Installation and configuration of Dspace + Solr + Joomla

Complete installation and configuration of Dspace with Solr, and integration with Joomla on Linux. The Linux server is Debian and will be configured in the main functions for the installation of Dspace. The installation and compilation of the software that are the requirements (Tomcat, PosgreSQL, Maven, Ant, several libs, etc) affect the installation of Dspace, and therefore must be done together. This installation has already been tried but the Dspace frontend did not activate, including using docker. Solr must be configured to retrieve data from 2 local sites and 1 far site. The local site is Joomla and another one in MYSQL. The remote site is WordPress. Of all, Solr must obtain the data to deliver to Dspace, in addition to the files available in the various folders on the server. Also, Joomla needs to access and get search results directly from Solr using PHP libraries. Requires solid knowledge of Dspace and Solr, as a backend and installation user. Dspace and Solr are the main platforms of the project.
