postfix를 시작하려고 하면 다음 오류가 발생합니다.
/usr/sbin/postconf: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such...r directory
/usr/bin/newaliases: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No suc...r directory
/usr/sbin/postfix: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No suc...r directory
Postfix는 mysql을 설치하기 전까지는 잘 작동했습니다. mysql에 Postfix 오류가 발생하는 이유가 무엇인지 잘 모르겠습니다.
find . -name 'libmysqlclient*'명령을 실행하면 다음과 같은 결과가 나타납니다.
./usr/lib64/mysql/libmysqlclient.so.21
./usr/lib64/mysql/libmysqlclient.so.21.2.30

18 버전이 설치되어 있지 않은데 왜 21이 아닌 18을 찾는지 혼란스럽습니다.

누구든지 도와줄 수 있나요? 내 문제와 유사한 다른 게시물을 여기에서 확인했지만 시도할 수 있을 만큼 내 상황에 근접한 해결책을 찾을 수 없었습니다.
마지막으로 이 명령도 실행했는데 많은 정보가 출력되었으므로 이 게시물 끝에 저장했습니다.

답변1
업데이트 및 수정:
이 특정 문제를 파악하려고 몇 시간 동안 노력한 끝에 마침내 postfix를 제거하고 다시 설치하기로 결정했습니다. 좋은 소식은 이 기능이 작동하고 잃어버린 패키지를 찾는 데 도움이 된다는 것입니다.
내가 실행한 명령은 다음과 같습니다.
#yum remove postifix
#yum clean all
#yum install postfix
이제 설치 결과는 다음과 같습니다.
# yum install postfix
