Install GeoServer on Ubuntu 18.04

geoserver-install.sh

#
apt-get install openjdk-8-jre 

# PostgreSQL and PostGIS
apt-get install postgresql postgresql-contrib postgis postgresql-10-postgis-2.4

# Create "geoserver" database
sudo -u postgres createuser -P geoserver
sudo -u postgres createdb -O geoserver geoserver
sudo -u postgres psql -c "CREATE EXTENSION postgis; CREATE EXTENSION postgis_topology;" geoserver

# GeoServer install
apt install unzip
mkdir -p /var/www/geoserver
cd /var/www/geoserver
wget https://netcologne.dl.sourceforge.net/project/geoserver/GeoServer/2.14.1/geoserver-2.14.1-bin.zip
unzip geoserver-2.14.1-bin.zip
mv geoserver-2.14.1/* .
echo "export GEOSERVER_HOME=/var/www/geoserver" >> ~/.profile
. ~/.profile

# GeoServer run
./bin/startup.sh

In the browser open http://localhost:8080/geoserver/web/

How can I install it as a service, so that I don't need to run ./bin/startup.sh command each time?

Well you can create a runnable scipt in init.d as following :

cat >> /etc/init.d/geoserver
# then paste what comes at the end on the comment
# then CTRL + D
chmod +x /etc/init.d/geoserver
update-rc.d geoserver defaults
service geoserver start

And then the content of /etc/init.d/geoserver file :

#!/bin/sh
### BEGIN INIT INFO

# Default-Stop:      0 1 6

How to run geoserver with https protocol , what are the configurations required to setup

You can set up a reverse proxy with a webserver like nginx or caddy. Just make sure to configure CSRF for your domain.

Thank you , i used tomcat and deployed certificates
