🔗Hoe kinne jo Monit-monitoring brûke op CentOS 6? Linux ynstallaasje en de-ynstallaasje Monit tutorial

Lykwols, yn CentOS 7 konfiguraasjeMonit tafersjochIt programma, mei wat ferskillen fan CentOS 6, is net krekt itselde.

🔗Hoe kinne jo it Monit-monitoringsprogramma ynstallearje op it VestaCP-paniel fan CentOS 7-systeem?

as dynlinuxDe host brûkt it CentOS 7-systeem. Nei it ynstallearjen fan Monit op it Vesta CP-paniel kinne jo dizze tutorial folgje om it Monit-monitoringsprogramma te konfigurearjen.

Monit tafersjoch proses tsjinst

It folgjende is de tsjinstkonfiguraasjeynhâld fan it Monit-monitoringsproses (wiskje wat minder brûkte tafersjochtsjinsten):

Monit monitoring konfiguraasje

De Monit-konfiguraasjetriemnammen binne oars foar CentOS 6 & 7:

• De namme fan it Monit-konfiguraasjetriem foar CentOS 6 is "monit.conf"
• De namme fan it Monit-konfiguraasjetriem foar CentOS 7 is "monitrc"

mei SFTP SoftwareNei it ynfieren fan jo Linux-tsjinner, bewurkje it Monit-konfiguraasjetriem ▼

/etc/monitrc

# 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

#
# 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

As jo ​​de MONIT-konfiguraasje-ynhâld wizige hawwe, moatte jo de Monit-tsjinst opnij starte om effekt te hawwen▼

systemctl restart monit

Update 2018 mei 5:

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

• Ferfange mei jo dielde IP1.2.3.4.

Koe it kommando git bash net fine, om't der in flater kin foarkomme ▼

🔗CentOS 7 flater: git bash kommando net fûn linux

It kin ek ferskine dat nei it ynfieren fan dit kommando ▼

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

It folgjende flaterberjocht ferskynt ▼

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

SSH besjen monit.log log triem kommando▼

tailf /var/log/monit.log

• SSH om it monit.log-bestân te besjen, kinne allinich de lêste 10 rigels fan logs werjûn wurde.

SFTP-oanmelding wurdt oanrikkemandearre /var/log/monit.log om de status fan it foarige monit.log-lochbestân folslein te besjen.

Email ferstjoeren flater

As de Monit-post net ferstjoerd wurde kin, sil it folgjende flaterberjocht ferskine ▼

De oplossing is om de ynstelde mailserver te ferfangen yn it Monit-konfiguraasjetriem, sjoch asjebleaft dit tutorial foar details ▼
