None of these worked for me. I had to delete the $AIRFLOW_HOME/airflow-webserver.pid file and then running airflow webserver worked.

Create a init script and use the command "daemon" to run this as service.

daemon --user="${USER}" --pidfile="${PID_FILE}" airflow webserver -p 8090 >> "${LOG_FILE}" 2>&1 &
