This guide is for CentOS 7

=Step 0: Make sure Tomcat is not already installed=
Run as root
systemctl status tomcat

If you get an error saying there was no tomcat.service file found, then Tomcat has not yet been installed on this machine.

=Step 1: Make sure Java is running on your machine=

Check if java is already installed on your machine with
java -version

You should get something that looks similar to this:
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

If java is not installed run the following (as root):
yum install java-1.8.0-openjdk-devel

=Step 2: Download the latest version of Tomcat from the website=
https://tomcat.apache.org/download-90.cgi

==Copy the .tar.gz file into /tmp on your machine==

==Create tomcat user and directory==
Tomcat should not be run as root. Create a tomcat user with fewer privileges. This will also create the /opt/tomcat directory on the machine where all tomcat files will be stored
sudo useradd -m -U -d /opt/tomcat -s /bin/false tomcat

==Extract the contents of the tar.gz file==
As of the writing of this page, the latest version of Tomcat 9 is 9.0.30
tar -xvzf apache-tomcat-9.0.30.tar.gz

Move the extracted files to /opt/tomcat
sudo mv apache-tomcat-9.0.30 /opt/tomcat/

Optional: Create symbolic link for updates
ln –s /opt/tomcat/apache-tomcat-9.0.30 /opt/tomcat/latest

==Modify Tomcat User Permissions==
chown –R tomcat:tomcat /opt/tomcat
sh -c 'chmod +x /opt/tomcat/latest/bin/*.sh'

==Create a System Unit File==
Create the tomcat.service file
vim /etc/systemd/system/tomcat.service

Paste the below into the file
[Unit]
Description=Tomcat 9 servlet container
After=network.target
[Service]
Type=forking
User=tomcat
Group=tomcat
Environment="JAVA_HOME=/usr/lib/jvm/jre"
Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom"
Environment="CATALINA_BASE=/opt/tomcat/latest"
Environment="CATALINA_HOME=/opt/tomcat/latest"
Environment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms32G -Xmx32G -server -XX:+UseParallelGC"
ExecStart=/opt/tomcat/latest/bin/startup.sh
ExecStop=/opt/tomcat/latest/bin/shutdown.sh
[Install]
WantedBy=multi-user.target

Change the Xms and Xmx according to how much memory you want to provide to Tomcat.
Save and close the file.
