Ki jan yo enstale lojisyèl siveyans Monit sou CentOS Webpanel (CWP7)?

Nan leson patikilye sa a nou pral montre w koumanCentOS CentOS Webpanel (CWP7) enstalasyon sou 7Monit siveyans.

Ki sa ki Monit siveyans?

Monit siveyans se yon sous gratis epi ouvè软件, li se yon trè itilLinuxpwogram siveyans.

• Li ka otomatikman kontwole ak jere pwosesis sèvè, fichye, anyè, pèmisyon checksum, sistèm dosye ak sèvis nan UNIX/Linux.
• Pou egzanp: Apache, Nginx,Miskl, FTP, SSH, Postfix, elatriye...
• Jesyon sistèm ki baze sou sistèm ki bay ekselan kapasite siveyans pou administratè sistèm yo.

Poukisa enstale Monit siveyans?

Ou ka itilize siveyans Monit pou diminye tan an, wiE-commerceSit wèbSEO和Maketing Entènètse yon efè oksilyè.

Paske lè nenpòt sèvis ki desann, Monit tcheke li epi li kòmanse sèvis la otomatikman.

Pou egzanp: si sèvis Apache oswa Nginx ou a desann san okenn rezon, Lè sa a, monit pral tcheke, epi si li jwenn yo dwe desann, Lè sa a, monit pral otomatikman kòmanse sèvis ki gen rapò yo.

Yon bagay enteresan se ke monit kouri pwòp sèvis httpd li yo.

Si sèvis apache ou a desann, monit ap kouri ak pwòp sèvis li.

Ki jan yo enstale ak enstale lojisyèl siveyans Monit nan CWP 7?

Pou w konplete leson patikilye sa a, w ap bezwen kondisyon sa yo:

1.  CentOS Linux vèsyon 7 (nwayo)
2.  CWP7
3.  CSF Firewall

Etap 1: SSHMete ajou depo YUM ou a, epi enstale Monit monitoring▼

yum update -y
yum install monit

Etap 2:Louvri pò 2812 sou firewall CSF ▼

vi /etc/csf/csf.conf
# Allow incoming TCP ports
 TCP_IN = "20,21,22,2812,25,53,80,110,143,443,465,587,993,995,2030,2031,2082,2083,2086,2087,2095,2096" 

Etap 3: Rekòmanse CSF Firewall▼

csf -r 

Etap 4:ak SFTP软件Apre w fin antre nan sèvè Linux la, edite fichye konfigirasyon Monit la/etc/monitrc▼

set daemon  30              # check services at 30 seconds intervals
set log syslog
set pidfile /var/run/monit.pid
set idfile  /var/.monit.id
set statefile /var/.monit.state
include /etc/monit.d/*
set mailserver localhost port 25
set eventqueue
basedir /var/monit  # set the base directory where events will be stored
slots 100           # optionally limit the queue size
set alert admin@xxxxx #receive all alerts
set alert admin@xxxxx not on { instance, action } 
set httpd port 2812 and use address 0.0.0.0 
allow 0.0.0.0/0.0.0.0 
allow admin:monit # require user 'admin' with password 'monit'

Etap 5:Tcheke sentaks Monit pou erè ▼

# monit -t
Control file syntax OK  

Si w manke, kreye dosye sa yo:

# touch /var/run/monit.pid 
# touch /var/log/moinit.log

Monit ajoute sèvis siveyans

Koulye a, nou pral kontwole kèk sèvis tankouamavisd, clamd, crond, php-fpm ak cwpsrv.Louvri fichye konfigirasyon monit la/etc/monitrc, epi ajoute kòd sa a nan fen liy lan:

Siveye CWP.amavisd 

# vi /etc/monitrc 
check process amavisd with pidfile /var/run/amavisd/amavisd.pid
        start program "/usr/bin/systemctl start amavisd.service"
        stop program "/usr/bin/systemctl stop amavisd.service"
        if failed unixsocket /var/run/amavisd/amavisd.sock then restart
        if cpu > 70% for 4 cycles then alert
        if cpu > 90% for 8 cycles then restart
        if 4 restarts within 8 cycles then timeout

Siveye CWP.clamd

# vi /etc/monitrc 

check process clamd with pidfile /var/run/clamd.amavisd/clamd.pid
        start program "/usr/bin/systemctl start clamd.service"
        stop program "/usr/bin/systemctl stop clamd.service"
        if failed unixsocket /var/run/clamd.amavisd/clamd.sock then restart
        if cpu > 70% for 4 cycles then alert
        if cpu > 90% for 8 cycles then restart
        if 4 restarts within 8 cycles then timeout 

Siveye CWP.crond

# vi /etc/monitrc 

check process crond with pidfile /var/run/crond.pid
        start program = "/usr/bin/systemctl start crond.service"
        stop  program = "/usr/bin/systemctl stop crond.service" 

