Mar sin féin, i gcumraíocht CentOS 7Monatóireacht a dhéanamh ar mhonatóireachtNíl an clár, le roinnt difríochtaí ó CentOS 6, díreach mar an gcéanna.
má tá doLinuxÚsáideann an t-óstach córas CentOS 7. Tar éis Monit a shuiteáil ar phainéal Vesta CP, is féidir leat an teagasc seo a leanúint chun an clár monatóireachta Monit a chumrú.
Monatóireacht a dhéanamh ar sheirbhís próisis monatóireachta
Seo a leanas an t-ábhar cumraíochta seirbhíse atá sa phróiseas monatóireachta Monit (scrios roinnt seirbhísí monatóireachta nach n-úsáidtear níos lú):
-
clamd - croinn
- colmán
- exim
- httpd
-
memcached - MySQL
- nginx
-
spamsassin - sshd
- vesta-nginx
- php
- vsftpd

Monatóireacht a dhéanamh ar chumraíocht monatóireachta
Tá na hainmneacha comhaid cumraíochta Monit difriúil do CentOS 6 & 7:
- Is é ainm an chomhaid chumraíochta Monit do CentOS 6 ná "monit.conf"
- Is é ainm an chomhaid chumraíochta Monit do CentOS 7 ná "monitrc"

Má tá an t-ábhar cumraíochta MONIT modhnaithe agat, ní mór duit an tseirbhís Monit a atosú chun go mbeidh éifeacht leis▼
systemctl restart monit
Nuashonrú 2018 Feabhra 5:
- Moltar an t-ábhar cumraíochta thuas a úsáid ▲
- Ní mholtar na horduithe SSH seo a leanas chun comhaid a ghiniúint don tseirbhís monatóireachta 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 '$myip'/g' /etc/monit.d/*.conf
systemctl restart monit
- Ionadaigh le do IP comhroinnte1.2.3.4.
Níorbh fhéidir an t-ordú git bash a aimsiú toisc go bhféadfadh earráid tarlú ▼
D'fhéadfadh sé a bheith le feiceáil freisin tar éis dul isteach an t-ordú seo ▼
sed -i 's/host localhost/host '$myip'/g' /etc/monit.d/*.conf
Tá an teachtaireacht earráide seo a leanas le feiceáil ▼
sed: can't read /etc/monit.d/*.conf: No such file or directory

SSH view monit.log log file command▼
tailf /var/log/monit.log
- SSH chun an comhad monit.log a fheiceáil, ní féidir ach na 10 línte logaí deiridh a thaispeáint.
Moltar logáil isteach SFTP /var/log/monit.log
chun stádas an chomhaid logála monit.log roimhe seo a fheiceáil go hiomlán.
Earráid seolta ríomhphoist
Mura féidir an post Monit a sheoladh, beidh an teachtaireacht earráide seo a leanas le feiceáil ▼
error : Cannot open a connection to the mailserver localhost:25 -- Operation now in progress error : Mail: Delivery failed -- no mail server is available

set mailserver smtp.gmail.com port 587 username "[email protected]" password "password" using tlsv1 with timeout 30 seconds
Is é an réiteach ná an freastalaí ríomhphoist socraithe a athsholáthar sa chomhad cumraíochta Monit, seiceáil an teagasc seo le haghaidh sonraí ▼
earráid staitistic an chórais comhad
Má fhaigheann tú na hearráidí seo a leanas sa chomhad logála monit.log ▼
