How to install Apache Tomcat in Ubuntu
This post will describe how to install and configure Apache Tomcat. Apache Tomcat is a Servlet Container for Java-based Web Application. It is an open source software developed by Apache Software Foundation.
It has three major Components
Tomcat v9.08, Ubuntu 18.04 and Java JDK
Step 1 Install Java
Step 2 Create Tomcat User
Step 3 Install Tomcat
Step 4 Configure Tomcat
Step 5 Manage Credentails
Step 6 Start Tomcat
-----------------------------------
STEP 1 : INSTALLING JAVA
If Java JDK is not available install it.
First, update the package index
$ sudo apt-get update
Then install Java JDK
$ sudo apt-get install default-jdk
STEP 2 : CREATE TOMCAT USER
Create new tomcat group
$ sudo groupadd tomcat
Create tomcat user with a home directory where we can install tomcat(/opt/tomcat)
$ sudo useradd -s /bin/false -g groupname -d directory location
$ sudo useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
STEP 3 : INSTALL TOMCAT
use
$ sudo mkdir /opt/tomcat
$ wget http://www-eu.apache.org/dist/tomcat/tomcat-9/v9.0.10/bin/apache-tomcat-9.0.10.tar.gz
$ sudo tar xzvf apache-tomcat-9*tar.gz -C /opt/tomcat --strip-components=1
STEP 4 : CONFIGURE TOMCAT
$ cd /opt/tomcat
$ sudo chgrp -R tomcat /opt/tomcat
$ sudo chmod -R g+r conf
$ sudo chmod g+x conf
$ sudo chown -R tomcat webapps/ work/ temp/ logs/
$ sudo update-java-alternatives -l
copy the location
$ sudo nano /etc/systemd/system/tomcat.service

After=network.target
[Service]
Type=forking
Environment=JAVA_HOME=paste the copied path
Environment=CATALINA_PID=/opt/tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/opt/tomcat
Environment=CATALINA_BASE=/opt/tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

ExecStop=/opt/tomcat/bin/shutdown.sh
User=tomcat
Group=tomcat

RestartSec=10
Restart=always
[Install]
WantedBy=multi-user.target
save the file
$ sudo systemctl daemon-reload
$ sudo systemctl start tomcat
$ sudo systemctl status tomcat
$ sudo ufw allow 8080
STEP 5 : MANAGE CREDENTIALS
$ sudo nano /opt/tomcat/conf/tomcat-users.xml
<tomcat-users . . .>
<user username="admin" password="password" roles="manager-gui,admin-gui"/>
</tomcat-users>
save and close
$ sudo systemctl restart tomcat

If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!
ReplyDeleteThis is the default Tomcat home page. It can be found on the local filesystem at: /var/lib/tomcat8/webapps/ROOT/index.html
Tomcat8 veterans might be pleased to learn that this system instance of Tomcat is installed with CATALINA_HOME in /usr/share/tomcat8 and CATALINA_BASE in /var/lib/tomcat8, following the rules from /usr/share/doc/tomcat8-common/RUNNING.txt.gz.
You might consider installing the following packages, if you haven't already done so:
tomcat8-docs: This package installs a web application that allows to browse the Tomcat 8 documentation locally. Once installed, you can access it by clicking here.
tomcat8-examples: This package installs a web application that allows to access the Tomcat 8 Servlet and JSP examples. Once installed, you can access it by clicking here.
tomcat8-admin: This package installs two web applications that can help managing this Tomcat instance. Once installed, you can access the manager webapp and the host-manager webapp.
NOTE: For security reasons, using the manager webapp is restricted to users with role "manager-gui". The host-manager webapp is restricted to users with role "admin-gui". Users are defined in /etc/tomcat8/tomcat-users.xml.
