We’ll make this user a member of the tomcat group, with a home directory of /opt/tomcat (where we will install Tomcat), and with a shell of /bin/false (so nobody can log into the account): We will create a new user and group that will run the Tomcat service. Step 2 - Create Tomcat Userįor security purposes, Tomcat should be run as an unprivileged user (i.e. Now that Java is installed, we can create a tomcat user, which will be used to run the Tomcat service. Then install the Java Development Kit package with apt: We can satisfy that requirement by installing OpenJDK with apt. Tomcat requires Java to be installed on the server so that any Java web application code can be executed. You can learn how to do this by completing our Ubuntu 18.04 initial server setup guide.

Prerequisitesīefore you begin with this guide, you should have a non-root user with sudo privileges set up on your server.

This tutorial covers the basic installation and some configuration of the latest release of Tomcat 9 on your Ubuntu 18.04 server. Tomcat is an open source implementation of the Java Servlet and JavaServer Pages technologies, released by the Apache Software Foundation. ~]# cd localhost]# vi manager.Apache Tomcat is a web server and servlet container that is used to serve Java applications. Scenario :if you have installed Tomcat on remote server and want to access ‘Manger App’ and ‘Server Status’ on your local system’s web browser for that we need to create a file “ manager.xml” under the folder “ /opt/tomcat/conf/Catalina/localhost/” with the following content. Similarly We can view the Server Status by clicking on the option “ Server Status” In my case ip address of my server is “192.168.43.9”Ĭlick on “ Manager App”, It will prompt us for the User name and password, specify the user’s credentials whatever we set in the file ‘ tomcat-users.xml‘ Open the web broswer type the following URL : Rule added You can skip this step if firewall is disabled on your server Step:6 Access Apache Tomcat 9 page from the Web Browser Use the below command to open 8080 port in Ubuntu 16.04 / 16.10 firewall. ~]# firewall-cmd -permanent -zone=public ~]# firewall-cmd ~]# shutdown.shĪs we know by default tomcat runs on 8080 port so in case firewall is running on your Linux box then set the following rule to open 8080 port on CentOS 7.x and RHEL 7.x. To shutdown the tomcat service use below command bin]#. Run the beneath commands one after the another to start tomcat service. ' roles='admin-gui' /> Step:5 Start Tomcat Service So to grant access to the users add the following lines in the file “/ opt/tomcat/conf/tomcat-users.xml” just above tag ~]# tar -zxpvf apache-tomcat-9.0.0. -C ~]# cd opt]# mv apache-tomcat-9.0.0. tomcatīefore starting the Tomcat Service let’’s first set the required CATALINA_HOME environment variable using below commands : ~]# echo 'export CATALINA_HOME='/opt/tomcat/'' > ~]# source ~]# Step:4 Specify the Users for Manager GUI Page and Admin Page Access.īy default no user or account is allowed to access Manager GUI Page and Admin Page. Run the beneath tar command to extract Apache tomcat 9 under the /opt folder. We can download Apache tomcat 9 tar.gz either from its official Web site or using wget command from the terminal.ĭownloading Tomcat from the terminal ~]# wget Step:3 Extract the downloaded file and set CATALINA_HOME variable OpenJDK 64-Bit Server VM (build 25.91-b14, mixed Step:2 Download the Apache Tomcat 9 tar.gz file

Java 8 is also available in Ubuntu 16.04/16.10 apt repositories, run the following apt command to install Java 8 sudo apt sudo apt install openjdk-8* OpenJDK Runtime Environment (build 1.8.0_101-b13) Run the beneath command to check Java version : ~]# java -version
