=Useful Debian systemd commands= ===Apache=== a2ensite (config file) a2dissite (config file) ... and then systemctl reload apache2 systemctl [start|stop] apache2 systemctl status systemctl status apache2 ===failed services=== See them with systemctl list-units --state=failed error messages with journalctl -u servicename.service systemctl edit apache2 # will edit the override file with nano systemctl restart postgrey 2022-02-21 it was reporting "notify-email@apache2.service" was down. clear it with systemctl reset-failed notify-email@apache2.service 2025-07-23 installed apparmor and bind9 wouldn't start. Had to edit /etc/apparmor.d/usr.sbin.named to change the /var/log/named/ directory line to just the file, restart apparmor, double check that /var/log/named was bind:bind and 644, and restart bind9 See the journal journalctl -u mariadb journalctl -u apache2 journalctl -f # follow journalctl -f -u apache2.service # follow, only that service ==bind / dns== Zone files are in /var/named/ Conf file is in /etc/bind/named.conf.local systemctl reload bind9
