==================================================

>>> EINMALIG - Vorbereitung manuelle Installation <<<

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*** Raspberry Pi updaten ***

sudo apt update && sudo apt upgrade -y
sudo apt full-upgrade -y

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*** EINMALIG - Installation libwebsockets *** (Stand 24.04.2022)

# CMake installieren, wenn noch nicht vorhanden
sudo apt install cmake -y
# Version prüfen
cmake --version

# libwebsockets-Repository klonen und im Ordner /usr/src/ ablegen
cd /usr/src/
ls -lh
# Falls Verzeichnis vorhanden, zuerst löschen
sudo rm -d -r /usr/src/libwebsockets
ls -lh
sudo git clone https://libwebsockets.org/repo/libwebsockets
ls -lh

# libwebsockets zusammenbauen und installieren
cd /usr/src/libwebsockets
# optional, in 'main' scheinen immer die neuesten Fixes drin zu sein, bis sie dann nach 'master' kommen.
#git checkout main
sudo mkdir build
cd build
sudo cmake ..
sudo make
sudo make install

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*** EINMALIG - Installation MariaDB *** (Stand 24.04.2022)

# MariaDB installieren
sudo apt install mariadb-server

# MariaDB root-Kennwort vergeben
# MariaDB fragt unter Raspberry Pi OS bei der Installation leider
# nicht nach einem Kennwort für den Benutzer root.
# Dieses muss man erst setzen. Dies geht wie folgt.
# https://canox.net/2017/08/passwort-fuer-den-root-benutzer-von-mariadb-setzen/

# MariaDB Secure Konfiguration
# https://mariadb.com/kb/en/library/mysql_secure_installation/
sudo mysql_secure_installation
#Enter current password for root (enter for none):
<MariaDBrootPasswort>
#OK, successfully used password, moving on...
#
#Setting the root password or using the unix_socket ensures that nobody
#can log into the MariaDB root user without the proper authorisation.#
#
#You already have your root account protected, so you can safely answer 'n'.
#
#Switch to unix_socket authentication [Y/n]
n
#... skipping.
#
#You already have your root account protected, so you can safely answer 'n'.
#
#Change the root password? [Y/n]
n
#... skipping.
#
#By default, a MariaDB installation has an anonymous user, allowing anyone
#to log into MariaDB without having to have a user account created for
#them.  This is intended only for testing, and to make the installation
#go a bit smoother.  You should remove them before moving into a
#production environment.
#
#Remove anonymous users? [Y/n]
y
#... Success!
#
#Normally, root should only be allowed to connect from 'localhost'.  This
#ensures that someone cannot guess at the root password from the network.
#
#Disallow root login remotely? [Y/n]
y
#... Success!
#
#By default, MariaDB comes with a database named 'test' that anyone can
#access.  This is also intended only for testing, and should be removed
#before moving into a production environment.
#
#Remove test database and access to it? [Y/n]
y
#- Dropping test database...
# ... Success!
# - Removing privileges on test database...
# ... Success!
#
#Reloading the privilege tables will ensure that all changes made so far
#will take effect immediately.
#
#Reload privilege tables now? [Y/n]
y
#... Success!
#
#Cleaning up...
#
#All done!  If you've completed all of the above steps, your MariaDB
#installation should now be secure.
#
#Thanks for using MariaDB!

~~~~~~~~~~~~~~~~~~~~~~~~~

# Setup lokale Datenbank
sudo mysql -u root -Dmysql -p
#Enter password:
<MariaDBrootPasswort>
MariaDB [mysql]> CREATE DATABASE p4 charset utf8;
MariaDB [mysql]> CREATE USER 'p4'@'localhost' IDENTIFIED BY 'p4';
MariaDB [mysql]> GRANT ALL PRIVILEGES ON p4.* TO 'p4'@'localhost' IDENTIFIED BY 'p4';
MariaDB [mysql]> flush privileges;
MariaDB [mysql]> exit

*** Raspberry Pi updaten ***

sudo apt update && sudo apt upgrade -y
sudo apt full-upgrade -y

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*** EINMALIG - Build-Abhängigkeiten installieren *** (Stand 24.04.2022)

# p4d zusammenbauen und installieren
cd /usr/src/linux-p4d
sudo make clean all

# p4d installieren, nur falls notwendig!
# ACHTUNG!!!
# Wenn danach ein p4d-Paket gebaut wird, "make install" NICHT ausführen!
# p4d wird später mit dem gebauten Paket installiert.
#sudo make install

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*** Erster Start des p4d Daemon *** (Stand 24.04.2022)

# ACHTUNG!!!
# Wenn vorher "make install" NICHT ausgeführt wurde,
# dann wird dieser Block nicht benötigt!
# p4d wird später mit dem gebauten Paket gestartet.

# p4d starten
#sudo systemctl start p4d

# Status p4d prüfen
# it should now 'enabled' and in state 'running'!

# Wichtig!
# Anpassung für Raspberry Pi OS (64-bit) notwendig!
# In ../contrib/DEBIAN/control steht aktuell "Architecture: armhf" (ohne ")
# Muss ersetzt werden durch "Architecture: arm64" (ohne ")
# ...Entweder manuell ersetzen
#sudo nano /usr/src/linux-p4d/contrib/DEBIAN/control
# ...Oder automatisch ersetzen
sudo sed -i 's/Architecture: armhf/Architecture: arm64/g' /usr/src/linux-p4d/contrib/DEBIAN/control
