If BitNinja can not start, but it shows as another instance is running, it is because of a former pid file.
- Just echo an empty string to the file.
echo "" > /var/lib/bitninja/blue.pid.
- Try to start the BitNinja agent with
service bitninja startcommand
If that does not work for some reason:
- Delete the whole file with the following command
rm /var/lib/bitninja/blue.pid -y
- And then restart BitNinja with the
service bitninja restartcommand
