AWS Networking: VPC Configuration for Public Instance Accessibility
Introduction
Raws li kev lag luam txav ntau ntawm lawv cov haujlwm mus rau huab, muaj kev nkag siab tob txog Amazon Web Services (AWS) thiab nws cov peev xwm sib txuas lus tau dhau los ua qhov tseem ceeb. Ib qho ntawm lub hauv paus tsim thaiv ntawm AWS networking yog Virtual Private Cloud (VPC) - lub network uas koj tsim hauv koj tus account AWS kom cais cov peev txheej koj khiav ntawm lwm tus neeg siv cov peev txheej. Hauv tsab ntawv tshaj tawm blog no, peb yuav tsom tshwj xeeb rau kev teeb tsa VPCs rau kev nkag mus rau pej xeem piv txwv. Thiab tom qab ntawd peb yuav siv VPC wizard los tsim cov rooj sib tham, subnets thiab net gateways kom tso cai rau koj mus cuag koj qhov piv txwv ntawm pej xeem hauv internet.
VPC Configuration
- Txhawm rau pib, rub lub console rau koj qhov piv txwv AWS. Mus rau VPC kev pabcuam hauv AWS thiab teeb tsa VPC, subnet, cov lus qhia thiab lub rooj vag hauv internet. Qhov no tuaj yeem ua tiav hauv vib nas this nrog AWS tus tshiab virtual private cloud creation tool.
- Ntaus VPC rau hauv AWS console search bar thiab mus rau koj VPCs. Xaiv Tsim VPC thiab xaiv VPC thiab lwm yam. Qhib nametag auto-generation thiab teem koj lub npe nyiam.
- rau lub IPv4 CIDR thaiv, teem rau 172.20.0.0/20. Tawm mus IPv6 CIDR thaiv faib tsis taus. Tawm mus Kev Sib Tw ntawm lub neej ntawd. Hloov muaj zones rau 1. Tawm ntawm Tus naj npawb ntawm pej xeem subnets ntawm 1 yog li peb tuaj yeem nkag mus rau peb daim ntawv thov hauv internet. Tawm ntawm Tus naj npawb ntawm cov subnets raws li 1. Teem NAT rooj vag rau Hauv 1 AZo tias peb muaj peev xwm nkag tau hauv internet. Peb yuav tsis siv S3 yog li peb tuaj yeem lov tes taw VPC kawg.
- Nco ntsoov tias DNS hostnames yog enabled thiab hais tias DNS daws teeb meem yog enabled. Qhov no yog qhov tseem ceeb rau kev nkag mus rau koj qhov xwm txheej los ntawm lub npe hostname thiab kev ruaj ntseg tsheb rau lawv nrog SSL encryption.
- xaiv Tsim VPC, tos rau cov txheej txheem tsim VPC kom ua tiav txhua kauj ruam thiab tom qab ntawd nyem Saib VPC.
- mus rau Subnets thiab xaiv lub subnet koj tsim.
- xaiv kev nqis tes ua thiab Kho kom raug subnet chaw. Pab kom nws pib-xaiv pej xeem IPv4 chaw nyob kom ntseeg tau tias pej xeem IPv4 chaw nyob raug muab rau qhov piv txwv ntawm khau raj lossis manually muab IPv4 chaw nyob rau koj qhov xwm txheej tom qab.
- Tom qab ntawd nyem txuag thiab koj ua tiav nrog kev teeb tsa network.
- Xaiv VPC thiab pej xeem subnet uas koj tsim thaum pib koj qhov piv txwv. Thiab koj yuav tuaj yeem tsim daim ntawv pov thawj yooj yim thiab nkag mus rau koj qhov xwm txheej hauv pej xeem hauv internet.
xaus
Hauv kev xaus, kev ua kom muaj kev nkag mus tau zoo rau pej xeem yog qhov tseem ceeb rau cov koom haum uas khiav cov kev pab cuam rau pej xeem hauv lawv qhov chaw AWS. Los ntawm kev siv lub peev xwm VPC kev sib txuas lus muaj zog, AWS cov neeg siv tuaj yeem teeb tsa lawv lub network kom muaj kev nyab xeeb thiab txhim khu kev qha rau lawv cov xwm txheej pej xeem thaum siv. zoo tshaj plaws rau kev ruaj ntseg network thiab piv txwv.
