Momwe mungathetsere kuchuluka kwa VPS? Njira yokhathamiritsa magwiridwe antchito + kalozera wathunthu pakukulitsa kukumbukira kwa CPU

Kodi VPS yanu yadzaza ndipo yatsala pang'ono kugwa?

Kuyambira ndi kasinthidwe ka 4-core 16GB, nkhaniyi ikuwunikira mwatsatanetsatane momwe mungasankhire kuchuluka koyenera kwa ma CPU cores ndi kukumbukira, ndikupereka chitsogozo chokwanira pakuwongolera magwiridwe antchito a VPS.

Kaya ndikukhathamiritsa kwa database, kusintha kwa pulogalamu ya PHP kapena kukweza kwa Hardware, tili ndi malingaliro enieni okuthandizani kuti mupeze yankho labwino kwambiri kuti VPS yanu iziyenda mwachangu komanso mokhazikika, ndikutsazikana ndi zovuta!

Ndikukhulupirira kuti izi zingakuthandizeni, kuti VPS yanu isakhalenso yotanganidwa ngati kebab stall!

VPS yadzaza kwambiri.

Tangoganizani kuti VPS kasinthidwe CPU ndi 4 cores + 16GB kukumbukira, fufuzani top Zinthu zolemetsa ndizowopsa.

kuchokera pazomwe mukupereka top Kutengera kutulutsa kwalamulo, katundu wa VPS wanu ndiwokwera kwambiri, ndipo kuchuluka kwake kumafikira 54.22 (mphindi 1 yomaliza), 34.14 (mphindi 5 zapitazi), ndi 32.00 (mphindi 15 zapitazi).

Izi zikuwonetsa kuti makina anu akugwiritsa ntchito kwambiri. VPS yanu ili ndi 4-core CPU ndi 16GB RAM, koma kukumbukira kogwiritsidwa ntchito ndi 13,411,120KiB, komwe 781,120KiB yokha ndiyo imagwiritsidwa ntchito ngati buffer.

Malinga ndi top Kuchokera pamawu olamula, mutha kuwona kuti pali njira zingapo zopangira zinthu zambiri:

• mariadbd (MariaDB database service):Imatengera zinthu zambiri za CPU (143.1%).
• memcached:Amakhala ndi kuchuluka kwa CPU (7.7%).
• Njira zingapo za php-cgi:Iliyonse imatenga ma CPU ena ndi zida zokumbukira.

Momwe mungathetsere kuchuluka kwa VPS?

Njira zothetsera kulemetsa kwakukulu zingaphatikizepo:

1. Konzani database:Ngati mariadbd itenga ma CPU ambiri, mungafunikire kukhathamiritsa mafunso a Nawonsomba kapena kuganizira zoonjezera zomwe zili pa seva ya database.
2. Konzani mapulogalamu a PHP:Popeza pali njira zingapo za php-cgi zomwe zimatenga CPU yambiri ndi kukumbukira, mungafunike kukhathamiritsa ntchito yanu ya PHP kapena zolemba kuti muchepetse kugwiritsa ntchito zinthu.
3. Chepetsani kuchuluka kwa njira:Ganizirani kugwiritsa ntchito zina monga nginx's worker_processes kapena PHP-FPM's pm kukhazikitsa kuti muchepetse kuchuluka kwa njira.
4. Zowonjezera zothandizira:Ngati kukhathamiritsa sikukwaniritsa zosowa zanu, mungafunike kukweza VPS yanu kuti ikhale ndi ma cores ambiri kapena RAM yochulukirapo.
5. Yang'anirani ndikusanthula:Gwiritsani ntchito zida zowunikira zapamwamba kwambiri kuti muwunikenso kagwiritsidwe ntchito kazinthu ndikuzindikira zolepheretsa.
6. Kusanja katundu:Ngati kuchuluka kwa magalimoto kuli gawo lavuto, lingalirani kugwiritsa ntchito kusanja katundu kuti mufalitse zopempha pamaseva angapo.

