Nextcloud on OMV 5

As the title states. This solution is without the use of docker. It is just a straight forward installation of Nextcloud 18.0.3 on OMV 5 using Nginx (php-fpm)  with PHP 7.3 that is already installed and MariaDB as our database server. In order to work on port 80 or port 443, we will have to change the OMV web ports to 8080 and 8443. You can achieve this via “General settings” on the OMV web interface. This guide asumes that Nextcloud will user ports TCP/80 and TCP/443. Everything that is marked RED, needs your attention.

Let’s start with some packages.

apt install mariadb-server php-xml php-cli php-cgi php-mysql php-mbstring php-gd php-curl php-zip wget unzip php-imagick php-intl php-gmp -y

Download nextcloud and place it on folder /var/www

cd /usr/src
wget https://download.nextcloud.com/server/releases/nextcloud-18.0.4.zip
unzip nextcloud-18.0.4.zip
mv nextcloud /var/www/
chown -R www-data:www-data /var/www/nextcloud/
chmod -R 755 /var/www/nextcloud/

Now, we have to create a new pool on the fpm, in order to adjust php settings for nextcloud and not mess up the OMV web part.

nano /etc/php/7.3/fpm/pool.d/nextcloud.conf

[nextcloud]
user = www-data
group = www-data

listen = /run/php/php7.3-fpm-nextcloud.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0600

pm = dynamic
pm.max_children = 120
pm.start_servers = 12
pm.min_spare_servers = 6
pm.max_spare_servers = 18
chdir = /

php_value[include_path] = ".:/usr/share/php:/var/www/nextcloud"
php_value[upload_max_filesize] = 512M
php_value[post_max_size] = 512M
php_value[max_execution_time] = 300
php_value[date.timezone] = Europe/Athens
php_value[expose_php] = Off
php_value[memory_limit] = 512M

env[PATH] = /usr/local/bin:/usr/bin:/bin

To improve performance we have to enable opcache and use redis

nano /etc/php/7.3/fpm/conf.d/10-opcache.ini

configuration for php opcache module
; priority=10
zend_extension=opcache.so

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

Install redis and make changes to config.php.

apt-get install redis-server php-redis
systemctl start redis-server
systemctl enable redis-server

nano /var/www/nextcloud/config/config.php

 'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' =>
array(
'host' => 'localhost',
'port' => '6379',
),

Set up our database.

systemctl enable mariadb

mysql_secure_installation

mysql -u root -p

CREATE DATABASE nextclouddb;
CREATE USER 'nextclouduser'@'localhost' IDENTIFIED BY 'changeme';
GRANT ALL ON nextclouddb.* TO 'nextclouduser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Then we have to create a server block from Nginx. This block has SSL enabled so prior to that, you should have SSL certificates created. I point out in bold where changes must be made and also where the SSL certificates should be declared.

nano /etc/nginx/sites-available/nextcloud

server {
    listen [::]:80;
    server_name myserver.mydomain.com;

    # Enforce HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen [::]:443;
    server_name myserver.mydomain.com;

    # Use Mozilla's guidelines for SSL/TLS settings
    # https://mozilla.github.io/server-side-tls/ssl-config-generator/
    ssl_certificate     /etc/ssl/certs/nextcloud.crt;
    ssl_certificate_key /etc/ssl/private/nextcloud.key;

Let’s enable the above block.

cd /etc/nginx/sites-enabled
ln -s ../sites-available/nextcloud nextcloud

For the Nextcloud storage location, I used a folder on my RAID storage. The installation of Nextcloud, asks for data storage path. By default, it places data files inside /var/www/nextcloud. You can skip this step, if you don’t want to change the default storage path.

mkdir /srv/dev-disk-by-id-md-name/cloud
chown www-data:www-data /srv/dev-disk-by-id-md-name/cloud

Restart some services

systemctl restart nginx
systemctl restart php7.3-fpm

Create cron backgroud job

crontab -e -u www-data

Add the following line

*/15 * * * * php -f /var/www/nextcloud/cron.php

Begin the installation on https://yourserveripaddress

On Administration > Basic settings, set background jobs to cron.
