![]() If deploying Tomcat onto a production environment, consider installing tomcat-native. Install one of tomcat8, tomcat9, or tomcat10. Check the version you need depending on your web applications requirements. The last versions are officially supported in Arch Linux: tomcat8, tomcat9 and tomcat10. Instead, each branch is the implementation of a couple of the "Servlet" and "JSP" Java standards. None of these version deprecates the preceding. You have a running Tomcat server on the Ubuntu 20.04 system.Note: Tomcat currently exists under four stable branches: 7, 8, 9 and 10. You can access tomcat interfaces by entering your server’s IP address or a domain name pointed to that server, followed by port 8080 in your browser: You will see the page like below: As you have configured Tomcat on your system, you can access the web interface from your system. ![]() The default Tomcat server runs on port 8080. Make sure the status is showing “ active (running)“. ![]() You can verify the service status by executing the command as below. sudo systemctl enable rviceĪs of now, the tomcat application is running on your system. This is more important for the production deployments. Next, enable the tomcat service to auto start for subsequent system boots. Now, start the Tomcat application for the first time. ![]() Reload the systemd daemon service to load newly create files. Let’s create a rvice file with the following content: sudo nano /etc/systemd/system/rvice Įnvironment="JAVA_HOME=/usr/lib/jvm/java-1.11.0-openjdk-amd64"Įnvironment="JAVA_OPTS=file:///dev/urandom"Įnvironment="CATALINA_PID=/opt/tomcat/temp/tomcat.pid"Įnvironment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC" But, to make it simpler, create a startup script to manage Tomcat as systemd service. Tomcat provides bash scripts to start, stop service. Step 6 – Create a Tomcat Systemd Unit File Similarly edit context.xml for host-manager application in the 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 the 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 specific remote system or allow all. To allow access 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. 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 to admin/manager pages. You have now the latest Tomcat application on your system. sudo tar xzvf apache-tomcat-10.0.5.tar.gz -C /opt/tomcat -strip-components=1 Once the download completed, extract the downloaded archive and copy all content to the tomcat home directory. Use the below command to download Tomcat 10. So it will be good to check to download the latest Tomcat version from the official download server. The Apache Tomcat development team releases the latest version of Tomcat from time to time. The above command will create a user and group with the name “ tomcat” in your system. To create a new account, type: sudo useradd -m -d /opt/tomcat -U -s /bin/false tomcat Create a new user, which is recommended for security purposes mainly for production deployments. We recommended to run Tomcat server with a dedicated user account. sudo apt updateĬheck the current active Java version: java -version Use the following command to install OpenJDK to fulfill the requirements. Tomcat 10 required to have JRE 8 or higher version installed on your system. You must have JRE (Java runtime environment) installed on your system.
