通过 ansible yum 在 CentOS 7 上安装 Xfce

Question

我有一台刚从 centos/7 vagrant base box 启动的 Centos 7 机器。我通过 ansible 提供了盒子，但以下不起作用：

- name: Install xfce
  yum:
    name: "@^Xfce"
    state: present
    enablerepo: "epel"

错误是：

TASK [desktop : Install xfce] ************************************************** fatal: [xxx]: FAILED! => {"changed": false, "changes": {"installed": ["@^Xfce"]}, "msg": "Error: Nothing to do\n", "rc": 1, "results": ["Loaded plugins: fastestmirror\nLoading mirror speeds from cached hostfile\n * base: mirror.ratiokontakt.de\n * epel: mirror.de.leaseweb.net\n * extras: centos.schlundtech.de\n * updates: centos.schlundtech.de\nGroup Xfce does not exist.\n"]}

然而，运行机器内部的以下命令有效：

sudo yum --enablerepo=epel -y groups install "Xfce"

我做错了什么？

根据 yum module documentation:

Yum itself has two types of groups. “Package groups” are specified in the rpm itself while “environment groups” are specified in a separate file (usually by the distribution). Unfortunately, this division becomes apparent to ansible users because ansible needs to operate on the group of packages in a single transaction and yum requires groups to be specified in different ways when used in that way. Package groups are specified as “@development-tools” and environment groups are “@^gnome-desktop-environment”. Use the “yum group list hidden ids” command to see which category of group the group you want to install falls into.

您将组指定为 @^Xfce，这是 "environment group" 的语法，但是如果您查看 yum group list hidden ids 的输出，则没有 "Xfce" 环境组。是一个同名的包组，这个剧本似乎安装成功：

---
- hosts: localhost
  gather_facts: false
  tasks:
    - name: install xfce
      yum:
        name: "@Xfce"
        state: "present"
        enablerepo: "epel"
