Ubuntu Server Installation - Nextcloud¶

Part 1: Setting Up Cloudflare¶

Ensure Your Domain Uses Cloudflare DNS
Cloudflare Zero Trust
Navigate to Network > Tunnels.
Create the tunnel and select Debian 64 Bit architecture.
Copy the Cloudflared Connector and install on Ubuntu 24.04 server
Configure Public Hostname

Part 2: Installing Nextcloud on Ubuntu Server 24.04¶

Step 1: Initial Setup¶

Install Necessary Packages:

sudo apt install -y eza redis-server build-essential unzip libmagickwand-dev librsvg2-dev libmagickcore-6.q16-7-extra

Replace .bashrc:

rm ~/.bashrc
wget https://raw.githubusercontent.com/drewgrif/jag_dots/main/.bashrc_server
mv ~/.bashrc_server ~/.bashrc
bash

Update and Upgrade:

sudo apt update && sudo apt upgrade -y && sudo apt clean

Updating hostname
```
sudo nano /etc/hostname
```
Add the subdomain from cloudflare ex: my.justaguylinux.cloud
```
sudo nano /etc/hosts
```
Add line 127.0.1.1 ex: venetian my.justaguylinux.cloud
Reboot the Server:
```
sudo reboot
```
Log Back In.

Step 2: Downloading and Installing Nextcloud¶

Download Nextcloud:

wget https://download.nextcloud.com/server/releases/latest.zip

Install MariaDB:

sudo apt install -y mariadb-server
sudo mysql_secure_installation

Create Nextcloud Database:

sudo mariadb

Inside the MariaDB shell:

CREATE DATABASE nextcloud;
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY 'mypassword';
FLUSH PRIVILEGES;

Exit with CTRL+D.

Step 3: Set Up Apache Webserver¶

Install Required PHP Packages:

sudo apt install php php-apcu php-bcmath php-cli php-common php-curl php-gd php-gmp php-imagick php-intl php-mbstring php-mysql php-zip php-xml php-redis

Enable Apache Modules:

sudo a2enmod dir env headers mime rewrite ssl

sudo phpenmod bcmath gmp imagick intl redis

Unzip Nextcloud:
```
unzip latest.zip
```

Rename nextcloud to subdomain

mv nextcloud my.justaguylinux.cloud

5. Change nextcloud ownership

sudo chown -R www-data:www-data my.justaguylinux.cloud

Move nextcloud to apache

sudo mv my.justaguylinux.cloud /var/www

7. Disable default apache site

sudo a2dissite 000-default.conf

Configure Apache for Nextcloud:

sudo nano /etc/apache2/sites-available/my.justaguylinux.cloud.conf

Add the following content:

<VirtualHost *:80>
    DocumentRoot "/var/www/my.justaguylinux.cloud"
    ServerName my.justaguylinux.cloud

    <Directory "/var/www/my.justaguylinux.cloud/">
        Options MultiViews FollowSymlinks
        AllowOverride All
        Require all granted
    </Directory>

    TransferLog /var/log/apache2/my.justaguylinux.cloud_access.log
    ErrorLog /var/log/apache2/my.justaguylinux.cloud_error.log
</VirtualHost>

Enable Nextcloud Site and Restart Apache:

sudo a2ensite my.justaguylinux.cloud.conf
sudo systemctl restart apache2

Installing SSL¶

sudo snap install core; sudo snap refresh core

Install Certbot:

sudo snap install --classic certbot

sudo ln -s /snap/bin/certbot /usr/bin/certbot

Attempt to obtain a certificate (DNS must have already propagated):

sudo certbot --apache

Step 4: Adjust PHP Settings¶

Edit PHP Configuration:
```
sudo nano /etc/php/8.3/apache2/php.ini
```
php.ini

Some of these will need changed others will need uncommnented and changed.

memory_limit = 512M

upload_max_filesize = 2G

max_execution_time = 360

post_max_size = 2G

date.timezone = America/New_York

opcache.enable = 1

opcache.interned_strings_buffer = 32

opcache.max_accelerated_files = 10000

opcache.memory_consumption = 128

opcache.save_comments = 1

opcache.revalidate_freq = 1

Enable acpu module

sudo nano /etc/php/8.3/mods-available/apcu.ini

Add to the file: apc.enable_cli=1

Restart Apache:
```
sudo systemctl restart apache2
```

Step 5: Nextcloud via Web Browser¶

Install via Web: https://my.justaguylinux.cloud
Install recommended applications

Part 3: Dealing with Warnings¶

Change config.php permissions

sudo chmod 660 /var/www/my.justaguylinux.cloud/config/config.php

Detected some missing optional indices.

Make occ executable:

sudo chmod +x /var/www/my.justaguylinux.cloud/occ

Then add missing indices:

sudo -u www-data /var/www/my.justaguylinux.cloud/occ db:add-missing-indices

Check to see if error is no longer

One or more mimetype migrations are available

sudo -u www-data /var/www/my.justaguylinux.cloud/occ maintenance:repair --include-expensive

The following warnings

Server has no maintenance window start time configured.
The database is used for transactional file locking.
No memory cache has been configured.
Your installation has no default phone region set.
You have not set or verified your email server configuration yet.

sudo nano /var/www/my.justaguylinux.cloud/config/config.php

Remove: maintenance => false,

Add:

'mail_smtpmode' => 'smtp',
'mail_sendmailmode' => 'smtp',
'mail_domain' => 'gmail.com',
'mail_smtphost' => 'smtp.gmail.com',

),
'default_phone_region' => 'US',
'overwriteprotocol' => 'https',

**Some headers are not set correctly on your instance - The Strict-Transport-Security HTTP header is not set (should be at least 15552000 seconds). **
```
sudo nano /etc/apache2/sites-available/my.justaguylinux.cloud-le-ssl.conf
```
**Add after

```SSL configuration (done by Certbot) SSLCertificateFile /etc/letsencrypt/live/my.justaguylinux.cloud/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/my.justaguylinux.cloud/privkey.pem

Paste

HSTS header¶

Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains; preload"

bash sudo systemctl restart apache2 ```
