NetWorker (Linux): Oppgradering til NetWorker 19.13 Kan ikke konfigurere AUTHC-serveren

Summary: Hvis du oppgraderer en Linux NetWorker-server til 19.13.x fra en tidligere versjon, rapporteres det om en Java-feil under AUTC-installasjonen.

This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Symptoms

NetWorker-godkjenningstjenesten rapporterer følgende feil ved oppgradering til 19.13.x fra en tidligere versjon:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/emc/brs/auth/util/ServiceConfigurator has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Den samme feilen returneres når du kjører autorisasjonsskriptet AUTC: /opt/nsr/authc-server/scripts/authc_configure.sh

[root@lnx-srvr01 linux_x86_64]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

The installation process will install an Apache Tomcat instance.
For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

MERK: Problemet som beskrives i denne KB-en, gjelder også for 19.13 NetWorker Management Console (NMC) og NWUI-servere (NetWorker Web User Interface).

Cause

NetWorker 19.13 krever Java Development Kit (JDK) 17. NetWorker-serveren bruker Java Runtime Environment (JRE) 1.8, som ble brukt av NetWorker 19.12 og tidligere.

[root@lnx-srvr01 linux_x86_64]#  sudo find /usr /opt /lib* -type f -name "java" 2>/dev/null
/opt/nre/java/jre1.8.0_421/bin/java
MERK: Installasjonsveiledningen for NetWorker 19.13 inneholder informasjon om Java-kravene for NetWorker-komponenter. https://www.dell.com/support/product-details/product/networker/docs

Resolution

Installer NetWorker Runtime Environment (NRE) 17.0.1 (eller nyere) eller Oracle-lisensiert JDK 17. NRE er tilgjengelig gjennom: https://www.dell.com/support/product-details/en-us/product/networker/drivers

Creating the installation log in /opt/nre/logs/install.log.

Performing initialization. Please wait...

NRE configuration completed


Når du har oppgradert til JDK 17, kjører du authc_configure.sh Skript for å konfigurere authc:

[root@lnx-srvr01 ~]# /opt/nsr/authc-server/scripts/authc_configure.sh

Specify the directory where the Java Standard Edition Runtime Environment (JRE) software is installed [/opt/nre/java/latest]:

The installation process will install an Apache Tomcat instance.
For optimum security, EMC NetWorker Authentication Service will
use a non-root user (nsrtomcat) to start the Apache Tomcat instance.
If your system has special user security requirements, ensure that proper
operational permissions are granted to this non-root user (nsrtomcat).
Please refer to NetWorker Installation Guide.

The Apache Tomcat will use "lnx-srvr01.networker.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.

Creating the installation log in /opt/nsr/authc-server/logs/install.log.

Performing initialization. Please wait...


The installation completed successfully.

[root@lnx-srvr01 ~]# systemctl start networker

Additional Information

Problemet som er beskrevet i denne KB-en, vises også ved nye implementeringer av 19.13 hvis JDK 17-kravene ikke oppfylles.
