Introduction

Kiuwan on premise installer is a powerful tool that suits multiple environment scenarios:

• Single-host full contained installation.
• Multi-host installation where infrastructure services are externalized.
• Multi-host installation where kiuwan services are distributed (only AWS environments supported so far).
• Any combination of the two previous scenarios.

Depending on your needs, a different installation approach will be needed. Check this installation guide for details on how to proceed and find the solution that best fits your requirements.

System requirements

Installation requirements

It is mandatory for any host where a Kiuwan on premises service is installed to meet this requirements:

• Linux distribution
• Linux kernel version 3.10 or higher
• Connectivity to SMTP Mail Server.
• Internet connectivity during the installation process (see Installation guide).
• Installing user must be root or have sudo privileges.

These software is also needed:

• Docker CE >=19.03.2
• Docker-compose >= 1.24.1
• Java Runtime Environment >=8
• Openssl >= 1.0.2
• Unzip
• GNU tar

Needed internet connections

Please make sure your host machines have connection to this servers when installing Kiuwan on premises:

CPU and memory minimum requirements

The following table shows the minimum requirements for each service. Note that these are only minimum requirements. You should take care of giving each service enough resources depending on your system demands.

Note: CPU clock speed and disk speed will affect overal response time. 

With the configuration above a system with the following load should give continuous service without problems:

• Parallel processing of 2 analyses (any additional parallel analysis request will be enqueued, and it will be executed as soon as any of the running analyses finishes)
• 50 concurrent web users or REST API calls.

Given the table above, for a single-host installation where no service is externalized the minimum system requirements are:

• 14GB of RAM and a processor with 8 cores for Kiuwan on premises.

It is recommended that you overscale these characteristics for the OS to have resources available for itself.

The Kiuwan on premise installation tool (kiuwan-cluster)

Kiuwan on premise installation process is carried out by our "kiuwan-cluster" tool.

The tool is provided as a tar.gz file. The following table summarizes the resources you will find once the tool distribution is extracted:

The following sections will guide you through the installation process.

Installation: common steps

This guide will reference two important folders:

• [INSTALL_DIR]: where the installation tool (kiuwan-cluster) will be located.
• [VOLUMES_DIR]: where the persistent volumen will be located.

Sometimes this folders will be referenced inside command line examples. Please make sure you replace any of them with the needed real path.

Note that it is up to you where this folders will be located.

Step 1: download kiuwan-cluster

The first step is to download kiuwan-cluster, the Kiuwan on premises installation tool. It can be downloaded directly from a terminal like this:

wget https://static.kiuwan.com/download/onpremise/kiuwan-cluster.tar.gz

This will download to the current directory the latest available installation tool.

Step 2: untar kiuwan-cluster

Once downloaded you should untar the provided gz file:

tar xvzpf kiuwan-cluster_master.tar.gz

This will untar the installation tool to a folder with extended version information of the tool. For example:

/home/user/kiuwan-cluster_master.XXXX-2.8.YYMM.V

This folder will be referred to as [INSTALL_DIR] through this guide.

Step 3: copy license files

In order to be able to start a Kiuwan on premises installation, you will need two license files:

• configq1.zip
• license.zip

Copy these files to the user-content folder of your installation tool directory (please replace [INSTALL_DIR] with the real location of your installation directory):

cp configq1.zip [INSTALL_DIR]/user-content
cp configq1.zip [INSTALL_DIR]/user-content

Step 4: download and copy the needed driver version for MySQL

Kiuwan on premise needs this exact MySQL driver:

mysql-connector-java-5.1.39-bin.jar

You can download it by executing this command:

wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.39.tar.gz

Copy the downloaded jar file to the user content folder:

cp mysql-connector-java-5.1.39.tar.gz [INSTALL_DIR]/user-content

Step 5: initialize your volumes

The installation tool comes with the base volumes to boot a first installation of Kiuwan on premises. We provide three volumes:

• config-shared: contains the base configuration, shared between different services.
• data-shared: contains the base data structure, shared between different services.
• data-local: contains the base data structure, independent for each service.

Copy the provided volumes to a location of your desire:

sudo cp -rp [INSTALL_DIR]/volumes/config-shared [VOLUMES_DIR]/config-shared
sudo cp -rp [INSTALL_DIR]/volumes/data-shared [VOLUMES_DIR]/data-shared
sudo cp -rp [INSTALL_DIR]/volumes/data-local [VOLUMES_DIR]/data-local

Take note of the locations you choose for each volume. You will need these paths for the next installation step.

