ansible-playbook 基礎介紹

playbook是由一個或多個模塊組成的，使用多個不同的模塊，完成一件事情。
playbook通過yaml語法識別描述的狀態文件。擴展名是yaml

1.YAML三板斧

• 縮進

  • YAML使用一個固定的縮進風格表示層級結構,每個縮進由兩個空格組成, 不能使用tabs

• 冒號

  • 以冒號結尾的除外，其他所有冒號后面所有必須有空格。

• 短橫線

  • 表示列表項，使用一個短橫杠加一個空格。
  • 多個項使用同樣的縮進級別作為同一列表。

• 安裝httpd服務->playbook
  1.安裝
  2.配置
  3.啟動

2. ansible playbook 安裝apache 示例

[root@m01 ansible_playbook]# vim  webserver.yaml
- hosts: web
  tasks:
    - name: Install Httpd Server
      yum: name=httpd,httpd-tools state=installed

    - name: Configgure Httpd Server
      copy: src=./file/httpd.conf dest=/etc/httpd/conf/httpd.conf
      notify: Resart Httpd Server

    - name: Start Httpd Server
      service: name=httpd state=started enabled=yes

  handlers:
    - name: Resart Httpd Server
      service: name=httpd state=restarted
