Installation of YaCy on Debian
Installation on Debian-based GNU/Linux operating systems is easy using our Debian repository:
http://debian.yacy.net
TODO: not any more!
Create a debian source list file for YaCy sources:
echo 'deb http://debian.yacy.net ./' > /etc/apt/sources.list.d/yacy.list
Install the developer key with one of the two next methods
wget http://debian.yacy.net/yacy_orbiter_key.asc -O- | apt-key add -
apt-key advanced --keyserver pgp.net.nz --recv-keys 03D886E7
And finally install YaCy itself. Warning! If you will be using Tor, it is important to read YaCy and Tor before taking the next step! Tor must be configured for YaCy before YaCy runs for the time. Running "apt-get install yacy" before setting up Tor will create a state for which there is no documentation to recover from.
apt-get update
apt-get install openjdk-7-jre-headless # java 7 is sufficient, only a headless version is needed
apt-get install yacy
Important File Locations
After the installation, the yacy application path is:
/usr/share/yacy
The DATA-path is:
/var/lib/yacy
The configuration files should be here:
/etc/yacy/
/etc/yacy/yacy.conf is created using the /usr/share/yacy/defaults/yacy.init file on the first run.
The log files should be here:
/var/log/yacy/
Managing YaCy
When you have installed YaCy using the Debian repository, YaCy is started automatically after a OS startup, and stopped before shutdown.
You can also start and stop YaCy from the command line with: (must be run as root)
/etc/init.d/yacy stop
/etc/init.d/yacy start
/etc/init.d/yacy restart
You can use systemctl (run as root) to enable or disable YaCy automatic startup at boot.
Enable automatic startupĀ :
systemctl enable yacy
Disable automatic startupĀ :
systemctl disable yacy
The YaCy web server runs on port 8090 by default. The administration pages are at
http://localhost:8090/
but you can also set any other port for the interface using the administration pages of YaCy. A Port 80 is possible, but it is better to get access to this port using a Portforwarding.
Changing password: If you do not set a username and password during
installation, the username will be "admin" and the password will be
randomly generated. You can still run a yacy node this way, but it won't
have the potential to be as useful since you won't be able to change
password-protected settings. Access the password-protected parts by
changing the password manually in a terminal. You can do this by going
to /usr/share/yacy/bin and running ./passwd.sh <new password>
(Note:
your new password will appear in plain text in the terminal).
cd /usr/share/yacy/bin
./passwd.sh <new password>
Automatic Updates
When configured this way, the YaCy-internal auto-updater does not work. An automatic update must be done with OS tools. i.e. with a crontab command. An example for that is the following line, which you must write into /etc/crontab
0 6 * * * root apt-get update && apt-get -y --force-yes install yacy
In Ubuntu, the above line is only valid for the system crontab file (located at /etc/crontab) - you can edit this file on newer Ubuntu OS directly without using the crontab command. Below are comments from the file in Ubuntu 12.04:
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
If you want to use the root user crontab in Ubuntu instead, an example would be:
username@hostname:~$ sudo crontab -e
no crontab for root - using an empty one
Select an editor. To change later, run 'select-editor'.
1. /bin/ed
2. /bin/nano <---- easiest
3. /usr/bin/vim.basic
Choose 1-3 [2]: <enter>
Then add the following at the end of the file:
0 6 * * * /usr/bin/apt-get update && /usr/bin/apt-get -y --force-yes install yacy
Please note, there is no user name on the line above, and absolute (full) paths are used here to prevent binary location problems!
Next Steps
After you configured YaCy, you may also want to set a static IP to get a unique IP to your YaCy peer.
