Question

我正在尝试在 AWS ec2 实例中使用 ansible 自动安装 grafana apache_exporter。在尝试运行 ansible 剧本时，我收到错误："dest must be an existing dir "。谁能帮我解决这些问题。

如错误所说，在Ansible unarchive模块中，dest参数设置的路径必须存在。如果不存在则需要创建。

另一个问题在你的 download apache exporter 任务中，你正在将文件下载到 /opt/apache_exporter 这是一个文件，但使用与 dest 相同的路径用于 unarchive任务。

您需要为这些路径使用单独的名称并预先创建目录。以下剧本应该可以解决您的问题。

- name: download apache exporter
  get_url:
    url: https://github.com/Lusitaniae/apache_exporter/releases/download/v{{ apache_exporter_version }}/apache_exporter-{{ apache_exporter_version }}.linux-amd64.tar.gz
    dest: /opt/apache_exporter.tar.gz
- name: create /opt/apache_exporter directory for unarchiving
  file:
    path: /opt/apache_exporter
    state: directory
- name: unarchive apache exporter
  unarchive:
    remote_src: yes
    src: /opt/apache_exporter/apache_exporter-{{ apache_exporter_version }}.linux-amd64.tar.gz
    dest: /opt/apache_exporter
    creates: /opt/apache_exporter/apache_exporter-{{ apache_exporter_version }}.linux-amd64

问题出现是因为我正在运行宁干运行测试 "ansible-playbook --check" 参数，显然是因为文件模块没有在远程系统中创建目录。还解决了@sakibmoon
