MySQL을 다시 설치하는 방법?

소프트웨어 업그레이드로 인해 mysql이 고장 났으며 아직 복구 할 수 없었습니다.

의심되는 원인 : 부팅 디스크가 거의 찼습니다. 업그레이드는 완료하기 전에 디스크를 가득 채웠으므로 모든 것이 혼란에 빠졌습니다. 시스템에 더 많은 디스크를 제공하고 / var을 자체 파티션으로 옮겼습니다. 나는 여전히 mysql을 되살리려 고 노력하고있다.

아래는 내가 지금까지 시도한 것입니다 (모두 루트로). 먼저 mysql이 시작되지 않습니다 (443). (444, 445) 수정 시도가 실패합니다. mysql 및 (?) 의류 제거 시도가 실패합니다 (446, 7, 8). 더 활발한 mysql 제거 시도는 성공한 것으로 보이며 (449) 이전 오류가 더 이상 보이지 않습니다 (450, 1, 2). MySQL은 더 이상 존재하지 않기 때문에 재구성 할 수 없지만 (453) 다시 설치하려고하면 오래된 오류 메시지가 표시되고 다시 사각형으로 돌아갑니다 (454).

또한이 질문을 확인했습니다 (12.04 로의 업그레이드로 인해 중단되지 않았지만 12.10에서 이미 작동 중임) 12.04로 업그레이드 한 후 깨진 myslq-server 패키지를 수정 하고 제안 사항을 시도했습니다 (458, 461, 462) 소용이 없습니다.

다른 무엇을해야합니까?

먼저 MySQL을 제거하십시오.

sudo apt purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*

그런 다음 다시 설치하십시오.

sudo apt update
sudo apt install mysql-server
sudo mysql_install_db
sudo /usr/bin/mysql_secure_installation

우분투 16.04에서 내 경우에 수정하는 방법은 다음과 같습니다 ( 먼저 DB를 백업하십시오. 데이터베이스가 손실됩니다 ).

sudo apt remove --purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*
sudo apt install mysql-server

(어떻게 든, 내 이전 호출하는 apt purge mysql-server성공하는 것 같지 않았다. 나는 그 생각 apt purge foo에 해당했다 apt remove --purge foo...)

나는 똑같은 오류를 겪었고 동일한 결과로 대부분의 단계를 시도했습니다. 다음은 마침내 나를 위해 일했습니다.

apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5

그 후 mysql이 정상적으로 설치되었습니다.

나는 어떤 경우인지 확신하지 못했지만 다른 솔루션은 작동하지 않아 오류가 계속 발생했습니다. 나는이 시도 apt-get purge mysql-*후, autoremove하고 autoclean. 그 후 설치에 문제가 없었습니다.

**

위의 명령으로 데이터베이스를 삭제할 수도 있습니다.

**

방금 달리면

sudo apt-get update
sudo apt-get install mysql-server

그것은 mysql을 업데이트하고 이것은 16.04lts로 업데이트 한 후 발생했던 문제를 해결했습니다.

아니면 그냥 실행

sudo apt-get install lamp-server^

모든 서버 패키지를 업데이트합니다.

MySQL 5.7 버전의 경우 앞에서 설명한대로 MySQL을 제거했습니다.

sudo apt purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo rm -rf /var/lib/mysql*

그리고 도움으로 설치했습니다 :

sudo apt-get update
sudo apt-get install mysql-server
mysql_secure_installation

모든 것이 작동하는지 테스트하려면 :

systemctl status mysql.service

기본 우분투 저장소에서 phpMyAdmin을 설치하십시오. 그런 다음 다음을 실행하십시오.

dpkg --configure mysql-server-5.5
apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
apt-get autoremove
apt-get autoclean
apt-get update
