A rèir : - stòradh stuth sgaoilte a tha fulang le lochdan , co-chòrdail ri teachdaichean a’ cleachdadh an Amazon S3 API agus REST-API, agus cuideachd a’ toirt taic do mhodh frithealaiche NFS. Tha optimizations ann airson a bhith a’ stòradh an dà chuid nithean beaga agus glè mhòr, tha inneal tasgadan togte ann, agus tha e comasach stòradh a dhèanamh eadar ionadan dàta. Tha amasan a’ phròiseict a’ toirt a-steach a bhith a’ coileanadh earbsachd 99.9999999% tro ath-riochdachadh gun fheum de dhùblaidhean agus cuir às do aon phuing fàiligeadh. Tha còd a’ phròiseict sgrìobhte ann an Erlang.
Tha trì pàirtean ann an LeoFS:
- - a’ frithealadh gnìomhachd cur-ris, faighinn air ais agus cuir às do nithean agus meata-dàta, le uallach airson ath-riochdachadh, faighinn air ais agus ciudha iarrtasan teachdaiche.
- - a’ frithealadh iarrtasan HTTP agus ag ath-stiùireadh fhreagairtean do luchd-dèiligidh a’ cleachdadh REST-API no S3-API, a’ dèanamh cinnteach gun tèid an dàta as motha a tha a dhìth mar chuimhne agus air diosc a thasgadh.
- - a’ cumail sùil air obrachadh nodan LeoFS Gateway agus LeoFS Storage, a’ cumail sùil air inbhe nodan agus a’ sgrùdadh checksums. A’ gealltainn ionracas dàta agus ruigsinneachd stòraidh àrd.
Anns an dreuchd seo stàlaidhidh sinn Leofs a’ cleachdadh ansible-playbook agus deuchainn S3, NFS.
Ma dh’ fheuchas tu ri LeoFS a stàladh a’ cleachdadh na leabhraichean cluiche oifigeil, thig thu tarsainn air grunn mhearachdan: ,. Anns an dreuchd seo sgrìobhaidh mi na dh'fheumar a dhèanamh gus na mearachdan sin a sheachnadh.
Far an ruith thu ansible-playbook, feumaidh tu netcat a stàladh.

Default Region [US]:
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

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
