Uchishandisa faira senge swap memory (SWAP)

munyori: Maikel Llamaret Heredia Yakatumirwa pane saiti ye GUTL.

Kare kare, GNU / Linux, yaive yakaganhurirwa pakushandisa imwechete yekuchinjisa memory chikamu chehuwandu hwe 128 MB, chimwe chinhu chakashoropodzwa zvakanyanya nevanozvidza musimboti weLinus Torvalds.

Neraki, mazuva ano hakuna muganho wakadai, uye zvakare zvinokwanisika kushandisa yakawanda yekuchinjisa ndangariro sezvinodiwa kugutsa zvido zvechero hurongwa.

Dzimwe nguva, mushure mekuisa yedu system, tinozviwana isu tichida yekuwedzera ndangariro SWAP izvo zvataive takagadzirisa panguva yekumisikidza, chimwe chinhu chinogona kuitwa nenzira yakapusa nekuwedzera saizi yechikamu chakasarudzwa nekuda kwezvinangwa izvi. Asi ... Chii chekuita kana iwe usiri kuda kubata tafura yekuparadzanisa?

Chii chinonzi SWAP uye chinoshanda sei?

Inochinjisa ndangariro nzvimbo kana Swap, ndiyo inozivikanwa seyechokwadi ndangariro. Musiyano uripo pakati peicho chaicho uye chaiwo memory ndeyekuti chaiyo memory inoshandisa hard disk space pane module yekumusoro

Kana chaiyo ndangariro yapera, iyo system inoteedzera zvimwe zvemukati zvirimo kune ino swap memory space kuitira kuti iite mamwe mabasa.

Kushandisa SWAP kune mukana wekupa imwe yekuyeuka inodiwa kana chaiyo ndangariro yapera uye maitiro anoda kuitwa. Chinhu chakashata ndechekuti semhedzisiro yekushandisa nzvimbo pane rakaomarara dhisiki, kushandiswa kwedhisiki rakaomarara kunononoka.

Shandisa faira senge swap memory.

Iyi nzira haidi kuita shanduko kutafura yekuparadzanisa yedhisiki rakaomarara. Yakanangana nevashandisi vasina ruzivo, kune avo vanoda kunzvenga kutora njodzi kana vachichinja tafura yekuparadzanisa yavo hard drive, kana kune avo vanoda zvinopfuura dzimwe nguva swap memory, kana pane imwe nguva hwaro.

Tichifunga kuti iyo yekuchinjisa faira inogona kuiswa mune chero dhairekitori pane rakaomarara diski, iwo murairo unoitwa dd, achijekesa kuti zero zvichanyorwa (kana = / dev / zero) kugadzira iyo faira / chinja (che = / chinjana), mumabhuroko e1024 byte (bs = 1024) kusvikira wapedza imwe huwandu mumabheti (kuverenga = [huwandu hwakawedzeredzwa nekukosha kwemabhs]). Muenzaniso unotevera unoita zviri pamusoro kusvikira 524288000 byte apera (akapatsanurwa ne1024 akaenzana 512MB):

Kugadzira iyo faira yatinozoshandisa seSAPAP, isu tichavhura koni uye tinyore zvinotevera (semudzi):

dd if=/dev/zero of=/swap bs=1024 count=512000

Nhanho iri pamusoro inogona kutora masekondi mashoma, ndapota shivirira. Wobva waomesa faira rakagadzirwa senge swap memory, isu tichaita iwo wekuraira mkswap, seinotevera (nguva dzose semudzi):

mkswap /swap

Iwe unozodzoserwa nezvakabuda pane iyo koni yakafanana neinotevera:

Kugadzirisa swapspace vhezheni 1, saizi = 511996 KiB hapana chitambi, UUID = fed2aba5-77c6-4780-9a78-4ae5e19c506b

Kugonesa kukamura, uye nekuishandisa ipapo nehurongwa hwekushandisa, ita rairo swapon. Muchiitiko chedu isu tichaita seyachinjana memory memory ku / swap faira ratakasika nekumisikidza SWAP mumatanho apfuura.

swapon /swap

Kuti uone kuti iyo nyowani yekuchinjisa faira iri kushandiswa nehurongwa hwekushandisa, isu tichaita iwo wekuraira zvakare vakasununguka uye isu tichaona kuti kugona kweiyo nyowani faira kwawedzerwa kune yekutanga SWAP memory.

Kuti iyi faira ishandiswe sekuchinja memory otomatiki pane inotevera system bhutsu, isu tichagadzirisa  / etc / fstab (uchishandisa nano, gedit, kate, kwrite, vim kana yakajeka mavara edhita yesarudzo yako), uchiwedzera mutsara unoenderana, seinotevera, uko panzvimbo pechigadzirwa, nzira yeiyo swap faira yakagadzirwa inoiswa:

Isu tinovhura iyo faira

nano /etc/fstab

Uye isu tinowedzera:

/swap         swap      swap     defaults               0 0

Ready !!!!

Tinogona kudzoreredza sisitimu uye kuyedza iyo yedu yekuchinjisa ndangariro yakawedzera nekushandiswa kweiyo nyowani faira SWAP. Zvakareruka zvatakaita kugadzira faira mumudzi wesystem, fomati iyo SWAP uye udza yedu GNU / Linux kuishandisa seyekuchinjisa ndangariro, pamwe chete nechikamu icho chatakatogadzirira ichi chinangwa.

Chimwe chinhu chiri nyore asi icho chingave chekushandisa kune vazhinji vedu ... Pasina imwezve ado ...
