Paskirstytos gedimams atsparios LeoFS objektų saugyklos, suderinamos su klientais naudojant S3, NFS, įdiegimas
Pagal Opennet: LeoFS — paskirstyta gedimams atspari objektų saugykla LeoFS, suderinamas su klientais, naudojantys Amazon S3 API ir REST-API, taip pat palaiko NFS serverio režimą. Yra optimizacijų saugoti tiek mažus, tiek labai didelius objektus, yra įmontuotas talpyklos mechanizmas, galimas saugyklos replikavimas tarp duomenų centrų. Projekto tikslai apima 99.9999999% patikimumą, naudojant perteklinį dublikatų replikavimą ir pašalinant vieną gedimo tašką. Projekto kodas parašytas erlangų kalba.
LeoFS susideda iš trijų komponentų:
LeoFS saugykla — aptarnauja objektų ir metaduomenų pridėjimo, gavimo ir ištrynimo operacijas, yra atsakingas už replikacijos, atkūrimo ir klientų užklausų pateikimą į eilę.
LeoFS vartai — aptarnauja HTTP užklausas ir peradresuoja atsakymus klientams naudojant REST-API arba S3-API, užtikrina reikalingiausių duomenų talpyklą atmintyje ir diske.
LeoFS vadybininkas — stebi LeoFS Gateway ir LeoFS Storage mazgų veikimą, stebi mazgų būseną ir tikrina kontrolines sumas. Garantuoja duomenų vientisumą ir aukštą saugyklos prieinamumą.
Šiame įraše mes įdiegsime Leofs naudodami ansible-playbook ir išbandysime S3, NFS.
Jei bandysite įdiegti „LeoFS“ naudodami oficialias žaidimų knygas, susidursite su įvairiomis klaidomis: 1,2. Šiame įraše parašysiu, ką reikia padaryti, kad šių klaidų būtų išvengta.
Ten, kur paleisite ansible-playbook, turite įdiegti netcat.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.

Use "s3.amazonaws.com" for S3 Endpoint and not modify it to the target Amazon S3.
S3 Endpoint [s3.amazonaws.com]:
Use "%(bucket)s.s3.amazonaws.com" to the target Amazon S3. "%(bucket)s" and "%(location)s" vars can be used
if the target S3 system supports dns based buckets.

Encryption password is used to protect your files from reading
by unauthorized persons while in transfer to S3
Encryption password:
Path to GPG program [/usr/bin/gpg]:
When using secure HTTPS protocol all communication with Amazon S3
servers is protected from 3rd party eavesdropping. This method is
slower than plain HTTP, and can only be proxied with Python 2.7 or newer
Use HTTPS protocol [No]:
On some networks all internet access must go through a HTTP proxy.
Try setting it here if you can't connect to S3 directly
