Apache Tomcat

Posted onby admin

Apache Tomcat (formerly known as Jakarta Tomcat) is an open-source web server developed by Apache to provide a Java HTTP server that allows you to easily run Java files.


Most of you might be using a web server like Apache, Nginx, IIS in front of Tomcat so you may implement the headers directly in web server. However, if you don’t have any web server in front or need to implement directly in Tomcat then good news if you are using Tomcat 8. Nowadays, Apache Tomcat is widely used by many companies as it implements many of the Java EE specifications, such as: Java Servlet. JavaServer Pages, Java Expression Language, Java WebSockets. The current version of Apache Tomcat is 9.x and it is still under the focus of development. Tomcat 5 Downloads: Welcome to the Tomcat 5.x download page. This page provides download links for obtaining the latest versions of all Tomcat release branches, as. Apache Tomcat is open source web server software for Java programming that is developed and maintains by the Apache software foundation. The initial idea of Apache tomcat software was to host and deploy the Java servlet that is the server-side Java code that manages HTTP results from client application build using Java.

This means that Tomcat is not a normal server similar to Apache or Nginx since its main purpose is to provide a good web environment for running Java applications that other web servers do not.

Recently On February 2, 2021, Apache Tomcat reached version 10 (version 10.0.2), which is the first stable version of the 10.x.0 series.

There are a number of notable changes in version 10 of Apache Tomcat.

In this article, we will install Apache Tomcat 9 on RHEL / CentOS 7.0 / 6.x.


Steps To Install Apache Tomcat 10 On CentOS

  1. Java 8 installation and settings
  2. Install Apache Tomcat 10
  3. Apache Tomcat 10 settings
  4. Change Apache Tomcat port

Step 1: Java 8 installation and settings

Before you start installing Tomcat, be sure to install JAVA on your Linux to run Tomcat. Otherwise, install the latest version of Java 9 using yum command.

As soon as java is installed, you can check the version with the following command on your system.

java -version

Output sample:

Step 2: Install Apache Tomcat 9

After installing java on your system, it’s time to download the latest version of Apache Tomcat (version 9.0.14), which is the latest stable version now. If you want to know the newer versions, it is recommended that you check the Apache download page.

Now download the latest version of Apache Tomcat 9 using the wget command and install it as below.

Tip: Replace the version in the above commands with the version you downloaded yourself.

Before starting the Tomcat service, define the CATALINA_HOME environmental variable in your system using the following command.

We can now set up a Tomcat web server using the script provided by the Tomcat package.

Output sample:

Now open Tomcat from your browser. Use your IP or Domain with the 8080 port (because the tomcat always runs on the 8080 port). For example, mydomain.com:8080, which uses your IP or domain address instead of mydomain.com.


The default directory for Tomcat files is located in usr/local/tomcat9/, ‌ You can see the configuration files in the conf folder. You see the above home page he home page when you open your website on port 8080 in the path /usr /local /tomcat9/webapps/ROOT/.

Step 3: Apache Tomcat 9 settings

By default, you will only be able to access the Tomcat default page. To access admin and other sections such as Server Status, App Manager, and Host Manager, you need to configure the user account for admin and administrators.

To do this, you need to edit the “tomcat-users.xml” file located in the /usr/local/tomcat9/conf/ directory.

Set up User Accounts in Tomcat

For example, to assign the role of manager-gui to a user named linuxzone and the password t$cm1n1, add the following line to the config file inside the desired section.

vi /usr/local/tomcat9/conf/tomcat-users.xml

Similarly, you can also add the admin-gui role to an admin user named admin with the admin password as below.

Restart Tomcat after admin settings and management roles, and then try to access the admin section.

Then click the Server Status tab, you will be prompted to enter your username and password. Enter the username and password that you added to the configuration file above.

As soon as you enter the username and password, you will see a page similar to the one below.

Step 4: Change Apache Tomcat port

If you want to run Tomcat on a different port like Port 80, you must edit the server.xml file in the /usr/local/tomcat9/conf/ path. Before changing the port, make sure the Tomcat service is stopped using the following command.

Now open the server.xml file using the vi/vim editor.

Now search for Connector port and change its value from 8080 to 80 or whatever you want.

Run the following command to save the file and restart the Apache Tomcat service.

Your server is now running on port 80.

You must execute all of the above commands under the root user. If you are not a root user, they will not work because we are working in the /usr/local/ directory where the owner of this directory is the only root. If you want, you can run the server with a normal user, but you will have to use your HOME folder as a workspace to download, extract, and run the Apache Tomcat server.

To get some information about the running Tomcat server, run the following command.
