Kako konfigurirati Monit proces na Vesta CP panelu CentOS 7 sistema?

Ranije je Chen Weiliang na svom blogu podijelio tutorijal o instaliranju i konfigurisanju Monita na CentOS 6. ▼

🔗Kako koristiti Monit monitoring na CentOS 6? Uputstvo za instalaciju i deinstalaciju Linuxa Monit

Međutim, konfigurisanje programa za praćenje Monit u CentOS-u 7 donekle se razlikuje od onog u CentOS-u 6; nije u potpunosti isto.

🔗Kako instalirati program za praćenje Monit na VestaCP panel sistema CentOS 7?

Ako vaš Linux host koristi CentOS 7 i ako ste instalirali Monit u Vesta CP panelu, možete slijediti ovaj vodič za konfiguraciju Monit programa za praćenje.

Usluga praćenja procesa praćenja

Slijedi sadržaj konfiguracije usluge u procesu praćenja Monit (izbrišite neke manje korištene usluge nadzora):

Pratite konfiguraciju nadzora

Nazivi Monit konfiguracijskih datoteka razlikuju se za CentOS 6 i 7:

• Ime Monit konfiguracijske datoteke za CentOS 6 je "monit.conf"
• Ime Monit konfiguracijske datoteke za CentOS 7 je "monitrc"

Nakon što pristupite svom Linux serveru pomoću SFTP softvera , uredite konfiguracijsku datoteku Monit-a ▼

/etc/monitrc

Dodajte sljedeći konfiguracijski sadržaj ovoj "monitrc" datoteci ▼

## Monit control file
################################################## #############################
#
# 检查周期，默认为2分钟，对于网站来说有点长，可以根据需要自行调节，这改成30秒。
set daemon 30

include /etc/monit.d/*

# 日志文件
set logfile /var/log/monit.log

#
# 邮件通知服务器
#
#set mailserver mail.example.com
set mailserver localhost with timeout 30 seconds

#
# 通知邮件的格式设置，下面是默认格式供参考
#
## Monit by default uses the following alert mail format:
##
## --8<--
## From: monit@$HOST # sender
## Subject: monit alert -- $EVENT $SERVICE # subject
##
## $EVENT Service $SERVICE #
## #
## Date: $DATE #
## Action: $ACTION #
## Host: $HOST # body
## Description: $DESCRIPTION #
## #
## Your faithful employee, #
## monit #
## --8<--
##
## You can override the alert message format or its parts such as subject
## or sender using the MAIL-FORMAT statement. Macros such as $DATE, etc.
## are expanded on runtime. For example to override the sender:
#
# 简单的，这只改了一下发送人，有需要可以自己修改其它内容。
set mail-format { from: admin@xxxx }

# 设置邮件通知接收者。建议发到gmail，方便邮件过滤。
set alert xxx@xxxx

set httpd port 2812 and #设置http监控页面的端口
use address www.etufo.org # http监控页面的IP或域名
##allow localhost # 允许本地访问
##allow 203.82.90.239 # 允许指定IP访问
allow user:password # 访问用户名密码

Ako ste izmijenili sadržaj konfiguracije MONIT-a, morate ponovo pokrenuti Monit servis da bi stupio na snagu▼

systemctl restart monit

Ažuriranje 2018.:

cd /etc/monit.d/
git clone https://github.com/infinitnet/vesta-centos7-monit.git ./ && rm -f README.md
myip=1.2.3.4
sed -i 's/host localhost/host '$myip'/g' /etc/monit.d/*.conf
systemctl restart monit

• Zamijenite svojim zajedničkim IP-om1.2.3.4.

Nije moguće pronaći git bash komandu jer može doći do greške ▼

🔗CentOS 7 greška git bash komanda nije pronađena linux

Takođe se može pojaviti da nakon unosa ove komande ▼

sed -i 's/host localhost/host '$myip'/g' /etc/monit.d/*.conf

Pojavljuje se sljedeća poruka o grešci ▼

sed: can't read /etc/monit.d/*.conf: No such file or directory

Greška pregleda dnevnika praćenja

SSH naredba monit.log log fajla▼

tailf /var/log/monit.log

• SSH za pregled datoteke monit.log, može se prikazati samo zadnjih 10 redova dnevnika.

Preporučuje se SFTP prijava /var/log/monit.log da biste u potpunosti vidjeli status prethodne datoteke dnevnika monit.log.

Greška pri slanju e-pošte

Ako se Monit mail ne može poslati, pojavit će se sljedeća poruka o grešci ▼

error : Cannot open a connection to the mailserver localhost:25 -- Operation now in progress
error : Mail: Delivery failed -- no mail server is available

Ispravite greške pri slanju e-pošte

Chen Weiliang preporučuje korištenje Gmail SMTP-a ▼

set mailserver smtp.gmail.com port 587
username "[email protected]"
password "password"
using tlsv1
with timeout 30 seconds

Rješenje je zamijeniti postavljeni mail server u Monit konfiguracijskoj datoteci, molimo pogledajte ovaj vodič za detalje ▼

🔗Monit log prompt Mail: 534 5.7.14 https://support.google.com/mail/answer/78754 – gsmtp

statistička greška sistema datoteka

Ako pronađete sljedeće greške u datoteci dnevnika monit.log ▼

filesystem statistic error: cannot read /proc/diskstats -- No such file or directory

• Vjerojatno zato što je Linux zadana minimalna instalacija VestaCPpanel, ne postoji /proc/diskstats Datoteka za praćenje statusa diska.

riješiti statističke greške sistema datoteka

korak 1:SSH in /etc/monit.d katalog ▼

cd /etc/monit.d

Korak 2: Izbrišite datoteku Monit servisa za praćenje "root-space.conf" ▼

rm -rf root-space.conf

Korak 3: Ponovo pokrenite Monit nadzor putem SSH-a ▼

systemctl restart monit.service

Monit naredba (posebna za CentOS 7)

Pogledajte status pokretanja Monita ▼

systemctl status monit.service

Pokrenite uslugu Monit ▼

systemctl start monit.service

Zatvorite uslugu Monit▼

systemctl stop monit.service

Ponovo pokrenite Monit uslugu ▼

systemctl restart monit

Pokrenite uslugu Monit pri pokretanju ▼

systemctl enable monit.service

Uključite i isključite uslugu Monit ▼

systemctl disable monit.service
