                 По умолчанию в качестве базы данных используется PostgreSQL. Если вы хотите использовать MySQL вместо PostgreSQL, добавьте две переменные окружения для определения типа и порта базы данных перед тем, как запускать скрипт <b>documentserver-configure.sh</b>:
                 <pre><code>export DB_TYPE=mysql
