Cloud Server Using Nextcloud

Prerequisites And Assumptions

  • Server running Rocky Linux (you can install Nextcloud on any Linux distribution, but this procedure will assume you're using Rocky).
  • A high degree of comfort operating from the command line for installation and for configuration.
  • Knowledge of a command-line editor. For this example, we are using vi, but you can use your favorite editor if you have one.
  • While Nextcloud can be installed via a snap application, we will be downloading and installing the .zip file.
  • We will be applying concepts from the Apache sites enabled document (linked to later in this document) for directory setup.
  • We will also be using the mariadb-server hardening procedure (also linked to later) for database setup.
  • Throughout this document we will assume that you are root, or that you can be by using sudo.
  • We are using an example domain of "" throughout this document.


If you are in charge of a server environment for a large (or even a small) company, you may be tempted by cloud applications. Doing things in the cloud can free up your own resources for other things, but there is a downside to this, and that is the loss of control of your company's data. If the cloud application is compromised, so too may be your company's data.

Taking the cloud back into your own environment is a way to reclaim security of your data at the expense of your time and energy. Sometimes, that is a cost worth paying.

Nextcloud offers an open source cloud with security and flexibility in mind. Note that building a Nextcloud server is a good exercise, even if in the end you opt to take your cloud off-site. The following procedure deals with setting up Nextcloud on Rocky Linux.

Installing And Configuring Repositories

For this installation, we need to install the EPEL (Extra Packages for Enterprise Linux).

To install the EPEL run:

dnf install epel-release

And then once installed, run an update to make sure you are at the very latest EPEL version:

dnf update

Rocky Linux comes with PHP 7.2 enabled, but we need PHP 7.4. This is now a module.

dnf module list php

Which should give you output like this:

Rocky Linux 8 - AppStream
Name                    Stream                     Profiles                                     Summary                                 
php                     7.2 [d]                    common [d], devel, minimal                   PHP scripting language                  
php                     7.3                        common [d], devel, minimal                   PHP scripting language                  
php                     7.4                        common [d], devel, minimal                   PHP scripting language               

Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled

We want to grab the newest PHP that Nextcloud is compatible with, which at this moment is 7.4, so we will enable that module by doing:

dnf module enable php:7.4

To see how this changes the output of the module list, run that command again and you will see the "[e]" next to 7.4:

dnf module list php

And the output again is the same except for this line:

php 7.4 [e] common [d], devel, minimal PHP scripting language

Installing Packages

We need a number of packages installed. Some of these may already be installed with your default Rocky Linux installation, but make sure by running the following:

dnf install httpd mariadb-server vim wget zip unzip libxml2 openssl php php-common php-gd php-json php-mbstring php-process php-xml php-zip php-pdo php-mysqlnd php-intl php-bcmath php-gmp

Configuring Packages And Directories

Configuring apache

Set apache to start on boot:

systemctl enable httpd

As noted earlier, we are using the "Apache Sites Enabled" procedure found here to configure Apache. Follow that guide to get the configuration directories setup and the httpd.conf file modified and then return to this document for the remaining steps.

Create The Configuration

For Nextcloud, we will need to create the following configuration file.

vi /etc/httpd/sites-available/com.yourdomain.nextcloud

Your configuration file should look something like this:

<VirtualHost *:80>
  DocumentRoot /var/www/sub-domains/com.yourdomain.nextcloud/html/

  <Directory /var/www/sub-domains/com.yourdomain.nextcloud/html/>
    Require all granted
    AllowOverride All
    Options FollowSymLinks MultiViews

    <IfModule mod_dav.c>
      Dav off

Once done, save your changes (with SHIFT:wq! for vi).

Next, create a link to this file in /etc/httpd/sites-enabled:

ln -s /etc/httpd/sites-available/com.yourdomain.nextcloud /etc/httpd/sites-enabled/

Creating The Directory

As noted in the configuration above, the DocumentRoot needs to be created. This can be done by:

mkdir -p /var/www/sub-domains/

This is where our Nextcloud instance will be installed.

Configuring PHP

Find your timezone. This can be done by:

cd /usr/share/zoneinfo

If you are in the Central timezone, for instance, you could either use "US/Central" or "America/Chicago" and either setting would work. Once you have identified your timezone, the next thing we need to do is populate the php.ini file with this information.

