Qwoynd Service File

It is best to run qwoynd as a system service. Please follow the instructions below to get a basic service running on your machine.

Create a file name qwoynd.service

cd ~
nano qwoynd.service

Next copy the contents of the following code block into your newly created file and make changes where appropriate.

[Unit]

[Service]
User=root
ExecStart=/root/go/bin/qwoynd start

Now that you have your system file created we will need to move and enable it.

mv qwoynd.service /etc/systemd/system/qwoynd.service
systemctl enable qwoynd
sudo systemctl daemon-reload

That's it! In order to run your service please type the following command.

sudo service qwoynd start

You can check your logs by running the following command.

journalctl -u qwoynd -f

Increase Number of Open Files

You may need to increase the number of allowed opened files in order for qwoynd to not crash. To do so please follow the steps below.

sudo su -c "echo 'fs.file-max = 65536' >> /etc/sysctl.conf"
sysctl -p

sudo su -c "echo '* hard nofile 94000' >> /etc/security/limits.conf"
sudo su -c "echo '* soft nofile 94000' >> /etc/security/limits.conf"

sudo su -c "echo 'root hard nofile 94000' >> /etc/security/limits.conf"
sudo su -c "echo 'root soft nofile 94000' >> /etc/security/limits.conf"

sudo su -c "echo 'session required pam_limits.so' >> /etc/pam.d/common-session"
