Quiero depurar / probar un programa en eclipse que usa un servidor Redis, así que decidí convertir el servidor en un servicio de usuario para tener el privilegio de ejecutarlo. Lo que me molesta es que puedo iniciar o detener el servicio pero no activarlo / desactivarlo.
El error que obtengo es:
Failed to execute operation: No such file or directory

systemctl daemon-reload
después de mover / editar los archivos?Respuestas:
En mi caso, estaba colocando los archivos de mi unidad systemd directamente debajo de las
/etc/systemd/system/...
carpetas. En su/lib/systemd/system
lugar, los movió y eso resolvió el problema con los comandos systemctl enable / disable.fuente
¿Problema de enlace simbólico?
Recibí un mensaje de error similar al usar enlaces simbólicos.
Aparentemente systemd no sigue enlaces simbólicos, la solución es simplemente copiar o mover el archivo.
Servicio al usuario?
Creo que necesita agregar
--user
a la línea de comando para unidades enuser/
:fuente
start
el servicio, peroenable
no lo hizoTratar:
sudo touch /etc/init.d/arkos-redis
Yo tuve el mismo problema. Si eso no funciona:
sudo strace systemctl enable arkos-redis
Busque dónde ocurre la última falla.
fuente
He tenido el mismo problema en Fedora 29.
Reemplazar:
After=network.target
con:
Requires=network.target
Es increíblemente frustrante porque el archivo está claramente allí, pero nada parece querer verlo. Tampoco hay fallas en el análisis del sistema. Simplemente se muestra como 'malo' debajo
systemctl --list-unit-files

Recibí este error en Redhat cuando el archivo de la unidad estaba vacío
