NetWorker：叢集 RHEL 伺服器上的 authc 命令報告「找不到要求目標的有效認證路徑」。

Summary: NetWorker 已使用 High Availability 安裝在 RHEL/CentOS Linux 叢集上。執行 authc config 命令 （authc_config，authc_mgmt） 時，命令傳回「unable to find valid certification path to requested target」。

Symptoms

  • NetWorker 伺服器部署是在使用高可用性叢集的 RHEL/CentOS 7.x 或 8.x Linux 伺服器上進行設定。 
  • authc_config 和authc_mgmt 命令傳回憑證路徑錯誤：

  • 節點容錯移轉發生後，共用 /nsr 位置的憑證與新使用中節點的本機 /opt/nsr 位置之間出現不相符的情形：

注意：當節點作用中 /nsr 以符號方式連結至共用路徑時 （範例：/nsr_share/nsr）。正因如此，在上述輸出中，憑證會與 /nsr_share 和 /nsr 輸出相符。節點之間共用此路徑;但是，/opt/nsr 和 /opt/nre （JAVA） 路徑是每個實體節點的本機。「共用」和「本機」憑證之間的憑證簽章不相符。
  • 當其他節點處於使用中狀態時，「local」和「shared」路徑之間的憑證會相符

注意：指定 -storepass 值的 authc keystore 密碼。在每個節點上執行 /opt/nsr/authc-server/scripts/authc_configure.sh 腳本時，會在初始設定期間設定 authc keystore 密碼。
  • 在所有憑證相符的節點上，不會發現憑證路徑錯誤：
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

在使用 /usr/sbin/networker.cluster 將 NetWorker 伺服器新增至叢集之前，這些伺服器會設定為獨立伺服器。/opt/nsr/authc-server/scripts/authc_configure.sh 會在安裝後執行，為每個節點產生唯一的憑證。在共用位置使用的憑證與以哪個節點為作用中節點的憑證相符，叢集 nws 資源最初是從哪個節點開始使用。 
 

/nsr 目錄以符號方式連結至 /nsr_share/nsr 目錄，該目錄會根據目前使用中的節點為哪個節點在節點之間移動。/opt/nsr/authc-server/conf/authc.truststore 是每個節點的本機，在發生容錯移轉時不會共用。節點容錯移轉後，/nsr/authc/conf/authc.keystore emcauthc 憑證簽章與 /opt/nsr 相符。初始節點上的憑證，但不是目前使用中的節點。 

Resolution

解決方案：

此問題已在下列 NetWorker 版本中修正：
  • 19.8.0.4
  • 19.9.0.2
升級到其中一個列出的 NetWorker 版本 （或更新版本）。NetWorker 套裝可從以下網址下載：https://www.dell.com/support/home/product-support/product/networker/drivers
 
注意：NetWorker 升級後，叢集 nws 資源隨即啟動，您必須在發現憑證不相符的節點上重新執行 /opt/nsr/authc-server/scripts/authc_configure.sh 。如此可修正不相符的情形。

The Apache Tomcat will use "lnx-node1.amer.lan" as the host name.
The Apache Tomcat will use "9090" as the port number.
The NetWorker Authentication Service requires a keystore file to configure encryption and to provide SSL support.
EMC recommends that you specify a keystore password that has a minimum of six characters.
Do you want to use the existing keystore /nsr/authc/conf/authc.keystore [y]?
Specify password for the existing keystore:
The install will use the existing certificate "emcauthctomcat" for Apache Tomcat.
The install will use the existing certificate "emcauthcsaml" for Authentication Service.
The NetWorker Authentication Service defines automatically an administrator user account

因應措施：

1.建立憑證與 pcs 中使用中的節點相符的節點。如何判斷這個問題的範例會顯示在「徵兆」欄位中。
2.登入被動節點 （其中憑證不符）。
3.使用 nsrssltrust 命令建立虛擬叢集資源的憑證檔案： 

nsrssltrust -u HTTPs:// cluster-hostname：9090 -cc ertificate_file.cer

例子：

root@NWrhelNodeF:~# nsrssltrust -u https://NWrhelClusD.emclab.local:9090 -c emcauthctomcat.cer
Fetching server's CA certificate chain / server certificate (if CA is not available)...

Information of the cert chain received from SSL server:

        idx: 0
        subject: /C=US/ST=TX/L=Round Rock/O=DELL/OU=NetWorker/CN=NWrhelNodeE.emclab.local

        signing algorithm: 1020

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

4.確認產生的憑證簽名與作用中節點上共用憑證的簽章相符：

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

範例：

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.在有不相符憑證的節點上，從 authc.truststore 和 cacerts 檔案中刪除本機 emcauthctomcat 憑證。

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'

注意：如果成功，則不會傳回任何輸出。

6.匯入以 nsrssltrust產生的憑證：

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

範例： 
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

Certificate already exists in keystore under alias <emcnwuiserv>
Do you still want to add it? [no]:  yes
Certificate was added to keystore
 

測試：

若要驗證憑證現在是否有效，請將叢集容錯移轉至節點，上述變更會套用至：

1。authc_mgmt或authc_config命令現在應在之前失敗的節點上運作：

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.如需其他驗證，我們可以看到來自本機和共用位置的憑證相符：

Additional Information

如果 AUTHC/NMC 伺服器是中央獨立 NetWorker 系統，此問題不會影響 NetWorker 管理主控台 （NMC）、NetWorker Web 使用者介面 （NWUI） 或 REST API 要求。
