Cause

JRE 설치에 더 이상 NetWorker Tomcat 인증(emcauthctomcat) vSphere Web Client VM 백업 및 복구 플러그인에서 사용하는 인증서입니다. 

Resolution

emcauthctomcat 인증서를 Java JRE 키 저장소 구성으로 가져와야 합니다. 다음은 인증서가 있는지 확인하고 인증서를 가져오는 개요입니다.

  1. NetWorker Server에서 Windows 명령 프롬프트 또는 Linux 터미널 세션을 엽니다.
  2. Java JRE 설치 디렉토리로 변경합니다. 디렉토리는 설치된 Java JRE 버전에 따라 변경됩니다.  
JRE 1.8.0_151의 설치 경로 예
  • Windows: C:\Program Files\Java\jre1.8.0_151\bin>
  • Linux: /usr/java/jre1.8.0_151/bin
NRE(NetWorker Runtime Environment) 설치 예:
  • Windows: C:\Program Files\NRE\java\jre#.#.#_###\bin
  • Linux: /opt/nre/java/latest/bin
  1. keytool 명령줄 유틸리티를 사용하여 인증서가 Java JRE cacerts 키 저장소에 존재하지 않는지 확인합니다.
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts | grep emc
  1. keytool 명령줄 유틸리티를 사용하여 emcauthctomcat 증명서:
    • Windows:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file "C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\conf\emcauthctomcat.cer"  -keystore ..\lib\security\cacerts
  • Linux:
keytool -importcert -storepass changeit -trustcacerts -alias emcauthctomcat -file /nsr/authc/conf/emcauthctomcat.cer -keystore ../lib/security/cacerts 
  1. keytool 명령줄 유틸리티를 사용하여 인증서가 이제 Java JRE cacerts 키 저장소에 있는지 확인합니다.
    • Windows:
keytool -list -storepass changeit -keystore ..\lib\security\cacerts | findstr emc
  • Linux:
keytool -storepass changeit -list  keystore ../lib/security/cacerts  | grep emc
