This is an easy process and everyone should be able to do this. Windows and Macintosh users should be able to install YaCy in the same way as they install any other application.

On Windows

• Install Java 8 from https://www.java.com/en/download/manual.jsp
• Install YaCy by double-clicking the downloaded installer
• When the message "Windows protected your PC (in Windows 10) appears, klick "More info", then "Run anyway". When asked "Do you want to allow this app from an unknown publisher to make changes to your device", klick "yes".
• Within the YaCy Installer, klick "Next", "I Agree", "Next", "Install", "Finish"
• To run YaCy, just double-click the YaCy App Icon (which may be on your desktop)
• YaCy is then running on port 8090; i.e. open http://localhost:8090 in your browser

On Macintosh

• Install Java 8 from https://www.java.com/en/download/manual.jsp
• Double-Click the downloaded .dmg-File and copy the YaCy App out of the mounted drive into your Application folder
• To run YaCy, just double-click the YaCy App Icon in your Application Folder
• YaCy is then running on port 8090; i.e. open http://localhost:8090 in your browser

On Linux and any other Operation Systems

If you know how to install Java on your computer and how to start a shell script, the process is very simple:

• Install JDK 8 (Oracle or OpenJDK)
• Download and decompress the tarball
• Run startYACY.sh inside your decompressed folder

This can be done by running in a terminal:

sudo apt-get update
sudo dpkg --configure -a
sudo apt-get install -y openjdk-8-jdk
wget http://latest.yacy.net/yacy_v1.922_20191013_9964.tar.gz
tar xfz http://latest.yacy.net/yacy_v1.922_20191013_9964.tar.gz
cd yacy
./startYACY.sh

• YaCy is then running on port 8090; i.e. open http://localhost:8090 in your browser
• no password is required when accessing this YaCy instance from localhost
• for headless operation, set the password on the host console with bin/passwd.sh <password>

Compile YaCy yourself

You can download and build your own YaCy with these simple steps. You need:

• jdk-8 installed (Oracle Java 8 or OpenJDK 8)
• ant
• git

then do:

git clone https://github.com/yacy/yacy_search_server.git
cd yacy_search_server
ant clean all dist

The compiled tarball in then in the RELEASE folder.
