This article describes how to setup a Nextcloud server on your NB2800 router.

Nextcloud is a free and open source cloud hosting software. It lets you easily provide files for and share them with others, and lets you customize your cloud with a lot of tools and additional apps.

All basic preparations made are described in this article: How to set up a NB2800 File Server

If you need instructions on how to set up a LXC Container on NB2800 Routers, you can refer to this page: http://wiki.netmodule.com/app-notes/virtualisation.

Before Nextcloud can be installed, some other programs need to be installed and set up. In the first step, enter

apt-get install nginx mariadb-client mariadb-server php7.0-common php7.0-fpm php7.0-cli php7.0-json php7.0-mysql php7.0-curl php7.0-intl php7.0-mcrypt php-pear php7.0-gd php7.0-zip php7.0-xml php7.0-mbstring php7.0-apcu

Now, the Nextcloud folder is created and given to the correct user:

mkdir -p /var/www/nextcloud
chown -R www-data:www-data /var/www

For setting up PHP, several values in three files have to be edited. First, go to /etc/php/7.0/fpm/pool.d/www.conf and edit the following values (Note: all values described here have to be edited, decommented or added):

/etc/php/7.0/fpm/pool.d/www.conf

user = www-data
group = www-data
listen = /run/php/php7.0-fpm.sock
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

Next, go to /etc/php/7.0/fpm/php.ini and edit these values:

/etc/php/7.0/fpm/php.ini

cgi.fix_pathinfo = 0
opcache.enable = 1
opcache.enable_cli = 1
opcache.memory_consumption = 128
opcache.interned_strings_buffer = 8
opcache.max_accelerated_files = 10000
opcache.revalidate_freq = 1
opcache.save_comments = 1

The last file for configuring PHP is /etc/php/7.0/cli/php.ini:

/etc/php/7.0/cli/php.ini

cgi.fix_pathinfo = 0

Now enter

service php7.0-fpm restart

to restart PHP.

First, you have to finish the MariDB installation:

mysql_secure_installation

Here you have to enter your root password. All other questions can be answered with (Y)es.

Before going on, you need to restart MariaDB:

service mysql restart

Now you have to create a new MariaDB user which is only needed for Nextcloud access. To enter the MariaDB editing shell, enter

mysql -u root -p

First, you have to create a new database for Nextcloud. Here this database is called “nextcloud_db”, but you can name it however you want to:

create database nextcloud_db;

Now create a new MariaDB-user with a password which can access the “nextcloud_db”:

create user 'user'@localhost identified by 'password';

Note that you have to enter your own credentials for 'user' and 'password'.

Now all necessary right have to be granted to this new user:

grant all privileges on nextcloud_db.* to 'user'@localhost;
flush privileges;

Now that everything is set up correctly, you can leave the MariaDB shell:

exit;

Now three lines have to be added to some configuration files:

echo "log-bin = /var/log/mysql/mariadb-bin" >> /etc/mysql/my.cnf
echo "log-bin-index = /var/log/mysql/mariadb-bin.index" >> /etc/mysql/my.cnf
echo "binlog_format = mixed" >> /etc/mysql/my.cnf

Now restart MariaDB again:

service mysql restart

First, go to /etc/nginx/nginx.conf and edit the following three lines:

/etc/nginx/nginx.conf

überprüfen ob user = www-data
überprüfen ob worker_process = auto
in html-Block: server_tokens off

In the next step, the Nginx default page needs to be backuped and stored:

mv /etc/nginx/sites-available/default /etc/nginx/sites-available/default.backup

Now, a new default page needs to be created:

nano /etc/nginx/sites-available/default

This new file has to be filled with this code (All passages that need to be edited are marked in the code):

/etc/nginx/sites-available/default
