Technology | Version | Description |
---|---|---|
Java | 11 | Base programic language |
Gradle | 7.1 | Tool for building the application |
Tomcat | 9.0.75 | Servlet server for application |
MySQL | 8.0.33 | Database server for data persistence |
Node.js | 14.20.1 | JavaScript runtime for New UI |
Git | 2.17.1 | Version control for source code |
1. Scada-LTS Installation using standalone installer ↑↑↑
1.1 Go to /~https://github.com/SCADA-LTS/linux-installer and select releases tab and then download latest release to desired folder.
1.2. Go to location of downloaded installer and extract it.
1.3. Start first script by using terminal and typing ./mysql_start.sh
Script will ask for some basic information to make configuration run correctly. Below is an example of the data that can be entered:
- Port: 3306
- Username: admin
- Password: admin
- root password: root
After providing the information you should wait for the line confirming the correct operation of the database:
~/linux-installer-1.2.0/mysql/server/bin/mysqld: ready for connections. Version: '8.0.33' socket: '/tmp/mysql.sock' port: 3306 MySQL Community Server - GPL.
1.4. Start second terminal and run ./tomcat_start.sh
script.
Similar to first script you will have to provide some information, example below:
- Enter port: 8080
- Enter username: root
- enter password: root
- enter database port: 3306 (same as one you provided while configurating database)
- enter database username: admin
- enter database password: admin
After that you should be able to access Scada-LTS via web browser by typing in search bar localhost:8080/Scada-LTS
2. Enviromental variables ↑↑↑
You will have to add PATH for Java and Catalina in ~/.bashrc
file using any available text editor e.g.:
-
nano ~/.bashrc
orvim ~/.bashrc
On the bottom of this text file add two lines from below:
export CATALINA_HOME="/absolute_path_to_installer/linux-installer-1.2.0/tomcat64/server"
export JAVA_HOME="/absolute_path_to_installer/linux-installer-1.2.0/java/jdk"
After all that type in terminal:
source ~/.bashrc
This will reload Enviromental variables.
3. Node.js ↑↑↑
First, you will need nvm
which is Node Version Manager. You can install it running this command in terminal:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
You can check if nvm has installed correctly by typing:
nvm --verison
When everything went succesfull we can install chosen version of Node.js with command below:
nvm install v14.20.1
To make sure that correct version of node is installed type:
node --version
NOTE: If you want to uninstall node or change version of it, you have to use nvm from now on.
4. IntelliJ ↑↑↑
5.1. Download desired version of IntelliJ (Ultimate or Community).
5.2. Put it in freshly made folder and extract it.
5.3. Go inside extracted folder, then to bin
folder and run ./idea.sh
script.
5.4. Install git with command below:
sudo apt-get install git-all
You can confirm if git setup finished correctly by running git version
.
This should open your IntelliJ and make it ready to use.
5. Docker-compose ↑↑↑
To check if you have any version of docker installed, run command from below in terminal.
dpkg -l | grep -i docker
First, we start with commands below to update the apt
package index:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
Run these commands to add docker’s official GPG key:
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
Use command below to set up repository:
echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
Than, we install Docker engine and all necessary docker plugins.
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
After that we install docker-compose itself with command below:
sudo apt install docker-compose
To add non-admin user to docker group use command below:
sudo usermod -aG docker user_name
Where user_name
is the username of user you want to be able to launch docker.
To launch Scada-LTS via docker-compose you will have to download docker-compose.yml to desired folder.
Than go inside docker-compose.yml location using terminal and run:
docker-compose up database
And in second terminal and same location:
docker-compose up scadalts
NOTE: You have to wait for
docker-compose up database
to finish, otherwise errors may appear.
To uninstall all files related to docker use these two commands below:
sudo apt-get purge -y `dpkg-query -W -f='${binary:Package}\t' '*docker*'`
sudo apt-get autoremove -y --purge `dpkg-query -W -f='${binary:Package}\t' '*docker*'`
To delete all files that docker created e.g. groups, sockets etc. use commands below:
sudo rm -rf /var/lib/docker /etc/docker
sudo rm /etc/apparmor.d/docker
sudo groupdel docker
sudo rm -rf /var/run/docker.sock
sudo rm /etc/apt/keyrings/docker.gpg
If you deleted everything correctly command below should return nothing.
dpkg -l | grep -i docker
6. jSerialComm Configuration ↑↑↑
More information about jSerialComm: https://fazecast.github.io/jSerialComm/
However, on linux system configuration is necessary as long as we are not running on root:
sudo usermod -a -G uucp username
sudo usermod -a -G dialout username
sudo usermod -a -G lock username
sudo usermod -a -G tty username

- Current technology stack table
- Tools Installation
- Scada-LTS project initialization
- Integrated Developmnet Environments (IDEs)
- Quick install - Linux Ubuntu 20.04+
Technology | Version | Description |
---|---|---|
Java | 11 | Base programic language |
Gradle | 7.1 | Tool for building the application |
Tomcat | 9.0.41 | Servlet server for application |
MySQL | 5.7 | Database server for data persistence |
Node.js | 14.20.1 | JavaScript runtime for New UI |
Git | 2.17.1 | Version control for source code |
The base project is written in Java. So to start development a new features to Scada-LTS you need to install Java Development Kit (JDK). You can do that easily by downloading the valid version from the jdk.java.net website. Then you only need to extract that file and set-up the PATH variable to /bin directory.
