Tsim VPC nrog Public thiab Private subnets
- Tsim VPC. Nkag mus rau AWS tswj console thiab mus rau VPC console.
- Tsim Public Subnet . Ua Nco ntsoov xaiv "MyVPC" hauv qab "VPC" cov ntawv qhia zaub mov thiab nkag mus 10.0.
- Tsim Private Subnet . Tam sim no tsim Private subnet CIDR 10.0.2.0/24.
- Tsim thiab txuas "Internet Gateway"
- Ntxiv ib txoj hauv kev rau Public Subnet .
Ua li no, koj yuav kuaj xyuas seb lub subnet yog pej xeem lossis ntiag tug AWS li cas?
Yog li ntawd, rau txiav txim yog tias ib muab subnet yog pej xeem lossis ntiag tug , koj yuav tsum tau piav qhia txog txoj kab lus uas cuam tshuam nrog qhov ntawd subnet . Qhov ntawd yuav qhia koj txoj kev thiab koj ua tau xeem rau 0,0. 0.0/0 txoj kev nrog lub rooj vag ID ntawm igw-xxxxxxxxxxxxxxxxxxxx (as opposed to local). Ntawm no, koj tuaj yeem pom txoj hauv kev ntawm 0.0.
Tsis tas li ntawd, dab tsi yog qhov private subnet hauv AWS? Amazon VPC Concepts Cov hauv qab no yog cov ntsiab lus tseem ceeb rau VPCs: Ib qho virtual tus kheej huab (VPC) yog lub network virtual tshwj xeeb rau koj AWS tus account. A subnet yog ntau qhov chaw nyob IP hauv koj VPC. Ib lub rooj sib tham muaj cov cai, hu ua txoj kev, uas yog siv los txiav txim seb qhov twg yog qhov kev sib txuas hauv network.
Kuj paub, dab tsi yog pej xeem thiab ntiag tug subnet hauv AWS?
A pej xeem subnet nrog qhov loj / 24 IPv4 CIDR (piv txwv: 10.0. 0.0/24). Qhov no muab 256 tus kheej IPv4 chaw nyob. A pej xeem subnet yog a subnet uas yog txuam nrog ib txoj kab lus uas muaj ib txoj kev mus rau lub rooj vag hauv Internet. VPN nkaus xwb subnet nrog qhov loj me / 24 IPv4 CIDR (piv txwv: 10.0.
Vim li cas VPC yog dab tsi?
Default VPC yog ib lub network Virtual uas tau tsim los rau cov neeg siv khoom AWS tus lej 1st lub sijhawm EC2 cov peev txheej tau muab. Ntawm qhov tod tes, ib qho tsis raug cai (tseem hu ua Cov Neeg Siv Khoom VPC ) tsis tuaj yeem tsim thaum EC2 cov peev txheej tau muab thiab cov neeg siv khoom xav tau los tsim tus kheej VPC.

Yuav ua li cas koj thiaj paub tias lub subnet yog pej xeem lossis ntiag tug?
'tus kheej'. Public subnets muaj ib txoj hauv kev mus rau Internet Gateway; private subnets tsis muaj. Yog li, txhawm rau txiav txim siab seb lub subnet puas yog pej xeem lossis ntiag tug, koj yuav tsum piav qhia txog cov lus qhia uas cuam tshuam nrog lub subnet ntawd. Qhov ntawd yuav qhia koj txog txoj hauv kev thiab koj tuaj yeem sim rau 0.0
Dab tsi yog tus yuam sij ntiag tug thiab pej xeem tus yuam sij hauv Blockchain?
Thaum ib tug neeg xa koj cryptocoins hla Blockchain, lawv tau xa lawv mus rau qhov hashed version ntawm qhov hu ua "Public Key". Muaj lwm tus yuam sij uas zais ntawm lawv, uas yog hu ua "Private Key." Qhov Private Key no yog siv los muab Public Key
Koj txhais li cas los ntawm tus yuam sij ntiag tug thiab pej xeem tus yuam sij cryptography?
Nyob rau hauv pej xeem tus yuam sij cryptography, ob tus yuam sij yog siv, ib tug yuam sij yog siv rau encryption thiab thaum lwm yam yog siv rau decryption. 3. Nyob rau hauv private keycryptography, tus yuam sij yog khaws cia tsis pub leejtwg paub. Nyob rau hauv pej xeem tus yuam sij cryptography, ib qho ntawm ob tus yuam sij yog khaws cia tsis pub leejtwg paub
Kuv yuav ua li cas thiaj tsim tau tus yuam sij ntiag tug thiab pej xeem hauv OpenSSL?
Tsim Public thiab Private Keys nrog openssl.exe Hauv Windows: Qhib Command Prompt (Start> Programs> Accessories> Command Prompt). Nias ENTER. Tus yuam sij ntiag tug yog tsim thiab khaws cia rau hauv cov ntaub ntawv npe 'rsa. Tsim tus yuam sij ntiag tug - Linux. Qhib lub Terminal. Nkag mus rau hauv daim nplaub tshev nrog ListManager directory. Nias ENTER. Qhib lub Terminal
