#Step 1. Install NGINX
sudo apt-get update -y
sudo apt-get install nginx -y
sudo systemctl stop nginx.service 
sudo systemctl start nginx.service 
sudo systemctl enable nginx.service

#Step 2. Install MariaDB/MySQL
#Run the following commands to install MariaDB database for Moode. You may also use MySQL instead.
sudo apt-get install mariadb-server mariadb-client -y

#Like NGINX, we will run the following commands to enable MariaDB to autostart during reboot, and also start now.
sudo systemctl stop mysql.service 
sudo systemctl start mysql.service 
sudo systemctl enable mysql.service

#Run the following command to secure MariaDB installation.
#password mysql mariadb , i'm fixed: M@tKh@uS3cr3t  --> you must changit. 

sudo mysql_secure_installation  <<EOF

#You will see the following prompts asking to allow/disallow different type of logins. Enter Y as shown.
# Enter current password for root (enter for none): Just press the Enter
# Set root password? [Y/n]: Y
# New password: Enter password
# Re-enter new password: Repeat password
# Remove anonymous users? [Y/n]: Y
# Disallow root login remotely? [Y/n]: N
# Remove test database and access to it? [Y/n]:  Y
# Reload privilege tables now? [Y/n]:  Y
# After you enter response for these questions, your MariaDB installation will be secured.

#Step 3. Install PHP-FPM & Related modules
sudo apt-get install software-properties-common -y
sudo -S add-apt-repository ppa:ondrej/php -y
sudo apt update -y

#sudo git ITIL clone https://github.com/glpi-project/glpi/releases/download/$GitGLPIversion/glpi-$GitGLPIversion.tgz
#Change directory into the downloaded ITIL folder
#Uncompress the downloaded the archive:
tar xvf glpi-$GitGLPIversion.tgz

cd glpi
#Retrieve a list of each branch available 
#sudo git branch -a
#Tell git which branch to track or use
#sudo git branch --track $GitGLPIversion origin/$GitGLPIversion

#if get error
git fetch
#Finally, Check out the ITIL version specified 
sudo git checkout $GitGLPIversion
#Run the following command to extract package to NGINX website root folder.
sudo cp -R /opt/glpi /var/www/html/$FQDN
sudo mkdir /var/www/html/$FOLDERDATA
#Change the folder permissions.
sudo chown -R www-data:www-data /var/www/html/$FQDN/

#Accept License terms and click “Continue“.
#Choose ‘Install‘ for a completely new installation of GLPI.
#Confirm that the Checks for the compatibility of your environment with the execution of GLPI is successful.
#Configure Database connection
#Select glpi database to initialize.
#Finish the other setup steps to start using GLPI.
#You should get the login page.
#Default logins / passwords are:
#    glpi/glpi for the administrator account
#    tech/tech for the technician account
#    normal/normal for the normal account
#    post-only/postonly for the postonly account
# On first login, you’re asked to change the password. Please set new password before configuring GLPI. This is done under Administration > Users.