- For windows download dedicated Windowsx64.zip version.
- Extract that file in location where you want to keep your Java binaries
(for example C:\services\java\jdk-11) - Set-up the PATH environment variable to bin directory of your installation location
(for example C:\services\java\jdk-11\bin) - Verify that Java is installed correctly, open your terminal and type
java -version
- For Linux base systems download Linux_x64.tar.gz
- Create a directory
sudo mkdir /opt/java
- Extract archive to that directory
(for example:sudo tar -xzf openjdk-11*.tar.gz -C /opt/java/
) - Set-up the PATH environment variable to bin directory of you installation location
(for examplenano ~/.bashrc
and then add at the bottom of that file this lines and save it)
export JAVA_HOME=/opt/java/jdk-11
export PATH=$JAVA_HOME/bin:$PATH
- Verify that Java is installed correctly, open your terminal and type
java -version
Gradle is a general-purpose build tool that makes taht the build process is very simple. Installation of gradle is well described on their official web page. So follow the tutorial and then verify that gradle is installed:
gradle -v
Support Gradle v6.8.1-v7.1
Tomcat is an servlet web-application server.
-
Download the Tomcat server from their official distribution page
(If you want to download a specific version use that link to dist archive) -
Extract that file to specific location
- Windows: like in our example to
C:\services\tomcat
- Linux: in the same way as before but to
/opt/tomcat
- Windows: like in our example to
-
Set-up the new environment variable with name:
CATALINA_HOME
that is a reference to tomcat main directory.
(That is required to perform Java build operation) -
Import additional Tomcat server libraries:
- Add that file to
/usr/share/tomcat9/lib/
directory. - Add files from that directory to tomcat
/usr/share/tomcat9/lib/
libs.
- Add that file to
-
Setup the Database connection in
$CATALINA_HOME\conf\context.xml
file.
Replace it with that configuration fileFrom version 2.6.10 there's change in context.xml to work with Docker Compose, so after coping this file to Tomcat, change line:
url="jdbc:mysql://database:3306/scadalts"
tourl="jdbc:mysql://localhost:3306/scadalts"
MySQL must be matching the provided version. If not there will be a problem with establishing the connection from the Scada-LTS application.
- Use dedicated installer
- Configure default password to "root" user: "root".
- Create a new database with name: "scadalts".
There is a know bug that on Ubuntu 20.xx there is a problem with installing the MySQL server. It was solved by using the docker image with that server version.
- Install mysql-server package
sudo apt update sudo apt install mysql-server-5.7
- Configure MySQL server with defaulr password to "root" user: "root".
sudo mysql_secure_installation
- Initialize MySQL data directory
- Versions < 5.7.6 -
mysql_install_db
- Versions >= 5.7.6 -
mysqld --initialize
- Versions < 5.7.6 -
- Enable MySQL server
sudo systemctl start mysql
- Create a new database with name: "scadalts".
If there is a problem with MySQL server check the Internet for the solution. This installation process was based on the digitalOcean tutorial so check it for more details.
- Download the Long Term Support (LTS) version of Node.js from official site.
- Extract that file to specific location
- Windows: like in our example to
C:\services\node
- Linux: in the same way as before but to
/opt/node
- Windows: like in our example to
- Add a new entry to
PATH
that is a reference to Node.js main directory.
(/opt/node/node-v15/bin:$PATH) - Verify that Node.js is installed correctly, open your terminal and type
node -v
- Verify that Node Package Manager (npm) was installed with Node.js correctly.
Open your terminal and typenpm -v
Linux has installation of git by default. So you don't need to install it, but on Windows you need to download it from official site. The easiest way to install git is to use the installer.
Find a good place on your local drive where to store your Scada-LTS project. And in that place use Git Tool to download it from the GitHub repository.
git clone /~https://github.com/SCADA-LTS/Scada-LTS.git
Now you should be able to build and run the project using Gradle (support v6.8.1-v7.1). That command will build the Java application from source code and then will try to compile the Frontend apllication with installing all necessary dependencies. Then that two projects will be bundled together into the one Scada-LTS.war
file that will be deployed to the Tomcat server.
gradle buildRunDebugDev
When it will be ready you should be able to access to the application at the following address: localhost:8080/ScadaBR
.
It's up to you to choose the IDE that you want to use. But we recommend to use the JetBrains IntelliJ for the base Java application and VisualStudio Code for the Frontend sub-project. But you can use any other IDE that you want.
