Nextcloud is like Dropbox, except that you host, control and own your data. Nextcloud is one of the most amazing open source software available out there. It can do a lot of things. A few of my favourites are:

File hosting (Images, Videos)

File syncing

Auto upload of images/videos from your devices

Contacts

Calendars

Tasks

Notes

Talk

And the list goes on. You can find out all the features you can have on Nextcloud HERE. Long story short: Nextcloud is amazing.

And this blog post is about setting up Nextcloud on your own server. I will be using a Digital Ocean Droplet with Ubuntu 16.04.

If you are looking for a cloud provider, I recommend Digital Ocean. They are simply amazing and cheap. You get a 1vCPU, 1GB ram cloud server for just 5$/month. Use my referral link and you will get 10$ and it might help me run this blog for free, without any ads. :)

Let's get started.

Setting up Nginx

We will be using Nginx as our web server. Let's go ahead and install it

sudo apt-get update sudo apt install nginx

Once nginx is installed, start it using

sudo systemctl restart nginx

If everything went, nginx should be up and running. You can verify that by visiting your VPS's public IP in a browser. You can find out your server's public ip by using the following

curl ifconfig.co

Setting up SSL using Let's Encrypt

We need to make sure that all our traffic from the web browser to the Nextcloud server is encrypted using SSL. Let's encrypt is an amazing yet free way to get SSL certificates.

sudo apt install letsencrypt

We'll be using a domain that points to the nextcloud instance you just setup. If you have a domain named example.com , then we'll be using cloud.example.com for the Nextcloud instance. In the following examples, I will be using cloud.example.com and you should replace it with the domain name you will be using

Next, we will be adding a configuration that is exclusive to Let's encrypt.

Create a file /etc/nginx/snippets/letsencrypt.conf with the following content. You can use your editor of choice.

If you are not familiar with any command line text editors, I recommend you use nano.

sudo nano /etc/nginx/snippets/letsencrypt.conf

Paste the following

location ^~ /.well-known/acme-challenge/ { default_type "text/plain"; root /var/www/letsencrypt; }

Then, press Ctrl+X and then Y and press enter. This file will let Let's Encrypt verify your domain without causing any issues when you redirect all http traffic to https.

We need to create the directory /var/www/letsencrypt manually too.

sudo mkdir /var/www/letsencrypt

Next, we need to configure our nginx server.

Create the file /etc/nginx/sites-enabled/nextcloud with the following content

server { listen 80; listen [::]:80; server_name cloud.example.com; include /etc/nginx/snippets/letsencrypt.conf; # enforce https return 301 https://$server_name$request_uri; }

Don't forget to replace cloud.example.com with your domain for nextcloud.

Retrieving the SSL certificates

We have the webserver setup ready for us to retrieve the SSL certificates. Let's go ahead and do that.

Run the following as root

Again, don't forget to use the correct domain name. Also, give a valid email address. This will be used for alerts regarding renewals and in case you lose your certificates.

sudo letsencrypt certonly --email [email protected] --agree-tos -a webroot --webroot-path=/var/www/letsencrypt/ -d cloud.example.com

Once that is done, if everything went fine, you should see a message saying that it successfully retrieved the certificates.

Let's encrypt certificates are valid for 90 days only and should be renewed before they expire. Luckily, when we install letsencrypt package, it adds a cron to renew the certificates. But, we'll need to reload nginx after the new certificates are retrieved. Let's add a cron to do that.

Create a file /etc/cron.d/reload-nginx with the following content

30 2 1 * * root /bin/systemctl reload nginx > /dev/null 2>&1

This will reload the nginx configuration every month so that it will use the newly fetched certificates.

Final Nginx configuration

As of now, we have only installed Nginx, but we did not configure it.

