Ansible：如何安装多个rpm但每个操作系统一个？

Question

我想安装多个rpm，一个用于Fedora服务器，另一个用于Centos服务器。我已经完成了此剧本文件，但有错

- name: Copy rpm file to server
  hosts: fedora
  copy:
     src: /tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm
     dest: /tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm

- name: Install package.
  hosts: fedora
  yum:
     name: /tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm
     state: present

- name: Copy another rpm file to server
  hosts: centos
  copy:
     src: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
     dest: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm

- name: Install another package.
  hosts: centos
  yum:
     name: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
     state: present

Answer 1

您的剧本应该可以使用，但是您可以通过添加when语句来加倍保护自己：

- name: Copy another rpm file to server
  hosts: centos
  copy:
     src: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
     dest: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
  when:
    - ansible_facts['distribution'] == "CentOS"

- name: Install another package.
  hosts: centos
  yum:
     name: /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
     state: present
  when:
    - ansible_facts['distribution'] == "CentOS"

Answer 2

我用一些不同的语法解决了

- name: Transfer and install a rpm for Centos server
  hosts: centos
  become_user: root
  tasks:
     - name: Copy another rpm file to server
       copy: src=/tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm dest=/tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm
     - name: Install the rpm
       command: dnf -y localinstall /tmp/pam_krb5-2.4.8-6.el8.x86_64.rpm

- name: Transfer and install a rpm for Fedora server
  hosts: fedora
  become_user: root
  tasks:
     - name: Copy another rpm file to server
       copy: src=/tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm dest=/tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm
     - name: Install the rpm
       command: dnf -y localinstall /tmp/pam_krb5-2.4.8-6.fc31.x86_64.rpm

Answer 3

您可以使用2个vars文件（每个发行版一个）：

vars / centos_8.yml

packages:
  - pam_krb5-2.4.8-6.el8.x86_64.rpm
  - ...

vars / fedora_31.yml

packages:
  - pam_krb5-2.4.8-6.fc31.x86_64.rpm
  - ...

然后在您的任务中，您可以执行以下操作：

- name: Include vars for host distribution
  include_vars: "{{ ansible_distribution|lower }}_{{ ansible_distribution_major_version }}.yml"

- name: Copy RPM files to server
  copy:
     src: /tmp/{{ item }}
     dest: /tmp/{{ item }}
  with_items:
    - "{{ packages }}" 

- name: Install RPM packages
  yum:
     name: /tmp/{{ item }}
     state: present
  with_items:
    - "{{ packages }}"