Siveye CWP.cwp-phpfpm

# vi /etc/monitrc

check process cwp-phpfpm matching "cwp-phpfpm"
        start program "/usr/bin/systemctl start cwp-phpfpm.service"
        stop program "/usr/bin/systemctl stop cwp-phpfpm.service"
        if failed unixsocket /usr/local/cwp/php71/var/sockets/cwpsrv.sock then restart
        if failed unixsocket /usr/local/cwp/php71/var/sockets/cwpsvc.sock then restart
        if failed unixsocket /usr/local/cwp/php71/var/sockets/login.sock then restart
        if cpu > 70% for 4 cycles then alert
        if cpu > 90% for 8 cycles then restart
        if 4 restarts within 8 cycles then timeout 

kontwole cwp.cwpsrv

# vi /etc/monitrc

check process cwpsrv with pidfile /usr/local/cwpsrv/var/run/nginx.pid
        start program "/usr/bin/systemctl start cwpsrv.service"
        stop program "/usr/bin/systemctl stop cwpsrv.service"
        if 4 restarts within 8 cycles then timeout 

Yon fwa konfigirasyon, monit ta dwe rechaje epi reli fichye konfigirasyon an, epi koòdone entènèt la ap disponib:

monit reload

Ki kote dosye pidfile pwosesis baz done MySQL la?Rechèch lòd MySQL pidfile

Paske pwosesis MySQL nan sistèm Linux la pral desann, men enstale ak konfigirasyon pwogram siveyans MONIT la, ou bezwen rele dosye a pidfile nan pwosesis sistèm MySQL la, men ou pa konnen ki kote yo jwenn dosye a pidfile, ale pou kont li. ki jan yo jwenn dosye a pidfile MySQL ... ...

1) Telechaje dosye sèvis siveyans Monit ▼

• Nan paj telechaje a, klike sou bouton "Telechaje kounye a" nan telechaje nòmal la pou telechaje dosye sèvis siveyans Monit pou gratis.
• (Kod aksè: 5588)

2) Dekonprime ak telechaje nan /etc/monit.d/ anyè.

• si nanMonit fichye konfigirasyon Gen yon sèvis siveyans ak menm konfigirasyon an nan /etc/monitrc, ki bezwen yo dwe在Monit fichye konfigirasyon /etc/monitrc efase, sinon yon erè ap fèt.

Apre ou fin kreye dosye konfigirasyon ki nesesè yo, teste pou erè sentaks▼

Si èd memwa sa a parèt ▼

monit -t

Si pa gen okenn erè, aktive epi rekòmanse sèvis monitè a ▼

systemctl enable monit
systemctl restart monit

Kòmanse sèvis Monit nan bòt ▼

systemctl enable monit.service

Koulye a tcheke jounal siveyans ▼

Kòmanse monitè ak kòmandman an ▼

monit

Tcheke sitiyasyon Monit ▼

monit status

Rechaje li pou chanjman yo pran efè▼

monit reload

Kòmanse kouri tout pwogram ki kontwole pa Monit▼

monit start all

Rekòmanse tout sèvis siveyans lè Monit▼

monit restart all

Pou kòmanse, sispann ak rekòmanse sèvis espesifik, ou ka itilizemonit start nameTankou yon lòd ▼

monit start httpd
monit stop sshd 
monit restart nginx

Rezime Siveyans Monit▼

monit summary

Kounye a, konekte sou sèvè monit la lè l sèvi avèk non itilizatè ak modpas Monit ou te fikse anvan an.

URL konekte:http://SERVER_FQDN:2812

Rezoud pwoblèm nan ke sèvis Monit toujou pa siveye

Monit gen ladan kòmandman pou pèmèt ak enfim siveyans tout oswa sèvis espesifik.

Si sèvis Monit la toujou pa siveye, ou ka itilize lòd sa a▼

monit monitor mysql

Oswa re-aktive tout siveyans ▼

monit monitor all

• Remake byen ke ou dwe aktive koòdone Monit HTTP pou kòmandman sa yo travay.

Monit Command (espesyal pou CentOS 7)

Gade sitiyasyon demaraj Monit▼

systemctl status monit.service

Kòmanse sèvis Monit la ▼

systemctl start monit.service

Fèmen sèvis Monit ▼

systemctl stop monit.service

Rekòmanse sèvis Monit la▼

systemctl restart monit

Kòmanse sèvis Monit nan bòt ▼

Monit Nòt

Monit kontwole sèvis pwosesis, ki vle di ke sèvis kontwole pa Monit pa ka sispann lè l sèvi avèk metòd nòmal, paske yon fwa sispann, Monit pral rekòmanse yo.

Pou sispann yon sèvis ki kontwole pa Monit, ou ta dwe itilize yon bagay tankoumonit stop nameTankou yon lòd, pou egzanp yo sispann nginx ▼

monit stop nginx

Pou sispann tout sèvis Monit kontwole, antre lòd sa a▼

monit stop all

Dezenstale pwogram siveyans Monit ▼

yum remove monit
