Summary: NetWorker er installert på en RHEL-/CentOS Linux-klynge ved hjelp av høy tilgjengelighet. Når du kjører authc-konfigurasjonskommandoer (authc_config, authc_mgmt), returnerer kommandoen «unable to find valid certification path to requested target» (finner ikke gyldig sertifiseringsbane til forespurt mål). ...

Symptoms

Implementeringen av NetWorker-serveren er konfigurert på RHEL-/CentOS 7.x- eller 8.x Linux-servere ved hjelp av klynger med høy tilgjengelighet.
kommandoene authc_config og authc_mgmt returnerer en sertifikatbanefeil:

Etter at en node-failover forekommer, er det manglende samsvar mellom sertifikatene på den delte /nsr-plasseringen og den lokale /opt/nsr-plasseringen på den nye aktive noden:

MERK: Når en node er aktiv /nsr er symbolsk knyttet til den delte banen (for eksempel: /nsr_share/nsr). Det er derfor sertifikatet i utdataene ovenfor samsvarer med når du sammenligner /nsr_share- og /nsr-utdataene. Denne banen deles mellom noder. Banene /opt/nsr og /opt/nre (Java) er imidlertid lokale for hver fysiske node. Sertifikatsignaturene mellom de delte sertifikatene og de lokale sertifikatene samsvarer ikke.

Når den andre noden er aktiv, samsvarer sertifikatene mellom «lokale» og «delte» baner

MERK: Angi passordet for authc keystore for -storepass-verdien. Passordet for authc keystore konfigureres under første konfigurasjon når du kjører skriptet /opt/nsr/authc-server/scripts/authc_configure.sh på hver node.

Sertifikatbanefeilen observeres ikke på noden der alle sertifikatene samsvarer:

root@NWrhelNodeE:~# authc_mgmt -u Administrator -p 'authc_password' -e find-all-users
The query returns 1 records.
User Id User Name
1000    administrator

Cause

Før NetWorker-servere legges til i klyngen ved hjelp av /usr/sbin/networker.cluster, er de konfigurert som frittstående servere. /opt/nsr/authc-server/scripts/authc_configure.sh kjøres etter installasjon, og genererer unike sertifikater per node. Sertifikatene som brukes på den delte plasseringen samsvarer med noden som var den aktive noden, der den klyngede nws-ressursen først ble startet på.

/nsr-katalogen er symbolsk knyttet til /nsr_share/nsr-katalogen som flyttes mellom noder, avhengig av hvilken node som er den gjeldende aktive noden. /opt/nsr/authc-server/conf/authc.truststore er lokal for hver node og deles ikke når en failover oppstår. Etter en node-failover samsvarer /nsr/authc/conf/authc.keystore emcauthc-sertifikatsignaturene med /opt/nsr.. sertifikater på den opprinnelige noden, men ikke den gjeldende aktive noden.

Resolution

Løsning:

Dette problemet er løst i følgende NetWorker-versjoner:

19.8.0.4
19.9.0.2

Oppgrader til en av de oppførte NetWorker-versjonene (eller nyere). NetWorker-pakker kan lastes ned fra: https://www.dell.com/support/home/product-support/product/networker/drivers

MERK: Etter at NetWorker har blitt oppgradert og den klyngede nws-ressursen er tatt opp, må du kjøre /opt/nsr/authc-server/scripts/authc_configure.sh på noden der sertifikatkonflikten ble observert. Dette korrigerer manglende samsvar.

Omgåelse av problemet:

1. Gjør noden der sertifikatene samsvarer med den aktive noden i PC-er. Eksempler på hvordan du fastslår dette, vises i symptomfeltet.
2. Logg på den passive noden (der sertifikatene ikke samsvarer).
3. Bruk nsrssltrust-kommandoen til å opprette en sertifikatfil mot den virtuelle klyngeressursen:

nsrsltrust -u https:// cluster-hostname:9090 -certificate_file.cer

Eksempel:

root@NWrhelNodeF:~# nsrssltrust -u https://NWrhelClusD.emclab.local:9090 -c emcauthctomcat.cer

Do you trust this certificate(s) entity based on above information? [yes]/[no]:
yes
Https certificate is saved into certfile [emcauthctomcat.cer].

4. Bekreft at signaturen til det genererte sertifikatet samsvarer med signaturen til det delte sertifikatet på den aktive noden:

cd /opt/nre/java/latest/bin
/opt/nre/java/latest/bin/keytool -printcert -file certificate_file.cer | grep SHA256

Eksempel:

root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -printcert -file /root/emcauthctomcat.cer | grep SHA256
         SHA256: 4C:A0:07:70:D2:04:4D:A2:F0:87:5A:75:4A:3A:9F:C3:B6:3A:C0:3B:05:F8:9C:F6:81:01:D5:8C:C7:CE:E6:B4

root@NWrhelNodeE:/opt/nre/java/latest/bin# ./keytool -printcert -file /nsr_share/nsr/authc/conf/emcauthctomcat.cer | grep SHA256
         SHA256: 4C:A0:07:70:D2:04:4D:A2:F0:87:5A:75:4A:3A:9F:C3:B6:3A:C0:3B:05:F8:9C:F6:81:01:D5:8C:C7:CE:E6:B4

5. På noden med manglende samsvarende sertifikater sletter du de lokale emcauthctomcat-sertifikatene fra filen authc.truststore og cacerts.

cd /opt/nre/java/latest/bin
./keytool -delete -alias emcauthctomcat -keystore /opt/nre/java/latest/lib/security/cacerts -storepass changeit
./keytool -delete -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password'

MERK: Hvis dette er vellykket, returneres ingen utdata.

6. Importer sertifikatet som genereres med nsrssltrust:

cd /opt/nre/java/latest/bin
./keytool -import -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password' -file certificate_file.cer
./keytool -import -alias emcauthctomcat -keystore/opt/nre/java/latest/lib/security/cacerts-storepass changeit -file certificate_file.cer

Eksempel:

root@NWrhelNodeF:/opt/nre/java/latest/bin# ./keytool -import -alias emcauthctomcat -keystore /opt/nsr/authc-server/conf/authc.truststore -storepass 'authc-password' -file /root/emcauthctomcat.cer

Test:

Hvis du vil validere at sertifikatene nå er gyldige, kan du failovere klyngen til noden som endringene ovenfor ble brukt på:

1. Kommandoene authc_mgmt eller authc_config skal nå fungere på noden de tidligere mislyktes i:

root@NWrhelNodeF:~# authc_mgmt -u Administrator -p 'NetWorker_Admin_password' -e find-all-users
The query returns 1 records.
User Id User Name
1000    administrator

2. For ytterligere verifisering kan vi se at sertifikatene samsvarer fra både lokale og delte plasseringer:

Additional Information

Hvis AUTHC-/NMC-serveren er et sentralt frittstående NetWorker-system, vil ikke dette problemet påvirke NetWorker Management Console (NMC), NetWorker Web User Interface (NWUI) eller REST API-forespørsler.
