DNS-configuration rau lub qhov rais thiab Linux. Yuav ua li cas mus saib hauv lub DNS chaw?

Nyob rau hauv hnub no tus lag luam los xyuas kom meej txog kev ntseeg thiab kev ruaj ntseg ntawm Internet sib txuas yog nce pib los mam muaj ntau yam ntawm cov kev pab cuam thiab, nyob rau hauv particular, yog ib tug tshwj xeeb qhov chaw yog muab rau tus DNS neeg rau zaub mov. Tej chaw xws servers rau ib tug ntau ntawm cov neeg yog heev lub sij hawm-siv ua hauj lwm. Txawm li cas los, nyob rau ntawm lub qhov tso zis koj tau txais ib tug tsis tshua txhim khu kev qha thiab ruaj ntseg servers uas muab cov kev pab tiv thaiv, thiab niam txiv ntawm lwm yam uas, xws li thaiv pliaj, teeb meem thiab txawm txaus ntshai websites.

Txawm li cas los, feem ntau lub caij tseem ceeb uas influences yuav ua li cas zoo yuav ua hauj lwm rau koj DNS - configuration ntawm cov neeg rau zaub mov uas koj xav mus ua ib tug meej heev yam.

Yuav ua li cas yog DNS?

DNS - yog ib tug tshwj xeeb faib system rau kev txiav txim lub xov ntawm lub numeric tus IP-qhov chaw nyob thiab lub npe. Tej hais yog lub feem ntau yooj yim nyob rau hauv cov nqe lus ntawm Machining tag nrho cov hom ntawm routing ntxhuav, tab sis nyob rau tib lub sij hawm - yog kiag li tsis tsim nyog rau kev siv pej xeem. Tom qab tag nrho, cov neeg nco ntsoov ib tug lossis loj tus naj npawb ntawm poob lawm ntawm tus xov tooj yog ntau yam ntxiv nyuaj tshaj nrog nuj nqis npe.

Chiv, nyob rau hauv thiaj li yuav piv sis, raws li zoo raws li yuav ua rau yooj yim rau cov neeg siv nws yog nws tus kheej lub DNS neeg rau zaub mov teeb, siv ib tug kev cai rooj nyob rau hauv uas ib tug xov xwm ntawm hais txog zauv chaw nyob rau ib tug neeg cov npe ntawm cov cav tov, thiab cov ntxhuav fwm rau hnub no thiab muaj kev koom siv los ntawm ntau yam qub daim ntaub ntawv. Nyob rau hauv kev, nws yog ib cov ntaub ntawv npe hu fwjchim luj kawg nkaus. Niaj hnub no, cov neeg feem coob yeej paub hais ntau yam Internet pab nyob rau hauv lawv cov sau npe, thiab xws li ib daim ntawv qhia no yeej muaj tseeb xwb tsis hais txog chaw nyob ntawm ntau cov websites, tab sis kuj rau e-mail chaw nyob.

Nyob rau hauv cov ntaub ntawv no, qhov chaw nyob rau hauv tej yam tseem ceeb rau txoj hauj lwm nws occupies ib tug neeg sau npe neeg rau zaub mov.

Yog vim li cas DNS-servers uas yuav tsum tau?

Yog li, peb yuav txhais tau lub hom phiaj tseem ceeb ntawm uas yog DNS neeg rau zaub mov configuration thiab nws ntxiv siv:

• Yog xav tau tshwj xeeb cov lus qhia txog cov IP-qhov chaw nyob ntawm ib lub neeg rau zaub mov, nyob rau hauv raws li nws lub npe, thiab vice versa.
• Routing ib tug txawv email.
• Muab tag nrho cov ntaub ntawv hais txog dab tsi lub servers yog pab rau tus network kev twg.

Yog vim li cas yog qhov tseeb qhov chaw?

