Kukonzekera DRP - musaiwale kuganizira meteorite

Ngakhale pakagwa tsoka nthawi zonse pamakhala nthawi ya tiyi

DRP (ndondomeko yobwezeretsa masoka) ndi chinthu chomwe sichidzafunikanso. Koma ngati nkhwawa zimasamuka mwadzidzidzi nthawi yokwerera zidzudzula msana kapena woyang'anira wamkulu agwetsa maziko abwino, mufuna kutsimikiza kuti mudzakhala ndi dongosolo lokonzekeratu zochita ndi manyazi onsewa.

Pamene makasitomala ali ndi mantha amayamba kudula mafoni othandizira luso, wamng'ono akufunafuna cyanide, mwanzeru mutsegula envelopu yofiira ndikuyamba kuyika zonse bwino.

Mu positi iyi ndikufuna kugawana malingaliro amomwe mungalembe DRP ndi zomwe ziyenera kukhala. Tiwonanso zinthu zotsatirazi:

1. Tiyeni tiphunzire kuganiza ngati munthu woipa.
2. Tiyeni tione ubwino wa kapu ya tiyi pa nthawi ya apocalypse.
3. Tiyeni tiganizire za dongosolo losavuta la DRP
4. Tiyeni tiwone momwe tingayesere

Ndi makampani ati omwe angakhale othandiza?

Ndizovuta kwambiri kujambula mzere pamene dipatimenti ya IT iyamba kufuna zinthu zotere. Ndinganene kuti mukufunadi DRP ngati:

• Kuyimitsa seva, kugwiritsa ntchito kapena kutaya deta kumabweretsa kuwonongeka kwakukulu kwa bizinesi yonse.
• Muli ndi dipatimenti yokwanira ya IT. M'lingaliro la dipatimenti mu mawonekedwe a wathunthu wagawo wa kampani, ndi bajeti yake, osati ochepa antchito kutopa atagona maukonde, kuyeretsa mavairasi ndi refilling osindikiza.
• Muli ndi bajeti yokwanira yoti muchotsedwe pang'ono pakagwa mwadzidzidzi.

Pamene dipatimenti ya IT yakhala ikupempha kwa miyezi ingapo kwa ma HDD angapo mu seva yakale yosungiramo zosunga zobwezeretsera, simungathe kukonzekera kusuntha kwathunthu kwa ntchito yolephera kusunga mphamvu. Ngakhale pano zolembedwa sizikhala zochulukirapo.

Zolemba ndizofunikira

Yambani ndi zolemba. Tinene kuti ntchito yanu imayenda pa Perl script yomwe idalembedwa mibadwo itatu yapitayo ndi ma admins, koma palibe amene akudziwa momwe imagwirira ntchito. Ngongole yaukadaulo yosonkhanitsidwa ndi kusowa kwa zolemba mosakayikira zidzakuwomberani osati pa bondo lokha, komanso m'miyendo ina, ndi nkhani ya nthawi.

Mukakhala ndi kufotokoza kwabwino kwa zigawo zautumiki, yang'anani ziwerengero za ngozi. Iwo adzakhala pafupifupi kwathunthu mmene. Mwachitsanzo, disk yanu imakhala yodzaza nthawi ndi nthawi, zomwe zimapangitsa kuti node isalephereke mpaka itatsukidwa pamanja. Kapena ntchito yamakasitomala imakhala yosapezeka chifukwa choti wina wayiwalanso kukonzanso satifiketi, ndipo Let's Encrypt sanathe kapena kukana kukonza.

Maganizo ngati wowononga

Chovuta kwambiri ndikulosera za ngozi zomwe sizinachitikepo, koma zomwe zitha kusokoneza ntchito yanu kwathunthu. Kuno ine ndi anzanga nthawi zambiri timasewera anthu oipa. Tengani khofi wambiri ndi chinachake chokoma ndikudzitsekera m'chipinda chochitira misonkhano. Ingowonetsetsani kuti pazokambirana zomwezo mumatsekera mainjiniya omwe adapanga zomwe akufuna kapena amagwira nawo ntchito pafupipafupi. Kenako, pa bolodi kapena papepala, mumayamba kujambula zoopsa zonse zomwe zingachitike pautumiki wanu. Sikofunikira kufotokozera mwatsatanetsatane kwa mayi wina woyeretsa ndikutulutsa zingwe; ndikokwanira kulingalira za "Kuphwanya kukhulupirika kwa netiweki yakomweko."

