The default Tomcat server runs on port 8080. For iptables: sudo iptables -A INPUT -p tcp -dport 8080 -j ACCEPT.For FirewallD in CentOS: sudo firewall-cmd -zone=public -add-port=8080/tcp -permanent sudo firewall-cmd -reload.For UFW (Uncomplicated Firewall) in Ubuntu: sudo ufw allow 8080.This depends on what firewall you are using: You also need to check if the firewall is not blocking the incoming connections to Tomcat’s port (default is 8080). If everything went well, enable Tomcat to start on boot: sudo systemctl enable tomcat Step 10: Open the Firewall Next, start the Tomcat service with: sudo systemctl start tomcatĬheck the status to ensure it’s running properly: sudo systemctl status tomcat Step 9: Start and Enable TomcatĪfter creating the service file, reload the systemd daemon to read the new file: sudo systemctl daemon-reload Open a new service file in a text editor: sudo nano /etc/systemd/system/rvice We’ll now create a systemd service file to manage the Tomcat service. Similarly edit context.xml for host manager application in text editor: sudo nano /opt/tomcat/webapps/host-manager/META-INF/context.xmlĬomment out the same section to allow connections from anywhere. Edit the context.xml file for manager and host manager application: sudo nano /opt/tomcat/webapps/manager/META-INF/context.xmlĬomment out the section added for IP address restriction to allow connections from anywhere. You can either allow a specific remote system or allow all. To allow access to these pages from the remote system, you need to modify the following configuration files. The default Tomcat manager and host-manager applications are accessible for localhost only. Step 7: Allow Remote Hosts to Access Tomcat Make sure to change the password for admin and manager access. sudo nano /opt/tomcat/conf/tomcat-users.xmlĪdd the following values. We recommend changing the password in the below configuration with high secured password. To do this, edit conf/tomcat-users.xml file in your editor and paste the following code inside tags. Now, configure your tomcat with user accounts to secure access of admin/manager pages. sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh' Step 6: Create Tomcat Application Accounts Next, make all scripts within the bin directory executable. We need to give the tomcat user ownership over the extraction directory and make the scripts in the bin directory executable.įirst, we’ll change the directory ownership to tomcat. sudo tar xzf apache-tomcat-*.tar.gz -C /opt/tomcat Step 5: Set Permissions Once the download is complete, we’ll extract it to the /opt/tomcat directory. As of my writing, the latest stable version is 10.1.10.ĭownload the tar.gz file to the /tmp directory: wget Next, navigate to the Apache Tomcat official download page ( ), and grab the latest version of the binary distribution in tar.gz format. sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcat Step 4: Download and Extract Tomcat 10 Therefore, we’ll create a new system user with home directory /opt/tomcat. Step 3: Create Tomcat Userįor security reasons, Tomcat should not be run under the root user. You should see an output confirming the installed version of OpenJDK. You can verify the installation with the following command: java -version Since Tomcat 10 requires JDK 11 or newer, we will install OpenJDK 11. Open your terminal, and enter the following command: sudo apt update & sudo apt upgrade -y Step 2: Install Java Development Kit (JDK)Īs Tomcat is a Java server, we need to have JDK installed on the system. It’s always a good idea to update the package lists for upgrades and new installations. Java Development Kit (JDK) installed (Tomcat 10 requires JDK 11 or later).A terminal window/command line (Ctrl-Alt-T).Access to a user account with sudo or root privileges.We’ll also discuss some important concepts related to the installation, such as setting up the environment, downloading and installing the necessary packages, and configuring the Tomcat instance. In this tutorial, we’ll walk you through the steps of installing Tomcat 10 on Ubuntu 22.04. It’s easy to install and use, and provides a powerful platform for web applications. It is developed by the Apache foundation and still provides upgrades and features. Apache Tomcat is an open-source web application server designed for hosting Java-based applications.
