Self-host Nextcloud at home - Mon, Apr 7, 2025

This document is paired with a video linked below. Let's setup Nextcloud.

Naturally, you want to self-host Nextcloud. Let’s go through all of the requirements step-by-step.

Here are all of the commands that you are going to use that were described in the video:

# Setting-up Nginx reverse-proxy for Nextcloud

<VirtualHost *:80>
    ServerName <your-nc-domain>

    RewriteEngine On
    RewriteCond %{HTTPS} off
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
    RewriteCond %{SERVER_NAME} =<your-nc-domain>
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

<VirtualHost *:443>
    ServerName <your-nc-domain>

    # Reverse proxy based on https://httpd.apache.org/docs/current/mod/mod_proxy_wstunnel.html
    RewriteEngine On
    ProxyPreserveHost On
    RequestHeader set X-Real-IP %{REMOTE_ADDR}s
    AllowEncodedSlashes NoDecode
    
    ProxyPass / http://localhost:11000/ nocanon # Adjust to match APACHE_PORT and APACHE_IP_BINDING. See https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md#adapting-the-sample-web-server-configurations-below
    ProxyPassReverse / http://localhost:11000/ # Adjust to match APACHE_PORT and APACHE_IP_BINDING. See https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md#adapting-the-sample-web-server-configurations-below
    
    RewriteCond %{HTTP:Upgrade} websocket [NC]
    RewriteCond %{HTTP:Connection} upgrade [NC]
    RewriteCond %{THE_REQUEST} "^[a-zA-Z]+ /(.*) HTTP/\d+(\.\d+)?$"
    RewriteRule .? "ws://localhost:11000/%1" [P,L,UnsafeAllow3F] # Adjust to match APACHE_PORT and APACHE_IP_BINDING. See https://github.com/nextcloud/all-in-one/blob/main/reverse-proxy.md#adapting-the-sample-web-server-configurations-below

    # If running apache on a subdomain (eg. nextcloud.example.com) of a domain that already has an wildcard ssl certificate from certbot on this machine, 
    # the <your-nc-domain> in the below lines should be replaced with just the domain (eg. example.com), not the subdomain. 
    # In this case the subdomain should already be secured without additional actions