Nthawi zambiri, zochitika zadzidzidzi zambiri zimagwera m'mitundu iyi:

• Kulephera kwa netiweki
• Kulephera kwa ntchito ya OS
• Kulephera kugwiritsa ntchito
• Kulephera kwachitsulo
• Kulephera kwa Virtualization

Ingodutsani pazowonera zilizonse ndikuwona zomwe zikugwirizana ndi ntchito yanu. Mwachitsanzo, daemon ya Nginx ikhoza kugwa osadzuka - uku ndikulephera kwa OS. Chosowa chomwe chimapangitsa kuti pulogalamu yanu yapaintaneti ilephereke ndikulephera kwa mapulogalamu. Pachiyambi cha siteji iyi, ndikofunika kupeza matenda a vutoli. Momwe mungasiyanitsire mawonekedwe achisanu pa virtualization kuchokera pagalimoto yakugwa ya cis ndi kulephera kwa netiweki, mwachitsanzo. Izi ndizofunikira kuti mupeze mwamsanga omwe ali ndi udindo ndikuyamba kukoka mchira mpaka ngoziyo itathetsedwa.

Pambuyo pa zovuta zomwe zalembedwa, timathira khofi wochulukirapo ndikuyamba kuganizira zachilendo kwambiri, pomwe magawo ena amayamba kupita mopitilira muyeso. Mwachitsanzo:

• Kodi chimachitika ndi chiyani ngati nthawi yomwe ili pamfundo yogwira ibwerera mmbuyo kwa mphindi imodzi ndi ena omwe ali mgululi?
• Nanga bwanji ngati nthawi ikupita patsogolo, bwanji ngati ndi zaka 10?
• Kodi chimachitika ndi chiyani ngati nodi yamagulu itayika mwadzidzidzi maukonde ake pakulumikizana?
• Kodi chingachitike ndi chiyani ngati ma node awiri sagawana utsogoleri chifukwa chodzipatula kwakanthawi pa intaneti?

Panthawi imeneyi, njira yosinthira ndiyothandiza kwambiri. Mumatenga membala wamakani kwambiri m'gululi ndi malingaliro odwala ndikumupatsa ntchito yokonza zowononga munthawi yochepa kwambiri yomwe ingagwetse ntchitoyo. Ngati kuli kovuta kuzindikira, ngakhale bwino. Simungakhulupirire malingaliro odabwitsa komanso abwino omwe akatswiri amabwera nawo ngati mutawapatsa lingaliro kuti athyole china chake. Ndipo ngati muwalonjeza benchi yoyesera pa izi, zili bwino.

Kodi DRP yanu ndi chiyani?!

Chifukwa chake mwafotokozera mtundu wanu wowopseza. Adaganiziranso anthu akumaloko omwe amadula zingwe za fiber optic pofunafuna mkuwa, komanso radar yankhondo yomwe imatsitsa chingwe cholumikizira wailesi Lachisanu nthawi ya 16:46. Tsopano tiyenera kumvetsetsa chochita ndi zonsezi.

Ntchito yanu ndi kulemba maenvulopu ofiira kwambiri omwe adzatsegulidwa mwadzidzidzi. Nthawi yomweyo yembekezerani kuti pamene (osati ngati!) Chilichonse chifika kumapeto, wophunzira yekhayo yemwe sakudziwa zambiri adzakhala pafupi, omwe manja ake adzagwedezeka mwamphamvu chifukwa cha mantha a zomwe zikuchitika. Onani momwe zizindikiro zadzidzidzi zimagwiritsidwira ntchito m'maofesi azachipatala. Mwachitsanzo, chochita ndi anaphylactic mantha. Ogwira ntchito zachipatala amadziwa ndondomeko zonse pamtima, koma munthu wapafupi akayamba kufa, nthawi zambiri aliyense amangogwira chilichonse chomwe akuwona. Kuti muchite izi, pali malangizo omveka bwino pakhoma okhala ndi zinthu monga "tsegulani phukusi la izi ndi zina" komanso "perekani mayunitsi ambiri a mankhwalawa kudzera m'mitsempha."

Ndizovuta kuganiza pakagwa mwadzidzidzi! Payenera kukhala malangizo osavuta odulira msana.

DRP yabwino imakhala ndi midadada ingapo yosavuta:

1. Oyenera kumudziwitsa za kuyamba kwa ngozi. Izi ndizofunikira kuti mufanane ndi njira yochotsera momwe mungathere.
2. Momwe mungadziwire molondola - fufuzani, yang'anani mu systemctl status servicename ndi zina zotero.
3. Kodi mungawononge nthawi yochuluka bwanji pagawo lililonse? Ngati mulibe nthawi yokonza pamanja mkati mwa nthawi ya SLA, makina enieni amaphedwa ndikubwezeredwa kuchokera ku zosunga zobwezeretsera dzulo.
4. Momwe mungatsimikizire kuti kuwonongeka kwatha.

