Instalar Apache Tomcat

https://tecadmin.net/install-tomcat-9-on-ubuntu/

No olvidar dar los permisos al usuario ubuntu para acceder a las carpetas respectivas:

Step 4: Update Permissions The tomcat user that we set up needs to have access to the Tomcat installation. We'll set that up now.

Change to the directory where we unpacked the Tomcat installation:

cd /opt/tomcat

Give the tomcat group ownership over the entire installation directory:

sudo chgrp -R tomcat /opt/tomcat

Next, give the tomcat group read access to the conf directory and all of its contents, and execute access to the directory itself:

sudo chmod -R g+r conf

sudo chmod g+x conf

Make the tomcat user the owner of the webapps, work, temp, and logs directories:

sudo chown -R tomcat webapps/ work/ temp/ logs/

Now that the proper permissions are set up, we can create a systemd service file to manage the Tomcat process.
