套件管理 - yum 模組

1. yum 模組可以做套件管理，完整文件可用 ansible-doc 查詢 yum 模組文件。

   [root@kvm19 ansible]# ansible-doc yum
   

2. 確認 dev 群組裡所有主機，套件 vim 還沒安裝，回傳成功。

   [deyu1@kvm19 ansible]$ ansible dev -m yum -a "name=vim state=absent"
   kvm11 | SUCCESS => {
       "ansible_facts": {
           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": false,
       "msg": "Nothing to do",
       "rc": 0,
       "results": []
   }
   

3. 使用 yum 模組安裝 vim 至最新版本，回傳成功，含相依套件共安裝了 4 的套件。

   [deyu1@kvm19 ansible]$ ansible dev -m yum -a "name=vim state=latest"
   kvm11 | CHANGED => {
       "ansible_facts": {
           "discovered_interpreter_python": "/usr/libexec/platform-python"
       },
       "changed": true,
       "msg": "",
       "rc": 0,
       "results": [
           "Installed: gpm-libs-1.20.7-15.el8.x86_64",
           "Installed: vim-enhanced-2:8.0.1763-10.el8.x86_64",
           "Installed: vim-filesystem-2:8.0.1763-10.el8.noarch",
           "Installed: vim-common-2:8.0.1763-10.el8.x86_64"
       ]
   }
