调用多个角色

1、在模拟一个http的role

 1 [root@linux-node1 ansible]# cat httpd_role.yml 
 2 - hosts: date
 3   remote_user: root
 4 
 5   roles:
 6     - httpd
 7 [root@linux-node1 tasks]# cat main.yml 
 8 - include: user.yml
 9 - include: copyfile.yml
10 [root@linux-node1 tasks]# cat copyfile.yml 
11 - name: copy files
12   copy: src=httpd.conf dest=/data1/ owner=apache
13 [root@linux-node1 tasks]# cat user.yml 
14 - name: create user
15   user: name=apache
16 
17 #httpd.conf 模拟的测试文件

roles

1 [root@linux-node1 ansible]# cat more_role.yml 
2 - hosts: date
3   remote_user: root
4   roles:
5     - role: httpd
6     - role: nginx

more_role.yml

 2、夸项目调用别的角色（nginx调用httpd的copyfile.yml）

1 [root@linux-node1 ansible]# cat roles/nginx/tasks/main.yml 
2 - include: group.yml
3 - include: user.yml
4 - include: yum.yml
5 - include: templ.yml
6 - include: start.yml
7 - include: roles/httpd/tasks/copyfile.yml

main.yml

 3、角色写标签

1 [root@linux-node1 ansible]# cat more_role.yml 
2 - hosts: date
3   remote_user: root
4   roles:
5     - { role: httpd, tags: ['web','httpd'] }
6     - { role: nginx, tags: ['web','nginx'] }

more_role.yml

 1 [root@linux-node1 ansible]# ansible-playbook -t httpd -C more_role.yml

-t 标签，结果不同

 4、角色写标签姐when条件

[root@linux-node1 ansible]# vim more_role.yml 

- hosts: date
  remote_user: root
  roles:
    - { role: httpd, tags: ['web','httpd'] }
    - { role: nginx, tags: ['web','nginx'],when: ansible_distribution_major_version == "7" }
