Kunyangwe panguva yenjodzi pane nguva dzose yekapu yetii
DRP (hurongwa hwekudzoreredza njodzi) chinhu chisingazombodikanwa. Asi kana mabheya akangoerekana atama panguva yemwaka wekusangana akatsenga nemusana wefiber optical kana junior admin akadonhedza hwaro hunobereka, iwe zvechokwadi unoda kuve nechokwadi chekuti uchave ne pre-yakagadzirirwa chirongwa chezvekuita nekunyadzisa uku.
Nepo vatengi vachivhunduka vachitanga kutema mafoni ekutsigira tekinoroji, junior ari kutsvaga cyanide, unovhura hamvuropu tsvuku zvine hungwaru uye wotanga kuisa zvese zvakarongeka.
Mune ino positi ini ndinoda kugovera mazano ekunyora DRP uye zvazvinofanira kuve nazvo. Tichatarisa zvakare zvinhu zvinotevera:
- Dzidza kufunga semunhu akaipa.
- Ngatitarisei zvakanakira kapu yetii panguva yeapocalypse.
- Ngatifungei nezve yakanakira DRP chimiro
- Ngationei kuti tingaiedza sei
Ndeapi makambani angave anobatsira?
Zvakaoma kwazvo kudhirowa mutsetse kana iyo IT department inotanga kuda zvinhu zvakadaro. Ndingati iwe zvechokwadi unoda DRP kana:
- Kumisa sevha, kushandisa kana kurasikirwa neimwe dhatabhesi kunotungamira mukurasikirwa kukuru kwebhizinesi rese.
- Iwe une yakazara-yakazara IT department. Mupfungwa yedhipatimendi muchimiro chechikamu chakazara chekambani, ine bhajeti rayo, uye kwete vashoma vakaneta vashandi vanoisa network, kuchenesa mavhairasi uye kuzadzazve maprinta.
- Iwe une bhajeti inogoneka yeinenge chikamu chedundancy kana pane emergency.
Kana iyo IT department yanga ichipemha kwemwedzi ingangoita akati wandei maHDD mune yekare sevha ye backups, haungaite kuti ukwanise kuronga mafambiro akazara ebasa rakakundikana kuchengetedza huwandu. Kunyangwe pano zvinyorwa hazvizove zvakanyanya.
Zvinyorwa zvakakosha
Tanga nezvinyorwa. Ngatitii sevhisi yako inomhanya pane Perl script yakanyorwa zvizvarwa zvitatu zvakapfuura nema admins, asi hapana anoziva kuti inoshanda sei. Chikwereti chehunyanzvi chakaunganidzwa uye kushaikwa kwezvinyorwa zvinokupfura iwe kwete chete mumabvi, asiwo mune mamwe mitezo, inyaya yenguva.
Kana wangove netsananguro yakanaka yezvikamu zvesevhisi, tsvaga nhamba dzetsaona. Ivo vanenge vachinyatso fananidzira. Semuenzaniso, diski yako inozara nguva nenguva, izvo zvinoita kuti node ikundikane kusvika yacheneswa nemaoko. Kana kuti sevhisi yemutengi inotadza kuwanikwa nekuda kwekuti mumwe munhu akanganwa kuvandudza chitupa, uye Let's Encrypt haina kukwanisa kana kusada kugadzirisa.
Pfungwa semuparadzi
Chikamu chakaoma kwazvo ndechekufanotaura tsaona dzisina kumboitika, asi dzinogona kukanganisa sevhisi yako zvachose. Kuno ini nevandinoshanda navo tinowanzotamba nhubu. Tora kofi yakawanda uye chimwe chinhu chinonaka uye uzvivhare muimba yemusangano. Ingoita shuwa kuti munhaurirano dzakafanana iwe unokiya mune iwo mainjiniya ivo pachavo vakagadzira iyo chinangwa sevhisi kana kugara vachishanda nayo. Zvadaro, pabhodhi kana pabepa, unotanga kudhirowa zvose zvinotyisa zvinogona kuitika kubasa rako. Izvo hazvifanirwe kuenda kune zvakadzama pasi kune yakasarudzika mukadzi wekuchenesa uye kudhonza tambo; zvakakwana kufunga nezve "Kutyora kwekuvimbika kwetiweki yenzvimbo."
