How to make Jetty webserver listen on port 80?

I would like to use Jetty as a webserver.

I have edited the configuration file at /etc/default/jetty and set:

# change to 0 to allow Jetty start
NO_START=0

# Listen to connections from this network host
# Use 0.0.0.0 as host to accept all connections.
JETTY_HOST=0.0.0.0

Now I can reach the Jetty webserver at http://192.168.1.10:8080 but I would like to have Jetty listening on port 80.

I have tried this setting in the same configuration file:

# The network port used by Jetty
JETTY_PORT=80

and then restart Jetty with sudo service jetty restart but it doesn't work.

How can I change so that the Jetty webserver is listening on port 80?

Solution 1:

You will need to edit the /etc/jetty/jetty.xml file. Look for a paragraph that says:

<Call name="addConnector">
      <Arg>
          <New class="org.mortbay.jetty.nio.SelectChannelConnector">
            <Set name="host"><SystemProperty name="jetty.host" /></Set>
            <Set name="port"><SystemProperty name="jetty.port" default="8090"/></Set>
            <Set name="maxIdleTime">30000</Set>
            <Set name="Acceptors">2</Set>
            <Set name="statsOn">false</Set>
            <Set name="confidentialPort">8443</Set>
        <Set name="lowResourcesConnections">5000</Set>
        <Set name="lowResourcesMaxIdleTime">5000</Set>
          </New>
      </Arg>
    </Call>

Change the jetty.port Property to 80 as follows:

<Set name="port"><SystemProperty name="jetty.port" default="80"/></Set>

Restart jetty. That should do it.

Solution 2:

I am using Jetty 9. In the file start.ini you can find and modify the property jetty.port. Then you have to restart jetty.service.
