Aya optimasi pikeun nyimpen objék leutik sareng ageung, aya mékanisme cache anu diwangun, sareng réplikasi panyimpen antara pusat data mungkin. Tujuan proyék kalebet ngahontal réliabilitas 99.9999999% ngalangkungan réplikasi duplikat anu kaleuleuwihan sareng ngaleungitkeun hiji titik kagagalan. Kodeu proyék ditulis dina Erlang.
LeoFS diwangun ku tilu komponén:
- - ngalayanan operasi pikeun nambahkeun, retrieving jeung mupus objék jeung metadata, tanggung jawab pikeun ngalakukeun réplikasi, recovery jeung antrian requests klien.
- — ngalayanan pamundut HTTP sareng alihan réspon ka klien nganggo REST-API atanapi S3-API, mastikeun cache data anu paling diperyogikeun dina mémori sareng disk.
- - monitor operasi LeoFS Gateway jeung LeoFS Panyimpenan titik, mantau status titik jeung pariksa checksums. Ngajamin integritas data sareng kasadiaan panyimpenan anu luhur.
Dina tulisan ieu kami bakal masang Leofs nganggo ansible-playbook sareng uji S3, NFS.
Upami anjeun nyobian masang LeoFS nganggo playbook resmi, anjeun bakal mendakan sababaraha kasalahan: ,. Dina tulisan ieu kuring bakal nyerat naon anu kedah dilakukeun pikeun nyingkahan kasalahan ieu.
Dimana anjeun bakal ngajalankeun ansible-playbook, anjeun kedah masang netcat.

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

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
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
