Centos Tomcat 8.5에서 프로젝트를 startup하면 발생하는 에러입니다.
그전까지 잘 실행되던 프로젝트인데 오늘 프로세스를 죽였다가 재실행하니 이런 오류와 함께 동작하던 사이트 접속이 거부되고있습니다.
StackOverFlow나 다른 해결책을 구글에서 검색해 보았는데 에러를
org.apache.catalina.core.AprLifecycleListener.lifecycleEvent The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path:
에 관련된 에러
org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

관련된에러 2가지로 나뉘어서 검색해봤습니다. 관련 블로그를 참조하여 읽고 적용해보았는데 변함없이 동일한 에러가 떠 질문드리게됬습니다.
어떤 오류인지와 어떻게 해결해야 할 지가 궁금합니다.
어떤 분들은 APR문제라 하시며 다운 받으라는 해결책도 있었고, tomcat conf에 logging.p~에서 필요한 logger.level = FINE 으로 변경하라고도 하셨는데, 신중하게 해결하고자 접근중입니다. 다운로드는 시도하지 않았고(왜 이유를 알고 해결하고자..) logging.p~ 에서는 logger level을 변경해 JARs파일을 찾으라는 의도 같길래 시도해봤는데 JARs파일을 발견하기 힘들어서 여기 까지 왔습니다..
아래는 log 일부입니다.