Piv txwv li, nyob rau hauv Ubuntu DNS chaw ntawm ib lub ncauj lus kom ntxaws theem yuav tsum tau ib tug tej yam kev txawj ntse thiab ib tug tag nrho cov kev nkag siab txog dab tsi tshwm sim tawm cov los yog lwm qhov chaw. Nyob rau hauv cov ntaub ntawv no, nws yuav tsis mus tej kev hais lus txog xyaum, ua hloov cov neeg rau zaub mov nyob rau hauv ib qho kev lub tuam txhab. Tom qab tag nrho, yog Ubuntu DNS chaw yuav tsum nqa tawm nrog tsawg kawg ib tug ua pob liab vog txiav txim, rau tag nrho cov network ntawm lub tuam txhab yuav tsum tau ib tug me ntsis ntau tshaj ib tug loj tus naj npawb ntawm nyob ntawm tej, vim tsis muaj ib tug kev pab cuam yuav tsis ua hauj lwm kom zoo.

Tab sis ib tug ntau ntawm kev tso siab cov neeg siv nyiam mus rau hauv lub chaw los ntawm txhais tes. Thiab qhov no siv txawm mus xws li tej yam yooj yim tej yam uas raws li cov kev taw qhia ntawm tus IP-qhov chaw nyob, subnet daim npog qhov ncauj, thiab lub rooj vag chaw nyob, thiab DNS chaw rau lub computer. Tab sis nyob rau hauv qhov tseeb, muaj coob tus neeg tau ntev txij li thaum automate xws dab.

Linux (Ubuntu)

Nyob rau hauv Linux DNS configuration los ntawm kev siv resolvconf kev pab cuam, uas lub haum ntawm tsis yog nqa tawm nyob rau hauv lub hauv paus ntawm cov ntaub ntawv tau txais los ntawm ntau yam subsystems. Ib tug ntawm qhov tseem ceeb thaj chaw ntawm no innovation yog tias tam sim no lub system ntaub ntawv yog generated tag nrho cia li, thiab tsis ib lub zuj zus txhua qhov kev pab cuam uas koj xav tau los mus ua kom ntau kev hloov thiab siv ib qho programming interface. Li no, tej kev hloov mus rau cov ntaub ntawv no, koj yuav sim ua kom nws tus kheej, nws thiaj li cia li ploj.

Nyob rau hauv kev twb kev txuas nrog rau qhov no DNS ntaub ntawv npaj rau zoo li qub interfaces yuav tsum tau nkag mus rau hauv ib tug tshwj xeeb cov ntaub ntawv thiab lwm yam / network / interfaces nyob rau hauv lub seem nrhiav tsis, nameservers yog, raws li zoo raws li lub sau. Nyob rau hauv cov ntaub ntawv no, cov tsis yuav tsum yoog mus rau lub yam ntxwv teev nyob rau hauv resolv.conf.

debian

Yog hais tias koj xav tau rau Debian DNS teeb, txoj kev ua no tsis txawv ntawm qhov uas yog muab rau koj los ntawm lwm yam distributions. Koj yuav tsum tau ntxiv ib tug neeg tswv tsev lub npe thiab nws tus IP-qhov chaw nyob nyob rau hauv ib tug nyias muaj nyias ib cov ntaub ntawv thiab lwm yam / fwjchim luj kawg nkaus rau ntau yam zoo li qub queries. Yuav kom koj lub computer ces tsis tu ncua xa ntau yam kev thov rau qhov kev tsim nyog rau zaub mov, koj muaj peev xwm tsuas ntxiv qhov chaw nyob ntawm lub pab nyob rau hauv ib tug nyias muaj nyias ib cov ntaub ntawv thiab lwm yam / resolv.cong.

Piv txwv li, yog hais tias koj siv ib lub computer yuav nkag mus rau 192.168.1.1, lub uas yuav tsum muaj tsis tu ncua xa tag nrho cov hom ntawm queries rau ib DNS neeg rau zaub mov, ces cov hauv qab no kab yuav tsum tam sim no nyob rau hauv resolv.conf: nameserver 192.168.3.2.

Yog li, koj yuav hloov lub chaw ntawm DNS-servers nyob rau hauv tag nrho cov kev khiav hauj lwm systems. Nws yog ib qho tseem ceeb kom txhim tsa lub caij nyoog chaw nyob uas koj muab cov neeg teb xov tooj vim hais tias txwv tsis pub koj cia li yuav tsis tau txais ib kev twb kev txuas.
