    Step 1 – Verify JAVA

    JAVA is the first requirement of Tomcat installation. Use the following command to check if you have java installed already on your system.

    # java -version

openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-8u282-b08-0ubuntu1~16.04-b08)
OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode)

    Tomcat 8 is designed to run on Java SE 7 and later. So make sure you have installed the correct version on your system. If you don’t have Java installed on your system or installed lower version, use one of the following links to install Java first.

    Step 2 – Downloading Tomcat Archive

    Download Apache Tomcat 8 archive file using following commands or you can visit Tomcat 8 official download page for download most recent available version. After downloading extract archive file in /opt directory. You may change this location as per your setup.

    wget http://www-us.apache.org/dist/tomcat/tomcat-8/v8.5.51/bin/apache-tomcat-8.5.64.tar.gz
tar xzf apache-tomcat-8.5.64.tar.gz
mv apache-tomcat-8.5.64 /usr/local/tomcat8

    Step 3 – Configure Environment Variables

    Before starting Tomcat, configure CATALINA_HOME environment variable in your system using following commands.

    echo "export CATALINA_HOME="/usr/local/tomcat8"" >> ~/.bashrc
source ~/.bashrc

    Step 4 – Start Tomcat Server

    Tomcat is very easy to use, There is no need to compile its source. You simply extract the archive and start the tomcat server. Tomcat by default start on port 8080, So make sure no other application using the same port.

    cd /usr/local/tomcat8
./bin/startup.sh

    [Sample Output] 

    Using CATALINA_BASE:   /usr/local/tomcat8
Using CATALINA_HOME:   /usr/local/tomcat8
Using CATALINA_TMPDIR: /usr/local/tomcat8/temp
Using JRE_HOME:        /opt/jdk1.8.0_121
Using CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar
Tomcat started.
    Step 5 – Access Tomcat in Browser

    Tomcat server works on port 8080 default. Access tomcat on a web browser by connecting your server on port 8080.

     http://localhost:8080

    install tomcat 8

    Step 6 – Setup User Accounts

    Finally we need to create user accounts to secure and access admin/manager pages. Edit conf/tomcat-users.xml file in your editor and paste inside <tomcat-users> </tomcat-users> tags.

    <!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />

    Share.

      Create tomcat8 file in /etc/init.d/ like this:

      # sudo vim /etc/init.d/tomcat8

      and paste following code:

      #!/bin/bash
      export CATALINA_HOME=/your/path/here
      PATH=/sbin:/bin:/usr/sbin:/usr/bin
      start() {
      sh $CATALINA_HOME/bin/startup.sh
      }
      stop() {
      sh $CATALINA_HOME/bin/shutdown.sh
      }
      case $1 in
      start|stop) $1;;
      restart) stop; start;;
      *) echo “Run as $0 “; exit 1;;
      esac

      And later modify /etc/init.d/tomcat8 file permissions:

      # sudo chmod 755 /etc/init.d/tomcat8

      That is all.
