Yadda ake Shigar da Sanya Tari tare da Nodes Biyu a cikin Linux - Kashi na 2

Assalamu alaikum. Kafin mu fara kashi na biyu, bari mu sake dubawa game da abin da muka yi a cikin Sashe na 01. A cikin Sashe na 01 na wannan jerin abubuwan tarawa, mun tattauna game da dabarun tarawa da kuma yadda za a iya amfani da shi tare da fa'ida da rashin amfani na tari. Kuma mun rufe abubuwan da aka riga aka tsara don wannan saitin da abin da kowane kunshin zai yi bayan mun daidaita nau'in saitin.

Zaku iya bitar Sashe na 01 da Part 03 daga mahaɗin da ke ƙasa.

  1. Mene ne Tari da Fa'idodi/Rashin Amfanin Tari
  2. Yankewa da Ƙara Mai gazawa zuwa Tari - Kashi na 3

Kamar yadda na fada a labarina na ƙarshe, cewa mun fi son sabobin 3 don wannan saitin; uwar garken ɗaya yana aiki azaman uwar garken tari wasu kuma azaman nodes.

A cikin Sashe na 2 na yau, za mu ga yadda ake girka da kuma daidaita tari akan Linux. Don wannan muna buƙatar shigar da fakitin ƙasa a cikin duka sabobin uku.

Mataki 1: Shigar Clustering a Linux

Don haka bari mu fara shigar da waɗannan fakitin a cikin duk sabobin uku. Kuna iya shigar da duk waɗannan fakiti cikin sauƙi ta amfani da yum package manager.

Zan fara da shigar da kunshin \ricci akan duk waɗannan sabobin guda uku.

# yum install “ricci”

Bayan an gama shigarwar ricci, muna iya ganin ta shigar mod_cluster da cluster lib a matsayin abin dogaro.

Na gaba ina shigar da luci ta amfani da yum install \luci umurnin.

# yum install "luci"

Bayan shigar da luci, zaku iya ganin ta shigar da abubuwan dogaro da yake buƙata.

Yanzu, bari mu shigar da kunshin ccs a cikin sabobin. Don haka na shigar da yum shigar ccs.x86_64 wanda ke nunawa a cikin jerin lokacin da na fitar da yum list |grep \ccs ko kuma kawai za ku iya fitar da yum install \ccs.

# yum install “ccs”

Bari mu shigar da cman a matsayin buƙatun ƙarshe don wannan saitin ta musamman. Umurnin shine yum shigar \cman ko yum shigar cman.x86_64 kamar yadda aka nuna a cikin yum list kamar yadda na ambata a baya.

# yum install “cman”

Muna buƙatar tabbatar da shigarwar suna cikin wurin. Ba da umarni a ƙasa don ganin ko fakitin da muke buƙata an shigar dasu yadda yakamata a cikin duk sabar guda uku.

# rpm -qa | egrep "ricci|luci|modc|cluster|ccs|cman"

Cikakken duk fakitin an shigar da su kuma duk abin da muke buƙatar yi shine saita saitin.

Mataki 2: Sanya Tari a cikin Linux

1. A matsayin mataki na farko don kafa gungu, kuna buƙatar fara sabis na ricci akan duk sabobin uku.

# service ricci start 
OR
# /etc/init.d/ricci start

2. Tun da an fara ricci a duk sabobin, yanzu lokaci ya yi da za a ƙirƙiri gungu. Anan ne fakitin ccs ke zuwa don taimakonmu lokacin daidaita tarin.

Idan baku son amfani da umarnin ccs to dole ne ku gyara fayil ɗin \cluster.conf” don ƙara nodes da yin wasu saitunan. Ina tsammanin hanya mafi sauƙi ita ce amfani da bin umarni. Mu duba.

Tun da ban ƙirƙiri gungu ba tukuna, babu fayil ɗin cluster.conf da aka ƙirƙira a /etc/cluster location tukuna kamar yadda aka nuna a ƙasa.

# cd /etc/cluster
# pwd
# ls

A cikin akwati na, Ina yin wannan a cikin 172.16.1.250 wanda aka keɓe don sarrafa tari. Yanzu gaba, duk lokacin da muka yi ƙoƙarin amfani da uwar garken ricci, zai nemi kalmar sirri ta ricci. Don haka dole ne ku saita kalmar sirri ta mai amfani da ricci a cikin duk sabar.

Shigar da kalmomin shiga don mai amfani da ricci.

# passwd ricci

Yanzu shigar da umarni kamar yadda aka nuna a ƙasa.

# ccs -h 172.16.1.250 --createcluster tecmint_cluster

Kuna iya gani bayan shigar da umarni na sama, an ƙirƙiri fayil ɗin cluster.conf a cikin /etc/cluster directory.

Wannan shine yadda tsoho na cluster.conf yayi kama da kafin in yi saiti.

3. Yanzu bari mu ƙara nodes biyu zuwa tsarin. A nan kuma muna amfani da umarnin ccs don yin daidaitawa. Ba zan gyara fayil ɗin cluster.conf da hannu ba amma yi amfani da tsarin haɗin gwiwa.

# ccs -h 172.16.1.250 --addnode 172.16.1.222

Ƙara sauran kumburin kuma.

# ccs -h 172.16.1.250 --addnode 172.16.1.223

Wannan shine yadda fayil ɗin cluster.conf yayi kama da ƙara sabar node.

Hakanan zaka iya shigar da umarni na ƙasa don tabbatar da bayanan kumburi.

# ccs –h 172.16.1.250 --lsnodes

Cikakke. Kun yi nasarar ƙirƙirar gungu da kanku kuma kun ƙara nodes biyu. Don ƙarin cikakkun bayanai game da zaɓuɓɓukan umarni na ccs, shigar da umarnin ccs-help kuma bincika cikakkun bayanai. Tunda yanzu kun san yadda ake ƙirƙirar cluster da ƙara nodes zuwa gare shi, Zan buga muku Part 03 nan ba da jimawa ba.

Na gode, har sai a ci gaba da haɗawa da Tecint don ingantacciyar hanyar yadda ake.
