Kare kare, ndakaona mumwe munhu muboka achitengesa VPS ne9.9 yuan pagore. Yaiva muripo wegore negore, wakanyorwa kuti 2 cores ne4G, uye mutengo wacho waive wakachipa kagumi pane makambani makuru iwayo.

Ndakaisa odha yacho ndisingafungiri.

Shamwari, ungazvitenda here? Kana izvi zvatanga, zvinotora masekondi maviri kuti ndinyore murairo, uye pandinobatana neSSH, cursor inotenderera kwenguva refu usati waona mhinduro yacho.

Ndakashamisika.

Magadzirirwo aya haana kunaka. Kunyangwe kana magadzirirwo e dual-core 4G akaipa, haafanire kunge ari ekunonoka kudaro.

Ndiri kutanga kufunga kuti muchina uyu ungangodaro wakatengeswa zvakanyanya.

Mushure mekutsvaga-tsvaga, ndakaona kuti ndizvo zvazviri zvechokwadi. Kuti vaparadzire mutengo we physical server, VPS providers vachashandisa ma virtual machines akawanda kana kutoti mazana akawanda pamuchina mumwe chete, vese vachigovana CPU, memory ne hard drive.

Wakashambadza system yakatsaurirwa ye dual-core, asi kuti ma cores mangani aunowana zvinoenderana nekuti vavakidzani vako vari pamuchina mumwe chete vane simba rakadii.

Mubvunzo unomuka ndewekuti: vanhu vangani vakazadza muchina wangu, uye zvinoita here kuti ndizive?

Muchinyorwa chino, ndichatsanangura nyaya iyi zvakadzama uye ndichaikurukura zvakadzama.

Regai nditange ndatsanangura pfungwa inorwadza zvikuru, nekuti vanhu vazhinji vanowira mumusungo uyu wekufunga.

Chinhu chinodiwa chinofanira kunzwisiswa kutanga

VPS, Virtual Private Server, ndiyo mhinduro huru ikozvino, uye KVM full virtualization ndiyo inonyanya kushandiswa.

Chaizvoizvo igumbeze rawakagoverwa paserver hombe yemumwe munhu.

Chaunogona kutarisa ndechekuti vanhu vangani vari kupinda uye vari kushandisa cubicle yako parizvino.

Chausingakwanise kuziva ndechekuti mupi wekambani akavhura maVPS mangani pamuchina wekuchengetedza, zvichireva kuti vamwe vanoroja.

Sei ndisingakwanise kuiwana? Yakagadzirwa paindaneti uye yakaparadzaniswa.

Michina yepamhepo haimbosangani. Kana uri mumuchina wako wepamhepo, haugone kuona michina yepamhepo iri padivi pako, uye haugone kuona kuti muchina wepamhepo wakaita sei. Backend yemupi webasa chete ndiyo inogona kuona mufananidzo wese.

Saka chinonyanya kukosha chaunogona kuziva ndechewaunogara naye pamuchina uyu. Kana paine mimwe michina mingani iri pamuchina uyu, unogona kungofungidzira zvisina kunanga zvichibva pane zvimwe zviratidzo.

Rangarira chirevo ichi, uye uchavimba nacho kuti chikutungamirire pane zvimwe zvese.

Unogona kuverenga huwandu hwevanhu vari paVPS imwe chete, asi haugone kuverenga nemazvo kuti mangani maVPS ari pamuchina we physical host.

Vanhu vazhinji vanotenga rudzi urwu rwemuchina, uye munhu mumwe chete anobva angouya mupfungwa dzake.

Mumwe musikana achangobva kupedza kudzidza kubva muguta diki rechikamu chechina kana chechishanu, aine mari shoma muhomwe make, aida kugadzira blog rake kana kunyora script diki. Maziso ake akapenya paakaona mutengo we9.9 yuan.

Aisaziva kuti kutengesa zvakanyanya zvinorevei; aingoziva nezvemitengo yakaderera chete.

Kana sisitimu ikadonha, anongotuka muchina wacho semarara, asingafungi kuti mazana evanhu vari pedyo naye vari kukwikwidzana naye paCPU imwe chete.

Linux Ndinotarisa sei (SSH login)?

Ngatitangei neLinux inonyanya kushandiswa. Mushure mekunge mapinda neSSH...

Murairo wekutanga ndewokunyora 'w' wobva wadzvanya Enter.

Ichanyora vese vashandisi vapinda mukati mayo, kusanganisira zita rekushandisa, kero ye IP yavakabatana nayo, nguva yekupinda, uye murairo wepari zvino.

Nyatsoteerera kero ye IP iri mukoramu yeFROM.

Kana ukavhura mahwindo akawanda eSSH neakaundi imwe chete, icharatidza marekodhi akawanda. Izvi hazviverengerwi sevanhu vakawanda. Unofanira kutarisa kana maIP akasiyana. MaIP akasiyana anoratidza vashandisi vakasiyana.

