How to install tomcat web server in a portable way?

Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages, Java Expression Language and WebSocket technologies. Tomcat provides a "pure Java" HTTP web server environment in which Java code can run. In this post i will discuss how to install tomcat in a portable manner.

Step-01: Create Tomcat user

# useradd -s /sbin/false tomcat

# echo "password" | passwd tomcat --stdin

Step-02: Create Environment for Tomcat user

# mkdir /home/tomcat/APACHE

# mkdir /home/tomcat/JAVA

Step-03: Download Tomcat and JAVA from below URL

cd /home/tomcat/APACHE

Download your desire version from below link:

Tomcat: https://tomcat.apache.org/

JAVA: https://www.oracle.com/java/technologies/javase-jre8-downloads.html

# tar -xvf apache-tomcat-8.5.57.tar.gzip

# cd /home/tomcat/JAVA

# tar -xvf jre-8u102-linux-x64.tar.gzip

Step-04: Install Tomcat and JAVA

# ln -s /home/tomcat/APACHE/apache-tomcat-8.5.57 /home/tomcat/APACHE/apache-tomcat

# ln -s /home/tomcat/JAVA/jre1.8.0_102 /home/tomcat/JAVA/jre

# cd /home/tomcat

# chown -R tomcat:tomcat *

# vim /home/tomcat/.bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH

# Environment for tomcat user
export JRE_HOME=/home/tomcat/JAVA/jre
export CLASSPATH=$CLASSPATH:$JRE_HOME/lib
export PATH=$JRE_HOME/bin:$PATH:$HOME/bin

Load the bash profile

# source /home/tomcat/.bash_profile

Step-05: Create Startup Systemd Script for RHEL / CentOS 7~8

# vim /etc/systemd/system/tomcat.service

[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target

[Service]
Type=forking

Environment=JAVA_HOME=/home/tomcat/JAVA/jre
Environment=JRE_HOME=/home/tomcat/JAVA/jre
Environment=CATALINA_PID=/home/tomcat/APACHE/apache-tomcat/temp/tomcat.pid
Environment=CATALINA_HOME=/home/tomcat/APACHE/apache-tomcat
Environment=CATALINA_BASE=/home/tomcat/APACHE/apache-tomcat
Environment='CATALINA_OPTS=-Xms512M -Xmx5120M -server -XX:+UseParallelGC'
Environment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'

ExecStart=/home/tomcat/APACHE/apache-tomcat/bin/startup.sh
ExecStop=/home/tomcat/APACHE/apache-tomcat/bin/shutdown.sh

User=tomcat
Group=tomcat

[Install]
WantedBy=multi-user.target

# systemctl daemon-reload

# systemctl start tomcat

# systemctl enable tomcat

Step-05: Create Startup Systemd Script for RHEL / CentOS 6

init.tomcat.txt

Download TXT • 2KB

Download above script into /etc/init.d/ directory then follow steps:

# mv /etc/init.d/init.tomcat.txt /etc/init.d/init.tomcat

# chmod +x /etc/init.d/init.tomcat

# /etc/init.d/init.tomcat start

# chkconfig --level 3,5 init.tomcat on

That's it.

Hope this will help.
