restart httpd和restart iptables的相应命令并执行， #若之前apache服务已安装，再次执行，notify无法c触发
lamp/roles/apache/handlers/main.yml 文件内容:
[[email protected]_2 ~]# cat /root/lamp/roles/apache/handlers/main.yml --- - name: restart httpd service: name=httpd state=restarted - name: restart iptables service: name=iptables state=restarted
