KVM (i raro i)VDI me nga miihini mariko tuku ma te whakamahi i te bash

Ko wai tenei tuhinga e whai ana?

Ko tenei tuhinga ka pai ki nga kaiwhakahaere punaha e pa ana ki te mahi ki te hanga i tetahi ratonga o nga waahi mahi "kotahi wa".

Prologue

I tonohia te tari tautoko IT o tetahi kamupene rangatahi e whanake haere ana me te whatunga rohe iti ki te whakarite "teihana mahi-whaiaro" hei whakamahi ma o raatau kaihoko o waho. Ko te tikanga ka whakamahia enei teihana mo te rehitatanga i runga i nga tomokanga o waho o nga kamupene, te tango raraunga mai i nga taputapu o waho, me te mahi tahi me nga tomokanga o te kawanatanga.

Ko tetahi waahanga nui ko te meka ko te nuinga o nga raupaparorohiko he "whakaritea" mo MS Windows (hei tauira, "Whakapuakitanga"), ahakoa te neke ki nga whakatakotoranga tuwhera, kei te noho tonu a MS Office te paerewa matua mo te whakawhiti tuhinga hiko. No reira, kaore i taea e matou te whakakore i a MS Windows i te wa e whakaoti ana i tenei raru.

Ko te raru nui ko te kohi raraunga rereke mai i nga huihuinga kaiwhakamahi, tera pea ka rere ke atu ki nga roopu tuatoru. Ko tenei ahuatanga kua rahua te MFC. Engari kaore i rite ki te quasi-state (te mana motuhake o te kawanatanga) MFC, ka nui atu te whiunga o nga whakahaere ehara i te kawanatanga mo enei ngoikoretanga. Ko te raruraru tino nui e whai ake nei ko te hiahia ki te mahi me nga purongo rokiroki o waho, ka mau tonu he paihere kino kino. Ko te tupono o te kawemai mai i te kino mai i te Ipurangi i kiia he iti ake na te aukati i te uru ki te Ipurangi ma te whakamahi i te rarangi ma o nga wahitau i uru mai nga kaimahi mai i etahi atu tari ki te whakawhanaketanga o nga whakaritenga, te whakauru i o raatau hiahia me o raatau hiahia, ko nga whakaritenga whakamutunga ka titiro. penei:

Nga whakaritenga haumarutanga korero

  • I muri i te whakamahinga, me whakakore nga raraunga kaiwhakamahi katoa (tae atu ki nga konae rangitahi me nga taviri rehita).
  • Ko nga tukanga katoa i whakarewahia e te kaiwhakamahi me whakamutu i te otinga o te mahi.
  • Te uru ipurangi ma te whakamahi i te rarangi ma o nga wahitau.
  • Nga here mo te kaha ki te whakahaere i te waehere tuatoru.
  • Mena kei te noho mangere te waahi mo te neke atu i te 5 meneti, me mutu aunoa te waahi ka horoi te teihana i a ia ano.

Nga whakaritenga a nga kaihoko

  • Ko te maha o nga teihana kiritaki mo ia peka kaua e neke ake i te 4.
  • Te wa tatari iti mo te punaha kia reri, mai i te wa i "noho" koe ki te timatanga o te mahi me te rorohiko a te kiritaki.
  • Ka taea te hono atu i nga taputapu peripheral (nga karapa, nga puku kohiko) mai i te waahi whakaurunga o te "teihana mahi-whaiaro".
  • Nga hiahia o te kaihoko
  • Te whakaatu i nga rauemi panui (whakaahua) i te wa e mangere ana te matatini.

Nga mamae o te mahi auaha

I te maha o nga takaro me nga livecds Windows, ka whakatauhia e matou ko te otinga kaore e pai ki te 3 nga tohu whakahirahira. He roa te waa ki te utaina, kaore ranei i te tino ora, ko o raatau whakaritenga i pa ki nga mamae mohoao. Kaore pea matou i rapu pai, ka taea e koe te taunaki i tetahi huinga taputapu, ka mihi ahau.

