NextCloud

NextCloud is a free open-source self-hosted cloud storage solution. It’s functionally similar to Dropbox. Proprietary cloud storage solutions (Dropbox, Google Drive, etc) are convenient, but at a price: they can be used to collect personal data because your files are stored on their computers. If you worried about privacy, you can switch to NextCloud, which you can install on your private home server or on a virtual private server (VPS). You can upload your files to your server via NextCloud and then sync those files to your desktop computer, laptop or smartphone. This way you have full control of your data.

NextCloud Features

• Free and open-source

• End-to-end encryption, meaning files can be encrypted on client devices before uploaded to the server, so even if someone steals your server, they can not read your files.
• Can be integrated with an online office suite (Collobora Online, OnlyOffice) so you can create and edit your doc, ppt, xls files directly from NextCloud.
• The app store contains hundreds of apps to extend functionality (like calendar app, contacts app, note-taking app, video conferencing app, etc).
• The sync client is available on Linux, macOS, Windows, iOS and android.

Installasi

Download NextCloud on Ubuntu 20.04

Log into your Ubuntu 20.04 server. Then download the NextCloud zip archive onto your server. The latest stable version is 21.0.1 at time of this writing. You may need to change the version number. Go to https://nextcloud.com/install and click the download for server button to see the latest version. You can run the following command to download it on your server.

wget https://download.nextcloud.com/server/releases/nextcloud-21.0.1.zip

You can always use the above URL format to download NextCloud. If a new version comes out, simply replace 21.0.1 with the new version number.

Once downloaded, extract the archive with unzip.

sudo apt install unzip

sudo unzip nextcloud-21.0.1.zip -d /usr/share/nginx/

The -d option specifies the target directory. NextCloud web files will be extracted to /usr/share/nginx/nextcloud/. Then we need to change the owner of this directory to www-data so that the web server (Nginx) can write to this directory.

sudo chown www-data:www-data /usr/share/nginx/nextcloud/ -R

Create a Database and User for Nextcloud in MariaDB Database Server

Log into MariaDB database server with the following command. Since MariaDB is now using unix_socket plugin to authentication user login, there’s no need to enter MariaDB root password. We just need to prefix the mysql command with sudo.

sudo mysql

Then create a database for Nextcloud. This tutorial name the database nextcloud. You can use whatever name you like.

create database nextcloud;

Create the database user. Again, you can use your preferred name for this user. Replace your-password with your preferred password.

create user nextclouduser@localhost identified by 'your-password';

Grant this user all privileges on the nextcloud database.

grant all privileges on nextcloud.* to nextclouduser@localhost identified by 'your-password';

Flush privileges and exit.

flush privileges;

exit;

Create a Nginx Config File for Nextcloud

Create a nextcloud.conf file in /etc/nginx/conf.d/ directory, with a command-line text editor like Nano.

sudo nano /etc/nginx/conf.d/nextcloud.conf

Copy and paste the following text into the file. Replace nextcloud.example.com with your own preferred sub-domain. Don’t forget to create DNS A record for this sub-domain in your DNS zone editor. If you don’t have a real domain name, I recommend going to NameCheap to buy one. The price is low and they give whois privacy protection free for life.

server {
    listen 80;
    listen [::]:80;
    server_name nextcloud.example.com;

        access_log off;
   }
}

Save and close the file. (To save a file in Nano text editor, press Ctrl+O, then press Enter to confirm. To exit, press Ctrl+X.)

Then test Nginx configuration.

sudo nginx -t

If the test is successful, reload Nginx for the changes to take effect.

sudo systemctl reload nginx

Install and Enable PHP Modules
