GeoServer Install
In this section, we are going to install the Apache Tomcat 9 Servlet Java container, which, by default, will be started on the internal port 8080.
We will also perform several optimizations to:
Correctly set up the Java VM Options, like the available heap memory and the garbage collector options.
Externalize the
GeoServerandGeoWebcachecatalogs in order to allow for further updates without the risk of deleting our datasets.
Note
This is still a basic setup of these components. More details will be provided in sections of the documentation concerning the hardening of the system in a production environment. Nevertheless, you will need to tweak those settings, a bit, in accordance with your current system. For instance, if your machine does not have enough memory, you will need to lower the initial amount of available heap memory. Warnings and notes will be placed below the statements that will require your attention.
Install Apache Tomcat 9 (ref. https://yallalabs.com/linux/ubuntu/how-to-install-apache-tomcat-9-ubuntu-20-04/)
Warning
Apache Tomcat 9 requires Java 8, or newer, to be installed on the server. Check the previous steps, in order to be sure you have OpenJDK 8 correctly installed on your system.
Let’s install Tomcat and edit the default startup script.
sudo apt install tomcat9 -y
sudo vim /etc/systemd/system/tomcat9.service
Edit the startup script with the following content:
