How to Install Yacy on Alpine Linux Latest

Yacy is a decentralized, peer-to-peer search engine that can be installed on your own computer or server. In this tutorial, we will walk you through the steps of installing Yacy on Alpine Linux Latest.

Prerequisites

Before we begin, make sure you have the following:

  • A server or computer running Alpine Linux Latest
  • A basic knowledge of the command line

Step 1 — Updating Alpine Linux

First, make sure your system is up to date by running the following command:

$ sudo apk update && sudo apk upgrade

Step 2 — Installing Java

Yacy requires Java, so we need to install it first. Run the following command to install OpenJDK 11:

$ sudo apk add openjdk11

Step 3 — Downloading Yacy

Run the following command to download the latest version of Yacy:

$ wget https://yacy.net/release/yacy_grid_loader.jar

Step 4 — Running Yacy

To run Yacy, use the following command:

$ java -jar yacy_grid_loader.jar

The first time you run Yacy, it will ask you a series of questions to configure the search engine. Follow the prompts to set up your Yacy instance.

Step 5 — Accessing Yacy

To access the Yacy web interface, open your web browser and navigate to http://localhost:8090. You should see the Yacy search engine interface, where you can search and configure your Yacy instance.

Step 6 — Starting Yacy on Boot

To ensure that Yacy runs automatically when your system starts up, we need to create a systemd service.

First, create a new file called yacy.service in the /etc/systemd/system/ directory using the following command:

$ sudo nano /etc/systemd/system/yacy.service

Copy and paste the following code into the file:

[Unit]
Description=Yacy P2P Web Search Engine
After=syslog.target network.target

[Service]
Type=simple
User=yacy
ExecStart=/usr/bin/java -Xms1500m -Xmx1500m -jar /var/local/yacy/startYACY.sh
ExecReload= /usr/bin/kill -HUP $MAINPID
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

Save and close the file, then start the service by running the following commands:

$ sudo systemctl daemon-reload
$ sudo systemctl start yacy

To ensure that the service starts automatically on boot, run the following command:

$ sudo systemctl enable yacy

Congratulations! You have successfully installed and configured Yacy on Alpine Linux Latest.
