Awukwazi ukuqhagamshela kwiVultr VPS SSH?

Indlela yokuseta isitshixo sePuTTY

Ngenxa yokuba abasebenzisi abaninzi be-intanethi baseTshayina basebenzisa i-Vultr VPS ukuseta amajelo " okufikelela kwi-intanethi yesayensi ", inani elikhulu leedilesi ze-IP ze-Vultr livaliwe...

Khangela idilesi ye-IP

Okokuqala, kufuneka uqinisekise ukuba wenze idilesi ye-IP ye-Vultr. Ngaba ungafikelela kuyo kwilizwe lase China njengesiqhelo?

Isisombululo:

• Sebenzisa isixhobo se-intanethi ukubona iidilesi ze-IP ▼

Kufuneka ndenze ntoni ukuba idilesi yam yeVultr IP ivaliwe kwilizwe lase China?

• Nceda ujonge eli nqaku ngesisombululo ▼

Ukungena kwesitshixo se-SSH

Ngelixa i-VPS ibonakaliswe kwi-intanethi, umntu uya kuqhubeka nokunyanzelisa igama eliyimfihlo le-SSH ukuba ungene.

Ngoko ke kuyimfuneko ukuba ungene ngezitshixo ze-SSH, kwaye ucime igama eliyimfihlo.

Sebenzisa lo myalelo ulandelayo ukujonga ukungena kwegunya labanye abantu kwi-password yakho ye-SSH:

grep "Failed password for invalid user" /var/log/secure | awk '{print $13}' | sort | uniq -c | sort -nr | more

Kweyethu iVPS ethengiweyo, nyanzela ngamandla ukuya kuthi ga kumawakawaka amaxesha!Ungaya kwaye ubone ukuba mangaphi amaxesha oye wanyanzelwa ngenkohlakalo ngokwakho.

Isisombululo:

• Guqula imowudi yokungena kwi-SSH kwiqhosha le-SSH

Ukuveliswa kweqhosha le-SSH

Ukuba usebenzisa inkqubo yeWindows, kuya kufuneka usebenzise isoftware ye-puttygen ukuvelisa i-key pair.

Zombini iinkqubo zeLinux kunye neMacOS zinokusebenza ngqo kwisiphelo sendlela:

Inyathelo 1: Yenza isitshixo se-SSH

Nceda usebenzise lo myalelo ▼

ssh-keygen -t rsa -b 4096

Inyathelo lesi-2: Faka indawo yefayile ukuze ugcine isitshixo.

Enter file in which to save the key (/root/.ssh/id_rsa): 

• Nceda ucofe u-Enter

Inyathelo lesi-3: Uza kucelwa ukuba ufake igama lokugqitha.

Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 

• Ngenisa igama eligqithisiweyo, okanye unokucofa ngokulula u-Enter kwaye ulishiye lingenanto.

Ekugqibeleni uya kubona umyalezo wokuba izitshixo zakho zabucala kunye nekawonke-wonke zigcinwe apho:

Your identification has been saved in /root/.ssh/id_rsa. <== 私钥 

Your public key has been saved in /root/.ssh/id_rsa.pub. <== 公钥

Vultr VPS Qwalasela iSSH

Xa iVultr isenza iVPS, unokuseta ngokuthe ngqo ukungena kwesitshixo se-SSH.

Ukuba wenze iVPS kodwa awukaseta izitshixo ze-SSH...

Nceda ulandele la manyathelo angezantsi emva kokwenza okungasentla "isizukulwana sesitshixo se-SSH" kwiLinux:

Isiqendu 1:intando id_rsa.pub faka kwi a /root/.ssh ulawulo kwaye unike igama kwakhona ku authorized_keys

Inyathelo 2:guqula kancinane /etc/ssh/sshd_config ifayile yoqwalaselo

RSAAuthentication yes #RSA认证
PubkeyAuthentication yes #开启公钥验证
AuthorizedKeysFile .ssh/authorized_keys #验证文件路径
PasswordAuthentication no #禁止密码认证
PermitEmptyPasswords no #禁止空密码

Inyathelo lesi-3: Qala kwakhona inkonzo ye-SSH

• Iisenti7 Sebenzisa lo myalelo:systemctl restart sshd
• Centos6 sebenzisa umyalelo:/etc/init.d/sshd restart

I-PuTTY yenza izitshixo

Ukuba ungena kwiVPS usebenzisa inkqubo yeWindows, kuya kufuneka ukhuphele isitshixo sabucala kumxhasi kwaye uyiguqulele kwifomathi esetyenziswa yiPuTTY.

• Awunayo isoftware yePuTTY efakwe kwikhompyuter yakho?Nceda uGoogle okanye uphendlo lweBaidu: Khuphela iPuTTY.

Inyathelo 1: Sebenzisa iWinSCP, iSFTP, okanye ezinye izixhobo ukukhuphela ifayile yesitshixo sabucala id_rsa kumatshini weklayenti.

Inyathelo lesi-2: Vula iPuTTYGen.exe

Inyathelo lesi-3: Cofa iqhosha elithi Layisha kwiZenzo ▼

Inyathelo lesi-4: Layisha ifayile yesitshixo sabucala osandula ukuyikhuphela

Ayikwazi ukubonisa ifayile yesitshixo sabucala?Nceda ukhethe "Yonke ifayile (*.*)" ▲

• Ukuba useta nje igama lokutshixa, kufuneka ufake igama lokugqitha ngeli xesha.
• Emva komthwalo oyimpumelelo, iPuTTYGen iya kubonisa ulwazi olunxulumene nesitshixo.

Inyathelo lesi-5: Cofa iqhosha elithi "Gcina isitshixo sabucala" ukuze ugcine ifayile yesitshixo sabucala esihambelana nePuTTY. ▼

Indlela yokumisela iPutty?

La manyathelo alandelayo okuseta iPuTTY ukuze ungene kwiseva yeLinux usebenzisa isitshixo sabucala:

Inyathelo 1: I-Putty → Iseshoni: Faka Igama Lomsingathi (okanye Idilesi ye-IP)

Inyathelo lesi-2: I-Putty → Uqhagamshelo → Umhla: Faka "ingcambu" kwicandelo lomsebenzisi lokungena ngokuzenzekelayo.

Inyathelo lesi-3: PuTTY → Uqhagamshelo → SSH → Ugunyaziso: Kwifayile yesitshixo sabucala sokuqinisekisa, khetha ifayile yesitshixo sabucala esenziwe yiPuTTYGen ngaphambili. ▼

Inyathelo lesi-4: Buyela kwi-PuTTY → Iseshoni: Iseshoni egciniweyo, faka igama uze uligcine. Emva koko, ungangena ngokuthe ngqo ngokucofa kabini igama.

Inyathelo lesi-5: Uya kukwazi ukungena kwiLinux ngaphandle kwegama eligqithisiweyo. Nceda ukhumbule ukugcina ifayile yakho yesitshixo sabucala.
