ansible中role角色的应用

[root@foundation50 .ansible]# vim ansible.cfg
[root@foundation50 .ansible]# mkdir /root/.ansible/roles 建立指定的目录
[root@foundation50 .ansible]# ansible-galaxy list 列出roles
[root@foundation50 .ansible]# cd /root/.ansible/roles/ 进入roles目录
[root@foundation50 roles]# ansible-galaxy init apache

[root@foundation50 apache]# cd vars/ 进入变量目录
[root@foundation50 vars]# vim main.yml 编辑文件

[root@foundation50 apache]# vim tasks/  进入tasks目录
[root@foundation50 tasks]# vim main.yml  编辑文件 ，不需要缩进1 ---2 # tasks file for apache3 - name: install apache4   dnf:5    name: httpd6    state: latest7 - name: config apache   都顶格写8   lineinfile:                                                               9     path: /etc/httpd/conf/httpd.conf10     regexp: "^Listen"11     line: "listen{{PORT}}"12   notify: restart apache13   changed_when: true14 15 - name: start apache  定格16   service:17     name: httpd18     state: started19     enabled: yes                                                          [root@foundation50 apache]# cd handlers/   进入触发器目录
[root@foundation50 handlers]# vim main.yml  编辑文件

# handlers file for apache
- name: restart apacheservice:name: httpdstate: restarted[root@foundation50 ~]# cd .ansible/  
[root@foundation50 .ansible]# vim roles.yml   
---
- name: test roleshosts: westosroles: - apache    如果有多个角色，依次在后面加
[root@foundation50 .ansible]# ansible-playbook  roles.yml  运行角色的作用：把playbook片段全部拆开，放到该方的位置，不会因为playbook过长而导致缩进出现问题 ，不需要缩进全是定格