Na ka anga matou ki te titiro ki te VDI, engari mo tenei mahi ko te nuinga o nga otinga he nui rawa te utu, me aro nui ranei. Engari i hiahia ahau ki tetahi taputapu ngawari, me te iti o te makutu, ko te nuinga o nga raru ka taea te whakatau ma te whakaara ano / whakaara ano i te ratonga. Waimarie, i a matou he taputapu tūmau, he karaehe iti-mutunga i roto i nga manga, mai i te ratonga kua whakakorehia, ka taea e matou te whakamahi mo te turanga hangarau.

He aha te mea i tupu i te mutunga? Engari kaore e taea e au te korero ki a koe he aha te mea i puta i te mutunga, na te mea ko te NDA, engari i roto i te mahi rapu i whakawhanakehia e matou he kaupapa whakamere i whakaatu pai i roto i nga whakamatautau taiwhanga, ahakoa kaore i uru ki te mahi.

He torutoru nga whakahē: kaore te kaituhi e kii ana ko te otinga e whakaarohia ana ka whakaoti katoa i nga raruraru kua tohua, ka mahi i runga i te hiahia me te waiata. E whakaae ana te kaituhi i mua ki te korero ko Sein Englishe sprache he zehr schlecht. I te mea kaore i te whakawhanakehia te otinga, kaore e taea e koe te tatau i runga i te whakatika pepeha, i te whakarereketanga ranei o te mahi, kei o ringaringa nga mea katoa. Kei te whakaaro te kaituhi kei te mohio koe ki te KVM me te panui i tetahi tuhinga arotake mo te kawa Spice me te mahi iti me Centos tetahi atu tohatoha GNU Linux ranei.

I roto i tēnei tuhinga, e hiahia ana ahau ki te tūhura i te kaupapa matua o te otinga ka puta, inā koa te taunekeneke kiritaki-tūmau me te mauri o ngā tukanga huringa ora o te mīhini mariko i roto i te otinga. Mena he mea nui te tuhinga ki te marea, ka whakaahuahia e au ngā taipitopito whakatinanatanga o ngā whakaahua ora mō te hanga kiritaki angiangi e hangai ana ki Fedora, ā, ka matapakihia ngā taipitopito o te whirihora i ngā mīhini mariko me Ngā tūmau KVM hei whakapai ake i te mahi me te haumarutanga.

Mena ka tango koe i te pepa tae,
Te peita, te paraihe me te kāpia,
A he iti ake nga pukenga ...
Ka taea e koe te hanga i te rau rubles!

Te hoahoa me te whakaahuatanga o te pae whakamatautau

KVM (i raro i)VDI me nga miihini mariko tuku ma te whakamahi i te bash

Ko nga taputapu katoa kei roto i te whatunga peka, ko te hongere Ipurangi anake ka puta ki waho. I mua kua noho he tūmau takawaenga; Engari kei runga, i roto i era atu mea, ko te tātari o nga waka mai i nga miihini mariko (abbr. VM i raro i te tuhinga) ka puta. Kaore he mea hei aukati i a koe ki te tuku i tenei ratonga ki runga i te tūmau KVM ko te mea anake e hiahia ana koe ki te mataki ko te pehea te whakarereketanga o te uta o te punaha iti.

Ko te Teihana Kiritaki he "teihana mahi-whaiaro", te "mutunga o mua" o ta maatau ratonga. Ko Lenovo IdeaCentre nettops. He aha te pai o tenei waahanga? Ae, tata ki te katoa, tino koa ki te maha o nga hononga USB me te kaipanui kaari kei te papa o mua. I roto i ta maatau kaupapa, ka whakauruhia he kaari SD me te whakamarumaru tuhi taputapu kua whakauruhia ki roto i te kaari kaata, ka tuhia he ahua ora o Fedora 28 Ae ra, ka honoa he kaitirotiro, papapātuhi me te kiore ki te kupenga.

Ko te Whakawhiti he whakakā taputapu taumata tuarua, e tu ana i roto i te rūma tūmau me nga rama kimo. Kaore e hono ana ki etahi atu whatunga atu i te kupenga o "teihana mahi-whaiaro".

