Kev teeb tsa ntawm kev faib ua txhaum cai LeoFS cov khoom khaws cia, sib xws nrog cov neeg siv khoom siv S3, NFS

Raws li Opennet: LeoFS - faib khoom txhaum-tolerant khoom cia LeoFS, sib xws nrog cov neeg siv khoom siv Amazon S3 API thiab REST-API, thiab tseem txhawb NFS server hom. Muaj kev ua kom zoo rau kev khaws cia ob qho tib si me thiab loj heev, muaj cov txheej txheem caching built-in, thiab rov ua dua ntawm kev khaws cia ntawm cov chaw khaws ntaub ntawv yog ua tau. Cov phiaj xwm lub hom phiaj suav nrog kev ua tiav 99.9999999% kev ntseeg tau los ntawm kev rov ua dua tshiab ntawm cov duplicates thiab tshem tawm ib qho kev ua tsis tiav. Txoj haujlwm code yog sau hauv Erlang.

LeoFS muaj peb yam:

  • LeoFS Cia - ua haujlwm ntawm kev ntxiv, rov qab thiab tshem tawm cov khoom thiab cov metadata, yog lub luag haujlwm rau kev ua kom rov ua dua, rov qab thiab queuing cov neeg thov.
  • LeoFS Gateway - pabcuam HTTP thov thiab xa cov lus teb rau cov neeg siv khoom siv REST-API lossis S3-API, ua kom cov ntaub ntawv nrov tshaj plaws hauv lub cim xeeb thiab ntawm disk.
  • LeoFS Manager - saib xyuas kev ua haujlwm ntawm LeoFS Gateway thiab LeoFS Storage nodes, saib xyuas cov xwm txheej ntawm cov nodes thiab cov ntawv txheeb xyuas. Guarantes cov ntaub ntawv ncaj ncees thiab siab cia muaj.

Hauv cov ntawv tshaj tawm no peb yuav nruab Leofs siv ansible-playbook thiab sim S3, NFS.

Yog hais tias koj sim rau nruab LeoFS siv cov official playbooks, koj yuav ntsib ntau yam yuam kev: 1,2. Hauv tsab ntawv no kuv yuav sau dab tsi yuav tsum tau ua kom tsis txhob muaj qhov yuam kev no.

Qhov twg koj yuav khiav ansible-playbook, koj yuav tsum nruab netcat.

Kev npaj server

Disabling Selinux. Kuv vam tias cov zej zog yuav tsim Selinux cov cai rau LeoFS.

    - name: Install libselinux as prerequisite for SELinux Ansible module
      yum:
        name: "{{item}}"
        state: latest
      with_items:

      yum: name={{ item }} state=present
      with_items:
        - nmap-ncat
        - redhat-lsb-core

Tsim ib tus neeg siv leofs thiab ntxiv rau hauv pawg log

    - name: Create user leofs
      group:
        name: leofs
        state: present

    - name: Allow 'wheel' group to have passwordless sudo

Enter new values or accept defaults in brackets with Enter.
Refer to user manual for detailed description of all options.

Access key and Secret key are your identifiers for Amazon S3. Leave them empty for using the env variables.
Access Key [9c2615f32e81e6a1caf5]: 
Secret Key [8aaaa35c1ad78a2cbfa1a6cd49ba8aaeb3ba39eb]: 
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.
DNS-style bucket+hostname:port template for accessing a bucket [%(bucket)s.s3.amazonaws.com]: leofs

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
HTTP Proxy server name [172.26.9.180]: 
HTTP Proxy server port [8080]: 

New settings:
  Access Key: 9c2615f32e81e6a1caf5

  Encryption password: 
  Path to GPG program: /usr/bin/gpg
  Use HTTPS protocol: False
  HTTP Proxy server name: 172.26.9.180
  HTTP Proxy server port: 8080

Test access with supplied credentials? [Y/n] Y
Please wait, attempting to list all buckets...
Success. Your access key and secret key worked fine :-)

Now verifying that encryption works...
Not configured. Never mind.
