Feem ntau cov yuav tsum commands SSH

SSH txib - qhov no yog ib tug tseem ceeb heev lub cuab tam rau tej system administrator los yog advanced webmasters uas party chaw dua pa hosting, thiab muaj nplooj siab neeg rau zaub mov. Configuring cov servers feem ntau tshwm sim uas siv cov Linux txib console.

Yuav kom txuas, koj muaj peev xwm siv ntau yam ntawm cov kev pab cuam, rau piv txwv, PuTTY. SSH kuj dab thiab Bitvise SSH Client. Nyob rau hauv qhov tseeb, lawv yog ib tug thiab tib yam. Yog li ntawd, feem ntau cov thawj coj yog siv ib yam dab tsi uas cia li siv.

PuTTY SSH

Hauv qab no yog sawv cev nyob rau hauv cov kev yees duab kev pab cuam PuTTY console. Thaum txuas mus rau tej kev pab cuam yuav tsum qhia kom meej rau tus tswv tsev (IP chaw nyob) ntawm neeg rau zaub mov thiab qhov chaw nres nkoj uas qhov no console yog khiav. Feem ntau nws yog 22 feeb chaw nres nkoj.

Ib txhia plhaub mus txuas rau lub neeg rau zaub mov kev mus nco ntsoov koj tus username thiab password. Qhov no yog tsis pom zoo. Qhov siab tshaj plaws uas yuav tsum tau muab cia - ID nkag mus nyob rau hauv thiaj li yuav piv tau lub chaw ua hauj lwm. Tab sis yeej ib txwm sau koj lo lus zais dua. Cov neeg tej zaum hacked, thiab ces hackers nyiag koj cov ntaub ntawv.

Bitvise SSH Client

Tsis tas li ntawd, lub SSH lub Linux txib ua hauj lwm zoo nyob rau hauv Bitvise SSH Client. Lub console yog tib yam, tab sis lwm yam tshaj li hais tias, qhov kev pab cuam yuav qhib tam sim ntawd FTP.

Siv yuav ua tau dab tsi. Qhov loj tshaj plaws hais tias koj nyiam nws thiab nws ua hauj lwm. Hauv paus ntsiab lus tib yam qhov txhia chaw.

SSH txib rau system xyuas

SSH-console commands cia rau koj saib xyuas neeg rau zaub mov. Nws yog txaus rau ntaus qhov hais kom ua htop. Cov no yog ib cov duab uas koj pom hauv qab no.

Tag nrho cov computers yuav txawv cov lus qhia. Nyob rau hauv cov ntaub ntawv no, muab cov uas qaug zog neeg rau zaub mov nrog ib tug processor thiab tsuas yog 671 MB RAM.

Suav Uptime qhia tau hais tias ntau npaum li cas lub sij hawm txij thaum lub system yog restarted. Yog hais tias lub chaw ua hauj lwm ntawm lub koom haum saib xyuas neeg rau zaub mov thiab tswj nws lub xeev raws li ib tug tag nrho ua hauj lwm, nws yuav ua hauj lwm rau ib ntev lub sij hawm yam tsis rebooting. Tom qab tag nrho, yog tias txhua yam hauj lwm zoo, vim li cas pib dua?

Nws yog ib qho tseem ceeb yog cov Load nruab nrab stitching nrog peb qhov tseem ceeb. Tus thawj qhia tau hais tias qhov nruab nrab load rau hauv lub xeem feeb, lub thib ob - rau lub xeem 5 feeb, peb - nyob rau hauv lub xeem 15 feeb. Qhov no load yuav tsum tau txiav txim raws li cov txheej txheem lub qhov rais Task Manager.

Lub load tej zaum yuav ntau dua li 100. Txawm ntau tshaj 200. Tus system ua hauj lwm raws li nram no: yog hais tias tus nyeem ntawv rau qhov kev xeem feeb yuav tsum tsawg tshaj los yog sib npaug zos rau 1 thiab nyob rau tib lub sij hawm rau ib tug hluas tub ntxhais computer, cov neeg rau zaub mov yuav lis cov load. Uas yog, muaj yuav tsum tau suav hais tias yog piv ntawm tus xov tooj ntawm cores thiab cov zauv ntawm qhov screen. Yog hais tias tag nrho cov 1 mus rau 1 los yog tsawg dua, ces nws yog ib qhov zoo. Lub sab tus nqi, tus ceev cov kev khiav hauj lwm qhov system raws li ib tug tag nrho.

Yog hais tias lub load rau ntawm ib tug dual-neeg rau zaub mov 4, lub load yog ntau tshaj 2 lub sij hawm tau rau ruaj khov lub lag luam. Sim kom ib lub qhov muag nyob rau hauv no daim duab. Yog hais tias ib tug loj load, sim optimize cov lag luam ntawm lub neeg rau zaub mov thiab hais tias ua hauj lwm muaj.

