|
<p>the mapper file is a file where we specify the directory where all our mounts should be placed.</p> |
|
<p>This file should be stored in <em>/etc/auto.master.d</em>, note that the extension is required to be <em>.autofs</em></p> |
|
<p>for example: <em>/etc/auto.master.d/home.autofs</em></p> |
|
<pre tabindex="0"><code class="language-.language-command" data-lang=".language-command">/home/guests /etc/auto.home |
|
|
|
</code></pre><p>The value for <em>/home/guests</em> is the file where we specify our mount options.</p> |
|
<p><strong>Note</strong>: Make sure the <em>/home/guests</em> directory exists, if not create it with:</p> |
|
<pre tabindex="0"><code class="language-.language-command" data-lang=".language-command">mkdir /home/guests |

</code></pre><h2 id="create-the-mapper-file">Create the mapper file</h2> |

<p>We earlier specified where our map file should be stored (<em>/etc/auto.home</em>), create this file.</p> |

<p>Say we want to auto mount the home directories stored on <strong>serverA</strong> on /home/guests/[<em>USER</em>] when [<em>USER</em>] logs in.</p> |

</code></pre><ul> |
|
<li>The wildcards task is to create the directory based on the users homedirectory on serverA (specified with <strong>&</strong>)</li> |
|
<li>We give option like: read/write and sync</li> |
|
<li>As last param we have to say where we want to mount to, again, the <strong>&</strong> is dynamic and maps to the logged in user.</li> |