Kuti uwane nzira pfupi, shandisa "ndiani" kuti uwane account yako nekero yeIP chete - yakachena uye iri nyore.

Kana ukaona kuverenga nemaoko kuchinetsa, ingoshandisa murairo wekudzvanya kamwe chete kuti uverenge huwandu hwema IP akasiyana.

w | awk 'NR>2 {print $3}' | sort -u | wc -l

Mutsetse uyu wakaoma; unobvisa ma IP ese epakutanga, unobvisa ma duplicate, uye pakupedzisira unokupa nhamba inoratidza kuti mangani ma IP akasiyana ari kubatanidza kumuchina uyu parizvino.

Kuwanda kwevanhu vari muimba imwe chete ndiko kwakawedzerawo vanhu vari kugara pamwe chete.

Kana uchida kuona kuti ndiani akapinda nekubuda, zvinyorwa zvekupedzisira zvekupinda nekubuda zvicharatidzwa, kusanganisira nguva chaiyo yavakabuda.

Imwe nzira ndeyekushandisa `cat /etc/passwd` kuti uone kuti ndeapi maakaundi emunharaunda akagadzirwa musystem.

Zvisinei, izvi ndezvemaakaundi ese, uye haasi ese anogona kunge ari online. Inogona kushandiswa chete sereferensi, kwete sevanhu vakawanda.

Maitiro ekutarisa (desktop iri kure) paWindows?

Kana iri Windows VPS, kana wangobatanidza uchishandisa remote desktop, vhura hwindo reCMD.

Kunyora `quser` kana `query user` kuchanyora zvikamu zvese zveRDP, zvichiratidza zvakajeka kuti ndiani akapinda, kuti chikamu chacho chakavharwa here kana kuti chakashanda, uye kuti vakapinda kwenguva yakareba sei.

Kana usingade kunyora mirairo, unogona kuchinja kuenda kuUsers tab muTask Manager kuti uwane graphical interface inoratidza kuti ndiani ari online nekukurumidza.

Windows iri nyore kushandisa kupfuura Linux; pane murairo mumwe chete, uye graphical interface inowanikwa zviri nyore.

Fungidzira kana muchina wemubati weimba wakanyanya kutengeswa nezviratidzo izvi

Kuongorora kuri pamusoro apa kunosanganisira kuona kuti vangani vari paVPS imwe chete.

Asi sezvandambotaura, handizvo zvinonyanya kukosha. Nyaya inonyanya kukosha ndeyekuti mupi wezvirongwa akavhura mamwe maVPS akawanda here pamuchina wekugamuchira, achikwikwidzana newe kuti uwane zviwanikwa.

Haugone kuzviverenga zvakananga; unogona kungotarisa zviratidzo chete.

Linux ine chiyero chakajeka chinonzi CPU steal time, chiri %st mumurairo wepamusoro.

Nyora `top`, tarisa mutsetse weCPU, uye uchaona `st` pakupera.

st≈0 zvinoreva kuti hapana vavakidzani vanokwikwidza CPU yako, uye uri kunakidzwa nayo zviri nyore wega.

Kana st ichigara ichidarika 5%, saka pane mukana mukuru wekuti imwe VPS iri kushandisa zviwanikwa zveCPU pamuchina wako wekutambira, uye simba rako rekombiyuta riri kubiwa iwe usingatombozvioni.

Kana usinganzwe wakasununguka kungotarisa pairi, shandisa vmstat 1 kuti urambe wakatarira pakoramu ye st. Uchaona vavakidzani vako vachifamba ipapo ipapo.

vmstat 1

Kunyange hazvo vatengesi veVPS vachinyora zviwanikwa zvezviwanikwa, vamwe vanozvitengesa zvakanyanya, vachichengeta michina yakawanda yevamwe vatengesi pamuchina wehost. Kana zviwanikwa zvikasava zvishoma, system yako inotanga kunonoka.

st ndiye munhu anonyatsopa ruzivo rwakatendeseka.

Nzvimbo yekurangarira nedhisiki inoratidzawo tsika isina kunaka yekutengesa zvakanyanya.

Kana zvasvika kune zviwanikwa, kune nzvimbo mbiri dziri nyore kuvanza manomano: memory nedisk.

Kutanga, regai ndiise mvura inotonhora pane izvi: haugone kuverenga memory chaiyo yasara nehard drive yemuchina wehost kubva mukati memuchina chaiwo; unogona kungozvisimbisa pamuchina wako wobva waita fungidziro dzisina kunanga.

