Installation¶
This installation guide covers the installation of PyScada for Debian 7/8/9 , Raspbian, Fedora 22/23 based Linux systems using MySQL / MariaDB or SQLite as Database, Gunicorn as WSGI HTTP Server and nginx as HTTP Server.
Dependencies¶
Debian 9, Raspbian¶
sudo -i
apt-get update
apt-get -y upgrade
# if you use MariaDB/MySQL as Database system (recommend)
apt-get -y install mariadb-server python3-mysqldb
apt-get install -y python3-pip libhdf5-100 libhdf5-dev python3-dev nginx
pip3 install gunicorn
pip3 install pyserial
pip3 install docutils
macOS¶
- MySQL Server <https://www.mysql.de/>
- HDF5 TODO
brew install python
export PATH=$PATH:/usr/local/mysql/bin
pip install MySQL-python
all¶
sudo -i
pip3 install https://github.com/trombastic/PyScada/archive/dev/0.7.x.zip
# for VISA Protocol
pip3 install pyvisa pyvisa-py
# for 1Wire Protocol
apt-get install owfs #
pip3 install pyownet
# for smbus Protocol, install libffi-dev first!
apt-get install libffi-dev
pip3 install smbus-cffi
Add a new system-user for Pyscada (optional, recommend)¶
Add a dedicated user for the pyscada server instance and add a directory for static/media files.
Linux¶
sudo -i
useradd -r pyscada
mkdir -p /var/www/pyscada/http
chown -R pyscada:pyscada /var/www/pyscada
mkdir -p /home/pyscada
chown -R pyscada:pyscada /home/pyscada
macOS¶
sudo -i
dscl . -create /Users/pyscada IsHidden 1
dscl . -create /Users/pyscada NFSHomeDirectory /Users/pyscada
LastID=`dscl . -list /Users UniqueID | awk '{print $2}' | sort -n | tail -1`
NextID=$((LastID + 1))
dscl . create /Users/pyscada UniqueID $NextID
dscl . create /Users/pyscada PrimaryGroupID 20
mkdir -p /var/www/pyscada/http
chown -R pyscada:staff /var/www/pyscada/
Create a MySql Database¶
Create the Database and grand the nessesery permission. Replace PyScada_db, PyScada-user and PyScada-user-password as you like.
mysql -uroot -p -e "CREATE DATABASE PyScada_db CHARACTER SET utf8;GRANT ALL PRIVILEGES ON PyScada_db.* TO 'PyScada-user'@'localhost' IDENTIFIED BY 'PyScada-user-password';"
Create a new Django Project¶
# Linux/OSX
cd /var/www/pyscada/
sudo -u pyscada django-admin startproject PyScadaServer
see Django Settings for all necessary adjustments to the django settings.py and urls.py.
Initialize Database And Copy Static Files¶
cd /var/www/pyscada/PyScadaServer # linux
sudo -u pyscada python3 manage.py migrate
sudo -u pyscada python3 manage.py collectstatic
# load fixtures with default configuration for chart lin colors and units
sudo -u pyscada python3 manage.py loaddata color
sudo -u pyscada python3 manage.py loaddata units
# initialize the background service system of pyscada
sudo -u pyscada python3 manage.py pyscada_daemon init
Add a Admin User To Your Django Project¶
cd /var/www/pyscada/PyScadaServer
sudo -u pyscada python3 manage.py createsuperuser
Setup the Webserver (nginx, gunicorn)¶
# debian
sudo wget https://raw.githubusercontent.com/trombastic/PyScada/dev/0.7.x/extras/nginx_sample.conf -O /etc/nginx/sites-available/pyscada.conf
# Fedora
sudo wget https://raw.githubusercontent.com/trombastic/PyScada/dev/0.7.x/extras/nginx_sample.conf -O /etc/nginx/conf.d/pyscada.conf
after editing, enable the configuration and restart nginx, optionally remove the default configuration
to use ssl (https, recommend)¶
generate ssl certificates.
# for Debian, Ubuntu, Raspian
sudo mkdir /etc/nginx/ssl
# the certificate will be valid for 5 Years,
sudo openssl req -x509 -nodes -days 1780 -newkey rsa:2048 -keyout /etc/nginx/ssl/pyscada_server.key -out /etc/nginx/ssl/pyscada_server.crt
# debian
sudo ln -s /etc/nginx/sites-available/pyscada.conf /etc/nginx/sites-enabled/
sudo rm /etc/nginx/sites-enabled/default
now it’s time to [re]start nginx.
# systemd (Debian 8, Fedora, Ubuntu > XX.XX)
sudo systemctl enable nginx.service # enable autostart on boot
sudo systemctl restart nginx
# SysV-Init (Debian 7, Ubuntu <= XX.XX, [Debian 8])
sudo service nginx restart
for Fedora you have to allow nginx to serve the static and media folder.
sudo chcon -Rt httpd_sys_content_t /var/www/pyscada/http/
add gunicorn and pyscada unit files:
# systemd
sudo wget https://raw.githubusercontent.com/trombastic/PyScada/dev/0.7.x/extras/service/systemd/gunicorn.socket -O /etc/systemd/system/gunicorn.socket
sudo wget https://raw.githubusercontent.com/trombastic/PyScada/dev/0.7.x/extras/service/systemd/gunicorn.service -O /etc/systemd/system/gunicorn.service
sudo wget https://raw.githubusercontent.com/trombastic/PyScada/dev/0.7.x/extras/service/systemd/pyscada_daemon.service -O /etc/systemd/system/pyscada.service
# in some installations gunicorn is not at /usr/local/bin/gunicorn but at /usr/bin/gunicorn
# in this case you have to change the pat in the file /etc/systemd/system/gunicorn.service accordingly
# enable the services for autostart
sudo systemctl enable gunicorn
sudo systemctl start gunicorn
sudo systemctl enable pyscada
Start PyScada¶
sudo systemctl start pyscada
