Debian 9: MySQL(MariaDB)은 8에서 업그레이드한 후 더 이상 작동하지 않습니다.

방금 데비안 8에서 9로 업그레이드했습니다.

분명히 그것은 데이터베이스와 관련된 모든 것을 깨뜨립니다. 지금 MySQL을 시작할 수 없습니다. 오류는 다음과 같습니다.

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2 "No such file or directory")

서비스 상태:

systemctl status mariadb.service

journalctl -xe` that maybe useful: `2 02 16:42:39 doraemoe systemd[5505]: mariadb.service: Failed at step EXEC spawning /etc/mysql/debian-start: No such file or directory

어떻게 해결할 수 있나요?

편집하다:완전한 출력입니다.journalctl -u mariadb.service

답변1

어떤 이유로 파일이 없으며 /etc/mysql/debian-start다음과 같은 오류가 발생합니다.

16:55:25 doraemoe systemd[6859]: mariadb.service: Failed at step EXEC spawning /etc/mysql/debian-start: No such file or directory

설치를 확인했는데 mariadb파일이 mariadb-server-10.1패키지의 일부입니다. 비슷한 것이 있는지 확인하고 /etc/mysql/debian-start.dpkg-dist, 있으면 이름을 /etc/mysql/debian-start.

그렇지 않으면 설치한 정확한 패키지 이름을 확인하세요.

dpkg -S /usr/bin/mysqld_safe

mariadb-server-10.1: /usr/bin/mysqld_safe

.deb 패키지를 다운로드합니다(예:이 페이지를 통해), 압축을 푼다:

dpkg-deb --extract mariadb-server-10.1_10.1.26-0+deb9u1_amd64.deb /tmp/mariadb-server

(다운로드한 파일 이름을 바꿉니다.) 그런 다음 파일을 복사합니다.

cp /tmp/mariadb-server/etc/mysql/debian-start /etc/mysql/

그러면 더 이상 누락된 파일이 없으면 시작할 수 있습니다. 이상하게도 이 파일이 없어야 하므로 어떤 단계에서 문제가 발생했습니다.

시도 해봐systemctl start mysqld
