NetWorker (Linux): Opgradering til NetWorker 19.13 kan ikke konfigurere AUTHC-server

Summary: Opgradering af en Linux NetWorker-server til 19.13.x fra en tidligere version rapporterer en Java-fejl under AUTHC-installationen.

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-godkendelsestjenesten rapporterer følgende fejl ved opgradering til 19.13.x fra en tidligere version:

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 fejl returneres, når du kører AUTHC-konfigurationsscriptet: /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.

BEMÆRK: Det problem, der beskrives i denne KB, gælder også for 19.13 NetWorker Management Console (NMC) og NetWorker Web User Interface (NWUI)-servere.

Cause

NetWorker 19.13 kræver Java Development Kit (JDK) 17. NetWorker-serveren bruger Java Runtime Environment (JRE) 1.8, som blev brugt af 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
BEMÆRK: Installationsvejledningen til NetWorker 19.13 beskriver Java-kravene til 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-licenseret JDK 17. NRE er tilgængelig via: 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


Efter opgradering til JDK 17 skal du køre authc_configure.sh Script til konfiguration 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

Det problem, der beskrives i denne KB, vises også under nye implementeringer af 19.13, hvis JDK 17-kravene ikke er opfyldt.
