Installation
Installation is very easy on any system. If it looks complex here it's just because we give directions in great detail.
Compile YaCy yourself
You can download and build your own YaCy with these simple steps. This is probably the best and easiest ways for everyone who knwos how to use a command line interface. You need:
- jdk-8 installed (Oracle Java 8 or OpenJDK 8)
- ant
- git
Then run:
git clone https://github.com/yacy/yacy_search_server.git
cd yacy_search_server
ant clean all dist
The compiled tarball will then be in the RELEASE
folder.
To start YaCy from your compiled code, simply run:
./startYACY.sh
YaCy for Windows
- IMPORTANT Install Java 8 from https://adoptopenjdk.net/ first.
- Download YaCy for Windows from https://download.yacy.net/yacy_v1.924_20201214_10042.exe
- 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, double-click the YaCy app icon (which may be on your desktop).
- Whenever the following dialog appears click "allow private networks" and "allow access"
- YaCy is then running on port 8090 on your machine. Open http://localhost:8090 in your web-browser.
YaCy for Linux and other OS
You must install Java 8 on your computer if you don't have it already, and start the YaCy start shell script. YaCy can run under a normal user account, no root rights are needed if Java 8 is already installed.
- Install JDK 8 (Oracle or preferably OpenJDK). You get Java for Linux from https://adoptopenjdk.net/ but you should follow the installer package system that comes with your linux distribution.
- Download generic YaCy from https://download.yacy.net/yacy_v1.924_20210209_10069.tar.gz, i.e. by
wget https://download.yacy.net/yacy_v1.924_20210209_10069.tar.gz
- Unpack the tarball.
tar xfz yacy_v1.924_20210209_10069.tar.gz
- Run
startYACY.sh
inside your decompressed folder.
cd yacy
./startYACY.sh
Installing from start to finish would look something like this, depending on your distro.
sudo apt-get update
sudo dpkg --configure -a
sudo apt-get install -y openjdk-8-jre-headless
wget https://download.yacy.net/yacy_v1.924_20210209_10069.tar.gz
tar xfz yacy_v1.924_20210209_10069.tar.gz
cd yacy
./startYACY.sh
- YaCy is now running on port 8090 on your machine. Open http://localhost:8090 in your web-browser.
- No password is required when accessing this YaCy instance from localhost.
- Headless operation can be achieved by setting a password on the host console with
bin/passwd.sh <password>
.
On Macintosh
- Install Java 8 from https://adoptopenjdk.net/.
- Download YaCy for MacOS from https://download.yacy.net/yacy_v1.924_20201214_10042.dmg
- 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 now running on port 8090 on your machine. Open http://localhost:8090 in your web-browser.
Docker
Running YaCy in docker is easy. If you don't hava docker installed, get it from https://docs.docker.com/get-docker/ (for Mac, Windows and Linux) or read the instructions from https://www.docker.com/blog/getting-started-with-docker-for-arm-on-linux/ to install docker on Raspberry Pi or any other ARM-based devices.
The Official YaCy Images are hosted on Dockerhub at https://hub.docker.com/r/yacy/yacy_search_server
We provide amd64, arm64v8 and arm32v7 versions with the following tags:
- amd64:
yacy/yacy_search_server:latest
- arm64v8:
yacy/yacy_search_server:aarch64-latest
- arm32v7:
yacy/yacy_search_server:armv7-latest
i.e. to install YaCy in intel-based environmnts, run:
docker run -d --name yacy_search_server -p 8090:8090 -p 8443:8443 -v yacy_search_server_data:/opt/yacy_search_server/DATA --restart unless-stopped --log-opt max-size=200m --log-opt max-file=2 yacy/yacy_search_server:latest
then open http://localhost:8090 in your web-browser.
The default login for YaCy on Docker is admin
:yacy
To upgrade YaCy, follow the default upgrade pattern for docker images, i.e.
docker stop yacy_search_server
docker rm yacy_search_server
docker pull yacy/yacy_search_server:latest
.. and restart the container with the same command that you used initially to run the container, i.e. (like above)
docker run -d --name yacy_search_server -p 8090:8090 -p 8443:8443 -v yacy_search_server_data:/opt/yacy_search_server/DATA --restart unless-stopped --log-opt max-size=200m --log-opt max-file=2 yacy/yacy_search_server:latest
This will mount the data volume from the upgraded yacy instance.
Configuration with Environment Variables
All of the environment variables (see https://github.com/yacy/yacy_search_server/blob/master/defaults/yacy.init ) can be overwritten with the docker run
command. The environment variables are named like those in the yacy.init
files, with all .
(dot) replaced with _
(underscore), all uppercase and prefixed with YACY_
.
For example: the default peer name can be set with network.unit.agent
in yacy.init
. To pre-set this value during docker run
time, set the environmnt variable YACY_NETWORK_UNIT_AGENT
. The correspondig run command would be:
docker run -d --name yacy_search_server -p 8090:8090 -p 8443:8443 -e YACY_NETWORK_UNIT_AGENT=Choomba -v yacy_search_server_data:/opt/yacy_search_server/DATA --restart unless-stopped --log-opt max-size=200m --log-opt max-file=2 yacy/yacy_search_server:latest
This can also be used to re-start a previously started image to overwrite the already stored configuration values.
Backup and restore of DATA folder
All data from YaCy is written into the data folder which is stored in the docker volume yacy_search_server_data
. To back-up that DATA folder to /tmp/DATA.tar.gz
, just run
docker stop yacy_search_server
docker run --rm -v yacy_search_server_data:/opt/yacy_search_server/DATA -v /tmp:/tmp openjdk:8-stretch bash -c "cd /opt/yacy_search_server && tar -cf - DATA | xz -q -3v -T0 > /tmp/DATA.tar.xz"
docker start yacy_search_server
To restore the DATA folder from /tmp/DATA.tar.gz
, run
docker stop yacy_search_server
docker run --rm -v yacy_search_server_data:/opt/yacy_search_server/DATA -v /tmp:/tmp openjdk:8-stretch bash -c "cd /opt/yacy_search_server && rm -rf DATA/* && tar xf /tmp/DATA.tar.xz"
docker start yacy_search_server
Kubernetes
# optional: for a quick and easy installation of Kubernetes, run minikube
minikube start
minikube dashboard
# optional: if you want to run YaCy in a new namespace (does not work with minikube dashboard)
kubectl create namespace searchlab
kubectl config set-context --current --namespace=searchlab
# create deployment
kubectl create deployment yacy --image=yacy/yacy_search_server:latest --replicas=1 --port=8090
kubectl get deployment yacy -o wide # optional: show attributes of deployment
kubectl logs -f deployment.apps/yacy # optional: show logs of deployment
# create service
kubectl create service nodeport yacy --node-port=30890 --tcp=8090:8090
kubectl get service yacy -o wide # optional: show service configuration
# optional: access service in minicube
minikube service list
minikube service yacy
minikube service yacy -n searchlab # in case you are running in namespace 'searchlab'
# optional: shut down the YaCy deployment
kubectl delete service yacy
kubectl delete deployment yacy
# optional: switch back to default namespace
config set-context --current --namespace=default
Any OS with Java 8