Musanaganizire kukweza VPS yanu, ndikulimbikitsidwa kuti muwongolere makina anu ndi mapulogalamu anu poyamba.

Kukweza zida za hardware kuyenera kuchitidwa ngati njira yomaliza ndipo pokhapokha zitatsimikiziridwa kuti zida zamakono sizingakonzedwe kuti zikwaniritse zosowa.

Momwe mungakhazikitsire malire a VPS?

Poika malire a ndondomeko, muyenera kuganizira izi:

• Nambala yazomwe zikuchitika:Mufunika malire oyenerera omwe ali apamwamba kuposa kuchuluka kwazinthu zomwe zikuchitika kuti musakhudze ntchito yabwinobwino.
• Zofunikira pa System ndi kugwiritsa ntchito:Mvetsetsani kuchuluka kwa machitidwe anu ndi mapulogalamu omwe amafunikira kuti ayendetse.
• Kugwiritsa ntchito zinthu:Yang'anirani CPU ndi kukumbukira kukumbukira kuti muwone malire oyenera ndikupewa kutopa kwazinthu.
  Poganizira kuchuluka kwazomwe zikuchitika pa seva yanu, tikulimbikitsidwa kuti musakhazikitse malire otsika kwambiri.

Malire omasuka, monga 50 kapena 100 pa malire ochepetsetsa ndi 100 kapena 200 pa malire ovuta, angakhale oyenera kwambiri. Mutha kusintha izi potengera kuchuluka kwa seva yanu ndi momwe amagwirira ntchito.

Ngati mwaganiza zosintha malire, yang'anani momwe seva yanu ikugwirira ntchito ndikukonzekera kubweza zosinthazo ngati zitatha. Panthawi imodzimodziyo, ganizirani kukhathamiritsa kagwiritsidwe ntchito ndi kachitidwe kachitidwe kuti muchepetse kuchuluka kwa njira zosafunikira.

MwaLinuxdongosolo, mukhoza kupita /etc/security/limits.conf Zokonda pafayilo zimachepetsa kuchuluka kwa mafayilo otseguka, mawonekedwe ake ndi awa:

<用户名或用户组> soft nofile <软限制值>
<用户名或用户组> hard nofile <硬限制值>

Zolinga zongoganizira zakhazikitsidwa:

elo hard nproc 1000
elo hard nofile 5000

VPS idakwezedwa kuchokera ku 4-core 16GB kupita ku dongosolo lokonzekera bwino

Zikuwoneka kuti pali njira pafupifupi 500 zomwe zikuyenda kwambiri, ndiye kodi ndikofunikira kukweza kasinthidwe ka seva? Ndi kasinthidwe ka seva kotani komwe tikulimbikitsidwa kukwezera?

Pongoganiza kuti pulogalamu yanu ikufunika kuyendetsa njira zambiri nthawi imodzi, ndipo mukufuna kuwonetsetsa kuti dongosololi lili ndi zinthu zokwanira zogwirira ntchitoyo, nazi malingaliro ena enieni:

• Chiwerengero cha ma CPU cores:Sinthani ku CPU yokhala ndi 8, 16, kapena ma cores, kutengera ngati pulogalamu yanu ingapindule ndi ulusi wambiri.
• kukula kwa kukumbukira:Wonjezerani kukumbukira mpaka 32GB, 64GB, kapena kupitilira apo, kutengera zomwe mukufuna kukumbukira komanso kuchuluka kwa njira zomwe mukugwiritsa ntchito.
• Zowonjezera:Ganizirani zowonjezera zina, monga seva yodzipatulira ya database kapena zolemetsa, kuti muwongolere magwiridwe antchito ndi kudalirika.

Kumbukirani kuti kukweza kasinthidwe ka hardware yanu si yankho ku zovuta zogwirira ntchito. Onetsetsani kuti nambala yanu yogwiritsira ntchito, mafunso a database, ndi masinthidwe a seva akonzedwa kuti atengere mwayi pazowonjezera za hardware.
