Mysql quebrado (14.04 - 16.04)

Question

Então eu atualizei o Ubuntu de 14 para 16 e agora o mysql-server está quebrado (iF). Eu tentei muito do que foi postado aqui, mas nada disso resolveu o erro.

O que eu tentei:

- > removendo todos os pacotes mysql limpando-os (dpkh -l | grep mysql)

- > procurando por arquivos de configuração "perdidos" (find / -name " my.cnf ")

- > reinstalando o servidor mysql

- > link

Answer 1

Portanto, esta é uma solução rápida e suja:

Como os dados armazenados no mysqldatabase não eram tão importantes, eu removi tudo de arquivos de configuração para bancos de dados em "/ var / lib / mysql / *". Agora tudo funciona de novo, então eu suponho que o erro deve estar em algum lugar em "/ var / lib / mysql / *". Não consigo reproduzir o erro (e não quero mexer no sistema novamente), portanto:

TL; DR: apague tudo e instale novamente
