Cài đặt nfs trên Ubuntu bằng Ansible

1. Tạo file play book chạy cho nfs server

vi nfs.yml
cat nfs.yml 

---
- hosts: nfs-server
  become: true
  gather_facts: no
  vars:
    nfs_shares:
      - '/mnt/nfs_read'
      - '/mnt/nfs_write'
  tasks:
    - name: Installing NFS Server Packages
      apt:
        name: "{{ item }}"
        state: "present"
      with_items:
        - 'nfs-common'
        - 'nfs-kernel-server'
        - 'rpcbind'

    - name: Open ufirewall sudo ufw allow from client_ip to any port nfs
      shell: ufw allow from any to any port nfs

    - name: Crete share directory
      ansible.builtin.file:
        path: "{{ item }}"
        state: directory
        owner: nobody
        group: nogroup
      loop: "{{ nfs_shares }}"

    - name: Copy tệp từ mẫu template/exports.j2 đến /etc/exports
      template:
        src: template/exports.j2  # Đường dẫn đến mẫu Jinja2
        dest: /etc/exports  # Đường dẫn đích
        owner: root
        group: root
        mode: "0644"

    - name: export folder
      shell: exportfs -a

    - name: Enable and start nfs-kernel-server
      ansible.builtin.systemd_service:
        state: started
        name: nfs-kernel-server
        state: started
        enabled: true

    - name: restart nfs-server
      service:
        name: "nfs-kernel-server"
        state: "restarted"
        enabled: true

Tạo file template template/exports.j2

cat ./template/exports.j2
{% for nfs_share in nfs_shares %}
{{ nfs_share }} 10.1.1.0/24(rw,sync,no_subtree_check)
{% endfor %}

Chạy playbook trên server:

ansible-playbook --limit nfs-server nfs.yml

2. Tạo playbook cho client

- name: Run on nfs client
  hosts: nfs-client
  gather_facts: no
  become: true
  vars:
    nfs_shares:
      - '/mnt/nfs_read'
      - '/mnt/nfs_write'
    nfs_server_ip: "10.1.1.20"
  tasks:
    - name: Installing NFS client Packages
      apt:
        name: "{{ item }}"
        state: "present"
      with_items:
        - 'nfs-common'

    - name: Create share directory
      ansible.builtin.file:
        path: "{{ item }}"
        state: directory
        owner: nobody
        group: nogroup
      loop: "{{ nfs_shares }}"

    - name: Client mount folder
      shell: "mount {{ nfs_server_ip }}:{{ item }} {{ item }}"
      loop: "{{ nfs_shares }}"

    - name: add fstab
      lineinfile:
        path: "/etc/fstab"
        regexp: "{{ item }}"
        line:  "{{ nfs_server_ip }}:{{ item }} {{ item }} nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0"
        state: present
      loop: "{{ nfs_shares }}"

Chạy playbook trên Client:

ansible-playbook --limit nfs-client nfs.yml