Ko KVM_Server te matua o te kaupapa; i roto i nga whakamatautau pae, ko te Core 2 Quad Q9650 me te 8 GB o te RAM i tautoko maia i nga miihini mariko e 3 me Windows 10. Punaharoto kōpae – adaptec 3405 2 kōpae Raid 1 + SSD. I roto i nga whakamatautau mara o te Xeon 1220, ko te LSI 9260 + SSD tino kaha ake te tautoko i te 5-6 VM. Ka whiwhi matou i nga kaitoro mai i te ratonga kua reti; Ko tenei (ng) tūmau he punaha mariko KVM kua tukuna me te puna wai miihini mariko_Vm.

He miihini mariko a Vm, te tuara o ta maatau ratonga. Kei reira nga mahi a te kaiwhakamahi.

Ko te Enp5s0 he atanga whatunga e anga atu ana ki te whatunga o "teihana mahi-whaiaro", dhcpd, ntpd, httpd e noho ana ki runga, ka whakarongo a xinetd ki te tauranga "tohu".

Ko Lo0 he atanga pseudo loopback. Paerewa.

Spice_console – He mea tino whakamere, ko te mea, kaore i rite ki te RDP matarohia, ka whakawhanuihia e koe te paihere kawa KVM+Spice, ka puta mai he hinonga taapiri - te tauranga papatohu o te miihini mariko. Ko te tikanga, ma te hono atu ki tenei tauranga TCP, ka whiwhi tatou i te papatohu Vm, me te kore e hono atu ki a Vm ma tana atanga whatunga. Ka whakahaeretia e te tūmau nga taunekeneke katoa me Vm mo te tuku tohu. Ko te taurite tata ki te mahi ko IPKVM. Ko era. Ko te ahua o te kaitirotiro VM ka tukuna ki tenei tauranga, ka tukuna ano nga korero mo te nekehanga kiore ki a ia, a (ko te mea tino nui) ko te taunekeneke ma te kawa Spice ka taea e koe te huri i nga taputapu USB ki te miihini mariko, me te mea kei te hono tenei taputapu. ki te Vm ano. I whakamatauria mo nga puku kohiko, nga matawai, nga kamera tukutuku.

Ko nga kaari whatunga mariko Vnet0, virbr0 me Vm he whatunga miihini mariko.

Pehea te mahi

Mai i te Teihana Kiritaki

Ko nga huu teihana kiritaki i roto i te aratau kauwhata mai i te ahua ora o Fedora 28, ka whiwhi i tetahi wahitau IP ma te dhcp mai i te mokowā wāhitau whatunga 169.254.24.0/24. I te wa o te tangohanga, ka hangaia nga ture paahi ahi e tuku ana i nga hononga ki nga tauranga "tohu" me te "karakia" o te tūmau. Ka oti te tango, ka tatari te teihana mo te kaiwhakamahi "Kaihoko" ki te whakamana. Whai muri i te whakamanatanga a te kaiwhakamahi, ka whakarewahia te kaiwhakahaere papamahi "pouaka tuwhera" ka mahia te tuhinga autostart mo te kaiwhakamahi whai mana. I roto i etahi atu mea, ka whakahaerehia e te tuhinga autorun te tuhinga mamao.sh.

Whakaahuatanga o nga taurangi kōnae client.conf
server_ip — KVM_Server wāhitau
vdi_signal_port - KVM_Server tauranga kei reira te xinetd "noho"
vdi_spice_port — Tauranga whatunga KVM_Server ka tukuna te tono hononga mai i te kiritaki kaitirotiro mamao ki te tauranga kakara o te Vm whakatapua (nga korero kei raro nei)
animation_folder - te kōpaki i tangohia mai ai nga whakaahua mo te whakaaturanga pakiwaituhi
background_folder - te kōpaki i tangohia ai nga whakaahua mo te whakaatu whakaaturanga i te aratau tatari. Ko etahi atu korero mo te hākoritanga kei te waahanga o muri o te tuhinga.

