Connect to the Server<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>To connect to your server via SSH as the root user, use the following command:<\/p>\r\n<pre>ssh root@<span style=\"color: #ff0000;\">IP_ADDRESS<\/span> -p <span style=\"color: #ff0000;\">PORT_NUMBER<\/span><\/pre>\r\n<p>and replace \u201c<span style=\"color: #ff0000;\">IP_ADDRESS<\/span>\u201d and \u201c<span style=\"color: #ff0000;\">PORT_NUMBER<\/span>\u201d with your actual server IP address and SSH port number.<\/p>\r\n<p>Once logged in, let\u2019s make sure that your Ubuntu 18.04 server is up-to-date by running the following commands:<\/p>\r\n<pre>$ apt-get update\r\n$ apt-get upgrade<\/pre>\r\n<p>This helps maximize compatibility and security between packages and ensures that the install process will go smoothly.<\/p>\r\n<h2><span class=\"ez-toc-section\" id=\"Step-2-Install-Java-on-Ubuntu-1804\"><\/span>Step 2: Install Java on Ubuntu 18.04<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>Jetty 9 depends on the Java Development Kit (JDK).\u00a0We can check if Java is already installed using this command:<\/p>\r\n<pre>which java<\/pre>\r\n<p>If there is no output, it means that Java is not installed on the server yet.<\/p>\r\n<p>You can install\u00a0<strong>Oracle JDK<\/strong>\u00a0or\u00a0<strong>OpenJDK<\/strong> depending on your choice. We&#8217;ll use\u00a0<strong>OpenJDK<\/strong>, as that&#8217;s what\u00a0is readily available in the pre-installed Ubuntu package repositories. They are functionally identical, so choosing either one will not affect how the program runs. We also included the Oracle JDK install further down below if necessary.<\/p>\r\n<p>You can install OpenJDK with the following command:<\/p>\r\n<pre>$ sudo apt install openjdk-8-jdk<\/pre>\r\n<p>To check if everything is set correctly, run this next line:<\/p>\r\n<pre>$ java -version<\/pre>\r\n<p>After which you should see something like the following:<\/p>\r\n<pre>openjdk version \"1.8.0_212\"\r\nOpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.18.04.1-b03)\r\nOpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)\r\n<\/pre>\r\n<p>If however, you have a specific reason to use the Oracle JDK, this command will install Oracle JDK 8 using the PPA repository:<\/p>\r\n<pre>$ sudo add-apt-repository ppa:webupd8team\/java\r\n$ sudo apt-get update\r\n$ sudo apt-get install oracle-java8-installer<\/pre>\r\n<h2><span class=\"ez-toc-section\" id=\"Step-3-Install-Jetty-9\"><\/span>Step 3: Install Jetty 9<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>Jetty 9 is available in the pre-installed Ubuntu package repositories. You can install it with the following command:<\/p>\r\n<pre>$ sudo apt install jetty9<\/pre>\r\n<p>Once the installation is complete, Jetty 9 will be automatically started.<\/p>\r\n<p>To check and verify the installed Jetty version, run the following command:<\/p>\r\n<pre>$ apt show jetty<\/pre>\r\n<p>At which point you should see something like the following. You might have a later version than the one shown here:<\/p>\r\n<pre>Package: jetty9\r\nVersion: 9.4.15-1~18.04.1ubuntu1\r\nPriority: optional\r\nSection: universe\/java\r\nOrigin: Ubuntu<\/pre>\r\n<h2><span class=\"ez-toc-section\" id=\"Step-4-Managing-the-Jetty-9-Service\"><\/span><span class=\"ez-toc-section\">Step 4: Managing the <\/span>Jetty 9 <span id=\"Managing-the-GlassFish-Service\" class=\"ez-toc-section\">Service<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>Enable the Jetty 9 at boot time using the following command:<\/p>\r\n<pre>$ sudo systemctl enable jetty9<\/pre>\r\n<p>Start Jetty 9 service using this command:<\/p>\r\n<pre>$ sudo systemctl start jetty9<\/pre>\r\n<p>We can restart Jetty 9 using:<\/p>\r\n<pre>$ sudo systemctl restart jetty9<\/pre>\r\n<p>In order to stop Jetty 9, we can use this command:<\/p>\r\n<pre>$ sudo systemctl stop jetty9<\/pre>\r\n<p>We can check the service status using:<\/p>\r\n<pre>$ systemctl status jetty9<\/pre>\r\n<p>The output of this command should be similar to this:<\/p>\r\n<pre><span style=\"color: #2be02b;\">\u25cf<\/span> jetty9.service - Jetty 9 Web Application Server\r\n   Loaded: loaded (\/lib\/systemd\/system\/jetty9.service; enabled; vendor preset: enabled)\r\n   Active: <span style=\"color: #2be02b;\">active (running)<\/span> \r\n     Docs: https:\/\/www.eclipse.org\/jetty\/documentation\/current\/\r\n Main PID: 19382 (java)\r\n    Tasks: 24 (limit: 2321)\r\n   CGroup: \/system.slice\/jetty9.service\r\n           \u2514\u250019382 \/usr\/bin\/java -Djetty.home=\/usr\/share\/jetty9 -Djetty.base=\/usr\/share\/jetty9 -Djava.io.tmpdir=\/tmp -jar \/usr\/share\/jetty9\/start.jar jetty.state=\/var\/lib\/jetty9\/jetty.state jetty-started.xml<\/pre>\r\n<h2><span class=\"ez-toc-section\" id=\"Step-5-Accessing-the-Jetty-Installation\"><\/span>Step 5: Accessing the Jetty Installation<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<p>Jetty runs on port 8080.

This means that Apache will accept all requests through port 80 in front of Jetty 9, which is running on port 8080. In order to do this, we&#8217;ll need to enable two Apache modules:\u00a0<strong>proxy<\/strong>\u00a0and\u00a0<strong>proxy_http<\/strong>. We can use the &#8216;a2enmod&#8217; command to enable them:<\/p>\r\n<pre>$ sudo a2enmod proxy\r\n$ sudo a2enmod proxy_http<\/pre>\r\n<p>After we install these modules, we have to restart Apache for the changes to take effect:<\/p>\r\n<pre>$ sudo systemctl restart apache2<\/pre>\r\n<p>Create\/modify the virtual host configuration about your domain and add\/modify the proxy directives (ProxyRequests, ProxyPass and ProxyPassReverse) as shown in our example:<\/p>\r\n<pre>$ sudo nano \/etc\/apache2\/sites-available\/<span style=\"color: #ff0000;\">your_domain.com<\/span>.conf<\/pre>\r\n<p>Copy and paste the content below in the Apache configuration file and save it. Don&#8217;t forget to replace \u201c<span style=\"color: #ff0000;\">your_domain.com<\/span>\u201d with your own domain name. <strong>NOTE:<\/strong>\u00a0This tutorial assumes that you already have a registered domain name that&#8217;s already configured to point towards your server&#8217;s IP address. Enter the following data:<\/p>\r\n<pre>&lt;VirtualHost *:80&gt;\r\n  ServerName <span style=\"color: #ff0000;\">your_domain.com<\/span>\r\n  ServerAlias www.<span style=\"color: #ff0000;\">your_domain.com<\/span>\r\n  ProxyRequests off \r\n  ProxyPass \/ http:\/\/127.0.0.1:8080\/ \r\n  ProxyPassReverse \/ http:\/\/127.0.0.1:8080\/ \r\n&lt;\/VirtualHost&gt;<\/pre>\r\n<p>Enable the \u2018<span style=\"color: #ff0000;\">your-domain.com<\/span>.conf\u2019 Apache configuration file if it was not previously enabled, and restart Apache for the changes to take effect:<\/p>\r\n<pre>$ sudo a2ensite <span style=\"color: #ff0000;\">your_domain.com<\/span>.conf\r\n$ sudo systemctl restart apache2<\/pre>\r\n<p>Now we can access the Jetty 9 webapp without needing to specify port 8080 in a web browser, meaning that we can now access it using: <code>http:\/\/your-domain.com<\/code>.<\/p>\r\n<p>That&#8217;s all there is to it.