Step 6: configure the created volume paths

Edit the file located in [INSTALL_DIR]/config/volumes.properties and set the previous paths to each property:

config.shared=[VOLUMES_DIR]/config-shared
data.shared=[VOLUMES_DIR]/data-shared
data.local=[VOLUMES_DIR]/data-local

Please remember that [VOLUMES_DIR] here is just a placeholder for the real path you chose.

Step 7: configure your email server

Kiuwan needs an working and accessible e-mail server to send notifications.

Edit with your favourite editor the main configuration file, found in your [VOLUMES_DIR]:

sudo vim [VOLUMES_DIR]/config-shared/globalConfig.properties

Note that this is the file located in your [VOLUMES_DIR], not in the [INSTALLER_DIR], which only contains the base volumes.

Edit the following properties under the section named "Kiuwan instances shared configuration":

• kiuwan.mail.host: the host of your email server.

• kiuwan.mail.port: the port of your email server.

• kiuwan.mail.username: the username to use when authenticating with your email server.

• kiuwan.mail.password: the password to use when authenticating with your email server.

• kiuwan.mail.from: the email account to use as the sender.

• kiuwan.default.mail.account: the email account to set to your default Kiuwan user.

Installation: single-host and minimum configuration

Follow this section if you want to proceed and install Kiuwan on premise with no further customization.

The defaults will install Kiuwan on premise with these characteristics:

• Single-host installation, including this services (see System architecture for more details):
  • loadbalancer
  • 1 kiuwan front instance
  • 1 kiuwan analyzer instance
  • 1 kiuwan scheduler instance
  • mysql
  • redis
• HTTPS support when accessing Kiuwan and between the loadbalancer and kiuwan instances.
• Kiuwan on premises deployed in the default domain (https://kiuwan.onpremise.local).

If this is enough for you, just continue with the following steps.

Step 1: deploy user content

On a terminal, navigate to the [INSTALL_DIR] folder and execute this command:

sudo ./deploy-user-content.sh

This will copy the user-content files to the configured volumes and set the needed permissions.

Step 2: install Kiuwan on premises

On a terminal, navigate to the [INSTALL_DIR] folder and execute this command:

sudo ./install.sh

This will:

• Download and run the needed Docker images.
• Install the database resources for Kiuwan on premises.
• Download the latest available Local Analyzer, Engine and Kiuwan for Developers to make them available in your installation.
• Install the engine data in your Kiuwan on premises database.
• Autogenerate the needed configuration for each kiuwan instance.
• Run all the needed containers.

Once the installation is finisished please refere to the Installation guide section.

Accessing your Kiuwan on premises installation

To access your Kiuwan on premises installation you should take into account whether the selected domain is available in the DNSs your local network may use.

In order to access Kiuwan you will need to do one of the following options:

• Add kiuwan.onpremise.local to your DNS (recommended option).
• Add kiuwan.onpremise.local to your hosts file.

For testing purposes or if you choose the second option, edit this file in the host where you plan to access Kiuwan from:

• Windows OS: C:\Windows\System32\drivers\etc\hosts
• Linux OS: /etc/hosts

Add the following entry to the previous file:

[kiuwan_on_premise_host_ip] [kiuwan_on_premise_host]

For example, the previous entry may look like this for an installation pointing to the default host (note that the IP of the example may change in your local network):

192.168.0.56 kiuwan.onpremise.local

Once the previous steps have been done, you should be able to access Kiuwan on premises entering your Kiuwan host in your browser:

Handling trusted certificates warning messages in your browser   and clients
 

Kiuwan on premises installer tool provides default certificates for the default host name, signed by a supplied CA (Certificate Authority).

The CA public certificate is provided in this file:

• [INSTALL_DIR]/ssl/ca/cacert.pem

In order to make your browser trust the supplied certificates, you will need to add this CA to your browser, and Java clients that access your Kiuwan on premises installation:

• Fixefox, Chrome, Edge: import cacert.pem by using the tools provided by the browsers.
• Java clients (Kiuwan for developers Eclipse, Kiuwan for developers JetBrains, Jenkins, KLA, etc): add the provided cacert.pem to the JRE keystore used by the client. Please refer to the official documentation of your JRE distribution about the Java keytool program.
• Windows clients (Kiuwan for developers VisualStudio): import cacert.pem by using the tools provided by Windows (certmgr.msc).
• Multiplatform clients (Kiuwan for developers VisualStudioCode): import cacert.pem by using the tools provided by your OS.