Kazhinji, mamiriro echimbichimbi mazhinji anowira mumhando dzinotevera:
- Network kukundikana
- OS masevhisi kutadza
- Kukundikana kwekushandisa
- Kukundikana kwesimbi
- Virtualization kukundikana
Ingopfuura nemhando yega yega uye uone zvinoenderana nebasa rako. Semuenzaniso, iyo Nginx daemon inogona kudonha uye kusasimuka - izvi zvinoreva kutadza pachikamu cheOS. Mamiriro asina kujairika anoita kuti webhu application yako ikunde iko kutadza kwesoftware. Paunenge uchishanda kuburikidza nedanho iri, zvakakosha kugadzirisa kuongororwa kwedambudziko. Maitiro ekusiyanisa chimiro chechando pane virtualization kubva kudonha cis drive uye kutadza kwetiweki, semuenzaniso. Izvi zvakakosha kukurumidza kutsvaga avo vane mhosva uye kutanga kudhonza muswe wavo kusvikira njodzi yagadziriswa.
Mushure mekunge matambudziko akanyorwa pasi, tinodurura kofi yakawanda uye tinotanga kufunga nezvezvisinganzwisisike, apo mamwe maparamita anotanga kuenda kure kupfuura zvakajairwa. Semuyenzaniso:
- Chii chinoitika kana nguva iri pane inoshanda node ikadzokera kumashure kweminiti kune mamwe ari musumbu?
- Uye kana nguva ichienda mberi, uye kana nemakore gumi?
- Chii chinoitika kana cluster node ikangoerekana yarasikirwa netiweki yayo panguva yekuyananisa?
- Chii chichaitika kana node mbiri dzisingagovani hutungamiriri nekuda kwekuzviparadzanisa nevamwe kwekanguva pane network?
Panguva ino, nzira yekudzokera kumashure inobatsira zvikuru. Iwe unotora nhengo yakasindimara yechikwata ine fungidziro inorwara uye ugomupa basa rekuronga kuparadza munguva pfupi pfupi inogoneka iyo inoburitsa iyo sevhisi. Kana zvakaoma kuongorora, kunyange nani. Iwe haungatendi izvo zvisinganzwisisike uye zvinotonhorera mazano mainjiniya anouya nazvo kana iwe ukavapa zano rekutyora chimwe chinhu. Uye kana ukavavimbisa bhenji rekuyedza izvi, zvakanaka.
Chii DRP yako iyi?!
Saka iwe wakatsanangura yako yekutyisidzira modhi. Vakafungawo vagari veko vakacheka tambo dzefiber optic vachitsvaga mhangura, uye radar yemauto inodonhedza tambo yeredhiyo chaiyo neChishanu na16:46. Zvino tinofanira kunzwisisa zvokuita zvose izvi.
Basa rako nderekunyora iwo mahamvuropu matsvuku chaiwo anozovhurwa nenjodzi. Pakarepo tarisira kuti kana (kwete kana!) Zvose zvinosvika pakuguma, chete mudzidzi asina ruzivo rwakanyanya anenge ari pedyo, ane maoko achange achizununguka nechisimba kubva kutyisa kwezviri kuitika. Ona kuti zviratidzo zvekukurumidzira zvinoitwa sei mumahofisi ekurapa. Somuenzaniso, chii chaunofanira kuita kana anaphylactic shock. Vashandi vekurapa vanoziva maprotocol ese nemoyo, asi kana munhu ari pedyo atanga kufa, kazhinji munhu wese anenge akabatirira pachinhu chiri kuona. Kuti uite izvi, pane mirairo yakajeka pamadziro nezvinhu zvakaita se "vhura pasuru yezvakadaro" uye "kupa mayunitsi akawanda emushonga netsinga."
Zvakaoma kufunga munjodzi! Panofanira kuve nemirairo iri nyore ye spinal cord parsing.
DRP yakanaka ine akati wandei akareruka mabhuroko:
- Ndiani wekuzivisa nezvekutanga kwetsaona. Izvi zvakakosha kuitira kuenzanisa nzira yekubvisa zvakanyanya sezvinobvira.
- Maitiro ekuongorora nemazvo - ita trace, tarisa mu systemctl mamiriro servicename uye zvichingodaro.
- Inguva yakawanda sei yaungapedza padanho rega rega? Kana iwe usina nguva yekuigadzirisa nemaoko mukati meSLA nguva, iyo chaiyo muchina unourawa uye unotenderedzwa kumashure kubva nezuro backup.
- Ndoita sei kuti tsaona yapera.
Rangarira kuti DRP inotanga kana sevhisi yakundikana zvachose uye inopera kana sevhisi yadzoserwa, kunyangwe nekuderera kwekuita. Kungorasikirwa nekuchengetera hakufanire kukonzeresa DRP. Iwe unogona zvakare kunyora kapu yetii muDRP. Serious. Maererano nenhamba, njodzi dzakawanda dzinoshanduka kubva pakusingafadzi kuenda kunjodzi nekuda kwekuti vashandi mukuvhunduka vanomhanyira kugadzirisa chimwe chinhu, panguva imwe chete vachiuraya iyo chete mhenyu node ine data kana pakupedzisira kupedza sumbu. Sezvo mutemo, maminetsi mashanu nekapu yetii achakupa imwe nguva yekudzikama uye kuongorora zviri kuitika.
