Installing nevisAdapt

Hardware recommendations

We recommend running nevisAdapt on a system with at least 4 CPU cores and 8 GB of RAM.

caution

If you use the extended version of the Geolocation database (which also includes the GPS coordinates), it is recommended that you allocate at least 5 GB memory for the nevisAdapt service. The size of the database file should be less than 500 MB.

The installation of the nevisAdapt service includes the following software packages:

Package name	Component	Remarks
nevisadapt-<version>.noarch.rpm	nevisAdapt service	- Contains an embedded Tomcat servlet container.- Contains the database schema.
nevisdetectcl-<version>.noarch.rpm	nevisAdapt AuthStates	Contains the AuthStates DeviceCookieAuthState and NevisAdaptAuthState.

Install all software packages with the user "nvauser " and the group "nvbgroup". As a precondition, this user and group must exist.

Software package installation - nevisAdapt service

To install the nevisAdapt service, proceed with the next steps.

The installation of the nevisAdapt plug-in is described further below.

1. Execute the following commands to install the component's software package:

rpm -i nevisadapt-<version>.noarch.rpm
rpm -i nevisdetectcl-<version>.noarch.rpm

During the installation, the following happens:

• Registration of the component as init.d service with the name nevisadapt.

• Creation of the spool directory structure (if not already existing).

• Extraction of the following files from the file /opt/nevisadapt/bin/nevisadapt-exec.jar:

  • /var/opt/nevisadapt/conf.properties
  • /var/opt/nevisadapt/conf/nevisadapt-exec.conf
  • /var/opt/nevisadapt/conf/logback.xml

2. Administer the component with the following commands:

service nevisadapt start
service nevisadapt status
service nevisadapt stop
service nevisadapt restart

The configuration of the runtime environment of a service is located in the file nevisadapt-exec.conf.

The following sample code block illustrates the installation of the nevisAdapt service:

Installation of the nevisAdapt service

# variables used by the exec /opt/nevisadapt/bin/nevisadapt-exec.jar used by init.d
APP_NAME=nevisadapt
JAVA_OPTS="-Xmx1024M -XX:+UseConcMarkSweepGC -Dlogback.configurationFile=/var/opt/nevisadapt/conf/logback.xml"
LOG_FOLDER=/var/opt/nevisadapt/logs
LOG_FILENAME=nevisadapt.stdout
  
# variables used by the application i.e. logback and spring
export NEVISADAPT_SPOOL_DIR=/var/opt/nevisadapt
export NEVISADAPT_APP_NAME=nevisadapt

Uninstalling the software package

To uninstall the nevisAdapt components, run the following commands:

rpm -e nevisadapt-<version>.noarch
rpm -e nevisdetectcl-<version>.noarch

During the uninstalling process, the service is stopped and deregistered. The spool directory is not modified, so a subsequent installation will have the same configuration.
