Systemctl daemon-reload est-il le même service de redémarrage de systemctl?
J'ai un nom de service serviceA dans ubuntu16 et, en même temps, c'est un démon.
Donc, quand je fais systemctl daemon-reload, cela inclut-il l'action de systemctl restart serviceA?
Non
De man systemctl (peut-être la plus longue page de manuel au monde):
Manager Lifecycle Commands
daemon-reload
Reload the systemd manager configuration. This will rerun all generators (see
systemd.generator(7)), reload all unit files, and recreate the entire
dependency tree. While the daemon is being reloaded, all sockets systemd
listens on behalf of user configuration will stay accessible.
This command should not be confused with the reload command.
Il existe une distinction entre reload et restart
Unit Commands
reload PATTERN...
Asks all units listed on the command line to reload their configuration. Note
that this will reload the service-specific configuration, not the unit
configuration file of systemd. If you want systemd to reload the configuration
file of a unit, use the daemon-reload command. In other words: for the example
case of Apache, this will reload Apache's httpd.conf in the web server, not
the Apache.service systemd unit file.
This command should not be confused with the daemon-reload command.
restart PATTERN...
Restart one or more units specified on the command line. If the units are not
running yet, they will be started.
