Instructions for setting up new expo debian server/VM
For Debian Stretch, June 2019.

adduser expo
apt install openssh-server mosh tmux mc zile emacs-nox mc most ncdu
apt install python-django apache2 mysql-server survex make rsync 
apt install libjs-openlayers make 
apt install git mercurial mercurial-server?

for boe:
apt install libcgi-session-perl libcrypt-passwdmd5-perl libfile-slurp-perl libgit-wrapper-perl libhtml-template-perl libhtml-template-pro-perl libmime-lite-perl libtext-password-pronounceable-perl libtime-parsedate-perl libuuid-tiny-perl libcrypt-cracklib-perl

obsolete-packages:
 bins (move to jigl?) (for photos)
 python-django 1.7
backports: survex therion
not-packaged: caveview

make these dirs available at top documentroot:
cuccfiles
expofiles
loser  (link to repo)
tunneldata (link to repo)
troggle (link to repo)
expoweb (link to repo)
boc/boe


config
containing:

setup apache configs for cucc and expo
#disable default website
a2dissite 000-default
a2ensite cucc
a2ensite expo
a2enmod cgid


Boe config:
Alias /boe /home/expo/boe/boc/boc.pl
<Directory /home/expo/boe/boc>
        AddHandler cgi-script .pl
        SetHandler cgi-script
        Options +ExecCGI
        Require all granted
</Directory>
And remember to set both program and data dir to be
www-data:www-data
(optionally make file group read/write by treasurer account)
create empty repo by clicking create in boe interface
then set names in 'settings'

Set up mysql (as root)
mysql -p
CREATE DATABASE troggle;
GRANT ALL PRIVILEGES ON troggle.* TO 'expo'@'localhost' IDENTIFIED BY 'somepassword';  

install django:
sudo apt install python-django python-django-registration python-django-imagekit python-django-tinymce fonts-freefont-ttf libapache2-mod-wsgi

python-django-imagekit comes from https://salsa.debian.org/python-team/modules/python-django-imagekit
python-django-tinymce comes from https://salsa.debian.org/python-team/modules/python-django-tinymce
(both modified for stretch/python2). packages under /home/wookey/packages/

need fonts-freefont-ttf (to have truetype freesans available for troggle via PIL)
need libapache2-mod-wsgi for apache wsgi support.

On stretch the django 1.10 is no use so get rid of that:
apt remove python3-django python-django python-django-common python-django-doc

Then replace with django 1.7 (Needs to be built for stretch)
apt install python-django python-django-common python-django-doc
apt install python-django-registration python-django-imagekit python-django-tinymce

then hold them to stop them being upgraded by unattended upgrades:
echo "python-django hold" | sudo dpkg --set-selections
echo "python-django-common hold" | sudo dpkg --set-selections
echo "python-django-doc hold" | sudo dpkg --set-selections

#troggle has to have a writable logfile otherwise the website explodes
# 500 error on the server, and apache error log has non-rentrant errors
create /var/log/troggle/troggle.log
chown www-data:adm  /var/log/troggle/troggle.log
chmod 660 /var/log/troggle/troggle.log
