Kodi kukhazikitsa ndi sintha Xen Server

Server Xen ndi nsanja odzipereka kuti zochita zake ntchito luso hardware virtualization. Dziwani kuti mu nkhani iyi simungapeze kusiyana kulikonse lofunika kwa ndondomeko dongosolo, koma mu nkhani iyi ntchito ndi wofanana ndi zokolola za makina lenileni, amene anapanga Nawonso achichepere izi wotchuka ntchito mu mapangidwe mafakitale.

ndi ubwino wotani?

Mwa ubwino waukulu ntchito Xen Server ndi kupereka zotsatirazi:

• A kuchepetsa kwambiri nthawi ndi kuvuta chitukuko cha virtualization kuti amaperekedwa popereka polumikizira hardware m'manja mwa alendo yoyenera.
• Tikuyambitsa ogwiritsa kuwonjezeka noticeable mu ntchito virtualisation nsanja chifukwa chakuti machitidwe alendo ukulamulidwa kudzera hypervisor ndi mwachindunji.
• nsanja oterowo zambiri kutetezedwa kusokonezedwa kunja, kuyambira ntchito kugawanika momveka bwino za makina pafupifupi okha, komanso kugwiritsa ntchito hardware. Ntchito iliyonse nsanja ikuchitika ufulu wonse kwa zipangizo zina, mwachitsanzo mayunitsi zonse ntchito mu malo ake ndi kugwiritsa ntchito payekha.
• Mwazina, Xen Server nsanja-analenga machitidwe osiyana alendo opaleshoni pa kompyuta khamu.

Ndi chiyani icho?

Ndi lokha Xen - ndi mtanda nsanja hypervisor. nsanja iyi ndi chitukuko wapadera, amene m'manja mwa University of Cambridge ndipo tsopano anagawira kokha chifukwa GPL-chiphatso. Poyamba anthu amapereka mwa nthambi zikuluzikulu ziwiri za mankhwala - Baibulo malonda ndi buku la malamulo gwero, koma mu 2009 zinanenedwa kuti zosankha zonse Xen Server adzakhala mwamtheradi mfulu, ndiye kudzakhala gwero ufulu.

Ganizo zofunika umenewu hypervisor ndi madambwe kuti kale Pre-anapezerapo buku la makina enieni. Kukachitika kuti wayamba kutsegulaso wonse malekezero ankalamulira anapanga wina watsopano pambuyo kutsegulaso. Ngakhale mu ndondomeko ya kusamuka kwa nkhani Xen Server liti liwonerere pakati pawo. Chifukwa ichi, m'kupita linakhalapo, pafupifupi makina pafupifupi akutsirizira mu ima pamzere pa zinthu zosiyanasiyana, koma Xen ukugwira ntchito kokha mwachindunji ndi mfundo ankalamulira, ndi china chirichonse chimadza kokha pambuyo zifika kupereka kasamalidwe ntchito, kupereka kulamulira hypervisor.

Chifukwa dongosolo chili ponseponse?

Lero tikhoza kunena kuti Citrix Xen Server ndi imodzi mwa machitidwe amphamvu kwambiri angathe hardware virtualization. Tikumbukenso kuti ndi yachangu ndi otetezedwa kwambiri chilengedwe cha mitundu yonse, koma ali chobalidwa mfulu kwathunthu. Koma, ndithudi, izo sizingakhoze kuti chisankho amazindikira chilengedwe mwamtheradi, choncho, mu zinthu zina, mapulogalamuwanso angathe amachita ena mitundu ya pulogalamu.

Kodi kukhazikitsa ndi sintha?

Citrix Xen Server lakonzedwa kupereka ntchito zosavuta machitidwe muyezo Mawindo ndi Linux ntchito. Dziwani kuti mukhoza kugwiritsa ntchito zina zimene mungachite nsanja, koma Mlengi safuna chitsimikizo kuti chidzakhala ntchito bwinobwino.

Koperani owona mukufunika mungathe ku malo boma la mapulogalamu, mu nkhani iyi Mpofunika chisanadze bwino Kunena mwachidule za ntchito ndi inakonza. Mukakhala kukopera Server Citrix Xen ndi akulemba kuti galimoto makamaka, mukhoza kulumikiza chipangizo kompyuta ndi kuyamba kugwira ntchito. Mwakucimbidza Dziwani kuti pa ndondomeko ya unsembe adzakhala kwathunthu kuchotsa mfundo iliyonse imene inu amasunga litayamba anu, kotero kuti ndikuganiza pasadakhale za momwe angatetezere zanu zachinsinsi.

