Igbese 2: Iṣatunṣe Monit

Monit rọrun pupọ lati tunto, ni otitọ a ṣẹda awọn faili iṣeto lati jẹ kika ni irọrun ni irọrun ati ṣiṣe wọn rọrun fun awọn olumulo lati loye. A ṣe apẹrẹ lati ṣe atẹle awọn iṣẹ ṣiṣe ni gbogbo iṣẹju meji 2 ati tọju awọn akọọlẹ ni “/ var/log/monit“.

Monit ni o ni wiwo wẹẹbu ti o ṣiṣẹ lori ibudo 2812 nipa lilo olupin ayelujara. Lati mu ki oju opo wẹẹbu ṣiṣẹ o nilo lati ṣe awọn ayipada ninu faili iṣeto monit. Faili iṣeto akọkọ ti monit ti o wa ni /etc/monit.conf labẹ (RedHat/CentOS/Fedora) ati/ati be be lo/monit/monitrc faili fun (Ubuntu/Debian/Linux Mint). Ṣii faili yii ni lilo yiyan olootu rẹ.

# vi /etc/monit.conf

Nigbamii ti, ṣe aiṣedeede apakan atẹle naa ki o ṣafikun adirẹsi IP tabi orukọ ìkápá ti olupin rẹ, gba ẹnikẹni laaye lati sopọ ki o yi olumulo monit ati ọrọ igbaniwọle pada tabi o le lo awọn aiyipada.

 set httpd port 2812 and
