Malingana ndi : - kugawa zinthu zololera zolakwika , yogwirizana ndi makasitomala omwe amagwiritsa ntchito Amazon S3 API ndi REST-API, komanso imathandizira seva ya NFS. Pali kukhathamiritsa kwa kusunga zinthu zazing'ono komanso zazikulu kwambiri, pali njira yosungiramo yosungiramo, ndipo kubwereza kosungirako pakati pa malo a data ndikotheka. Zolinga za polojekitiyi zikuphatikiza kukwaniritsa kudalirika kwa 99.9999999% mwa kubwerezabwereza kobwerezabwereza ndikuchotsa mfundo imodzi yolephera. Khodi ya polojekitiyi idalembedwa ku Erlang.
LeoFS ili ndi zigawo zitatu:
- - imagwira ntchito powonjezera, kubweza ndi kuchotsa zinthu ndi metadata, ili ndi udindo wobwerezabwereza, kuchira ndi kutsata zopempha zamakasitomala.
- - imathandizira zopempha za HTTP ndikuwongoleranso mayankho kwa makasitomala pogwiritsa ntchito REST-API kapena S3-API, imatsimikizira kusungitsa deta yomwe ikufunika kwambiri pamtima ndi pa disk.
- - imayang'anira magwiridwe antchito a LeoFS Gateway ndi LeoFS Storage node, imayang'anira momwe ma node alili ndikuwunika macheke. Zimatsimikizira kukhulupirika kwa data ndi kupezeka kosungirako kwakukulu.
Mu positi iyi tiyika Leofs pogwiritsa ntchito ansible-playbook ndikuyesa S3, NFS.
Mukayesa kukhazikitsa LeoFS pogwiritsa ntchito mabuku ovomerezeka, mudzakumana ndi zolakwika zosiyanasiyana: ,. Mu positi iyi ndilemba zomwe ziyenera kuchitika kuti tipewe zolakwika izi.
Kumene mungayendetse ansible-playbook, muyenera kukhazikitsa netcat.

S3 Endpoint [s3.amazonaws.com]:

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.
