Kodi mungasankhe bwanji 777 pa Linux?

Njira yogwiritsira ntchito ndi gawo limodzi la kompyuta. Posachedwa, Linux OS yakhala yotchuka kwambiri ndi mitundu yosiyanasiyana ya Linux, chifukwa cha kugawidwa kwaulere ndi cholowa kuchokera ku Unix ya mfundo yogawana ufulu kwa wogwiritsa ntchito.

Chigawo chofunikira cha dongosolo lililonse ndi mafayilo. Ndipotu, zonse zomwe akugwiritsa ntchito zimasungidwa. Kupeza ufulu kwa mafayilo ndi mafoda kumapanga zomwe amavomereza kuchita munthu wina, potero amapanga maulendo oyenerera ndikuonetsetsa chitetezo cha dongosolo lonse. Kawirikawiri, kukhazikitsa ufulu wopezeka ndi kuwathandiza kapena kulepheretsa kuchita, kuwerenga, ndi kulemba.

Ogwiritsa Ntchito ndi Magulu

Kwa wogwiritsa ntchito aliyense, mawonekedwe opatsa ntchito amachititsa chizindikiro chake chodziwika. Mu "Linux" imatchedwa UID. Kuonjezerapo, kuti athetse mautumiki, ogwiritsa ntchito akuphatikizidwa palimodzi, omwe apatsidwa nambala yapadera ya GID.

Ogwiritsa ntchito onse "Linux" amapatulidwa m'magulu atatu:

• Wogwiritsa ntchito - mwini wa fayilo;
• Gulu ndi membala wa gulu lomwelo monga mwiniwake;
• Zina - zina zonse.

Pamene mukupeza fayilo, machitidwe opangira ntchito amatsimikizira ngati wogwiritsa ntchitoyo ndi a magulu ena. Mwachitsanzo, kasitomala amene amatumiza pempho ku malo kudzera mwa osatsegula adzalankhulidwa kwa winayo. Ngati mwini malo akugwirizanitsa kudzera pa FTP ndi dzina la mtumiki ndi mawu achinsinsi, adzapatsidwa kwa gulu la osuta.

Maudindo ofikira

Magulu ali ndi ufulu payekha omwe amawongolera kuchita ntchito ndi mafayilo monga kuwerenga, kutsegula kapena kusintha. Kwa aliyense wa iwo, pali mitundu itatu ya kupeza:

• Kuyamba;
• Kuwerenga;
• Kulemba kapena kusintha.

Zisonyezero zowerengera za ufulu

Kawirikawiri zimasonyeza kuti ndiwe woyenera kusintha, kuyamba kapena kuwerenga gulu lirilonse pogwiritsa ntchito mayina. Zotsatira izi zikugwiritsidwa ntchito:

• 4 - kuwerenga;
• 2 - mbiri;
• 1 - kuphedwa.

Mukutchulidwa kwa ufulu wowonjezera, monga lamulo, mawerengedwe atatu okha amagwiritsidwa ntchito. Woyamba amatsimikizira malamulo kwa mwini-wosuta, wachiwiri kwa gululo, ndi lachitatu kwa ena onse. Kugawira ufulu wina ku gulu lirilonse, malo amodzi omwe amawunikira kuwonjezereka kwa manambala. Mwachitsanzo, 7 imasonyeza kuti angathe kuphedwa, kulembedwa ndi kuwerenga, ndipo 6 imangosintha ndikuwerenga fayilo. Potero, zilolezo zopezeka ku Linux 777 monga lamulo, zomwe zimakulolani kuthamanga, kuwerenga ndi kubwereza fayilo kwa wosuta aliyense.

Zosintha zimasintha

Sinthani ufulu wopezeka ku "Linux" kokha mwiniwake kapena wogwiritsa ntchito yemwe ali ndi ufulu wolamulira. Kuti mupange kusintha kwa mawonekedwe a terminal, gwiritsani ntchito lamulo la chmod.

