🥇 Gosod storfa wrthrychau dosbarthedig sy'n goddef namau LeoFS sy'n gydnaws â chleientiaid sy'n defnyddio S3, NFS

Yn ôl Rhwyd agored: LeoFS — storio gwrthrychau gwasgaredig sy'n goddef namau LeoFS, yn gydnaws â chleientiaid sy'n defnyddio'r Amazon S3 API a REST-API, ac mae hefyd yn cefnogi modd gweinydd NFS. Mae yna optimeiddiadau ar gyfer storio gwrthrychau bach a mawr iawn, mae yna fecanwaith storio mewnol, ac mae'n bosibl dyblygu storio rhwng canolfannau data. Mae nodau'r prosiect yn cynnwys cyflawni 99.9999999% o ddibynadwyedd trwy atgynhyrchu copïau dyblyg yn ddiangen a dileu un pwynt methiant. Mae cod y prosiect wedi'i ysgrifennu yn Erlang.

Mae LeoFS yn cynnwys tair cydran:

Storio LeoFS — yn gwasanaethu gweithrediadau o ychwanegu, adalw a dileu gwrthrychau a metadata, yn gyfrifol am berfformio atgynhyrchu, adfer a ciwio ceisiadau cleient.
Porth LeoFS - yn gwasanaethu ceisiadau HTTP ac yn ailgyfeirio ymatebion i gleientiaid gan ddefnyddio REST-API neu S3-API, yn sicrhau bod y data mwyaf poblogaidd yn cael ei storio yn y cof ac ar ddisg.
Rheolwr LeoFS — yn monitro gweithrediad nodau LeoFS Gateway a Storage LeoFS, yn monitro statws nodau ac yn gwirio symiau gwirio. Yn gwarantu cywirdeb data ac argaeledd storio uchel.

Yn y swydd hon byddwn yn gosod Leofs gan ddefnyddio ansible-playbook a phrofi S3, NFS.

Os ceisiwch osod LeoFS gan ddefnyddio'r llyfrau chwarae swyddogol, fe welwch wallau amrywiol: 1,2. Yn y swydd hon byddaf yn ysgrifennu beth sydd angen ei wneud i osgoi'r camgymeriadau hyn.

Lle byddwch chi'n rhedeg ansible-playbook, mae angen i chi osod netcat.
