Mean this step  vim start.d/ssl.ini # change keyStorePath and keyStorePassword to match your keystrore just optional right incase i just remain with http only. After i skip that step then i just continue with step below right? If yes then i has complete it but when i try open in browser http://ip-address/       it cannot show anything. Is there any step that i miss? Appreciate your guidance.

curl -o webapps/ROOT.war https://netxms.com/download/releases/5.1/nxmc-5.1.4.war # download war file to webapps/ROOT.war, so app will be available at /
java -jar /opt/jetty-home-12.0.17/start.jar # test that it runs

useradd -r -s /sbin/nologin jetty # create user so we don't run it as root
systemctl edit --full --force netxms-web.service # create service, paste sample from bellow
systemctl enable --now netxms-web.service # enable autostart and start immediately

Keychain can be either self-signed or you can import existing certificates.

Or you can just omit https on the jetty side and configure ssl-offloading using any other reverse proxy (nginx, reproxy, etc.)

Anyone can guide for this issue?

Thanks

May i know  vim start.d/ssl.ini # change keyStorePath and keyStorePassword to match your keystrore --> this keyStorePath and keyStorePassword refer to which info?

I'm use ubuntu server 22.

Thanks and appreciate your feedback

Noted. Thanks for detail steps. Let's me try and revert back if i facing the issue.

Recent jetty is not available in packages, but it's easy to install by hand:

curl -O https://repo1.maven.org/maven2/org/eclipse/jetty/jetty-home/12.0.17/jetty-home-12.0.17.tar.gz # download latest Jetty12
tar zxf jetty-home-12.0.17.tar.gz -C /opt # unpack it to /opt/
ln -s  /opt/jetty-home-12.0.17 /opt/jetty-home-12 # make a symlink without a minor version, so every upgrade you don't have to modify systemd unit
mkdir /opt/netxms-web/ # actual work area for the web
cd /opt/netxms-web/
java -jar /opt/jetty-home-12.0.17/start.jar --add-modules=server,http,ee8-deploy,gzip,http2,https,logging-logback,plus,ssl,work # create default configuration for jetty
vim start.d/ssl.ini # change keyStorePath and keyStorePassword to match your keystrore
curl -o webapps/ROOT.war https://netxms.com/download/releases/5.1/nxmc-5.1.4.war # download war file to webapps/ROOT.war, so app will be available at /
java -jar /opt/jetty-home-12.0.17/start.jar # test that it runs

useradd -r -s /sbin/nologin jetty # create user so we don't run it as root
systemctl edit --full --force netxms-web.service # create service, paste sample from bellow
systemctl enable --now netxms-web.service # enable autostart and start immediately

Sorry to disturb u. When u said " deploy it into java application server (e.g. Jetty9-12 or Tomcat9)"   is it means we need to deploy another new server? Sorry i'm not get what u suggest. Can u share the url so i can try read to understand it? 

Thanks

Yes, you can setup web interface and use browser for accessing that.

Download war file from https://netxms.com/download/releases/5.1/nxmc-5.1.4.war, and deploy it into java application server (e.g. Jetty9-12 or Tomcat9)
