Prerequisites<\/h2>
Before you begin with the guide, have a non-root user with sudo privileges set up on your server. Remember to access your server with SSH<\/a>. Check out our PuTTY tutorial<\/a> if you’re having issues. Alternatively, you can access our browser-based SSH terminal straight from hPanel:<\/p> This tutorial will teach you how to install Tomcat 9 on Ubuntu, and how to configure it for use. <\/p> Before we install Tomcat on Ubuntu, we need to install Java to execute the Java web application code. OpenJDK is the default Java development in Ubuntu. Installing Java is simple and quick. Just follow the below commands:<\/p> Install the OpenJDK<\/a> package by running:<\/p> Now that JDK is installed in your system, you can create the user tomcat by following the next step.<\/p> For security, you should not use Tomcat without a unique user. This will make the install of Tomcat on Ubuntu easier. Create a new tomcat group that will run the service:<\/p> Now, the next procedure is to create a new tomcat user. Create user members of the Tomcat group with a home directory opt\/tomcat for running the Tomcat service:<\/p> The best way to install Tomcat 9 on Ubuntu is to download the latest binary release from the Tomcat 9 downloads page<\/a> and configure it manually. If the version is not 9.0.60 or it’s the latest version, then follow the latest stable version. Just copy the link of the core tar.gz<\/a> file under the Binary Distributions section.<\/p> Now, change to the \/tmp<\/strong> directory on your server to download the items which you won’t need after extracting the Tomcat contents:<\/p> To download from the copied link (from Tomcat website), use the following curl command<\/a>:<\/p> Now that you finished the install of Tomcat on Ubuntu, you need to set up the Tomcat user to have full access to the Tomcat installation. This user needs to have access to the directory. Follow the steps below:<\/p> Now, give the Tomcat group ownership over the entire installation directory with the chgrp command<\/a>:<\/p> Next, you need to give the Tomcat user access to the conf directory to view its contents and execute access to the directory itself:<\/p> Make the Tomcat user the owner of the web apps, work, temp, and logs directories:<\/p> \n\n\n Check out our other article to learn more about changing permissions and owners in Linux<\/a> using command-line interface.<\/p>\n <\/div>\n\n\n\n<\/p> We will need to create a new unit file to run Tomcat as a service. Open your text editor and create a file name tomcat.service in the \/etc\/systemd\/system\/<\/strong>:<\/p> Next, paste the following configuration:<\/p> Save and close the file after finishing the given commands above.<\/p> Next, Notify the system that you have created a new file by issuing the following command in the command line:<\/p> The following commands will allow you to execute the Tomcat service:<\/p> It is essential to adjust the firewall so the requests get to the service. Tomcat uses port 8080 to accept conventional requests. Allow traffic to that port by using UFW<\/a>:<\/p> You can also set up a firewall via hPanel. Select your VPS and navigate to the Firewall<\/strong> section:<\/p> Then create a new firewall configuration and give it a name. Once created, click the Edit<\/strong> button:<\/p> Lastly, add any preferred configuration and click Add rule<\/strong>:<\/p> Follow the command below to access the splash page by going to your domain or IP address followed by :8080 in a web browser – http:\/\/IP:8080<\/p> Follow the command below to add a login to your Tomcat user and edit the tomcat-users.xml<\/strong> file:<\/p> Now, define the user who can access the files and add username and passwords:<\/p> For the Manager app, type:<\/p> For the Host Manager app, type:<\/p> To restart the Tomcat service and view the effects:<\/p> Now that you already have a user, you can access the web management interface in a browser. Once again, you can access the interface by providing your server’s domain name or IP address followed by port 8080 in your browser – http:\/\/server_domain_or_IP:8080<\/p> Let’s take a look at the Manager App, accessible via the link – http:\/\/server_domain_or_IP:8080\/manager\/html.<\/p> Make sure that you entered the account credentials to the t<\/strong>omcat-users.xml<\/strong> file.<\/p> We use the Web Application Manager<\/strong> to manage our Java applications. You can Begin, Stop, Reload, Deploy, and Undeploy all apps here. Lastly, it provides data about your server at the bottom of the page.<\/p> Now let’s look at the Host Manager<\/strong>, accessible via http:\/\/server_domain_or_IP:8080\/host-manager\/html\/<\/p> From the Virtual Host Manager<\/strong> page, you can also add new virtual hosts that follow your application form’s guidelines.<\/p> Ubuntu supports Tomcat 6 and the latest version Tomcat 9 which includes new features to allow users to work freely on the application.<\/p> With this tutorial, your Tomcat installation is functional but entirely unencrypted, so other parties on a web browser can view or change the information or data, passwords, and other sensitive data. The only way to resolve this issue is to encrypt your connections with SSL.<\/p> \n\n\n How to List Packages in Ubuntu<\/a> In this section, we’ll cover some of the most common questions for configuring Tomcat on Ubuntu.<\/p> To install Tomcat on Ubuntu, use sudo apt install tomcat9<\/strong> for Tomcat version 9. Adjust the version number based on your requirements.<\/p> <\/div> Yes, you can install multiple Tomcat versions on Ubuntu. Ensure they are configured to run on different ports to avoid conflicts.<\/p> <\/div> The default installation directory for Tomcat on Ubuntu is \/var\/lib\/tomcat9<\/strong> for Tomcat 9. This path varies with the version.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":" Tomcat, often called Apache Tomcat, is one of the most popular applications designed to execute a Java servlet and render web servers with Java page coding. It is an open-source application released by Apache Software Foundation. Many developers favor it!
