<p>This tutorial assumes you already have a functioning Node.js and Caddy installation.</p>
|
|
<ol type="1">
|
|
<li>Install Oasis.</li>
|
|
</ol>
|
|
<code>git clone https://github.com/fraction/oasis.git<br />cd oasis<br />npm install</code>
|
|
<p>Test the installation by running <code>node .</code> (yes, including the period).</p>
|
|
<ul>
|
|
<li>If the output stops after a few lines and isn't an obvious Node error, hit Control and C at the same time to exit; you're ready for the <code>systemd</code> file.</li>
|
|
<li>If you get an error about port 3000 already being in use, use the command <code>node . --port PORTNUMBER</code> instead, where <code>PORTNUMBER</code> is any open port you want.</li>
|
|
</ul>
|
|
<p>If your instance immediately throws <a href="https://github.com/fraction/oasis/issues/718#issuecomment-927379995">an error about <code>ssb.friends.get</code></a>:</p>
|
|
<code>git checkout 4e8f7426a4eb1d95f6e55cf894a3168f523f8af8<br />rm -rf node_modules<br />npm install</code>
|
|
<ol start="2" type="1">
|
|
<li>Prepare the <code>systemd</code> daemon file.</li>
|
|
</ol>
|
|
<p>Edit <code>/lib/systemd/system/oasis.service</code> as root with your favorite text editor. Paste the following:</p>
|

WantedBy=multi-user.target
|
|
</pre>
|
|
<p>Replace <code>/path/to/your/node/binary</code> with whatever comes up when you run <code>which node</code>. You may need to change this if you update Node.</p>
|
|
<ol start="3" type="1">
|
|
<li>Edit your Caddyfile. (This will probably also require root.)</li>
|
|
</ol>
|
|
<pre>
|
|
yourdomain.tld {
|
|
reverse_proxy 127.0.0.1:PORTNUMBER {
|
|
header_up Host 127.0.0.1
|
|
header_up Referer http://localhost
|
|
}
|
|
basicauth * {
|
|
AnyUsernameYouWant EXTREMELYLONGCADDYHASHHERE
|
|
}
|
|
}
|
|
</pre>
|
|
<p><code>EXTREMELYLONGCADDYHASHHERE</code> is used instead of an actual password so you don't have cleartext credentials hanging around. Generate this with <code>caddy hash-password</code>. Make sure you save your actual password in a password manager, as you can't reverse a hash!</p>
|
|
<p>The <code>header_up</code> lines are there to trick Oasis into thinking it is running on a local machine, as it (very aggressively) wants to be. Normally this would be true, as Secure Scuttlebutt is peer-to-peer and intended to be run on a personal device that may see intermittent internet connectivity. However, if you're looking at this tutorial, you probably want to host a public peer as an <em>actually functioning</em> alternative to a <a href="https://github.com/ssbc/ssb-server">pub</a> or <a href="https://github.com/ssb-ngi-pointer/go-ssb-room/">room</a>.</p>

|
<ol start="4" type="1">
|
|
<li>Get everything running.</li>
|
|
</ol>
|
|
<code>sudo systemctl daemon-reload<br />sudo systemctl restart caddy<br />sudo systemctl start oasis && sudo systemctl enable oasis</code>
