Directions of service for continuos working
|
||||
|
||||
Command for the terminal to move the file to a more safe direction, where
|
||||
"executable" is the name of the of the program executable in the folder
|
||||
and "(/usr/ocal/bin/executable)" this are the new direction for the program
|
||||
|
||||
"sudo mv executable /usr/local/bin/executable"
|
||||
|
||||
After that we create the file of "systemd" with the next Command
|
||||
|
||||
"sudo nano /etc/systemd/system/sensor.service"
|
||||
|
||||
Now inside these file we put the next code:
|
||||
|
||||
[Unit]
|
||||
Description=Servicio de lectura de sensores HTU21D y BH1750
|
||||
After=network.target
|
||||
|
||||
[Service]
|
||||
ExecStart=/usr/local/bin/sensor_logger -> changer sensor_logger to the name of the exutable file.
|
||||
Restart=always
|
||||
User=debian
|
||||
WorkingDirectory=/home/debian
|
||||
StandardOutput=file:/home/debian/sensor.log
|
||||
StandardError=file:/home/debian/sensor_error.log
|
||||
|
||||
[Install]
|
||||
WantedBy=multi-user.target
|
||||
|
||||
after that we allow the service with the next commands
|
||||
|
||||
sudo systemctl daemon-reexec
|
||||
sudo systemctl daemon-reload
|
||||
sudo systemctl enable sensor.service
|
||||
sudo systemctl start sensor.service
|
||||
|
||||
At the end we check the status of the service with the next commands
|
||||
|
||||
sudo systemctl status sensor.service
|
||||
|
||||
To eliminate the service we need to enter the next commands
|
||||
|
||||
sudo systemctl stop sensor.service
|
||||
sudo systemctl disable sensor.service
|
||||
sudo rm /etc/systemd/system/sensor.service
|
||||
sudo systemctl daemon-reload
|
||||
|
||||
in the case in which create files to see the logs enter the next commands
|
||||
to eliminate the logs.
|
||||
|
||||
rm /home/debian/sensor.log
|
||||
rm /home/debian/sensor_error.log
|
||||
|
||||
La dirección puede variaar dependiendo de la cual se haya puesto al principio
|
||||
de desarrollo.
