Install Jetty on a CentOS 7 VPS

jetty-logoIn the following article we are going to explain how you can install Jetty on a CentOS 7 VPS.

Jetty is a Java HTTP (Web) server and Java Servlet container and provides support for SPDY, WebSocket, OSGi, JMX, JNDI, JAAS and many other integrations. It is often used for machine to machine communications, within larger software frameworks. Jetty is developed as a free and open source project as part of the Eclipse Foundation.

Jetty is used in a wide variety of projects and products, both in development and production. It can be easily embedded in devices, tools, frameworks, application servers, and clusters.

Jetty has the following features:

  • Full-featured and standards-based
  • Open source and commercially usable
  • Flexible and extensible
  • Small footprint
  • Embeddable
  • Asynchronous
  • Enterprise scalable
  • Dual licensed under Apache and Eclipse


We will be using our CentOS 7 minimal Linux VPS template for this tutorial.


As always, make sure your server is fully up-to-date with the command below:

# yum update

Also, install unzip and a text editor of your choice. We will use nano as our text editor:

# yum install nano unzip


Jetty requires JAVA in order to run. We are going to install the latest version of Oracle’s JAVA JDK 8. At the time of writing this article, the latest version of JAVA is 8u60 and can be downloaded and installed using the command below:

# wget --no-cookies --no-check-certificate --header "Cookie: oraclelicense=accept-securebackup-cookie" "" -O /opt/jdk-8-linux-x64.rpm

Install JAVA:

# yum install /opt/jdk-8-linux-x64.rpm

Configure the JAVA package using the alternatives command:

# JDK_DIRS=($(ls -d /usr/java/jdk*))

# JDK_VER=${JDK_DIRS[@]:(-1)}

# alternatives --install /usr/bin/java java /usr/java/"${JDK_VER##*/}"/jre/bin/java 20000

# alternatives --install /usr/bin/jar jar /usr/java/"${JDK_VER##*/}"/bin/jar 20000

# alternatives --install /usr/bin/javac javac /usr/java/"${JDK_VER##*/}"/bin/javac 20000

# alternatives --install /usr/bin/javaws javaws /usr/java/"${JDK_VER##*/}"/jre/bin/javaws 20000

# alternatives --set java /usr/java/"${JDK_VER##*/}"/jre/bin/java

# alternatives --set javaws /usr/java/"${JDK_VER##*/}"/jre/bin/javaws

# alternatives --set javac /usr/java/"${JDK_VER##*/}"/bin/javac

# alternatives --set jar /usr/java/"${JDK_VER##*/}"/bin/jar

You may want to check if JAVA has been properly setup on your server using:

# java -version


We will download and unpack the Jetty installation archive into the /opt directory. Currently, while this article has been written, the latest Jetty version is 9.3.3, so we will download that one. Enter the following commands:

# cd /opt

# wget

# unzip

Rename the Jetty installation directory into one with an easier name:

# mv jetty-distribution-9.3.3.v20150827 jetty

Create a user called Jetty and configure the correct file ownership:

# useradd -m jetty

# chown -R jetty:jetty /opt/jetty/

Symlink the script to the /etc/init.d/ directory to create a start up script file:

# ln -s /opt/jetty/bin/ /etc/init.d/jetty

Add the script:

# chkconfig --add jetty

Configure Jetty to start on system boot:

# chkconfig --level 345 jetty on

Now, you need to create a configuration file for Jetty. Open a file:

# nano /etc/default/jetty

Now paste the following:


Don’t forget to add your server IP address in the JETTY_HOST line.

Navigate to the Jetty installation directory:

# cd /opt/jetty

Next, delete the webapps directory since there is nothing in it and copy the webapps directory from demo-base. It is a test and demo data from Jetty.

# rm -rf webapps/

# cp -r demo-base/webapps/ /opt/jetty/

Start Jetty:

# service jetty start

With the curl command test if you can retrieve the index page.

# curl localhost:8080

Or open your favorite web browser and navigate to http://your_server_IP:8080 after which you will see the welcome page like the image below:


Congratulations. You have successfully installed Jetty on your CentOS 7 VPS. You can now check the Jetty documentation for more information.