Kutengesa zvakanyanya kwevatengesi kunoitika padanho remuchina wekugamuchira vatengi. Chaunogona kusimbisa pamuchina wako ndechekuti chikamu chako chawakapihwa chaderedzwa here, uye, zvichibva pane zvawakaona, kana mumwe munhu ari kukwikwidza newe pachinhu ichocho.

Kutanga, verenga huwandu hwezvinhu zviri mundangariro.

Shandisa `free -h` kuti utarise mutsetse we`total`. Enzanisa nenhamba yakashambadzwa nemutengesi. Nhamba yacho idiki zvakanyanya, zvinoreva kuti quota yaderedzwa. Vanoshambadza 4G asi vanongokupa 2G chete. Vanhu vazhinji vanowira mumusungo uyu.

Wobva watarisa pamakwikwi.

Kana mutoro wakaderera, shandisa vmstat 1 wotarisa pa si uye so columns. si inoshandiswa pakuchinjana uye saka inoshandiswa pakuchinjana.

Kana bhizinesi rako risiri pasi pekumanikidzwa kwakanyanya, asi si uye zvichingodaro zvichipfuura 0, saka zvingangoita kuti muchina wehost upererwe nememory, mutengesi atengesa muchina zvakanyanya, uye system yacho inomanikidzwa kuchinja memory yako kuenda kudhisiki, saka muchina wacho unononoka zvikuru.

Ziva kuti hazvishamisi kushandisa swap kana zvinhu zvakajairika, asi kuchinjana kakawanda kana zvinhu zvakawandisa idambudziko guru.

Izvi zvinoshandawo kumadhisiki.

Shandisa `df -h` kuti utarise saizi yemudzi wechikamu `/`. Enzanisa nechikamu chakatarwa; kana mutsauko wacho wakakura zvakanyanya, chikamu chacho hachina kukwana.

df -h

Kukakavadzana kweIO kuri nyore kuona ne `iostat -x 1`, uye unogona zvakare kutarisa `aw ai t` uye `%util`.

Kana usingaite mabasa ekuverenga kana kunyora, asi await inogara ichidarika mamirisekonzi makumi maviri, kana kuti %util yakamira pa100% kwenguva yakareba, zvingangoita kuti imwe VPS pamuchina wako wekugamuchira iri kuita mabasa ekuverenga nekunyora zvakanyanya, ichitora disk yako I/O. Iyi inyaya yakajairika yekutengesa zvakanyanya disk uye kukakavadzana.

Rangarira izvi mumutsara mumwe chete

Saka, tsanangura zvakajeka mumutsara mumwe chete.

MuVPS, vanhu vakawanda vanogovana login. PaLinux, shandisa murairo we 'w'; paWindows, shandisa murairo we 'quser'. Huwandu hwevashandisi vakasiyana hunotsanangurwa nema IP akasiyana.

Haumbofi wakawana nhamba chaiyo yeVPS dziri kushanda paserver yako chaiyo pamuchina wako; unogona kungofungidzira zvichibva pane zviratidzo zvakaita se st, swap, uye await.

Ngatidzokerei kumuchina we9.9 yuan kubva pakutanga.

Pandakazotarisa top gare gare, ndakaona kuti st yaive ichitenderera pa8% kwemakore, uye si yaiwanzoonekwa muvmstat.

Saka, zvinozoitika kuti handigari ndega; ndinogovana imba imwe chete nevavakidzani vakawanda, uye handitombokwanisi kuwana imba yekugezera zuva nezuva.

Izvi ndizvo zvakafanana nekushandisa mari yakawanda pakufamba nendege.

Matikiti endege anogara achitengesa matikiti akawanda ne20% kupfuura avanoda, vachibhejera kuti mumwe munhu acharasikirwa nendege yavo.

Vanopa VPS vanotengesa zvakanyanya nekubheja kuti vamwe vanhu vachatenga asi vasingazoshandisi kana kungoishandisa zvishoma, kuitira kuti kushandiswa kwepamusoro-soro kwemunhu wese kuwedzere uye pasave nematambudziko.

Kana ukahwina bheti, hapana chaunonzwa; kana ukakundwa, unenge uchitamba mitambo pakati pehusiku uye uchisangana nematambudziko anokuita kuti ubvunze kuti uripo here.

Hakuna chinhu chakadai sekudya kwemasikati kwemahara. Seri kwemubhadharo wepagore we9.9 yuan kune mumwe munhu ari kutakura mutoro wekuzara uku nekuda kwako.

Paunenge uchitenga VPS mune ramangwana, usangotarisa mutengo uye runyorwa rwemagadzirirwo.

Kutanga, nyora mirairo mishoma mushure mekuvhura komputa kuti uone kuti vanhu vangani vari mukamuri mako.

Kana pekugara pari padiki kana kuti kwete zvine simba guru pane zvaungafunga.

Hazvimbokuvadzi kuziva nezvekusawirirana kwemashoko.
