Configuring Environment

  $ bin/elasticsearch-plugin install http://dl.bintray.com/content/imotov/elasticsearch-plugins/org/elasticsearch/elasticsearch-analysis-morphology/5.6.7/elasticsearch-analysis-morphology-5.6.7.zip
  

• Install Apache Tomcat 9.0.x using your preferred method.

• Add the unidata-backend.xml to the application configuration, if you going to add custom modules:

  <Resources className="org.apache.catalina.webresources.StandardRoot">
     <JarResources className="org.apache.catalina.webresources.DirResourceSet"
                   base="/home/alex/Develop/Soft/apache-tomcat-9.0.10/modules"
