NetWorker: Kümelenmiş RHEL sunucu raporundaki yetkili komutlar "istenen hedef için geçerli sertifika yolu bulamıyor."

Summary: NetWorker, Yüksek Kullanılabilirlik kullanılarak bir RHEL/CentOS Linux kümesine yüklenmiştir. authc config komutları (authc_config, authc_mgmt) çalıştırıldığında komut "unable to find valid certification path to requested target" (talep edilen hedef için geçerli sertifika yolu bulunamıyor) yanıtı verir. ...

Symptoms

  • NetWorker sunucu dağıtımı, Yüksek Kullanılabilirlik kümeleme kullanılarak RHEL/CentOS 7.x veya 8.x Linux sunucularında yapılandırılmıştır. 
  • authc_config ve authc_mgmt bir sertifika yolu hatası geri gönderir:

Cause

NetWorker sunucuları /usr/sbin/networker.cluster kullanılarak kümeye eklemeden önce, bunlar bağımsız sunucular olarak yapılandırıldığında. /opt/nsr/authc-server/scripts/authc_configure.sh, yükleme sonrası çalıştırılır ve düğüm başına benzersiz sertifikalar sağlar. Paylaşılan konumda kullanılan sertifikalar, kümelenmiş nws kaynağının başlangıçta başlatıldığı etkin düğümden hangi düğümle eşleşmektedir? 
 

/nsr dizini, geçerli etkin düğüm olan düğüme bağlı olarak düğümler arasında hareket eden /nsr_share/nsr dizinine sembolik olarak bağlanır. /opt/nsr/authc-server/conf/authc.truststore her düğüm için yereldir ve bir yük devretme gerçekleştiğinde paylaşılamaz. Düğüm yük devretmesinden sonra /nsr/authc/conf/authc.keystore emcauthc sertifika imzaları /opt/nsr. ile eşleşmektedir. ilk düğümdeki sertifikalar mevcut etkin düğümde değil. 

Resolution

Çözüm:

Bu sorun aşağıdaki NetWorker sürümlerinde düzeltmiştir:
  • 19.8.0.4
  • 19.9.0.2
Listelenen NetWorker sürümlerinden (veya daha yeni bir sürüme) yükseltin. NetWorker paketleri şu adresten indirilebilir: https://www.dell.com/support/home/product-support/product/networker/drivers
 
NOT: NetWorker yükseltildikten ve kümelenmiş nws kaynağı oluşturulduktan sonra sertifika uyumsuzluğunun gözlemlendiği düğümde /opt/nsr/authc-server/scripts/authc_configure.sh dosyasını yeniden çalıştırmanız gerekir. Bu, uyumsuzluğu düzeltir.

Geçici Çözüm:

1. Sertifikaların pc'lerde etkin düğümle eşleştildiği düğümü olun. Bunun nasıl belirlenileceğinin örnekleri Belirtiler alanında gösterilmiştir. 
2. Pasif düğümde oturum açın (sertifikaların eşleşmesi mümkün değildir). 
3. Sanal küme kaynağına karşı bir sertifika dosyası oluşturmak için nsrssltrust komutunu kullanın: 

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

Örnek:

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. Oluşturulan sertifikanın imzasının etkin düğümdeki paylaşılan sertifikanın imzasıyla eş eş olduğunu onaylayın:

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

Örnek:

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. Uyumsuz sertifikalara sahip düğümde, yerel emcauthctomcat sertifikalarını authc.truststore ve cacerts dosyası üzerinden silin.

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'

NOT: Başarılı olursa hiçbir çıktı döndürülebilir.

6. nsrssltrust ile oluşturulan sertifikayı içe aktarma:

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

Test:

Sertifikaların artık geçerli olduğunu doğrulamak için yukarıdaki değişikliklerin

uygulandığı düğüme küme yük devretme: 1. Artık authc_mgmtveya authc_config komutları daha önce arızalı olan düğümde çalışacaktır:

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. Ek doğrulama için sertifikaların hem yerel hem de paylaşılan konumlardan eşleşmektedir:
