Installation on PostgreSQL

When operating in production environments with a large number of cameras and motion detection enabled, we recommend using PostgreSQL as a more productive database.

A simple password is used in the examples, it is desirable to change it!

Running PostgreSQL on the host

To install, use the official instructions from the developer's website https://www.postgresql.org/download/

Quick installation in Debian or Ubuntu:

sudo apt install postgresql-common
sudo sh /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh
sudo apt install postgresql-13 -y

After installation and launch, you need to create a database and a role to connect.

sudo -u postgres psql -c "CREATE DATABASE yucca;"
sudo -u postgres psql -c "CREATE USER yucca WITH PASSWORD 'yucca';"
sudo -u postgres psql -c 'GRANT ALL PRIVILEGES ON DATABASE yucca TO yucca;'

Running PostgreSQL in docker

Launch the official container with the necessary parameters:

docker run -d \
    --name yucca-postgres \
    --net host \
    -e POSTGRES_USER=yucca \
    -e POSTGRES_PASSWORD=yucca \
    -e POSTGRES_DB=yucca \
    postgres:13.4-alpine

Setting up the Yucca connection to the database

Stop the server:

sudo systemctl stop yucca

Specify the type postgres in the parameter database.type, as well as other connection details:

• database.host
• database.name
• database.user
• database.password

example of the final configuration via a file:

[database]
  busy_timeout = 500
  ca_cert_path = "/etc/ssl/certs"
  cache_mode = "shared"
  client_cert_path = ""
  client_key_path = ""
  conn_max_lifetime = "0s"
  host = "127.0.0.1:5432"
  log_queries = false
  max_idle_conn = 2
  max_open_conn = 0
  name = "yucca"
  password = "yucca"
  path = ""
  ssl_mode = "disable"
  type = "postgres"
  user = "yucca"

Start the server:

sudo systemctl start yucca

Upon successful connection, the following messages can be seen in the log:

sudo journalctl -o short --no-pager -n 100 -f -u yucca
