Ta yaya CentOS 6 ke amfani da Monit don saka idanu? Shigar Linux da cirewa na koyawa Monit

CentOS 6 Yadda ake amfani da shisaka idanu?

LinuxShigar kuma cire koyawa monit

Shirin saka idanu na monit kayan aiki ne na buɗe tushen sa ido na tsarin aiki na Linux.Yana iya taimaka maka amfani da mai binciken gidan yanar gizo don lura da tsarin tsarin.Lokacin da shirin ko sabis ya gaza, monit na iya sake kunna shi ta atomatik.

ana iya sarrafa monit kai tsaye akan layin umarni, zaku iya sanya ayyuka masu yawa (ba sa ido kawai ba), don haka idan wani sabis ɗin ya gaza cak ɗin, zaku iya wuce faɗakarwar monit ko yin wani abu ( gwada sake kunna wasu ayyuka).

Wannan labarin yana ɗauka cewa kun san aƙalla mahimman abubuwan Linux, san yadda ake amfani da SSH, kuma mafi mahimmanci, ku ɗauki bakuncin rukunin yanar gizon ku akan VPS na ku.

Shigar da shirin saka idanu na Monit a zahiri abu ne mai sauqi qwarai, zan nuna muku mataki-mataki shigarwa na monit akan CentOS 6.

Mataki 1: Kunna ma'ajiyar EPEL

RHEL/CentOS 7 64-bit:

wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -ivh epel-release-latest-7.noarch.rpm

RHEL/CentOS 6 32-bit:

wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
 rpm -ivh epel-release-6-8.noarch.rpm

• CentOS 7 baya goyan bayan ma'ajiyar EPEL 32-bit, don haka yi amfani da, RHEL/CentOS 6 32-bit.

Mataki 2: Shigar monit

yum update
yum install -y libcrypto.so.6 libssl.so.6
yum install monit

Mataki na 3: Sanya monit

Da zarar an shigar, gyara babban fayil ɗin sanyi kuma saita sunan mai amfani da kalmar wucewa, duba misalin da ke ƙasa:

nano /etc/monit.conf

Shirya fayil ɗin daidaitawar monit:

 set httpd port 2812 and  # # set the listening port to your desire.
 use address localhost    # only accept connection from localhost
 allow localhost          # allow localhost to connect to the server and
 allow admin:monit        # require user 'admin' with password 'monit'
 allow @monit             # allow users of group 'monit' to connect (rw)
 allow @users readonly # allow users of group 'users' to connect readonly

Don cikakkun bayanai kan yadda ake saita monit, da fatan za a bincika wannan "Yadda ake saita fayil monit.conf? monit sanyi fayil kwatancin misali"labarin.

Da zarar kun canza sabon saitin, kuna buƙatar kunna saitunan sake kunnawa na sabis ɗin monit:

duba daidaitaccen farawa, tsayawa, sake kunna umarni:

/etc/init.d/monit restart

Mataki na 4: Sanya sabis na saka idanu

Bayan an gama saitin farko, za mu iya saita wasu ayyuka waɗanda muke son saka idanu.

Anan akwai wasu misalan daidaitawa masu amfani don monit:
