This brief tutorial shows students and new users steps to install and configure NextCloud on Ubuntu 16.04 LTS Servers their own environment.
To get started with installing NextCloud, follow the steps below:

sudo apt-get update
sudo apt install apache2 -y

After installing Apache2, run the commands below to disable directory listing.

sudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/apache2/apache2.conf

Next, run the commands below to stop, start and enable Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

Step 2: Install MariaDB

 NextCloud also requires a database server to function.. and MariaDB database server is a great place to start. To install it run the commands below.

sudo apt-get update
sudo apt-get install mariadb-server mariadb-client -y

After installing, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

sudo systemctl stop mysql.service
sudo systemctl start mysql.service
sudo systemctl enable mysql.service

After that, run the commands below to secure MariaDB server.
sudo mysql_secure_installation

  • 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
Restart MariaDB server

sudo systemctl restart mysql.service

Step 3: Install PHP 7.1 And Related Modules

 Run the commands below to add the below third party repository to upgrade to PHP 7.1
