Page Contents

1. Prerequisites

  1. Install Java (refer to the System Requirements for supported versions)
  2. Install unzip

2. Installation Tasks

  1. Extract the turnkey installation archive to the desired location on the server. For example:
    1. $ mkdir /opt/enPortal
    2. $ cd /opt/enPortal
    3. $ unzip
  2. Save your license file into [INSTALL_HOME]/server/webapps/enportal/WEB-INF/config/
  3. Run the post installation tasks.

3. Post Installation Tasks

On Linux and UNIX systems, it is necessary to run a script to update file ownership and permissions, and set some initial configuration parameters. To be prepared to run this script, make sure you know which java you want enPortal to use (e.g. /usr/bin/java), what user to run enPortal as, and whether you wish to install a system service to automaticaly start/stop enPortal on boot and shutdown.

This script can be run as root or non-root. When run as non-root some options are not available, such as installing a system service.

  1. Change into the [INSTALL_HOME]/server/bin/helpers directory
  2. Run: $ ./
    if this script is not set executable, then run and try again: $ chmod u+x
  3. Answer the prompted questions. Defaults or previous preferences are provided where appropriate.
  4. The script will verify selected options before making any changes, so review and continue if correct.
  5. [optional] Make changes to the default ports, java memory tuning, and runtime options. Refer to the Runtime Options page for further information. Please note that some runtime options are managed by the post_install script.
  6. [optional] enPortal comes with a pre-configured H2 database for storing configuration. An external configuration database can also be used, see the Configuration Database page for more information.

3.1. post_install Details

The post_install script manages the following environment variables which are updated into It is recommended to re-run post_install to make changes to these:


JAVA_HOME is a very important setting and is stored within setenv-custom to ensure a consistent environment whether running, running enPortal from the command line, or running enPortal as a service.

post_install will determine JAVA_HOME based on the following rules:

  1. The current setting from setenv-custom
  2. If above is not set, or invalid, then JAVA_HOME from the user's environment
  3. If above is not set, or invalid, then based on the user's PATH ($ which java)
  4. Finally, the user is prompted to enter an alternative location.

Due to how Java runtime environments are managed on the various Linux / UNIX systems, the script also completely resolves any symbolic links. This may explain why a simple Java path such as /usr/bin/java can be saved as a more involved JAVA_HOME into After running post_install it's always possible to edit setenv-custom and set a different JAVA_HOME if necessary.

4. Verifying the Installation

  1. Start enPortal:
    • If a system service was installed, then use the appropriate command to start, such as $ service service_name start for RedHat Enterprise Linux
    • Or start on the command line from the [INSTALL_HOME]/server/bin directory: ./
  2. Any errors will be logged into [INSTALL_HOME]/server/logs
  3. Go to the following URL in a web browser, using a system that has network access to the server: http://server_ip:8080. If the system started correctly, a login page will be displayed.
    • The default login credentials are: administrator / administrator / System

5. Additional Configuration Options

5.1. Starting on Boot

To have enPortal start and stop automatically on boot and shutdown, it is necessary to use a system service. The Post Installation script will handle setting up and configuring the system service on supported platforms.

NOTE: if the enPortal installation directory has to be moved, or enPortal is to be removed, then make sure to remove the system service first. This can be done using the unix services utility as root from the [INSTALL_HOME]/server/bin/helpers directory: $ ./ remove

5.2. Binding to Port <1024 as non-root

If enPortal is not running as root, Tomcat will not be able to bind to a port less than 1024. By default, enPortal is configured to listen on port 8080 so this is not an issue. However in production systems it may be necessary to have enPortal listen on a port < 1024 and have enPortal run as non-root. In these situations, the following options apply:

  1. Use JSVC to run enPortal. This allows JSVC to run as root, bind to the port, and then start Tomcat as the non-root user. To configure JSVC, run the Post Installation script and answer yes to the question about using JSVC. To change the listening port then edit the HTTP_PORT value in (see Runtime Options). It will be necessary to restart enPortal for these changes to take effect.
    NOTE: in some cases the included JSVC binary may not work and will need to be re-compiled to suit your platform/configuration (see
  2. Use OS-supported port forwarding. Depending on the platform, the operating system may offer network layer port forwarding to transparently route traffic from the desired port to the port enPortal is listening on.
    • Example for Linux using iptables. This will redirect port 80 to port 8080 arriving on the eth0 interface. Add this command to /etc/rc.local to enable on boot:
      iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
    • Example for Solaris using ipfilter. This will redirect port 80 to port 8080 for traffic on the e1000g0 interface which has IP
      1. create /etc/ipf/ipnat.conf if it does not exist, and add the line:
        rdr e1000g0 port 80 -> port 8080 tcp
      2. enable the ipfilter system service: $ svcadm enable ipfilter. This will ensure the service is enabled at boot.
      3. verify the forwarding rules: $ ipnat -l

5.3. 64-bit Java on Solaris

Java for Solaris is packaged differently than for other platforms in that both 32-bit and 64-bit JVMs exist in the same location. In order to use the 64-bit VM it's necessary to either specify the -d64 option, or to explicitly run the 64-bit executable (for example: /opt/java8/bin/amd64/java).

For the best results with enPortal do the following:

  • For default (non-jsvc) installs edit and add the following:
  • If using JSVC just ensure [INSTALL_HOME]/server/bin/jsvc links to the 64-bit executable. Do not set the variable above as this option is not valid to the jsvc executable.

5.4. Restoring an Archive

The instructions above detail the procedures for a new installation. However, when restoring or applying an archive (see Backup and Recovery) it actually replaces files on the filesystem and you must review:

  1. If using a Restore then is replaced
  2. If using a Restore the license file may be replaced
  3. Both Restore and Apply cases may include files with incorrect permissions and/or ownership

The recommendation whether restoring with a Restore or Apply is to re-run after the import completes. In cases where the archive originates from a different system then Apply is the recommended import command.

6. Stopping enPortal

To stop enPortal, terminate the Tomcat process that is running on the enPortal server.

When enPortal is stopped, all current users who are logged in to the system will receive an error message the next time they make a request to the enPortal server. Subsequent users will not be able to access the login page until enPortal is restarted. If you are stopping a production instance of enPortal, it is recommended that you schedule a maintenance window and send advance notification to users of the system. You can check if there are any active users logged in to enPortal before stopping it by using the Session Manager.
  • For instances running as a system service make sure it is shutdown as a service, i.e.
    $ service service_name stop or
    $ /etc/init.d/enPortal stop
  • When running on the command line then use:
  • When running attached to the console (./ run) then use a CTRL+C signal to terminate.
  • As a general alternative locate the process and send a TERM signal.

You must properly shut down Tomcat. Do not kill the process by clicking the window "close" button ("X") or by using the Unix kill command (kill -9 <processid>). If the database does not properly shut down, residual lock files have been documented to cause problems when restoring archives.
