# This is the endboard software, it is a textboard written for the use 
# in the darknets.
#
# This is the installation script, which you can use to make the needed
# directories and distribute the files.
# 
# The writing of this code started some time ago with another software 
# called smolBBS. Although there is almost no original code left now, 
# I still regard endboard as a fork of smolBBS.
# The author of smolBBS has required that the following text be

### Make directories
function make_directories
{
mkdir -p /srv/endboard/mob /etc/opt/endboard /var/opt/endboard /opt/endboard
chown -R www-data:www-data /var/opt/endboard
}

### Distribute files to directories (from directory of the endboard archive):
function distribute_files
{
cp -rv ./srv/* /srv/endboard/
cp -v ./opt/*.php /opt/endboard/
}

### Distribute config files (from directory of the endboard archive):
function distribute_config_files
{
cp -v ./etc/config.php /etc/opt/endboard/
cp ./etc/endboard /etc/nginx/sites-available/
}

### Enable the site in nginx config dirs
function enable_site
{
ln -s /etc/nginx/sites-available/endboard /etc/nginx/sites-enabled/
nginx -t && systemctl reload nginx
}

### Show some help text to explain what we do here
function show_help
{
echo "This is a little script to automate the installation process."
echo "The first step is always to update your system and install "
echo "all the needed components. On a debian system, it would be done "
echo "like this:"
echo
echo "apt update "
echo "apt upgrade -y "
echo "apt install -y php php-json php-mbstring php-sqlite3 php-fpm nginx"
echo
echo "After that, edit the files etc/config.php and etc/endboard "
echo "according to your needs."
echo
echo "After these steps, you can use the script like this"
echo
echo "./install.sh dirs : make all needed directories (standard paths)"
echo "./install.sh files : distribute files to directories"
echo "./install.sh config : distribute config files (endboard & nginx)"
echo "./install.sh enable : enable the site and restart nginx"
echo "./install.sh all : do all of the above in sequence" 
}
