How to set up your own cloud using Nextcloud on Archlinux

Note: this post was updated at 2020-01-21 to ensure compatibilty with latest Nextcloud 18 and PHP 7.4

After writing this post regarding how I use my todo.txt file, I realized that it was time to set up a Nextcloud server (again) the soonest possible so that I will be aple to stop relying on proprietary services like Dropbox.

All I needed was:

Although being an Archlinux user for more 10 years, when it’s time to set up a server for something more “crucial”, I usually choose Debian.

This time I chose to go with Archlinux and below I will write a short guide on how you can do the same with me and have your own self-hosted cloud implementation using Archlinux/Nextcloud/Nginx/Mariadb/PHP-fpm.

Note: I am very far from being an Nginx/Mariadb/PHP expert. I can’t guarantee that the suggested configuration will be secure enough for your custom needs. Please read and follow these instructions at your own risk!

Scaleway and Archlinux

The Archlinux image Scaleway uses is not trouble-free. Something is not right with their permissions, so if you get errors like:

warning: directory permissions differ on /usr/
filesystem: 775  package: 755	

A quick workaround is to give the following commands:

chmod 755 /usr /etc /usr/local /usr/local/sbin /usr/local/bin
chmod 755 /etc/sysctl.d/ /etc/systemd/ /etc/systemd/network/ /etc/systemd/system	

Last but not least, Scaleway blocks SMTP by default, so you will need to go to security settings, modify and do a hard reboot from the web interface. This way you will be able to use custom Nextcloud SMTP settings for email notifications.

The “basic” stuff

When you log in for the first time, change your password:


Archlinux is a rolling release distro, so a good idea for a “first step” is to upgrade the OS:

pacman -Sy archlinux-keyring && pacman -Syyu

Then, set a custom hostname:

hostnamectl set-hostname abyss 

Finally, I strongly suggest you to change the SSH port:

nano /etc/ssh/sshd_config

and restart the service:

systemctl restart sshd

Note: I highly suggest you to spend some time in this Archwiki firewall section and choose a solution for your VPS. As I am not a security expert, this procedure will not be covered by this article!

The “database” stuff

Nextcloud needs a database, so you will have to install and configure mariadb and then create a database to be used with Nextcloud:

Install the package:

pacman -S mariadb

Proceed with the initial configuration:

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

Start and enable the services:

systemctl start mariadb
systemctl enable mariadb

Secure the mariadb configuration:


Create the database for Nextcloud:

mysql -u root -p
CREATE DATABASE `nextclouddb` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
CREATE USER `nextcloud_user`@'localhost' IDENTIFIED BY 'arandompassword';
GRANT ALL PRIVILEGES ON `nextclouddb`.* TO `nextcloud_user`@`localhost`;

The “PHP” stuff

Install the needed packages:

pacman -S php php-fpm php-intl php-gd php-apcu

Edit php.ini:

nano /etc/php/php.ini

and enable the following lines:


Add this block for APC:

and this one for opcache:


You should also have a look at these settings I use, enable the lines and modify as per your own needs:

post_max_size = 7G
upload_max_filesize = 7G
max_input_time = 3600
max_execution_time = 3600
output_buffering = Off

Edit the following file:

nano /etc/php/php-fpm.d/www.conf

and enable this line:

env[PATH] = /usr/local/bin:/usr/bin:/bin

If you use php-fpm 7.4 you need to do the following:

systemctl edit php-fpm.service

and save the following content:

ReadWritePaths = /usr/share/webapps/nextcloud/apps
ReadWritePaths = /etc/webapps/nextcloud/config

# Replace the following path with the Nextcloud data directory
ReadWritePaths = /usr/share/webapps/nextcloud/data/

Replace the following path with the Nextcloud data directory

ReadWritePaths = /var/nextcloud

ReadWritePaths = /usr/share/webapps/nextcloud/apps
ReadWritePaths = /etc/webapps/nextcloud/config

Finally, start and enable the service:

systemctl enable php-fpm
systemctl start php-fpm

The “Nginx” stuff

Install the needed packages:

pacman -S nginx-mainline wget certbot certbot-nginx

create the needed directory structure:

mkdir /etc/nginx/conf.d/

Get the initial Nginx configuration file to use in order to get the SLL certificate:

wget -O /etc/nginx/conf.d/nextcloud.conf

Note: You will need to edit this file and change “@@FQDN@@” with your domain.

Edit nginx.conf

nano /etc/nginx.conf

and put the following line in http section (I put it as a first line):

include /etc/nginx/conf.d/*;

Enable and start the service:

systemctl enable nginx
systemctl start nginx

Now it’s time to get the certificate:

certbot --nginx

When certbot is finished, download the final nginx configuration:

wget -O /etc/nginx/conf.d/nextcloud.conf

Note: You will need to edit this file and change “@@FQDN@@” with your domain one more time.

Now install cronie in order to use cron jobs:

pacman -S cronie

start and enale the service:

systemctl start cronie.service
systemctl enable cronie.service

Give the following command:

crontab -e

and put the following line:

* 4 * * * /usr/bin/certbot renew >/dev/null 2>&1

The “Nextcloud” stuff

Install the package:

pacman -S nextcloud

Create directory structure and modify permissions:

chown http:http /usr/share/webapps/nextcloud/
chmod 750 /usr/share/webapps/nextcloud/
mkdir -p /usr/share/webapps/nextcloud/data
chown http:http /usr/share/webapps/nextcloud/data
chown http:http /usr/share/webapps/nextcloud/apps
chmod 750 /usr/share/webapps/nextcloud/data
chmod 750 /usr/share/webapps/nextcloud/apps

and now you ’re ready to visit your **https:// **domain and start the installation.

After in less than a minute your self-hosted cloud application will be ready to use!

Further improvements:

- Enable APC caching

nano /etc/webapps/nextcloud/config/config.php

and add:

'memcache.local' => '\OC\Memcache\APCu',

restart nginx and php-fpm:

systemctl restart nginx php-fpm

- Enable encryption

Read the following guide:

- Use cron

crontab -u http -e

and add:

*/15  *  *  *  * php -f /usr/share/webapps/nextcloud/cron.php

Finally, check your settings to ensure that the Background Jobs are set to use Cron.

- Use a custom SMTP server for email notificartions

Read the following guide:

- Use a custom theme with auto-generated favicon.ico

You will need php-imagick from AUR (ex. with yaourt ) plus some official packages:

pacman -S imagemagick librsvg
