<p>Since Seafile Pro server 6.0.0, cluster deployment requires "sticky session" settings in the load balancer. Otherwise sometimes folder download on the web UI can't work properly. Read the "Load Balancer Setting" section below for details</p>
</div>
<p>Generally speaking, in order to better access the Seafile service, we recommend that you use a load balancing service to access the Seafile cluster and bind your domain name (such as <code>seafile.cluster.com</code>) to the load balancing service. Usually, you can use:</p>
<ul>
<li>Cloud service provider's load balancing service (e.g., <strong><em>AWS Elastic Load Balancer</em></strong>)</li>
<li>
<p>Deploy your own load balancing service, our document will give two of common load balance services:</p>
<ul>
<li><strong><em>Nginx</em></strong></li>
<li><strong><em>HAproxy</em></strong></li>
</ul>
</li>
</ul>

<p>In the AWS ELB management console, after you've added the Seafile server instances to the instance list, you should do two more configurations.</p>
<p>First you should setup HTTP(S) listeners. Ports 443 and 80 of ELB should be forwarded to the ports 80 or 443 of the Seafile servers.</p>
<p>Then you setup health check</p>
<p><img alt="elb-health-check" src="../../images/elb-health-check.png" /></p>

<p>Now you should be able to test your cluster. Open <a href="https://seafile.example.com">https://seafile.example.com</a> in your browser and enjoy. You can also synchronize files with Seafile clients.</p>

<p>Here is the summary of configurations at the front-end node that related to cluster setup. (for version 7.1+)</p>
<p>For <strong>seafile.conf</strong>:</p>
<div class="highlight"><pre><span></span><code>[cluster]
enabled = true
</code></pre></div>
<p>The <code>enabled</code> option will prevent the start of background tasks by <code>./seafile.sh start</code> in the front-end node. The tasks should be explicitly started by <code>./seafile-background-tasks.sh start</code> at the back-end node.</p>
<p>For <strong>seahub_settings.py</strong>:</p>
<div class="highlight"><pre><span></span><code>AVATAR_FILE_STORAGE = &#39;seahub.base.database_storage.DatabaseStorage&#39;
</code></pre></div>
<p>For <strong>seafevents.conf</strong>:</p>
<div class="highlight"><pre><span></span><code>[INDEX FILES]
enabled = true
interval = 10m
highlight = fvh # This configuration is for improving searching speed
es_host = &lt;IP of background node&gt;
es_port = 9200
</code></pre></div>
<p>The <code>[INDEX FILES]</code> section is needed to let the front-end node know the file search feature is enabled.</p>
<h2 id="https">HTTPS<a class="headerlink" href="#https" title="Permanent link">&para;</a></h2>
<p>You can engaged HTTPS in your load balance service, as you can use certificates manager (e.g., <a href="https://certbot.eff.org">Certbot</a>) to acquire and enable HTTPS to your Seafile cluster. You have to modify the relative URLs from the prefix <code>http://</code> to <code>https://</code> in <code>seahub_settings.py</code> and <code>.env</code>, after enabling HTTPS.</p>
<h2 id="optional-deploy-seadoc-server">(Optional) Deploy SeaDoc server<a class="headerlink" href="#optional-deploy-seadoc-server" title="Permanent link">&para;</a></h2>
<p>You can follow <a href="../../extension/setup_seadoc/">here</a> to deploy SeaDoc server. And then modify <code>SEADOC_SERVER_URL</code> in your <code>.env</code> file</p>