Zimayamba ndi magawo omwe amakulolani kusintha malamulo pogwiritsa ntchito malemba (zophiphiritsira) kapena malemba. Ganizirani momwe mungagwiritsire ntchito zilolezo 777, zomwe zimakulolani kuthamanga, kusintha, ndi kuwerenga fayilo kwa ogwiritsa ntchito onse. Muzolowera zamtundu, lamulo lidzawoneka monga: chmod 777 fayile , ndi chikhalidwe: chmod = = rwx filename .

Mwachizolowezi, mawonekedwe a digito nthawi zambiri amakhala ophweka. Ndiponsotu, ndi zosavuta kulemba 755 kusiyana ndi kukhazikitsa magawo a mwiniwake, gulu ndi ena ogwiritsa ntchito.

Kusintha Kwambiri kwa Ufulu

Lamulo la chmod lingagwiritsidwe ntchito mobwerezabwereza, zomwe zimakulolani kuti mulowetse ufulu wa mafayilo onse m'ndandanda ndi zowonjezera. Kuti muchite izi, gwiritsani ntchito -R kusintha.

Chitsanzo cha lamulo limene limasonyeza momwe mungakhalire zilolezo za 777 pa mafayilo omwe ali pakali pano ndi makalata ake:

Chmod-R 777 *.

Kupeza ufulu ndi maulendo

Kuphatikiza pa mafayilo, mukhoza kukhazikitsa zilolezo pazinthu. Pogwiritsa ntchito mayina awo (mbendera) amagwiritsidwa ntchito, koma khalidwe ndilosiyana. Choyimira chomwe chimalola kuŵerenga amalola wosuta kuti ayang'ane mndandanda wa zomwe zili mu foda, kuyika mbendera yapamwamba kumapangitsa kuti zitheke kupanga zinthu zatsopano m'ndandanda, ndikukhazikitsa njira yoyenera kukulowetsani kuti mulowe mu bukhulo.

Kusintha zilolezo za zolembera ndizofanana ndi mafayilo omwe ali ndi lamulo la chmod.

Chitsanzo:

Chmod 777 / nyumba / kuyesedwa.

Lamuloli pamwambapa likuwonetsa momwe mungakhazikitsire zilolezo za 777 zowonjezeramo / nyumba / mayeso.

Ufulu ndi ufulu wopeza

Tiyenera kukumbukira kuti kusungidwa kosayenerera kwa ufulu wowonjezera kungasokoneze kayendetsedwe ka kayendetsedwe kake kapena zinthu zina. Kuphatikiza apo, izo zingayambitse kulenga vuto lalikulu la chitetezo. Choncho, m'pofunika kuti musanthule ndikudziŵe zolembazo. Chisamaliro chachikulu chiyenera kuperekedwa kwa izi musanayambe zilolezo 777, pamene amalola aliyense wogwiritsa ntchito kupanga, kusintha ndi kutulutsa mafayilo m'ndandanda.

Ochita zigawenga zambiri za malo osokoneza malonda ndi zina zogwiritsira ntchito makina owonetsera amagwiritsira ntchito kunyalanyaza kwa ogwiritsa ntchito omwe mwalakwitsa anasiya ufulu wotsatsa ndikuchita zolemba kapena ntchito pa seva.

Ufulu Wowonjezedwa

Pali zochitika pamene kuli kofunikira kukhazikitsa ndondomeko yovuta yolumikizidwa. Pachifukwa ichi, maufulu "Linux" operekera machitidwe sangakhale okwanira. Ndiye mumayenera kugwiritsira ntchito makalata opangira mauthenga (ACLs). Gwiritsani ntchito ndondomekoyi pokhapokha mutagwiritsa ntchito makina aakulu kwambiri omwe angakhale ndi machitidwe osiyanasiyana. Nthawi zina, ntchito zowonongeka zowonongeka .
