Indlela ukwenza iimvumelwana 777 on Linux?

inkqubo yokusebenza - yinxalenye ebalulekileyo yayo nayiphi na ikhompyutha. Kutshanje, imakethi aphilileyo athandwa kakhulu Linux iinguqulelo, ngenxa ukugeleza yaye ilifa Unix Umgaqo kokwahlulwa amalungelo kumsebenzisi.

Yinxalenye yayo nayiphi na inkqubo ifayile. Ngapha koko, lonke ulwazi lomsebenzisi igcinwe kuzo. Awunamalungelo akugqithisela iifayile kunye neencwadi ezinenkcukacha sichaze oko zivumelekile izenzo ukuba enze umntu othile, ngaloo ndlela ukumisela amanqanaba ukufikelela kunye nokuqinisekisa ukhuseleko kwinkqubo yonke. Ngokuqhelekileyo, izivumelwano zonikelo lwezicwangciso kukuvumela okanye ukuvala ukubulawa ukufunda nokubhala.

Abasebenzisi kunye Groups

Umsebenzisi ngamnye kwenkqubo yokusebenza unikela into ebonakalisayo eyahlukileyo. I 'Linux "ibizwa ngokuba UID. Ukongeza, kuba lula kubasebenzisi zolawulo zidibene ngokwamaqela, nto leyo nayo wabelwe inani unique GID.

Bonke abasebenzisi "Linux" yahlulwe ngokwamaqela amathathu:

• umsebenzisi - umnikazi wefayile;
• iqela - ilungu leqela efanayo njengoko umnikazi;
• enye - bonke abanye.

Xa ifayile zingafumaneka indlela yokusebenza ibhaqa ubulungu somsebenzisi kwiqela. Ngokomzekelo, omnye umxhasi lowo wandithumayo isicelo kwisiza usebenzisa ibrawuza, uya eyabelwe enye. Ukuba umnini isiza elidityaniswe nge FTP ukuba ufake igama lomsebenzisi kunye negama eligqithisiweyo, iya babelwe iqela lomsebenzisi le.

iimvume

Amaqela ngamalungelo ngamnye elawula ithuba imisebenzi ifayile njenge ukufunda, qala okanye ukutshintsha. Kuba iseti ngalinye iintlobo ezintathu lokufikelela:

• ukuqala;
• ukufunda;
• ukubhala okanye uhlele.

amalungelo eziveza yamanani umbuso

Amaxesha amaninzi ngokwaneleyo ukubonisa utshintsho amalungelo, ukubaleka okanye ukufunda ukuze iqela ngalinye ngokusebenzisa imiqondiso yedijithali. Kulo mzekelo, sebenmzisa i parameters zilandelayo:

• - 4 ukufunda
• 2 - ukurekhoda;
• 1 - ukusebenza.

Le nokonyulwa zonikelo lwezicwangciso, njengoko umthetho, amanani amathathu kuphela. Eyokuqala le migaqo ibonisa kumsebenzisi umniniyo, esesibini eli qela, kwaye eyesithathu wonke umntu ongomnye. Ukuseta amalungelo athile ukuze iqela ngalinye ukuba ukubhenela ukongeza elula lwamanani. Umzekelo, 7 ibonisa ithuba sokubulala, ukubhala nokufunda, 6 ivumela kuphela ukuba ulungise uze ufunde fayile. Ngenxa yoko, iimvume 777 Linux ebona nje umthetho, nto leyo evumela ukuba ukubaleka, funda uze ubhale naluphi umsebenzisi.

iimvume

Utshintshe iimvume kwi "Linux" Kuphela umnini okanye umsebenzisi kunye namalungelo umlawuli. Ukwenza utshintsho indlela yesiphelo ukusebenzisa umyalelo fdopen.

It iyachiza iinketho ukutshintsha imigaqo ngokusebenzisa itekisi (fanekisela) okanye imiqondiso yedijithali. Cinga ukubeka indlela iimvume 777, ukuvumela ukuba ukubaleka, ulungise uze ufunde le fayile kubo bonke abasebenzisi. Kwimo amanani, iqela leengcali liya kukhangela ngolu hlobo: fdopen 777 Igama lefayile, kwaye umlinganiswa: fdopen a = rwx lefayile.

Ukuziqhelisa, imowudi ye-digital ngokufuthi lula kakhulu. Ngapha koko, 755 kulula ukubhala ngaphezu ukuseta parameters ezithile umnini, iqela kunye nabanye.

Recursively ukuguqula amalungelo

I Sukwenza umyalelo fdopen ingasetyenziswa ngendlela imo recursive ekuvumela ukuba utshintshe amalungelo zonke iifayile kulawulo kunye sub-abasezantsi. Ukulungiselela le njongo -R iqhosha.

Umyalelo umzekelo ubonisa ukumisa indlela iimvume 777 kuzo zonke iifayile kulawulo lwangoku kunye beefayili yayo;

fdopen -R 777 *.

Iimvume kunye nezalathisi

Ukongeza iifayile, ungaseta iimvume labobalawuli akufuneki. Jonga kubo usebenzisa enye i parameters (iiflegi), kodwa ukuziphatha yahlukile nje kancinane. Option ukuvumela ukufunda, kuvumela umsebenzisi ukuba ukujonga uluhlu umpakati wolawulo, emisela ukurekhodwa iflegi likuvumela ukuba ukwenza izinto ezintsha kuvimba weefayili, bekunye amalungelo kubulawa ukuvumela ukuba ungene kwi weefayili.

Utshintshe iimvume kulawulo kwenziwa ngendlela efanayo kwifayile usebenzisa umyalelo fdopen.

umzekelo:

fdopen 777 / home / uvavanyo.

Umyalelo ilandelayo ibonisa ukumisa indlela iimvume 777 ku lawulo / home / uvavanyo.

amalungelo Ukhuseleko ukufikelela

Khumbula ukuba ufakelo ngokungafanelekanga amalungelo okufikelela uphazamise nkqubo okanye imithombo ngabanye. Ngaphezu koko, oko kunokubangela iingxaki ezinkulu ezinxulumene nokhuselo. Kuyimfuneko ke ngoko ukuba iphonononge kwaye kwakhona uxwebhu. ingqalelo ekhethekileyo kufuneka ihlawulwe oku ngaphambili ukufaka 777 zonikelo lwezicwangciso, njengoko avumele nabani na ukuba ukudala, ulungise, kwaye kwenza iifayile kwisilawuli.

Abahlaseli abaninzi ukungena kumaziko Web kunye neminye imithombo network isetyenziswa ngokungakhathali kubasebenzisi ngempazamo ekhohlo ekunene, ukuvumela ukukhuphela aze aphumeze nasiphi script okanye isicelo kwi umncedisi.

imvume Advanced

Kukho iimeko apho kufuneka kuphunyezwe inkqubo entsonkothileyo lokufikelela kulwazi. Kulo mzekelo, imithetho umgangatho kwinkqubo yokusebenza "Linux" kunokunganeli. Emva koko kufuneka babhenele ukusetyenziswa ngoluhlu lolawulo lonikezelo (ACL). Sebenzisa eli cebo kuphela bebenabahlobo abaninzi kakhulu schemes ukufikelela-level multi. Kwezinye iimeko, iindleko esezantsi imisebenzi inkqubo yokusebenza.