Kumbukirani kuti DRP imayamba pomwe ntchitoyo yalephera kwathunthu ndikutha ntchitoyo ikabwezeretsedwa, ngakhale ndi kuchepa kwachangu. Kungotaya kusungitsa sikuyenera kuyambitsa DRP. Mukhozanso kulemba kapu ya tiyi mu DRP. Mozama. Malingana ndi ziwerengero, ngozi zambiri zimatembenuka kuchoka ku zosasangalatsa kupita ku zoopsa chifukwa chakuti ogwira ntchito ali ndi mantha amathamangira kukonza chinachake, nthawi imodzi kupha mfundo yamoyo yokhayo ndi deta kapena potsiriza kumaliza masango. Monga lamulo, mphindi 5 ndi kapu ya tiyi zidzakupatsani nthawi yoti mukhazikike mtima pansi ndikusanthula zomwe zikuchitika.

Osasokoneza DRP ndi pasipoti yadongosolo! Osamuchulutsa ndi data yosafunikira. Ingopangitsani kuti mugwiritse ntchito ma hyperlink mwachangu komanso mosavuta kupita kugawo lomwe mukufuna lazolemba ndikuwerenga mumtundu wokulitsidwa za magawo ofunikira a zomangamanga. Ndipo mu DRP palokha muli malangizo achindunji okha ndi momwe mungalumikizire ndi malamulo enieni a copy-paste.

Momwe mungayesere molondola

Onetsetsani kuti wogwira ntchito aliyense wodalirika amatha kumaliza zinthu zonse. Panthawi yovuta kwambiri, zitha kukhala kuti injiniya alibe ufulu wopeza makina ofunikira, palibe mawu achinsinsi a akaunti yofunikira, kapena sadziwa zomwe "Lumikizani ku console yoyang'anira ntchito kudzera pa proxy pa head office” amatanthauza. Mfundo iliyonse ikhale yophweka kwambiri.

zolakwika - "Pitani ku virtualization ndikuyambitsanso node yakufa"
molondola - "Lumikizani kudzera pa intaneti ku virt.example.com, mu gawo la nodi, yambitsaninso mfundo yomwe ikuyambitsa cholakwikacho."

Pewani kufotokoza momveka bwino. Kumbukirani wophunzira wamanthayo.

Onetsetsani kuti mwayesa DRP. Ili si dongosolo chabe lawonetsero - ndichinthu chomwe chingakuthandizeni inu ndi makasitomala anu kuti mutuluke mumkhalidwe wovuta. Ndi bwino kuchita izi kangapo:

• Katswiri m'modzi ndi ophunzira angapo amagwira ntchito pa benchi yoyesera yomwe imatengera ntchito yeniyeni momwe angathere. Katswiriyo amathyola ntchitoyo m'njira zosiyanasiyana ndikupangitsa ophunzira kuti abwezeretsenso malinga ndi DRP. Mavuto onse, zolembedwa zosamveka ndi zolakwika zimalembedwa. Ophunzira akaphunzitsidwa, DRP imakulitsidwa ndikusinthidwa m'malo osadziwika bwino.
• Kuyesa pa ntchito yeniyeni. M'malo mwake, simungathe kupanga kope langwiro la ntchito yeniyeni. Chifukwa chake, kangapo pachaka ndikofunikira kuzimitsa ma seva ena, kudula maulumikizidwe ndikuyambitsa masoka ena pamndandanda wazowopseza kuti awone dongosolo lobwezeretsa. Kulephera kokonzekera kwa mphindi 10 pakati pausiku kuli bwino kusiyana ndi kulephera mwadzidzidzi kwa maola angapo panthawi yochuluka kwambiri ndi kutayika kwa deta.
• Kuthetsa kwenikweni ngozi. Inde, ichinso ndi gawo la kuyesa. Ngati ngozi ikuchitika yomwe sinali pa mndandanda wa zoopseza, m'pofunika kuwonjezera ndi kutsiriza DRP potengera zotsatira za kafukufuku wake.

Mfundo Zofunika

1. Ngati zoyipa zitha kuchitika, sizingochitika zokha, koma zitha kuchitika m'malo ovuta kwambiri.
2. Onetsetsani kuti muli ndi zida za failover.
3. Onetsetsani kuti muli ndi zosunga zobwezeretsera, zimangopangidwa zokha ndipo zimafufuzidwa pafupipafupi.
4. Ganizirani zochitika zowopsa.
5. Perekani mainjiniya mwayi woti abwere ndi zosankha zomwe sizili zoyenera kuti apereke ntchitoyo.
6. DRP iyenera kukhala malangizo osavuta komanso osamveka. Onse diagnostics zovuta ikuchitika pokhapokha utumiki kasitomala 'wabwezeretsedwa. Ngakhale pa reserve capacity.
7. Perekani manambala ofunikira a foni ndi olumikizana nawo mu DRP.
8. Yesani kumvetsetsa kwa ogwira ntchito pa DRP pafupipafupi.
9. Konzani ngozi zomwe zakonzedwa pamalo opangira. Zoyimira sizingalowe m'malo mwa chilichonse.
