Install Jetty 9.3 on ubuntu 15.04 server
Prerequisites
You need to install Java before installing jetty server using the following command
sudo apt-get install openjdk-8-jdk
This will install it to /usr/lib/jvm/java-8-openjdk-i386. A symlink java-1.8.0-openjdk-i386 is created in the directory /usr/lib/jvm/. A symlink is also created at /usr/bin/java
Now you need to download Jetty9 from here after downloading you need to extract using the following command
$tar -xvf jetty-distribution-9.3.0.v20150612.tar.gz
This unpacks the jetty-distribution-9.3.0.v20150612 and you need to Move the archive to /opt/jetty using the following command
$mv jetty-distribution-9.3.0.v20150612 /opt/jetty
You need to Create jetty user and make it the owner of /opt/jetty directory
sudo useradd jetty -U -s /bin/false
sudo chown -R jetty:jetty /opt/jetty
Jetty Startup Script
Copy the Jetty script to run as a service using the following command
$ cp /opt/jetty/bin/jetty.sh /etc/init.d/jetty
Now you need to create jetty settings file with the following content
sudo vi /etc/default/jetty
Add the following lines
JAVA_HOME=/usr/bin/java
JETTY_HOME=/opt/jetty
NO_START=0
JETTY_ARGS=jetty.port=8085
JETTY_HOST=0.0.0.0
JETTY_USER=jetty
Save and exit the file
You need to start jetty service using the following command
sudo service jetty start
You should see output similar to the following
Starting Jetty: OK Mon Nov 24 11:55:48 GMT 2014
If you see the following error
** ERROR: JETTY_HOME not set, you need to set it or install in a standard location
You need to make sure you have correct jetty home path in /etc/default/jetty file i.e JETTY_HOME=/opt/jetty
You can test the jetty using the following URL
It should now be running on port 8085! Visit in your browser http://serverip:8085 and you should see a Jetty screen.
Jetty Service checking
Verify and check your configuration with the following command
sudo service jetty check
Jetty automatically start on reboot using the following command
sudo update-rc.d jetty defaults
Reboot the server and test if Jetty starts automatically.
To check which port Jetty is running or whether there are any conflicts with other programs for that port, run netstat -tln