To do this:

vi /etc/opt/remi/php74/php.ini

Then find this line:

;date.timezone =

For our example timezone, we would put in either of the two options:

date.timezone = "America/Chicago"


date.timezone = "US/Central"

Note that for the sake of keeping things the same, your timezone in the php.ini file should match up to your machine's timezone setting. You can find out what this is set to by doing the following:

ls -al /etc/localtime

Which should show you something like this, assuming you set your timezone when you installed Rocky Linux and are living in the Central time zone:

/etc/localtime -> /usr/share/zoneinfo/America/Chicago

Configuring mariadb-server

Set mariadb-server to start on boot:

systemctl enable mariadb

And then start it:

systemctl restart mariadb

Again, as indicated earlier, we will be using the setup procedure for hardening mariadb-server found here for the initial configuration.

Installing Nextcloud

There are several ways to install Nextcloud which you can review on the web site under the manual for installation. What we will be using here is the server install .zip file.

Get The Nextcloud .zip File And Unzip

The next few steps assume that you are remotely connected to your Nextcloud server via ssh with a remote console open:

  • Navigate to the Nextcloud web site
  • Let your mouse hover over "Get Nextcloud" which will bring up a drop down menu.
  • Click on "Server Packages".
  • Right-click on "Download Nextcloud" and copy the link address. (the exact syntax of this is different browser to browser)
  • In your remote console on the Nextcloud server, type "wget" and then a space and paste in what you just copied. You should get something like the following: wget
  • Once you hit enter, the download of the .zip file will start and will be completed fairly quickly.

Once the download is complete, unzip the nextcloud zip file by using the following:


Copying Content And Changing Permissions

After completing the unzip step, you should now have a new directory in /root called "nextcloud." Change into this directory:

cd nextcloud

And either copy or move the content to our DocumentRoot:

cp -Rf * /var/www/sub-domains/com.yourdomain.nextcloud/html/


mv * /var/www/sub-domains/com.yourdomain.nextcloud/html/

Now that everything is where it should be, the next step is to make sure that apache owns the directory. To do this:

chown -Rf apache.apache /var/www/sub-domains/com.yourdomain.nextcloud/html

For security reasons, we also want to move the "data" folder from inside to outside of the DocumentRoot. Do this with the following command:

mv /var/www/sub-domains/com.yourdomain.nextcloud/html/data /var/www/sub-domains/com.yourdomain.nextcloud/

Configuring Nextcloud

Now comes the fun! First, make sure that you have your services running. If you followed the above steps, they should already be running. We have had several steps between those initial service starts, so let's go ahead and restart them, just to be sure:

plain text systemctl restart httpd systemctl restart mariadb

If everything restarts and there are no issues, then you are ready to move on.

To do the initial configuration, we want to actually load the site in a web browser:

And you should see this screen:

nextcloud login screen

There are a couple of things that we want to do differently than the defaults that show up:

  • At the top of the web page, where it says "Create an admin account", set the user and password. For the sake of this document, we are entering "admin" and setting a strong password. Remember to save this somewhere safe (like a password manager) so that you don't lose it! Even though you have typed into this field, don't hit 'Enter' until we have done all of the setup fields!
  • Under the "Storage & database" section, change the "Data folder" location from the default document root, to where we moved the data folder earlier: /var/www/sub-domains/com.yourdomain.nextcloud/data
  • Under the "Configure the database" section, change from "SQLite" to "MySQL/MariaDB" by clicking on that button.
  • Type the MariaDB root user and password that you set earlier into the "Database user" and "Database password" fields
  • In the "Database name" field, type "nextcloud"
  • In the "localhost" field, type "localhost:3306" (3306 is the default mariadb connect port)

Now cross your fingers and click "Finish Setup".

The browser window will refresh for a bit and then usually not reload the site. Enter your URL in the browser window again and you should be confronted with the default first pages. Your administrative user is already (or should be) logged in at this point, and there are several informational pages designed to get you up to speed.

The "Dashboard" is what users will see when they first login. The administrative user can now create other users, install other applications and many other tasks.

The "Nextcloud Manual.pdf" is the user manual, so that users can get familiar with what is available. The administrative user should read through or at least scan the high points of the admin manual On the Nextcloud web site

Next Steps

At this point, don't forget that this is a server that you will be storing company data on. It's important to get it locked down with a firewall, get the backups setup, secure the site with an SSL, and any other duties that are required to keep your data safe.


A decision to take the company cloud in house is one that needs to be evaluated carefully. For those that decide that keeping company data locally is preferable over an external cloud host, Nextcloud is a good alternative.
