In the realm of network file sharing, Samba stands out as a robust, open-source solution that enables seamless interoperability between Unix/Linux and Windows systems. However, deploying and configuring Samba across various Linux distributions in a multi-server environment can be a daunting task. This is where Ansible, a powerful automation tool, comes into play. Ansible simplifies the process, ensuring consistency and efficiency. This article aims to demystify the process of automating Samba installations with Ansible, making it accessible even to newcomers in the field.

Understanding Ansible and Samba

Before diving into automation, let’s clarify what Ansible and Samba are. Ansible is an open-source automation tool that automates software provisioning, configuration management, and application deployment. It uses a simple syntax written in YAML, called playbooks, to describe automation jobs. Samba, on the other hand, is a free software that provides secure, stable, and fast file and print services for all clients using the SMB/CIFS protocol.

Setting Up Your Ansible Environment

First, ensure Ansible is installed on your control node (the system you’ll use to run Ansible commands). For most Linux distributions, you can install Ansible using your package manager. For instance, on Ubuntu, you’d use:

sudo apt update
sudo apt install ansible -y

Once Ansible is installed, you need to set up your inventory file. This file lists all the servers you wish to automate. Create an inventory file named hosts in the /etc/ansible/ directory or a directory of your choice, and add your servers under a group [samba_servers]:

[samba_servers]
server1 ansible_host=192.168.1.10
server2 ansible_host=192.168.1.11

Creating the Ansible Playbook for Samba Installation

An Ansible playbook is a blueprint of automation tasks, which are executed sequentially. Create a file named samba_install.yml and add the following contents:

---
- name: Install and Configure Samba
  hosts: samba_servers
  become: yes
  tasks:
    - name: Install Samba
      package:
        name: samba
        state: present
      when: ansible_facts['os_family'] == "Debian" or ansible_facts['os_family'] == "RedHat"

    - name: Configure smb.conf
      template:
        src: smb.conf.j2
        dest: /etc/samba/smb.conf
      notify: restart samba

  handlers:
    - name: restart samba
      service:
        name: smbd
        state: restarted

This playbook performs two main tasks: installing Samba and configuring it using a template file (smb.conf.j2). The when condition ensures that the Samba package is installed only on supported distributions (Debian/Ubuntu or RedHat/CentOS). The handlers section defines tasks that are triggered by other tasks; in this case, restarting Samba when its configuration changes.

Creating the Samba Configuration Template

The smb.conf.j2 template file allows you to customize Samba settings. Create this file with the necessary configurations for your environment. Here’s a basic example:

[global]
   workgroup = WORKGROUP
   server string = Samba Server
   log file = /var/log/samba/log.%m
   max log size = 50
   security = user
   passdb backend = tdbsam

[shared]
path = /srv/samba/shared 
writable = yes 
guest ok = yes guest 
only = yes read 
only = no

Running the Playbook

With the playbook and template ready, execute the playbook using the following command:

ansible-playbook -i /path/to/your/hosts samba_install.yml

This command runs the playbook on the hosts defined in your inventory file, automating the Samba installation and configuration process across all specified servers.
