Monit kann MySQL nicht erkennen

Monit kann MySQL nicht erkennen

Die Monit-Weboberfläche zeigt: Ausführung fehlgeschlagen | Existiert nicht

netstat gibt mir:

sudo netstat -lnp | grep mysql

Selbst wenn MySQL läuft und aktiv ist, kann Monit es nicht erkennen. Ich habe den symbolischen Link wie folgt gesetzt:

sudo ln -s /etc/monit/conf-available/mysql /etc/monit/conf-enabled/

TylerAntworten aufeine andere Fragedarüber:

Unter Ubuntu 20.04 LTS habe ich festgestellt, dass die PID-Datei und der Socket in auskommentiert waren /etc/mysql/mysql.conf.d/mysqld.cnf. Ich habe diese beiden Zeilen auskommentiert, dann mysql mit service mysql restartund monit mit neu gestartet service monit restartund monit konnte den mysqld-Prozess erfolgreich überwachen.

Bei mir hat es übrigens funktioniert. Danke @Tyler (ich kann dort nicht hochstimmen und kommentieren)
