NextCloud is a Dropbox-like solution for self-hosted file sharing and syncing. Installing NextCloud on Ubuntu is trivial. Whether you want to backup, have file-syncing or just have a Google Calendar alternative, this guide is for you.

What is NextCloud? Is it like a “cloud”?

If you stumbled here by chance and don’t know what NextCloud is, here is an article explaining its principal features and advantages/disadvantages. In this other article you can find NextCloud 12 new features. To tell you the truth, NextCloud is a SaaS cloud, if you want to know more about cloud types you can read this article.

In this article we will cover the installation of the server (not the client).

Step1: Install software

Important
I take absolutely NO responsibility of what you do with your machine; use this tutorial as a guide and remember you can possibly cause data loss if you touch things carelessly.

The first step in order to install NextCloud 12 is to install a web server and PHP. Although you can adapt this guide for many Ubuntu versions I suggest you to stick with Ubuntu 16.04 or higher since PHP7 is included. PHP7 brings many improvements over the past versions and will boost NextCloud too, as a matter of fact PHP7 is required since NextCloud 11. You will need root access during this procedure. The following procedure will install apache as webserver. Input the commands one by one to avoid errors!

Open a terminal and input the following commands:

Step2: Database selection

Now that you have set up the environment, all that is left is to choose a database that will support the installation. You have three choices:

  • SQLite: is a single-file database. It is suggested only for small installations since it will slow NextCloud down sensibly.
  • MariaDB/MySQL: are popular open source databases especially amongst web developers. It is the suggested choice.
  • PostgreSQL: a popular enterprise-class database. More complicated than MySQL/MariaDB.

Now, this choice won’t really alter the functionality of NextCloud (except if you use SQLite), so pick whatever you know best. If you’re unsure pick MariaDB/MySQL.

Or if you prefer MySQL:

During the installation you will be prompted to choose a root password, pick a strong one. If you’re not prompted to choose a password, the default one will be blank. (This is potentially insecure, change it!)

Now you need to enter the database (you will be asked the password you just set):

Now that you are in create a database:

Now you need to create the user that will be used to connect to the database:

The last step is to grant the privileges to the new user:

When you’re done type Ctrl-D to exit.

When you’re done type \q and press enter to exit.

Step 3: Install NextCloud

The last step is to actually get the software, configure it and run it.

Ubuntu 16.04

With these step we download the software and extract it:

Now we need to create a new file in /etc/apache2/sites-available/nextcloud.conf . Feel free to use whatever editor you feel comfortable with and add the following lines:

Once done it’s time to enable the new site and enable apache mods that are needed by NextCloud:

Step 4: Install

Once you’re done with selecting the database, it’s time to install everything. Head to http://YOUR_IP_ADDRESS/nextcloud/ and you will be facing the following screen:

Select an administrator username and password, then you can select the data folder, but if you don’t know what you’re doing it’s best if you leave it with the default value. Then click on “Storage & Database” to select the database you chose during step 2. Fill everything and if you’ve followed all the steps correctly you should be seeing the Files app:

    I get permission denied on step 3 running wget. I am using Google Cloud Platform. I am not sure whether its folder permission or or what?

    • Hello Skeptic, thank you for choosing my guide to install NextCloud 12. Indeed it is a permission you’re lacking. Are you executing these commands as privileged user? (or as root?). You can become a privileged user by prefixing “sudo” to a command, or if you prefer to become root you can use “sudo su”. Let me know if it works or you need further help : )

  • Puff Face

    Hey, my DB password is now blank. How do i change it? Thx for this tut!

    • Hello Puff Face, if you’re using the root user you can change the password using the mysql_secure_installation script. If you created another user and want to change his password you should refer to MariaDB/MySQL manual since the procedure changes depending on the version. If you want to take the “short route”, you can delete (DROP USER username;) and recreate the user, mind that you will lose the privileges associated with that user.
