role综合测试

1、模拟安装httpd

 1 [root@linux-node1 ansible]# tree roles/
 2 roles/
 3 ├── app
 4 │   ├── files
 5 │   │   └── vhosts.conf
 6 │   ├── handlers
 7 │   │   └── main.yml
 8 │   ├── tasks
 9 │   │   ├── copyfile.yml
10 │   │   ├── group.yml
11 │   │   ├── main.yml
12 │   │   ├── start.yml
13 │   │   ├── templ.yml
14 │   │   ├── user.yml
15 │   │   └── yum.yml
16 │   ├── templates
17 │   │   └── httpd.conf.j2
18 │   └── vars
19 │       └── main.yml

tree目录层级

 1 [root@linux-node1 tasks]# cat main.yml 
 2 - include: group.yml
 3 - include: user.yml
 4 - include: yum.yml
 5 - include: templ.yml
 6 - include: copyfile.yml
 7 - include: start.yml
 8 [root@linux-node1 tasks]# cat group.yml 
 9 - name: create group
10   group: name=app
11 [root@linux-node1 tasks]# cat user.yml 
12 - name: create user
13   user: name=app group=app
14 [root@linux-node1 tasks]# cat yum.yml 
15 - name: install package
16   yum: name=httpd
17 [root@linux-node1 tasks]# cat templ.yml 
18 - name: copy conf
19   template: src=httpd.conf.j2 dest=/etc/httpd/conf/httpd.conf
20   notify: restart service
21 
22 [root@linux-node1 tasks]# cat copyfile.yml 
23 - name: copy cofig
24   copy: src=vhosts.conf dest=/etc/httpd/conf.d/ owner=app
25 [root@linux-node1 tasks]# cat start.yml 
26 - name: start service
27   service: name=httpd state=started enabled=yes

tasks

1 #这里碰到一个坑，如果把main.yml 给成其他名字报错如下
2 ERROR! The requested handler 'restart service' was not found in either the main handlers list nor in the listening handlers list
3 #抗我了2个小时尴尬
4 [root@linux-node1 app]# cat handlers/main.yml 
5 - name: restart service
6   service: name=httpd state=restarted

handlers/main.yml

[root@linux-node1 ansible]# cat roles/app/vars/main.yml 
username: app
groupname: app

[root@linux-node1 ansible]# cat app_role.yml 
- hosts: date
  remote_user: root

  roles:
    - app

templates、files为测试目录自己改吧改吧，测试成功哈哈