Edi the file /etc/nginx/sites-enabled/nextcloud and paste the following. In one of the previous step, we added a server block in the same file, please note that the same is present in the following snippet. So, you can simply delete /etc/nginx/sites-enabled/nextcloud and create it again with the following.

upstream php-handler { server unix:/var/run/php/php7.0-fpm.sock; } server { listen 80; listen [::]:80; server_name cloud.example.com; include /etc/nginx/snippets/letsencrypt.conf; # enforce https return 301 https://$server_name$request_uri; } server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name cloud.example.com; ssl_certificate /etc/letsencrypt/live/cloud.example.com/cert.pem; ssl_certificate_key /etc/letsencrypt/live/cloud.example.com/privkey.pem; # Add headers to serve security related headers # Before enabling Strict-Transport-Security headers please read into this # topic first. # add_header Strict-Transport-Security "max-age=15768000; # includeSubDomains; preload;"; # # WARNING: Only add the preload option once you read about # the consequences in https://hstspreload.org/.

In this snippet, you will have to replace cloud.example.com with your domain name. You can use this single command to do that

sudo sed -i "s/cloud.example.com/cloud.yourdomain.com/g" /etc/nginx/sites-enabled/nextcloud

That's it. We are done with the nginx configuration. Please note that, nginx won't start now because we haven't installed php yet.

Installing and configuring the database for Nextcloud

Nextcloud needs a database server to store the configurations and whatnot. We will be using mariadb which is a fork of mysql

sudo apt install mariadb-server mariadb-client

This will install the database server and the client tool. Right now, the server does not have a password set. Let's fix that

sudo mysql_secure_installation

This will ask you few questions. Answer them as follows

Enter current password for root (enter for none): <Enter> Set root password? [Y/n]: Y New password: <super-strong-mariadb-root-password> Re-enter new password: <super-strong-mariadb-root-password> Remove anonymous users? [Y/n]: Y Disallow root login remotely? [Y/n]: Y Remove test database and access to it? [Y/n]: Y Reload privilege tables now? [Y/n]: Y

Make sure you replace super-strong-mariadb-root-password with an actual, strong password.

Now, create a new file /root/.my.cnf with the following content

[client] user=root password=super-strong-mariadb-root-password

This way, you don't have to enter the mariadb root password every time you want to access the database console.

Restart the database server

sudo systemctl restart mysql.service

Create the database and user for nextcloud

If you are logged in as the root user, type mysql and press enter to get to the mariadb console. If you are not root, you can use mysql -u root -p and then enter the mysql root password.

We will be creating a database and a database user for our Nextcloud installation

Do as follows. Replace strong_password with an actual, strong password.

MariaDB [(none)]> create database nextcloud; MariaDB [(none)]> CREATE USER 'nextcloud'@'localhost' IDENTIFIED BY 'strong_password'; MariaDB [(none)]> GRANT ALL ON nextcloud.* TO 'nextcloud'@'localhost' IDENTIFIED BY 'strong_password' WITH GRANT OPTION; MariaDB [(none)]> FLUSH PRIVILEGES;

Keep note of the password you chose there. We will need to update this later when Nextcloud asks us for the password.

Setting up Nextcloud

Nextcloud is written in php. So, we need php to be able to run Nextcloud. Let's install it.

sudo apt install unzip php-fpm php-mbstring php-xmlrpc php-soap php-apcu php-smbclient php-ldap php-redis php-gd php-xml php-intl php-json php-imagick php-mysql php-cli php-mcrypt php-ldap php-zip php-curl

Let's download the latest stable version of Nextcloud. As of now, 13.01 is the latest version.

cd /tmp wget https://download.nextcloud.com/server/releases/nextcloud-13.0.1.zip unzip nextcloud-13.0.1.zip sudo mv nextcloud /var/www/nextcloud sudo chown -R www-data:www-data /var/www/nextcloud

And that's it. As a last step in the configuration, let's restart nginx so that it reloads the configuration and be ready to rock.

sudo systemctl restart nginx

Now, open http://cloud.yourdomain.com in your browser, it should redirect to https://cloud.yourdomain.com

and you should be greeted with the Nextcloud final setup screen. It will ask for the database details. Give it as follows

Database user : nextcloud

Database pasword : The one you set in the previous step (strong_password in my case)

Database name : nextcloud

Click on Finish setup.

That's it. Congratulations. You have successfully installed Nextcloud and is ready to use. If you have a question, leave a comment and I will try to address it as soon as possible :)