Kenako mudzaona TV kuti chimakulimbikitsani kukhazikitsa Xen Server 6.2 (kapena buku lina lililonse ngati inu dawunilodi izo). Atawoloka zosavuta unsembe adzakhala kutseka zenera, kusonyeza nsanja onyamula unsembe zolondola.

Pambuyo yomaliza Nsapato Xen Server pa Ubuntu Server, kapena zina nsanja wosuta basi masiwichi kwa zenera chachikulu dongosolo kuthamanga. Ikukhala ngati zonse kunachitika zazikulu menyu yodzaza Xen-dongosolo, ndipo nthawi yomweyo lagawidwa ndi zipilala ziwiri, komwe pa madzere kusankha magawo zazikulu pogwiritsa ntchito makiyi muvi, pamene kumanja mudzaona mungachite izi zonse, mukhoza kugwiritsa ntchito kuti kusintha zina zimatha opaleshoni dongosolo. Kupita ku moyo woterewu, muyenera kusankha chinthu anakhumba ndi kumadula pa Lowani.

Pamene muli mu Xen Ubuntu Server Management zenera, mungathe kugwiritsa ntchito kiyibodi Simungachite alt + F3 kusinthana ndi muyezo kwa Linux kutonthoza amene kamodzinso zimatsimikizira kuti, palokha, nsanja iyi ndi muyezo Linux, zida ndi zipangizo zawo, ndipo bwinobwino ndipo ambiri adziwe malangizo akonzedwa. Ndi chifukwa chake anthu omwe Linux opaleshoni dongosolo, palibe zovuta kuti mwamsanga bwino mbali yaikulu ya ntchito ya nsanja iyi.

Sintha dongosolo

Ukangoyamba makina, ntchito adiresi lolingana adzatha kuyang'ana limasonyeza ziwiri zazikulu mu osatsegula. Pakuti munthu wina, inu mukhoza kukopera XenCenter, mwa ulamuliro umene wodzala nsanja, pokhala winayo ali ndi exe-file. Lang'anani, pambuyo unsembe, mudzakhala kuoneka kasamalidwe kutonthoza, mukalowa mu adiresi yanu makamu, ndi muzu achinsinsi, ndipo adzapatsidwa mwayi kwa dongosolo.

Kupeza zofunika

Mu mode muyezo, kuthamanga makamu, mukhoza kuona zonse zowerengera ndi luso zambiri, ndi perebiraniya totsegulira pamwamba pa kudzakhala kotheka kuti muwone kuti kwambiri za kaperekedwe zina zowonjezera ndi magawo. Mwachitsanzo, mu tsamba Magwiridwe, mukhoza kuona zokhuza mmene panopa yodzaza ndi khamu makina Xen Server, ndi analamula amene wachita kale, komanso mmene kugwiritsa ntchito zinthu zomwe zilipo.

Ikani mlendo

Ngati inu mukufuna kulemba dongosolo mlendo khamu, muyenera kupita mpaka Chatsopano VM kapena monga VM, ndipo pambuyo kutsegula kwa menyu chinthu ichi kusankha opaleshoni dongosolo mukufuna kukhazikitsa monga mlendo wake. Makamaka, ngati n'koyenera, akhoza ikuchitika unsembe wa Xen Server mu Mawindo 7. Dziwani chakuti nsanja iyi amapereka zosiyanasiyana mwachilungamo lonse, ndi ndondomeko unsembe pafupifupi zofanana ndi kuti ntchito VMware kaphatikizidwe kamakompyuta. Ndiko kuti, ndondomeko lagawidwa magawo angapo:

• kutayipa machitidwe kudziwika;
• atakhala nambala Napempha kwa mapurosesa ndi chikumbukiro;
• kumasulidwa kwa danga pa galimoto anu kapena odzipereka yosungirako sing'anga kwa unsembe m'dziko lake latsopano.

