Centos6.5 usa o pacote rpm para instalar o MySQL8.0.22. Após a instalação ser concluída, o erro de inicialização do banco de dados é relatado: Falha ao abrir o arquivo de bootstrap /var/lib/mysql-files/install-validate-password-plugin.2SvMB2 .sql
Observe o log primeiro, o erro específico é o seguinte:

O servidor não instalou o MySQL antes e foi iniciado diretamente sem modificar nenhuma configuração padrão após a instalação. Eu também estava confuso.
Então, vários Baidus ainda não conseguiam encontrar a resposta. Por fim, verifique o registro de instalação para encontrar o problema, da seguinte maneira:
