Mataki 1: Ƙirƙirar Sabuwar Cibiyar Bayanai tare da Tari na Nodes Biyu

Ta hanyar tsoho, RHEVM ƙirƙira tsohuwar cibiyar bayanai tana ƙunshe da gungu mara komai mai suna Default a cikin muhallinmu na RHEV. Za mu ƙirƙiri sabuwa kuma mu ƙara runduna biyu (Pending Approval) a ƙarƙashinsa.

Bincika cibiyoyin bayanai na yanzu, ta zaɓi shafin cibiyoyin bayanai.

1. Danna Sabo don ƙara sabon cibiyar bayanai zuwa mahallin ku. Mayen taga kamar wannan zai bayyana, Cika shi kamar yadda aka nuna:

2. Za a umarce ka da ka ƙirƙiri sabon cluster ban da \Data-Center1 Danna (Configure Cluster) sannan ka cika kamar yadda aka nuna.

Muhimmi: Tabbatar cewa Nau'in CPU daidai ne ɗaya kuma DUKAN nodes suna da Nau'in CPU iri ɗaya. Kuna iya canza kowane saiti gwargwadon buƙatun muhallinku. Za a tattauna wasu saitunan dalla-dalla daga baya..

3. Danna (Configure Daga baya) don fita wizard.

4. Canja zuwa Mai watsa shiri shafin don amincewa da ƙara (Pending Approval) node zuwa muhallinmu. Zaɓi kumburin ku na farko kuma danna Amincewa.

5. Cika maye da ya bayyana tare da sabon halitta \Data-Center1 da gungu na farko kamar yadda aka nuna:

Muhimmi: Kuna iya ganin gargaɗi game da Gudanar da Wuta kawai ku tsallake shi ta danna Ok, maimaita matakan iri ɗaya tare da kumburi na biyu.