Ngati inu konse mu moyo wanga zinachitikira kwa VMware kaphatikizidwe kamakompyuta, dziwani kuti mosavuta kulowa ntchito yaikulu ndipo mudzakhala mosavuta kukhazikitsa anachita koyamba unsembe Xen Server pa Windows 7 kapena ena mitundu ya kachitidwe opaleshoni.

Kodi kuchita yotsatira?

Pambuyo munakonza ndi galimoto latsopano, ndondomeko kwasanduka muyezo ndithu kuti unsembe wa opaleshoni dongosolo mwasankha. Ndipo palibe zinthu zatsopano. ochepa okha kudikira mpaka mapeto mmene kukhazikitsa dongosolo latsopano, kenako mudzatha kuti tigwiritse ntchito kutonthoza mbali Xen yawonongeka. Deploying VDI kapena kukhazikitsa njira ina - zonse izi tsopano mwa mphamvu zanu, ndipo mungathe kugwiritsa ntchito dongosolo monga inu mukuona koyenera.

Mbali hardware

Musaiwale kuti ntchito dongosolo mwachindunji amadalira hardware ntchito inu. Ndi chifukwa chake choyamba pamaso munakonza mtambo aliyense ndi kupereka maseva kuti adzakhala ndondomeko virtualization.

Pofuna kuonetsetsa kusamuka mokwanira mofulumira pakati IBM osiyana monga gawo choona ntchito lophimba yapadera yomwe theoretically imathandizira kusamuka kwa nthawi 10, koma kuchita zimenezi ndi mathamangitsidwe ndi zochepa kwambiri. Pofuna kupereka mwayi kwa zopezera maseva ndi makina pafupifupi, ndi lophimba zina mukhoza zidzawonjezedwa kwa zikuchokera choona, chimene kutumiza magalimoto makasitomala akunja.

Komanso, chofunika ndi ntchito katundu uninterruptible mphamvuyi kuloleza zolondola kuchira ndondomeko pa makina ngati kulephera kwa yobweretsa chapakati mphamvu.

Kodi zikukhala makina?

Ndiye funso n'lakuti, kumene udzasugidwa makina enieni. Mu nthawi imeneyo iwo adzaikidwa chokhazikika pa maseva okha, ndi kungasokoneze kwambiri pa kudalirika chonse cha dongosolo lonse, monga mmene zolephera iliyonse muli kuti basi kutaya zonse makina pafupifupi ndinkakhala nalo pa kompyuta.

Komanso sitiyenera kuiwala kuti njira imeneyi komanso kwambiri kusokoneza wonse ntchito katundu akusamala, monga poyamba ayenera kupereka pafupifupi makina kusamuka kusuntha galimoto ake ena Seva zina, ndipo izi zonse amalenga m'malo yaitali ndiponso yosasangalatsa ndondomeko.

Pangani pafupifupi maukonde zomangamanga

Pofuna nokha kusinthasintha woyang'anira zoikamo zopezera makina pafupifupi, komanso kuonetsetsa kuti iwo sanali mu subnet limodzi ndi "Server Xen", muyenera kugwira kukhazikitsidwa kwa zomangamanga pafupifupi maukonde. Mu Citrix poyamba anaoneratu vutoli ndi anakamba DVSC, amene ankatsogoleranso monga makina pafupifupi, koma amagwiritsa ntchito kwambiri zochepa kukumbukira ndi chuma.

Mukapita mwachindunji the web-mawonekedwe a DVSC, inu mudzapeza pali zambiri ndithu mfundo zothandiza za zomangamanga maukonde, kuphatikizapo mndandanda wa makina pafupifupi kuti panopa anakwanitsa kulumikiza Intaneti makamaka, mitundu yonse ya mauthenga akutulukira zolakwa, komanso chintchito Intaneti ntchito si kokha kwa makina enieni pafupifupi, koma mfundo kwa maukonde lonse.

DVSC ntchito monga muyezo makhoma oteteza malamulo a sipangakhalenso anapereka kudzera AccessControl tsamba. Policy Network Security lagawidwa milingo anayi ndi malamulo amalola ife pofotokoza mtundu winawake wa kanthu, ndi protocol (sipangakhalenso anapereka kwa sender ndi wolandira madoko, komanso amasonyeza ndondomeko ya kudziwika), komanso ena amene lamulo ili idzagwira ntchito.
