먼저 이 명령어를 실행하신 뒤에…

[code:1mcgaug8]
$ sudo dpkg --configure -a
[/code:1mcgaug8]

그래도 mysql이 정상 동작하지 않거나 하면 재설치를 하세요

[code:1mcgaug8]
$ sudo apt-get --yes autoremove --purge mysql-server-5.5

$ sudo apt-get --yes autoremove --purge mysql-client-5.5

$ sudo apt-get --yes autoremove --purge mysql-common

주의 : 기존에 사용하던 db가 있다면 먼저 백업 후 진행하세요

$ sudo rm -rf /var/lib/mysql /etc/mysql ~/.mysql

주의 : 기존에 사용하던 db가 있다면 먼저 백업 후 진행하세요

$ sudo deluser mysql

$ sudo apt-get autoclean

$ sudo apt-get update && sudo apt-get upgrade

$ sudo apt-get install mysql-server-5.5 mysql-client-5.5
