   sudo chmod -R g+r /opt/tomcat/conf
   sudo chmod g+x /opt/tomcat/conf
   sudo chown -R tomcat /opt/tomcat/webapps /opt/tomcat/work /opt/tomcat/temp /opt/tomcat/logs

7. Edit Tomcat startup script file:

   sudo vi /opt/tomcat/bin/startup.sh

   Add the following content at the beginning of the file:

   #!/bin/bashCATALINA_HOME=/opt/tomcat

   Save and close the file.

8. Set Tomcat to start automatically at boot:

   sudo vi /etc/systemd/system/tomcat.service

   Add the following:

   [Unit]Description=Apache TomcatAfter=syslog.target network.target[Service]Type=forkingUser=tomcatGroup=tomcatEnvironment=CATALINA_PID=/opt/tomcat/temp/tomcat.pidEnvironment=CATALINA_HOME=/opt/tomcatEnvironment='JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom'ExecStart=/opt/tomcat/bin/startup.shExecStop=/opt/tomcat/bin/shutdown.sh[Install]WantedBy=multi-user.target

   Save and close the file.

9. Start Tomcat service:

   sudo systemctl start tomcat