Load, raws li ib tug txoj cai, yuav ua tau ua hauj lwm nrog ib cov ntaub ntawv los yog ib tug database.

Siv htop hais kom ua tau cov neeg siv nyob rau hauv lub neeg rau zaub mov. Tiam sis saib tus load thiab xav tau ntawm tag nrho cov databases ntawm tag nrho cov neeg ua tau tsuas yog cov hauv paus hniav. Ua li no, nkag mus rau hauv lub neeg rau zaub mov ntawm SHH thiab nkag mus rau qhov hais kom ua mytop.

Ntawm no koj yuav saib tau tag nrho cov tam sim no thov nrog ncauj lus kom ntxaws:

• Lus nug ID (cov neeg rau zaub mov yog lawm, ntau dua qhov lub daim duab);
• tus neeg uas ua rau qhov kev thov;
• ib tug tswv tsev qhov twg ib tug thov tau;
• database;
• ntau npaum li cas lub sij hawm ib tug kev thov yog tsim;
• qhov kev thov nws tus kheej.

Qhov tseem ceeb tshaj no - lub sij hawm ntawm tiav. Cov coos dab yog nyob rau hauv qab. Yog hais tias koj pom tau tias ib co mysql-cov lus nug yog tua ib tug ob peb feeb, ces nws tsis yog ib txwm. Xovxwm k (tua ntawm cov lo lus), thiab nkag mus rau hauv lub ID. Raws li ib tug tshwm sim, koj yuav tau mus ua kom tiav qhov kev thov. Tua tag nrho cov ntau yam thiaj li thov thiab yuav tsum tau tshem khoom neeg rau zaub mov.

Tom ntej no, koj yuav tsum tau saib zoo li cas ntawm lub hauv paus thiab ib qho kev thov los mus kho qhov teeb meem (thiab nws yuav tshwm sim dua, thiab tej zaum koj yuav tsis tau mus manually ncaws problematic kab). Txiav txim seb lub coos thiab optimize lawv.

Basic Linux commands

Muaj ib tug ntau yam ntawm SSH commands. Tag nrho cov sib txawv cov hom phiaj. Piv txwv li:

• mus ua hauj lwm nrog cov ntaub ntawv;
• mus tso saib lub system ntaub ntawv;
• txheej txheem kev tswj;
• archiving;
• rau lub network;
• mus ua hauj lwm nrog mysql;
• mus nrhiav tau rau;
• muab cov saib txoj cai rau cov ntaub ntawv;
• rau nruab ib lub pob.

Xav txog tag nrho cov xaiv teb tau. Rau feem ntau ntawm lawv koj yuav pom me ntsis raws li koj ua hauj lwm nrog cov console.

Tam sim no cia peb xav txog qhov yooj yim commands uas koj xav tau txhua sij hawm, nyob qhov twg. Yog hais tias koj nco ntsoov lawv, koj yuav yeej ib txwm nco ntsoov.

Ua hauj lwm nrog ntaub ntawv

Nco ntsoov tias txoj kev nyob rau hauv lub commands yuav tsum tau sau raws li nyob rau hauv qhov chaw uas koj nyob. Piv txwv li, ls hais kom ua yuav muab ib daim ntawv teev cov tam sim no directory. Zaus rau hauv folders los ntawm cd koj yuav ua li cas tam sim ntawd mus rau sab xis, es ib tug los ntawm ib tug.

Yuav saib txoj kev uas koj sau nyob rau hauv pawg. "Daim npog qhov ncauj" kuj yuav siv tau. Piv txwv li, rau rho tawm tag nrho cov ntaub ntawv yuav tsum TXT, typing rm * .txt. Nyob rau hauv lub cim hais txog dab tsi, raws li ntev raws li qhov kawg twb .tht.

archiving cov ntaub ntawv

Yuav kom nyeem no qhov teeb meem, xyuas tus yees duab hauv qab no.

system ntaub ntawv

Cov yooj yim commands muaj qhia nyob rau hauv cov kev yees duab.

software installation

Tsis yog txhua txhua SSH commands tshuab txais tam sim ntawd tom qab lub installation ntawm cov operating system. Muaj ntau hlauv taws xob yuav tsum tau ntsia. Nws yog heev yooj yim.

Piv txwv li, htop hais kom ua thiab mytop Ameslikas muaj tsis mus. Lawv yuav tsum tau ntsia. Ua li no, nkag mus rau sudo apt-mus nruab htop.

Koj yuav tsum mus nruab los ntawm lub hauv paus. Lwm tus yuav tsis pub.

Lub hauv paus ntsiab lus ntawm cov installation yog tib yam rau tag nrho cov kev pab cuam. Cia li nyob rau thaum xaus es tsis txhob hloov htop mus rau lub yam nqi hluav taws xob (ntxiv).
