Phau ntawv qhia no yuav qhia koj txog 5 lus txib raws li nram no:
- hostname
- domain
- ypdomainname
- nisdomainname
- dnsdomainname
Lub naj npawb rau kev qhuab qhia
Txhua lub computer muaj lub hostname thiab koj lub computer's hostname yog yuav tau teeb tsa thaum koj thawj ntsia Linux.
Koj tuaj yeem paub koj lub computer hostname los ntawm kev khiav cov lus hais hauv qab no hauv qhov chaw davhlau ya nyob twg.
hostname
Hauv kuv tsev neeg qhov kev tshwm sim yog ib qho yooj yim "kev txiav txim siab".
Rau qee cov cav tov koj lub npe hostname yuav qhia tau ua ib yam zoo li no "computername.computerdomain".
Lub hostname yog siv los txheeb xyuas koj lub computer ntawm lub network thiab tus sau tias nws belongs rau.
Koj tuaj yeem tau txais lub npe ntawm lub computer rov qab los ntawm khiav cov lus qhia nram qab no:
hostname -siab
Xwb koj tuaj yeem tau txais tus sau npe xwb los ntawm kev ua raws li cov lus txib no:
hostname -d
Qhov kev hais kom ua yog
Siv tsis siv lub hostname nrog rho tawm d hloov rov qab rau koj lub npe sau npe koj tuaj yeem khiav ntawm cov lus txib nram qab no:
domain
Yog hais tias koj muaj tus sau teeb nws yuav xa rov qab koj yuav pom cov ntawv nyeem (tsis muaj).
Qhov hais kom ua tus sau xa rov qab xa cov npe NIS no lub npe. Yog li cas NIS sau npe?
NIS stands rau Network Information System. Phau ntawv qhia no taw qhia txog NIS raws li hauv qab no:
NIS yog tus Txheej Txheem Qhib Cov Kev Tiv Thaiv (RPC) -ntshov tus neeg siv / tus neeg ua haujlwm rau cov neeg ua haujlwm uas tso cai rau ib pawg ntawm cov tswvcuab hauv NIS sau los koom nrog cov txheej txheem cov qauv ntaub ntawv. Qhov no tso cai rau tus neeg khiav dej num txhawm rau teeb tsa NIS tus neeg siv nrog cov qauv ntaub ntawv tsawg heev thiab ntxiv, tshem, lossis hloov kho cov ntaub ntawv los ntawm ib qho chaw.
Ypdomainname Command
Lub YPDomainName ua tau qhia txog tib yam ntaub ntawv ua raws li qhov kev hais kom ua. Sim ua rau koj tus kheej los ntawm sau cov nram qab no rau hauv qhov chaw davhlau ya nyob twg:
ypdomainname
Li ntawd, vim li cas thiaj muaj ntau yam commands rau qhov qub tshaj plaws?
YP yog npe rau Yellow Pages, tiam sis yuav tsum tau hloov vim yog kev cai lij choj. Qhov no tau hloov mus rau NIS uas tau hais hauv tshooj dhau los.
Koj tuaj yeem siv ypdomainname yog tias koj xav tau, tiam sis koj yuav zoo li txuag koj lub ntsis ntiv tes rau kev siv zog thiab tawm tsam tias RSI tawm ntawm nws mus rau npe xwb.
Cov Txij Nkawm Thaj Chaw
Lub ntsiab lus qhia kuj qhia txog tib yam lus qhia raws li qhov kev sib txuas lus. Raws li koj yuav tau sau los ntawm cov khej yav dhau los tau siv los ua nplooj ntawv daj nplooj ntawv uas yuav rov qab los ntawm kev siv cov lus ypdomainname.
Cov nplooj ntawv ntawm nplooj ntawv daj tau hloov mus rau cov ntaub ntawv hauv lub network (NIS) thiab yog li ntawd tus tub txib tau hais txog.
Qhov kev hais kom ua yog qhov tau tsim kom yooj yim rau kev siv.
Koj tuaj yeem siv cov lus sam hwm rau hauv qab no:
nisdomainname
Qhov kev txheeb xyuas tau yuav zoo ib yam li qhov hais kom ua.
Dnsdomainname Command
Cov lus txib dnsdomainname rov sau npe DNS cov npe. Koj tuaj yeem khiav los ntawm typing cov nram qab no rau hauv davhlau ya nyob twg:
dnsdomainname
DNS stands rau Domain Name Server thiab nws yog siv los ntawm internet los hloov tus IP chaw nyob tiag tiag cov npe. Tsis muaj cov npe sau peb txhua tus yuav siv cov ntawv loj loj los ua haujlwm kom paub tias 207.241.148.82 yuav coj peb mus rau linux.about.com.
Qhov yuav zoo tshaj yog tias tshwj tsis yog tias koj tab tom khiav lub web neeg rau zaub mov koj lub computer yuav tsis muaj lub npe DNS thiab khiav dnsdomainname hais kom ua tsis muaj dab tsi.
Qhov Chaw NIS Lub Npe Lub Npe
Koj tuaj yeem teev NIS lub npe rau koj lub computer siv cov lus qhia nram qab no:
sudo domain npe mydomainname
Koj yuav xav tau sudo mus elevate koj cov cai.
Koj kuj tuaj yeem siv cov ypdomainname thiab cov lus qhia ua raws li hauv qab no:
sudo ypdomainname mydomainname
sudo nisdomainname mydomainname
Lub / etc / hosts Cov Ntaub Ntawv
Nyob rau hauv lub davhlau ya davhlau hluav taws xob khiav ua raws li cov lus hais hauv qab no kom qhib cov ntaub ntawv pub rau hauv cov nano editor:
sudo nano / etc / hosts
Yuav muaj ntau txoj kab ntawm cov ntawv nyeem / etc / hosts ua raws li hauv qab no:
127.0.0.1 localhost
Qhov thib ib yog qhov chaw nyob ntawm lub computer, qhov thib ob yog lub npe ntawm lub computer. Mus txuas ntxiv ntxiv ib qho NIS sau rau lub koos pis hloov kab raws li nram no:
127.0.0.1 localhost.yourdomainname
Koj tseem tuaj yeem ntxiv cov neeg tuaj yeem raws li hauv qab no:
127.0.0.1 localhost.yourdomainname mycomputer mylinuxcomputer
Lus qhia ntxiv txog Kev sau npe ua haujlwm
Kev hais kom ua tus sau npe muaj ntau cov keyboards raws li nram no:
domain name -a
Qhov no yuav xa cov aliases rau tus sau npe hauv hostfile.
domain name -b
Tus sau lub npe uas yuav siv tau yog tias tsis muaj lwm qhov teeb tsa.
Koj tuaj yeem npaj lub npe rau npe uas yuav raug siv qhov kev hloov saum toj no los ntawm kev qhia lub npe ua ib feem ntawm cov kab lus hais raws li hauv qab no:
domain name -b mydomainname
Nov yog qee cov lus ntxiv:
- domainname -d - DNS sau npe
- domainname - f - Lub npe ntev ntev
- domainname -F - nyeem cov lus qhia lub npe ntawm ib daim ntawv
- domainname -i - IP chaw rau lub npe party
- domainname -I - Txhua qhov chaw rau tus tswv tsev
- domainname -sub - Lub npe luv luv
- domainname -y-NIS / YP sau npe
