Manual installation ¶

Deployment of the system consists of several steps. They are numbered for ease of verification. Perform all steps one by one.

1. Preparing the environment¶

To run and run the system, you need a Docker container in which to load the image with all the necessary dependencies. Therefore, the first thing you must do is install the docker and docker-compose packages and unzip on the virtual machine:

sudo apt -y update && apt install docker.io docker-compose unzip

2. Downloading an image¶

Next, create a directory /opt/getscreen, in which the system image will be downloaded and unpacked. Run the following commands:

sudo docker login updater.getscreen.me:5000

sudo mkdir -p /opt/getscreen
sudo chown $USER /opt/getscreen
cd /opt/getscreen
wget --user=<login> --ask-password https://updater.getscreen.me:5000/install/getscreen.zip
unzip getscreen.zip

3. Obtaining a certificate¶

A self-signed SSL certificate is included in the standard delivery of the system. It can be found in the following files:

To ensure that browsers do not generate warnings about insecure connections, you must obtain a full-fledged certificate. This can be purchased from a certificate authority, or allocated for free from Let's Encrypt .

3.1 Obtaining a Let's Encrypt certificate¶

Run the following commands, replacing <hostname> with your domain name. During execution, follow the instructions the system gives you. Access to your domain's DNS server will be required.

sudo apt -y install certbot
sudo certbot certonly --standalone -d <hostname>

After completing all the actions, the files of the obtained certificate will lie in the following directories:

Copy these files to the /opt/getscreen/cert/ directory by running the following commands:

sudo cp --copy-contents /etc/letsencrypt/live/<hostname>/fullchain.pem /opt/getscreen/cert/server.crt
sudo cp --copy-contents /etc/letsencrypt/live/<hostname>/privkey.pem /opt/getscreen/cert/server.key

4. Setup configurations¶

4.1 Password to the database¶

Think of and specify your database password in the docker-compose.yml, server/config.json, download/config.json and download/config.json files.

You need to replace the line changeme-sql-pass with your password.

In the file docker-compose.yml:

#########################################################
# Database server
#########################################################

db:
image: docker.io/postgres:14
container_name: getscreen-db
restart: always
environment:
    - POSTGRES_DB=getscreen
    - POSTGRES_USER=getscreen
    - POSTGRES_PASSWORD=changeme-sql-pass
volumes:
    - ./db/data:/var/lib/postgresql/data
ports:
    - 127.0.0.1:5000:5432

In the file server/config.json:

    "sql": {
      "server": "127.0.0.1",
      "port": 5000,
      "user": "getscreen",
      "password": "changeme-sql-pass",
      "log": false
    },

In the file download/config.json:

    "sql": {
        "db": "getscreen",
        "host": "127.0.0.1",
        "user": "getscreen",
        "port": 5000,
        "ssl": false,
        "password": "changeme-sql-pass"
    },

4.2 IP address¶

Replace in server/config.json file all lines with IP addresses 11.22.33.44 with <your-ip>, where:

• <your-ip> is the public IP address of your server.

4.3 Domain name¶

Replace all lines of getscreen.test with <your-domain> where <your-domain> is your domain name in the following files:

• server/config.json.
• download/config.json.
• storage/config.json.

4.4 SMTP server¶

Specify your mail server settings in the mail section:

    "mail": {
        "user": "robot@getscreen.test",
        "password": "changeme-mail-password",
        "server": "smtp.mailserver.com",
        "port": 465,
        "email": "robot@getscreen.test"
    },

4.5. Tokens and keys for components¶

To pair all the components of the system with each other and with the main server, it is necessary to prescribe in their configurations the appropriate keys and tokens. For convenience, all the keys are collected in the table below. You need to replace the key identifier in the corresponding files with a value with a random set of characters of a given length.

5. Launching the system¶

To start the system, run the following commands:

cd /opt/getscreen
sudo docker-compose up -d

6. Error Checking¶

Check the main server and component logs for errors. The log files are stored in the following paths:

/opt/getscreen/server/log/*.log
/opt/getscreen/download/log/*.log
/opt/getscreen/image/log/*.log
/opt/getscreen/proxy/log/*.log
/opt/getscreen/storage/log/*.log

If there are errors, they will tell you the procedure to correct them.

7. Checking web server availability¶

Open your browser and go to https://<your-ip>, where:

• <your-ip> is the public IP address of the server

The license activation page should open.

8. License Activation¶

After starting the system, the master web server will display the license activation page. Enter the license key that is supplied with the system and the domain name you selected for the server - the one for which you allocated the certificate in step 3.

After checking the key, the system will automatically put the license file in the path /opt/getscreen/server/license.lic and offer to restart the server. To restart, run the command:

sudo docker container restart getscreen-server

After restarting, your license will be activated and the web server will give you the login page by domain.

The default administrator account:

login: administrator
password: Getscreen
