This tutorial exists for these OS versions. Ubuntu 18.04 (Bionic Beaver).On this page.Apache Tomcat is an open source Java Servlet implementation developed by the Apache Software Foundation. In addition to the implementation of Java Servlets, Tomcat supports other Java server technologies too, including JavaServer Pages (JSP), Java Expression Language, and Java WebSocket.

Tomcat provides an HTTP Web Server for Java applications that supports HTTP/2, OpenSSL for JSSE, and TLS virtual hosting.In this tutorial, we will show you how to install and configure the Apache Tomcat 9.0.8 on Ubuntu 18.04 LTS (Bionic Beaver). We will also learn how to install Java on Ubuntu 18.04 LTS, configure a user for apache tomcat, and run the apache tomcat as a systemd service. Prerequisites.

Ubuntu 18.04 - 64bit. 2 GB or more memory (Recommended). Root PrivilegesWhat we will do?.

Install Java on Ubuntu 18.04. Configure Java Environment. Install Apache Tomcat 9. Configure Apache Tomcat as a Service.

Configure Apache Tomcat Users. TestingStep 1 - Install Java on Ubuntu 18.04In this step, we will install Java JRE and JDK from the PPA repository. To do that, we have to install a new package 'software-properties-common' first for managing the repository.

Sudo apt install oracle-java8-installer -yWhen the installation is complete, check the java version installed on the system. Java -versionAnd you will get the result as below. Java version '1.8.0171'Java(TM) SE Runtime Environment (build 1.8.0171-b11)Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)Java has been installed on Ubuntu 18.04. Step 2 - Configure Java EnvironmentIn the first step, we've installed Java.

Now we need to configure the JAVAHOME environment variable on the Ubuntu server so that Java applications can find the Java installation directory. Tomcat needs a JAVAHOME environment to be set up properly.Before we configure the JAVAHOME environment, we need to know where the Java directory is. Check the location of the Java directory with the command below: sudo update-alternatives -config javaThe java directory is ' /usr/lib/jvm/java-8-oracle/jre'Now edit the '/etc/environment' file using.

Vim /etc/environmentPaste the following configuration there. JAVAHOME='/usr/lib/jvm/java-8-oracle/jre'Save and exit.Edit the '/.bashrc' file. Vim /.bashrcPaste the below configuration.

Export JAVAHOME=/usr/lib/jvm/java-8-oracle/jreexport PATH=$JAVAHOME/bin:$PATHSave and exit. AdvertisementsNow reload the '/.bashrc' script and test the 'JAVAHOME' directory. Source /.bashrcecho $JAVAHOMEThe java environment setup has been completed. Step 3 - Install Apache TomcatIn this step, we will install the Apache Tomcat under the 'tomcat' user and group. We will download the apache tomcat binary files, configure the Catalina tomcat servlet container environment, and do a first test of the Tomcat server.Add new user and group named 'tomcat' using the commands below. Advertisements groupadd tomcatuseradd -s /bin/false -g tomcat -d /opt/tomcat tomcatNow go to the '/opt/' directory and download the latest apache tomcat stable version (9.0.8) using the wget command. Cd /opt/wget the apache tomcat package file and rename the directory to 'tomcat'.

Tar -xzvf apache-tomcat-9.0.8.tar.gzmv apache-tomcat-9.0.8/ tomcat/Change the owner of tomcat directory and files to the 'tomcat' user and group, then make all apache tomcat binary files executable. Chown -R tomcat:tomcat /opt/tomcatchmod +x /opt/tomcat/bin/.Next, we will configure the Catalina tomcat servlet container environment by editing the '/.bashrc' file using vim.

Vim /.bashrcPaste the following configuration there. Export CATALINAHOME=/opt/tomcatSave and exit.Reload the '/.bashrc' file and test the Catalina environment. Source /.bashrcecho $CATALINAHOMEYou will get the result as shown below.Now test to run the Apache Tomcat itself. AdvertisementsRun the command below to start Apache tomcat. $CATALINAHOME/bin/startup.shAnd you'll see the result - apache tomcat has been started. It will run on the default port '8080' - you can check the port using netstat command. Netstat -plntuThe Apache Tomcat is running the server under port 8080.Another way for testing the apache tomcat is by visiting the server IP address with port 8080.And you will see the apache tomcat homepage as below.Apache Tomcat has been installed on Ubuntu 18.04.Now run the command below to stop the apache tomcat.

$CATALINAHOME/bin/shutdown.shchown -hR tomcat:tomcat /opt/tomcat/Step 4 - Configure Apache Tomcat as a ServiceIn this tutorial, we want to run Apache Tomcat as tomcat user with a systemd service file so it can be started and stopped easily. Now we need to create the 'apache-tomcat.service' file.Go to the systemd system directory and create a new file 'apache-tomcat.service'.

Cd /etc/systemd/system/vim apache-tomcat.servicePaste the following configuration there: UnitDescription=Apache Tomcat 9 Servlet ContainerAfter=syslog.target network.targetServiceUser=tomcatGroup=tomcatType=forkingEnvironment=CATALINAPID=/opt/tomcat/tomcat.pidEnvironment=CATALINAHOME=/opt/tomcatEnvironment=CATALINABASE=/opt/tomcatExecStart=/opt/tomcat/bin/startup.shExecStop=/opt/tomcat/bin/shutdown.shRestart=on-failureInstallWantedBy=multi-user.targetSave and exit.Now reload the systemd service. Systemctl daemon-reloadAnd start the 'apache-tomcat' service using the systemctl commands below. Systemctl start apache-tomcatsystemctl enable apache-tomcatThe Apache Tomcat is now running as a service on Ubuntu 18.04, check it using following commands. Netstat -plntusystemctl status apache-tomcatThe Apache Tomcat is now running and it's using the port 8080 as a default port.

Step 5 - Configure Apache Tomcat UserIn this step, we will configure the users for Apache Tomcat. We will add a new user to access the manager UI, and then allow the manager and host-manager access. AdvertisementsGo to the '/opt/tomcat/conf' directory and edit the 'tomcat-users.xml' file using vim. Cd /opt/tomcat/confvim tomcat-users.xmlPaste the following configuration before the closing configuration ' '.

Sony vaio backlit keyboard drivers for mac windows 7.

Save and exit.Now allow external access to the 'manager' dashboard by editing it's configuration 'context.xml' file. Cd /opt/tomcat/webapps/manager/META-INF/vim context.xmlComment the 'allow' line 19-20.

Cd /opt/tomcat/webapps/host-manager/META-INF/vim context.xmlComment the 'allow' line 19-20.
