Kumaha carana masang sareng masang parangkat lunak monitoring Monit di CWP 7?

Pikeun ngalengkepan tutorial ieu, anjeun peryogi prasyarat ieu:

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

Lengkah 1: SSHApdet gudang YUM anjeun, teras pasang Monit monitoring▼

yum update -y
yum install monit

第 2:Buka port 2812 dina 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" 

Lengkah 3: Balikan deui CSF Firewall▼

csf -r 

第 4:kalawan SFTP软件Sanggeus asup kana server Linux, edit file konfigurasi Monit/etc/monitrc▼

set daemon  30              # check services at 30 seconds intervals
set log syslog
set pidfile /var/run/monit.pid
