2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

NCO TSEG: shinken tau hloov kho zaum kawg hauv MAR2016 rau kev tso tawm ruaj khov ntawm 2.4.3. Yog li, ntau xyoo dhau los kuv tau txav mus rau lwm txoj hauv kev los saib xyuas lub network hauv tsev. Ib qho ntxiv, php5 tsis zoo li tsis muaj

Yog li, thov tsis txhob siv cov lus qhia no!

Nruab thiab teeb tsa qhov hloov tshiab kawg ntawm shinken Network Monitor rau lub tsev lossis kev lag luam me.

Ntawm kev ua haujlwm, kuv pab pawg tsim kho software rau ntau dua 75 chav kawm server, nrog ntau dua 300 qhov xwm txheej hauv ntau lub chaw khaws ntaub ntawv thiab cov ntsiab lus ntawm qhov muaj. Muaj pab pawg ua haujlwm paub dhau los uas saib xyuas thiab khaws cov servers no khiav 24x7. Kuv tsis muaj dab tsi ze rau lawv cov kev paub lossis kev txawj ntse. Dhau li ntawm kuv tus kheej, Kuv tsis muaj leej twg txhawb nqa kuv lub tsev network. Thiab, Kuv xav siv sijhawm xoom sijhawm saib xyuas thiab tswj hwm kuv lub tsev network.

Kuv lub tsev LAN muaj ntau dua 40 qhov khoom siv sib txuas, uas yog qhov loj dua qhov kuv xav tau. Ntau lub tsev, tej zaum txawm tias yog koj li, muaj cov khoom siv sib txuas coob. Piv txwv ntawm cov khoom siv sib txuas yog:

• laptops thiab ntsiav tshuaj
• eBook nyeem ntawv
• xov tooj ntawm tes
• zes cua sov, ntsaws lub qhov rooj
• kev ruaj ntseg, dej system
• ntse TVs, tus txais U-nqe lus thiab DVR
• streaming media servers (Apple TV, Roku, ChromeCast FireStick)
• raspberry pi tsev automation tej yaam num

Raws li ntau lub cuab yeej hauv tsev tau txuas nrog, Kuv cia siab tias kuv lub network yuav loj tuaj.

Vim li cas tsev thiaj yuav tsum muaj lub network saib xyuas? Muaj cov servers thiab cov kev pabcuam tseem ceeb ntawm lub network hauv tsev. Piv txwv ntawm cov servers tseem ceeb suav nrog: ISP lub qhov rooj, qhov nkag tsis siv tau, kev ruaj ntseg, thiab kev siv dej. Piv txwv ntawm cov kev pabcuam tseem ceeb suav nrog: thaub qab PCs lossis MACs, kom ntseeg tau tias Wi-nkaus lossis internet tau ua haujlwm ntawm qhov xav tau ceev. Txhawm rau kom ntseeg tau cov kev pabcuam tseem ceeb/cov server ua haujlwm, lawv yuav tsum tau tshuaj xyuas tus kheej ntawm cov sijhawm sib xws, uas xav tau sijhawm ntau. Xwb, cov servers yuav tsum raug tshuaj xyuas siv lub network saib xyuas, uas sim kho qhov teeb meem thiab xa lus ceeb toom yog tias nws tsis tuaj yeem kho tau.

Shinken yog Network Monitor uas khiav ntawm ib lub computer. Hauv cov lus qhia no, Kuv yuav ua kom nws khiav Raspberry Pi (2 lossis 3) khiav Diet-Pi lossis raspbian.

Muaj ntau daim ntawv thov tshuaj xyuas lub network zoo. Piv txwv yog: SolarWinds, NetCool, thiab nagios. Cov ntawv thov no muaj peev xwm tshuaj xyuas, txheeb xyuas teeb meem, kho tus kheej thiab xa ntawv ceeb toom.

Feem ntau, Kuv tau sim ua kom kuv lub network cov nqi qis thiab yooj yim los tswj thiab hloov kho. Kuv tau nqaim kuv qhov kev tsom mus qhib cov ntawv thov sau ua tsawg hom lus. Kuv hom lus xaiv yog: nab nab, bash, html thiab css.

Shinken yog qhov qhib qhov rov sau dua ntawm nagios hauv nab hab sej. Yog li, shinken haum rau hauv kuv cov kev txwv thiab ua tau raws li kuv xav tau.
