Ansible：role企业级实战

实现 nginx 角色

卸载httpd，创建相关目录

ansible webservers -m yum -a 'name=httpd state=absent'
mkdir -pv  playbook/roles/nginx/{
   
   tasks,handlers,templates,vars}
tree  playbook/roles/nginx

创建task文件

cd playbook/roles/nginx/tasks
vim main.yml 

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

• 安装

vim  install.yml 

- name: install
  yum: name=nginx 

• 配置

vim config.yml 

- name: config file for centos7
  template: src=nginx7.conf.j2 dest=/etc/nginx/nginx.conf
  when: ansible_distribution_major_version=="7"
  notify: restart

• 网页：引用另一个role的网页文件

vim  index.yml 

- name: index.html
  copy
