ansible-playbook剧本

ansible-playbook剧本

一、部署web服务器
1、部署yum仓库
2、安装httpd
3、新建/www目录
4、在/www中新建index.html，内容为my name is liuaojie
5、该web服务器的DocumentRoot为/www
5、实现在ansible中能够使用http://node1访问到该网页内容

- name: create web service
  hosts: node1
  tasks: 
    - name: mount mnt
      mount: 
        src: /dev/cdrom
        path: /mnt
        fstype: iso9660
        state: mounted

    - name: yum_repe
      yum_repository: 
        file: baseos
        name: bb
        description: bb
        baseurl: file:///mnt/BaseOS
        enabled: yes
        gpgcheck: no

    - name: yum_repo2
      yum_repository: 
        file: appstream
        name: aa
        description: aa
        baseurl: file:///mnt/AppStream
        enabled: yes
        gpgcheck: no

    - name: install httpd
      yum: 
        name: httpd
        state: present

    - name: create /www
      file: 
        src: /var/www/html
        dest: /www
        state: link
        mode: 0775 

    - name: create /www/index.html
      copy: 
        content: "my name is liuaojie\n"
        dest: /www/index.html


    - name:  context
      file:
        path: /www/index.html
        setype: httpd_sys_content_t

    - name:  httpd.conf
      replace: 
        path: /etc/httpd/conf/httpd.conf
        regexp: 'DocumentRoot "/var/www/html"'
        replace: 'DocumentRoot "/www"'

    - name:  httpd.conf2
      replace: 
        path: /etc/httpd/conf/httpd.conf
        regexp: 
        replace: 

    - name: started httpd service 
      service: 
        name: httpd
        state: restarted
        enabled: yes

[student@ansible ansible]$ ansible-playbook liu.yml

PLAY [create web service] ******************************************************

TASK [Gathering Facts] *********************************************************
ok: [node1]

TASK [mount mnt] ***************************************************************

[student@ansible ansible]$ curl http://node1
my name is liuaojie
[student@ansible ansible]$ 

二、使用notify…handlers
1、写一个剧本runtime.yml，只对node1操作
2、创建用户aa，该用户不能用于登录，家目录/www
3、在/www创建一个文件html
4、每次执行该剧本时，将系统的当前时间输入到html文件中。
5、如果html中的时间发生变化，那么创建/tmp/kk的文件

- name: create file
  hosts: node1
  tasks:
    - name: create user
      user:
        name: aa
        shell: /sbin/nologin
        home: /www

    - name: create html
      file:
        path: /www/html
        state: touch

    - name: date
      shell: date > /www/html
      notify:
        - kk

  handlers:
    - name: kk
      file:
        path: /tmp/kk
        state: touch
