Hardware

Raspberry PI 4 with 4 GB RAM
64GB SD card
Extra storage: Seagate Expansion SSD 1TB
OS: Raspbian

OS

Inserted the SD card in a cardreader connected it my Debian desktop machine and created a partition table with 4 primary partitions:
p116GBW95 FAT32(b)toggled the bootable flag
p216GBLinux(83) 
p316GBLinux(83) 
p4Rest (11,5G)Linux(83) 
https://www.raspberrypi.org/downloads/%20NOOBS/ Downloaded: NOOBS_lite_v3_6.zip 

sudo mkfs.fat -F 32 /dev/mmcblk0p1
sudo mount /dev/mmcblk0p1 /mnt
cd /mnt
sudo unzip ~/Downloads/NOOBS_lite_v3_6.zip
cd
sudo umount /mnt

Boot from SD: Select Raspbian Lite without Desktop ~1 GB

After install system reboots in CLI, login with username: pi and password: raspberry

Change password!

lsblk shows that entire disk is repartitioned

ip addr show

sudo systemctl enable ssh
sudo systemctl start ssh
Use ssh pi@your.ip.address and login with the newly set password. Set IP address fixed in your network configuration. Disconnect keyboard, mouse and screen from the pi it is now remote manageable.

Connect the external harddisk. lsblk told me it was /dev/sda with a single partion of 931.5 GB. Changed the type from ID 7 to 83 (linux). 

sudo mkfs.ext4 /dev/sda1
sudo blkid

Copy the UUID part and create an entry in /etc/fstab like this: 
UUID=da17c338-15a2-453d-b58a-0fc7cad85279  /srv ext4 defaults,errors=remount-ro,noatime 0 1
run: 
mount -a
To see of if all works.

Apache

 

sudo apt-get install apache2
sudo mkdir -p /srv/www/

Enable modules needed by NextCloud: 

sudo a2enmod rewrite headers env dir mime

Create a file called /etc/apache2/sites-available/nextcloud.conf with the following contents: 

Alias /nextcloud "/srv/www/nextcloud/"


  Require all granted
  AllowOverride All
  Options FollowSymLinks MultiViews
  Satisfy Any

  
    Dav off
Enable the new site: 
sudo a2ensite nextcloud.conf
sudo systemctl reload apache2

LATER ENABLE SSL!

MariaDB

 

sudo apt-get install mariadb-server

Adjust /etc/mysql/mariadb.conf.db/50-server.cnf and add the following lines under [server]: 

skip_name_resolve = 1
innodb_buffer_pool_size = 128M
innodb_buffer_pool_instances = 1
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 32M
innodb_max_dirty_pages_pct = 90
query_cache_type = 1
query_cache_limit = 2M
query_cache_min_res_unit = 2k
query_cache_size = 64M
tmp_table_size= 64M
max_heap_table_size= 64M
slow_query_log = 1
slow_query_log_file = /var/log/mysql/slow.log
long_query_time = 1
Add under [mysqld]: 
transaction_isolation = READ-COMMITTED
binlog_format = ROW
innodb_large_prefix=on
innodb_file_format=barracuda
innodb_file_per_table=1

Run: 

grep -r ^socket /etc/mysql/*
and note the location and name of the socket. You need this to configure PHP later on.

PHP

 

sudo apt-get install php php-bz2 php-curl php-gd php-intl php-json php-mbstring php-mysql php-xml php-zip

Adjust /etc/php/7.3/apache2/php.ini. Under [Pdo_mysql] set the socket path and name you noted in the mariadb config, something like: 

pdo_mysql.default_socket=/run/mysqld/mysqld.sock
and add after the line: 
pdo_mysql.allow_local_infile=On
pdo_mysql.allow_persistent=On
pdo_mysql.cache_size=2000
pdo_mysql.max_persistent=-1
pdo_mysql.max_links=-1
pdo_mysql.default_port=
pdo_mysql.default_host=
pdo_mysql.default_user=
pdo_mysql.default_password=
pdo_mysql.connect_timeout=60
pdo_mysql.trace_mode=Off

Now we need to create a database and a database user: 

sudo mysql

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
CREATE DATABASE IF NOT EXISTS nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
GRANT ALL PRIVILEGES on nextcloud.* to 'username'@'localhost';
FLUSH privileges;
quit;

NextCloud

 

cd /srv
sudo curl https://download.nextcloud.com/server/releases/nextcloud-21.0.1.zip -o nextcloud-21.0.1.zip
cd /srv/www/
sudo unzip /srv/nextcloud-21.0.1.zip
sudo chown -R www-data:www-data /srv/www/nextcloud/

goto the http://ip.of.ser.ver/nextcloud/
Fill in an admin name and password, your choice will be configured, so make sure you remember them!
Fill in the database details.
