- Set port variable
- Install and configure authbind
- Update firewall rule
- Overwrite zend systemd unit files and reload the daemon
- Replace port 9033 with new port in zen.conf
- Restart zend and zentracker
NOTE: After executing the following steps for this guide, if you have a need to run zend manually, you will need to instead use the following: authbind --deep /usr/bin/zend
- If you need to run zend manually or need to run a rescan or reindex, those would be accomplished as follows
- authbind --deep /usr/bin/zend
- authbind --deep /usr/bin/zend --rescan
- authbind --deep /usr/bin/zend --reindex
| Description | Command | |
|---|---|---|
| 1 | Set a port variable, replace <port> with your port number, remove <brackets> | PORT=<port> |
| 2 | Install and configure authbind using the custom port set in the previous step | sudo apt-get install authbind -y sudo touch /etc/authbind/byport/$PORT sudo chown $USER /etc/authbind/byport/$PORT chmod 755 /etc/authbind/byport/$PORT |
| 3 | Add your port to your firewall rule set | sudo ufw allow $PORT/tcp |
| 4 | Overwrite existing zend systemd unit file, copy and paste the entire block of text | echo \ "[Unit] Description=Zen daemon [Service] User=$USER Type=forking ExecStart=/usr/bin/authbind --deep /usr/bin/zend -daemon -pid=$HOME/.zen/zend.pid PIDFile=$HOME/.zen/zend.pid Restart=always RestartSec=10 [Install] WantedBy=multi-user.target" | sudo tee /lib/systemd/system/zend.service |
| 5 | Overwrite existing zenupdate systemd unit file, copy and paste the entire block of text | echo \ "[Unit] Description=zenupdate.service [Service] Type=oneshot ExecStart=/usr/bin/certbot -q renew --pre-hook 'systemctl stop zend' --post-hook 'systemctl start zend' PrivateTmp=true" | sudo tee /lib/systemd/system/zenupdate.service |
| 6 | Overwrite existing zenupdate timer systemd unit file, copy and paste the entire block of text | echo \ "[Unit] Description=Run zenupdate unit twice a month @ 06:00:00 (UTC) [Timer] OnCalendar=*-*-01 06:00:00 OnCalendar=*-*-03 06:00:00 Unit=zenupdate.service Persistent=true [Install] WantedBy=timers.target" | sudo tee /lib/systemd/system/zenupdate.timer |
| 7 | Reload the systemd daemon to load the changes | sudo systemctl daemon-reload |
| 8 | Replace port 9033 with new port in zen.conf | sed -i "s/port=9033/port=$PORT/g" ~/.zen/zen.conf |
| 9 | Remove the old 9033 firewall rule | sudo ufw delete allow 9033/tcp |
| 10 | Restart zend and zentracker | sudo systemctl restart zend zentracker |
