更新套件

1. 修改腳本 deploy3.yml 為 deploy4.yml，增加任務在 test 更新open開頭的套件。

   [deyu1@kvm19 ansible]$ cat deploy4.yml
   ---
   - hosts: dev test
     tasks:
     - name: install package
       yum: 
         name:
         - php
         - mariadb
         state: latest
     - block:
       - name: install the '@RPM Development Tools' package group
         yum:
           name: "@RPM Development Tools"
           state: present
       - name: upgrade all packages
         yum:
           name: 'open*' 
           state: latest    
       when: "'test' in group_names"
   

2. 命令列使用 ansible-playbook 執行 deploy4.xml 腳本。

   [deyu1@kvm19 ansible]$ ansible-playbook deploy4.yml