Usavhiringe DRP uye system pasipoti! Usazviremedze nedata risingakoshi. Ingoita kuti zvikwanise kukurumidza uye zviri nyore kushandisa hyperlink kuenda kune yaunoda chikamu chezvinyorwa uye uverenge mune yakawedzera fomati nezve inodiwa zvikamu zvebasa rekuvaka. Uye muDRP pachayo pane chete mirairo yakananga yekuti kupi uye sei kubatana nemirairo chaiyo yekukopa-namira.
Nzira yekuedza nemazvo
Ita shuwa kuti chero mushandi ane mutoro anokwanisa kupedzisa zvinhu zvese. Panguva inonyanya kukosha, zvinogona kuitika kuti injiniya haana kodzero yekuwana iyo inodiwa sisitimu, hapana mapassword eakaundi inodiwa, kana kuti haazive kuti chii "Batanidza kune service management console kuburikidza neproxy pa head officeβ zvinoreva. Pfungwa imwe neimwe inofanira kuva yakapfava zvakanyanya.
Pakaipa - "Enda kune virtualization uye tangazve iyo yakafa node"
Zvakarurama - "Batanidza kuburikidza newebhu interface kune virt.example.com, muchikamu chenodhi, tangazve node iri kukonzera kukanganisa."
Dzivisa kusanzwisisika. Rangarira mudzidzi anotya.
Iva nechokwadi chekuedza DRP. Ichi hachisi chirongwa chekuratidzira - chimwe chinhu chinokutendera iwe nevatengi vako kukurumidza kubuda mumamiriro ezvinhu akaoma. Zvakanakisisa kuita izvi kakawanda:
- Imwe nyanzvi uye vadzidzi vakati wandei vanoshanda pabhenji rekuyedza rinotevedzera sevhisi chaiyo sezvinobvira. Iyo nyanzvi inopwanya sevhisi nenzira dzakasiyana uye inoita kuti vadzidzi vadzorere zvinoenderana neDRP. Matambudziko ese, zvinyorwa zvisinganzwisisiki uye zvikanganiso zvinorekodhwa. Mushure mekunge vadzidzisi vadzidziswa, iyo DRP inowedzerwa uye inorerutswa munzvimbo dzisina kujeka.
- Kuedza pabasa chairo. Muchokwadi, haugone kugadzira kopi yakakwana yebasa chairo. Naizvozvo, kakati wandei pagore zvinodikanwa kuti ugare uchidzima mamwe maseva, kupatsanura kubatanidza uye kukonzera dzimwe njodzi kubva pane rondedzero yekutyisidzira kuti uongorore maitiro ekudzoreredza. Kukundikana kwakarongwa kwemaminetsi gumi pakati pehusiku kuri nani pane kutadza kamwe kamwe kwemaawa akati wandei panguva yekuremerwa kwepamusoro nekurasikirwa nedata.
- Real troubleshooting. Hongu, ichi zvakare chikamu chekuyedzwa. Kana tsaona ikaitika iyo yanga isiri pane rondedzero yekutyisidzira, zvinodikanwa kuwedzera uye kupedzisa iyo DRP zvichienderana nemhedzisiro yekuferefeta kwayo.
Pfungwa huru
- Kana shit ichigona kuitika, haingoitike chete, asi ichaita saizvozvo munjodzi yakaipisisa inogoneka.
- Ita shuwa kuti une zviwanikwa zvekutakura mutoro wekukurumidzira.
- Ita shuwa kuti une ma backups, anogadzirwa otomatiki uye anogara achitariswa kuti anoenderana here.
- Funga kuburikidza nezvinowanzoitika zvekutyisidzira.
- Ipa mainjiniya mukana wekuuya neasiri-standard sarudzo dzekuendesa sevhisi.
- DRP inofanira kunge iri nyore uye yakapusa kuraira. Yese yakaoma diagnostics inoitwa chete mushure mekunge sevhisi yevatengi yadzorerwa. Kunyange kana iri reserve capacity.
- Ipa nhamba dzenhare dzakakosha uye mameta muDRP.
- Gara uchiyedza vashandi veDRP kunzwisisa.
- Ronga tsaona dzakarongwa panzvimbo dzekugadzira. Mastand haagone kutsiva zvese.
