How to Install Fess on OpenBSD

This tutorial will guide you on installing Fess on an OpenBSD system. Fess is a search engine platform based on Elasticsearch.

Prerequisites

Before we proceed with the installation, make sure the following prerequisites are met:

• A running instance of OpenBSD.
• An account with sudo privileges.

Step 1: Update the System

First, update the OpenBSD system to ensure that all the packages are up to date.

sudo pkg_add -u

Step 2: Install Dependencies

Next, install the following dependencies:

• Elasticsearch
• Java Development Kit (JDK)

To install Elasticsearch:

sudo pkg_add elasticsearch
sudo rcctl enable elasticsearch
sudo rcctl start elasticsearch

To install the JDK:

sudo pkg_add openjdk

Step 3: Download and Install Fess

1. Download the latest version of Fess from https://fess.codelibs.org/.
2. Extract the archive.

tar -xzvf fess-x.x.x.tar.gz

3. Move the extracted directory to the /usr/local directory.

sudo mv fess-x.x.x /usr/local

Step 4: Configure Fess

1. Navigate to the Fess installation directory.

cd /usr/local/fess-x.x.x/

2. Edit the fess.in.sh file.

sudo nano fess.in.sh

3. Set the FESS\_JAVA\_OPTS environment variable to use the OpenJDK.

FESS\_JAVA\_OPTS="-Xms512m -Xmx1g -Djava.awt.headless=true -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -Djna.nosys=true -XX:-OmitStackTraceInFastThrow -Dfile.encoding=UTF-8 -Djavax.net.ssl.trustStore=/usr/local/share/certs/ca-root-nss.crt -Djdk.http.auth.tunneling.disabledSchemes= -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/fess/heapdump.hprof -Djava.security.policy==/usr/local/fess-x.x.x/plugin.security.policy"

JAVA\_HOME=/usr/local/jdk-11/

PATH=$PATH:$JAVA\_HOME/bin

export PATH JAVA\_HOME FESS\_JAVA\_OPTS

4. Save and exit the file.

5. Edit the fess\_config.properties file.

sudo nano /usr/local/fess-x.x.x/app/WEB-INF/classes/fess\_config.properties

6. Configure the Elasticsearch server.

# Elasticsearch property
elasticsearch.host=localhost
elasticsearch.port=9200

7. Save and exit the file.

Step 5: Start Fess

1. Start Fess using the following command.

sudo /usr/local/fess-x.x.x/bin/fess start

2. Verify that Fess is running by accessing http://localhost:8080/ in a web browser.

Conclusion

Congratulations! Fess has now been successfully installed on your OpenBSD system. You can now proceed to configure it to meet your specific search engine requirements.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
