Tuhinga o muaKo Chen WeiliangKua tirihia te BlogCentOS 6 Akoranga ki te whakauru me te whirihora a Monit ▼
Heoi, i roto i te whirihoranga CentOS 7Te aro turukiKo te kaupapa, me etahi rereke mai i te CentOS 6, kaore i te rite.
mena ko toLinuxKa whakamahia e te kaihautu te punaha CentOS 7. I muri i te whakauru i te Monit ki te paewhiri Vesta CP, ka taea e koe te whai i tenei akoranga ki te whirihora i te kaupapa aroturuki Monit.
Monit ratonga tukanga aroturuki
E whai ake nei te ihirangi whirihoranga ratonga o te tukanga aroturuki a Monit (muku etahi ratonga aroturuki kua iti ake te whakamahi):
-
papaki - cron
- whare kukupa
- Tuhinga
- httpd
-
memcached - mysql
- nginx
-
kaikohuru - sshd
- vesta-nginx
- vesta-php
- Tuhinga o mua
-
Aroturuki mokowā me ngā inodes i runga -
Aroturuki i nga rauemi punaha (RAM, whakawhiti, PTM, uta)
whirihoranga aroturuki Monit
He rereke nga ingoa konae whirihoranga Monit mo CentOS 6 & 7:
- Ko te ingoa o te konae whirihoranga Monit mo CentOS 6 ko "monit.conf"
- Ko te ingoa o te konae whirihoranga Monit mo CentOS 7 ko "monitrc"
me te SFTP 软件Whai muri i to urunga ki to tūmau Linux, whakatikahia te konae whirihoranga Monit ▼
/etc/monitrc
Tāpirihia ngā ihirangi whirihoranga e whai ake nei ki tēnei kōnae "monitrc" ▼

Mena kua whakarereketia e koe te ihirangi whirihoranga MONIT, me whakaara ano te ratonga Monit kia whai mana▼
systemctl restart monit
Whakahoutanga i te Pipiri 2018, 5:
- E taunaki ana kia whakamahia te ihirangi whirihoranga o runga ake nei ▲
- Ko nga whakahau SSH e whai ake nei kaore i te tūtohutia ki te whakaputa i nga konae mo te ratonga aroturuki Monit.
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 '$myip'/g' /etc/monit.d/*.conf
systemctl restart monit
- Whakakapihia me to IP tiritahi1.2.3.4.
Kaore i kitea te tono git bash na te mea ka puta he hapa ▼
Ka puta ano pea i muri i te whakauru i tenei whakahau ▼
sed -i 's/host localhost/host '$myip'/g' /etc/monit.d/*.conf
Ka puta te karere hapa e whai ake nei ▼
sed: can't read /etc/monit.d/*.conf: No such file or directory
Hapa tirohanga rangitaki Monit
Tiro SSH monit.log tono kōnae rangitaki▼
tailf /var/log/monit.log
- SSH ki te tiro i te konae monit.log, ko nga rarangi 10 whakamutunga anake ka taea te whakaatu.
E taunaki ana te takiuru SFTP /var/log/monit.log
ki te tino tiro i te mana o te konae rangitaki monit.log o mua.
Hapa tuku imeera
Ki te kore e taea te tuku mēra Monit, ka puta te karere hapa e whai ake nei ▼
error : Cannot open a connection to the mailserver localhost:25 -- Operation now in progress error : Mail: Delivery failed -- no mail server is available
Whakatikahia nga hapa tuku imeera
Ko Chen WeiliangE taunaki ana kia whakamahiaGmail SMTP ▼
set mailserver smtp.gmail.com port 587 username "[email protected]" password "password" using tlsv1 with timeout 30 seconds
Ko te otinga ko te whakakapi i te tuumau mēra kua whakaritea i roto i te konae whirihoranga Monit, tirohia tenei akoranga mo nga taipitopito ▼
hapa tatauranga pūnaha kōnae
Mena ka kitea e koe nga hapa e whai ake nei i roto i te konae rangitaki monit.log ▼
filesystem statistic error: cannot read /proc/diskstats -- No such file or directory
- Ko te mea pea na te mea ka taka te Linux ki te whakaurunga iti VestaCPröpü, karekau
/proc/diskstats
Kōnae aroturuki tūnga kōpae.
whakatau i nga hapa tatauranga o te punaha konae
taahiraa 1:SSH roto /etc/monit.d
rārangi ▼
cd /etc/monit.d
taahiraa 2:Mukua te kōnae ratonga aroturuki Monit "root-space.conf" ▼
rm -rf root-space.conf
taahiraa 3:Ka timata ano a SSH i te aroturuki a Monit ▼
systemctl restart monit.service
Monit Command (Motuhake mo CentOS 7)
Tirohia te mana whakaoho o Monit ▼
systemctl status monit.service
Tīmatahia te ratonga Monit ▼
systemctl start monit.service
Katia te ratonga Monit▼
systemctl stop monit.service
Tīmataria anō te ratonga Monit ▼
systemctl restart monit
Tīmatahia te ratonga Monit i te boot ▼
systemctl enable monit.service
Whakakā, whakawetohia te ratonga Monit ▼
systemctl disable monit.service
