Set the tomcat8 service to start on boot.

Run the following command to reload the changed service configurations.

The script drops privilege to the tomcat user in order to start and stop the tomcat8 service.Ĭhown root:root /etc/systemd/system/rviceĬhmod 700 /etc/systemd/system/rvice This script needs to be owned by root and executable in order to run as a service. Have a look at the recommended memory allocation settings in this article. This is updating the heap size values in CATALINA_OPTS. Edit this script with your minimum and maximum memory for the Tomcat 8.5 application.Save this file as /etc/systemd/system/rvice. If your Java installation is in a different location please change the value of the JAVA_HOME variable accordingly. Edit tomcat's ~/.profile file and add these lines at the end.Your current user password may be requested if you are not logged in as root. In order to start the tomcat server, the tomcat user needs to have some variables set. The install directories need to be owned by the tomcat user and group.Ĭhown -R tomcat:tomcat /usr/share/tomcat8Ĭhown -R tomcat:tomcat /usr/share/apache-tomcat-8.5.34 Useradd -g tomcat -s /bin/bash -c 'Tomcat user' -d /usr/share/tomcat8 tomcat The init script drops privilege to this user before running the tomcat8 daemon. This is a better security situation than running it as root. The tomcat8 service will 'run as' and be owned by the tomcat user and group. We can now reference Tomcat 8.5 from this 'new' location: /usr/share/tomcat8. We simply install the new Tomcat in a new directory and delete and recreate the Tomcat 8.5 symlink to point at this new directory.

By creating a symlink to the 'real' tomcat directory, we can update the Tomcat instance without having to change every script that references it. Tar -zxvf apache-tomcat-8.5.34.tar.gz -C /usr/share/

Untar the files you have downloaded into the /usr/share directory.

This guide also assumes your file is apache-tomcat-8.5.34. Your system's package manager may be used to install Tomcat 8.5 automatically however, this guide assumes you are doing so manually.
