Kepiye carane nginstal piranti lunak pemantauan Monit ing CentOS Webpanel (CWP7)?

Ing tutorial iki kita bakal nuduhake sampeyan caraneCentOS Instalasi CentOS Webpanel (CWP7) ing 7Monitoring.

Apa Monitoring Monit?

Pemantauan Monit minangka sumber gratis lan mbukak软件, iku banget migunaniLinuxprogram monitoring.

• Bisa ngawasi lan ngatur proses server, file, direktori, ijin checksum, sistem file lan layanan kanthi otomatis ing UNIX/Linux.
• Contone: Apache, Nginx,MySQL, FTP, SSH, Postfix, lsp...
• Manajemen sistem basis sistem sing nyedhiyakake kemampuan ngawasi sing apik kanggo administrator sistem.

Napa nginstal pemantauan Monit?

Sampeyan bisa nggunakake pemantauan Monit kanggo nyuda downtime, yaE-commerceSitus webSEO和Internet Marketingminangka efek tambahan.

Amarga nalika ana layanan mudhun, Monit mriksa lan miwiti layanan kanthi otomatis.

Contone: yen layanan Apache utawa Nginx sampeyan mudhun tanpa alesan, banjur monit bakal mriksa, lan yen ditemokake mudhun, banjur monit bakal kanthi otomatis miwiti layanan sing gegandhengan.

Siji bab sing menarik yaiku monit nganggo layanan httpd dhewe.

Yen layanan apache sampeyan mudhun, monit bakal mbukak nganggo layanan dhewe.

Kepiye carane nginstal lan nginstal piranti lunak pemantauan Monit ing CWP 7?

Kanggo ngrampungake tutorial iki, sampeyan butuh prasyarat ing ngisor iki:

1.  CentOS Linux versi 7 (inti)
2.  CWP7
3.  CSF Firewall

Langkah 1: SSHNganyari repositori YUM sampeyan, banjur instal pemantauan Monit▼

yum update -y
yum install monit

Langkah 2:Bukak port 2812 ing 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" 

Langkah 3: Wiwiti maneh CSF Firewall▼

csf -r 

Langkah 4:karo SFTP软件Sawise ngetik server Linux, sunting file konfigurasi Monit/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'

Langkah 5:Priksa sintaks Monit kanggo kesalahan ▼

# monit -t
Control file syntax OK  

Yen ora ana, gawe file ing ngisor iki:

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

Yen Redis wis diinstal, sampeyan bisa uga kudu ngatur kanthi manual alamat lokasi file pid Redis ▼

Monit nambah layanan ngawasi

Saiki, kita bakal ngawasi sawetara layanan kayataamavisd, clamd, crond, php-fpm lan cwpsrv.Bukak file konfigurasi monit/etc/monitrc, lan tambahake kode ing ngisor iki ing pungkasan baris:

Monitor 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

Ngawasi 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 

Monitor 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" 

Ngawasi 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 

ngawasi 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 

Sawise dikonfigurasi, monit kudu mbukak maneh lan maca maneh file konfigurasi, lan antarmuka web bakal kasedhiya:

monit reload

查询database MySQLKanggo cara proses pidfile, priksa tutorial ing ngisor iki ▼

• yen ingMonit file konfigurasi Ana layanan ngawasi kanthi konfigurasi sing padha ing /etc/monitrc, sing kudu ana在Monit file konfigurasi /etc/monitrc wis dibusak, yen ora bakal ana kesalahan.

Sawise nggawe file konfigurasi sing dibutuhake, nyoba kanggo kesalahan sintaks▼

monit -t

Yen pituduh ing ngisor iki katon ▼

monit -t
/etc/monit.d/cwp.mariadbd:1: Service name conflict, mysql already defined '"/usr/sbin/mariadbd"'

• Iki tegese /etc/monit.d/cwp.mariadbd:1: Konflik jeneng layanan; mysql wis ditetepake '"/usr/sbin/mariadbd"'
• punika katranganipuncwp.mariadbdFile wis ana, mung mbusakcwp.mysqldberkas.

Yen ora ana kesalahan, aktifake lan miwiti maneh layanan monit ▼

systemctl enable monit
