Installation

For proper installation you need to clone project from git.

Note

It service installation assumes running in docker container, all commands below must be executed from /srv directory.

Database creation

All databases for service must be created in accordance with “./luna_lambda/configs/config.conf”.

Postgresql (require version 12.2 or higher)
Oracle (require version Oracle Database Express Edition 21c or higher)

Create all required schemes in postgresql. If database or user is not created yet, one should execute the following commands with “user name” and “database” from the config file (for example, config.conf with “luna” and “luna_lambda”):

psql -U postgres;

create role luna;
ALTER USER luna WITH PASSWORD 'luna';
CREATE DATABASE luna_lambda;
GRANT ALL PRIVILEGES ON DATABASE luna_lambda TO luna;
ALTER ROLE luna WITH LOGIN;

Then launch db_create.py script for tables and primal data creation:

python ./base_scripts/db_create.py

If script was executed without errors, all schemes were created successfully. db_create also creates scripts for further database migration (db_repository folder), without these db migration execution is impossible.

First launch and testing

If all previous actions are executed successfully, server is ready to work. To start server please launch run.py script. While start you can add arguments: server message port, path to config, suffix for log files (for different workers). By default 5210 port is used. Also it possible to run service with config from luna-configurator (see configurator).

Example:

./run.py --port 5210 --config ./configs/myconfig.conf --log_suffix 1

After server is started, testing is recommended. To perform testing execute command

python -m unittest tests.unittests_main

All tests should perform successfully.