Ko te tuhinga mamao.sh ka tango i nga tautuhinga mai i te konae whirihoranga /etc/client.conf me te whakamahi i te nc ki te hono atu ki te tauranga "vdi_signal_port" o te tūmau KVM ka whiwhi i te awa raraunga mai i te tūmau, kei roto i a ia e tatari ana ki nga rarangi "RULE ADDED , Hono atu inaianei”. Ina tae mai te aho e hiahiatia ana, ka whakarewahia te mahinga kaitirotiro-mamao ki te aratau kiosk, ka whakatuu hononga ki te tauranga tūmau "vdi_spice_port". Ka whakatārewahia te mahi hōtuhi kia mutu ra ano te mahi a te kaitirotiro-mamao.

Ko te kaitirotiro-mamao e hono ana ki te tauranga "vdi_spice_port", na te hurihanga i te taha tūmau, ka tae ki te tauranga "spice_console" o te atanga lo0, i.e. ki te papatohu miihini mariko ka puta tika te mahi a te kaiwhakamahi. I te wa e tatari ana mo te hononga, ka whakaatuhia te kaiwhakamahi ki te pakiwaituhi bullshit, i te ahua o te whakaaturanga kiriata o nga konae jpeg, ko te huarahi ki te raarangi me nga pikitia ka whakatauhia e te uara o te huringa animation_folder mai i te konae whirihoranga.

Mena kua ngaro te hononga ki te tauranga "spice_console" o te miihini mariko, e tohu ana i te katinga/whakahoutanga o te miihini mariko (arā, ko te mutunga tonu o te waahi kaiwhakamahi), ka mutu nga tukanga katoa e whakahaere ana mo te kaiwhakamahi whai mana, e arahi ana. ki te whakaara ano i te lightdm me te hoki ki te mata whakamana.

Mai i te taha KVM Server

I runga i te tauranga "tohu" o te kaari whatunga, kei te tatari a enp5s0 kia hono atu a xinetd. Whai muri i te hono ki te tauranga "tohu", ka whakarewahia e xinetd te tuhinga vm_manager.sh me te kore e tuku i nga tawhā whakauru me te tuku ano i te hua o te tuhinga ki te waahi Kiritaki nc.

Ko te tukanga o te hanga i tetahi miihini mariko hou

Ko te tuhinga vm_create.sh e panui ana i te uara o te taurangi "base_host" mai i te konae whirihoranga, e whakatau ana i te tauira miihini mariko i runga i te kaupapa ka mahia te kiore. Ka tangohia e ia te whirihoranga xml o te VM mai i te paataka raraunga hypervisor, ka mahia he raupapa arowhai qcow ki te ahua kōpae VM, a, i te otinga angitu, ka hanga he konae whirihoranga xml mo te VM hou me te ahua kōpae "honohono clone" o te hou. VM. Muri iho ka utaina te whirihora xml o te VM hou ki roto i te paataka korero hypervisor ka whakarewahia te VM. Ka nukuhia te tauranga "spice_console" mai i recycle.list ki clear.list. Ka mutu te mahi a vm_create.sh ka mutu te mahi a vm_manager.sh.
Ka hono atu koe, ka timata nga mea katoa mai i te timatanga.

Mo nga ohorere, kei roto i te kete te vm_clear.sh hōtuhi, e rere kaha ana i roto i nga VM katoa mai i te poka wai ka mukua, ka tautuhi i nga uara rarangi ki te kore. Ma te karanga i te wa o te wa o te whawhai ka taea e koe te tiimata (i raro i) VDI me te papa ma.

Na tenei e hiahia ana ahau ki te whakaoti i te wahanga tuatahi o taku korero. Ko nga mea i runga ake nei me nui mo nga kaiwhakahaere punaha ki te whakamatau i raro i te VDI i te mahi. Mena ka kitea e te hapori he kaupapa pai tenei, i te waahanga tuarua ka korero ahau mo te whakarereke i te Fedora livecd me te huri hei kiosk.
