ansible: 项目实战

备注：

ansible-galaxy list  显示的是默认从网上下载的路径 

# /usr/share/ansible/roles
# /etc/ansible/roles

示例1： 批量安装httpd/

（1）创建文件目录

 （2）创建roles/httpd/tasks，下面存放以下文件

- include: install.yml
- include: config.yml
- include: index.yml
- include: start_service.yml

- name: config file
  copy: src=httpd.conf dest=/etc/httpd/conf/ backup=yes
  notify: restart

- name: install httpd
  yum: name=httpd

- name: index.html
  copy: src=index.html dest=/var/www/html/

- name: start serivce
  service: name=httpd state=started enabled=yes

(3)创建roles/httpd/files 文件夹，存放我们配置文件

（4）创建roles/httpd/handles 文件夹，内存放main.yml

- name: restart
  service: name=httpd state=restarted

 

 (5) 在playbook中调用的角色，文件要和roles平级

---
# http role
- hosts: testserver
  remote_user: root

  roles:
    -role:httpd

(6) 执行playbook

[root@zhu data]# ansible-playbook /data/roles_httpd.yml
