Centos6.5 usa el paquete rpm para instalar MySQL8.0.22. Una vez completada la instalación, se informa del error de inicialización de la base de datos: No se pudo abrir el archivo de arranque /var/lib/mysql-files/install-validate-password-plugin.2SvMB2 .sql
Primero mire el registro, el error específico es el siguiente:
# 安装完成后，启动报错

El servidor no ha instalado MySQL antes, y se inició directamente sin modificar ninguna configuración predeterminada después de la instalación. También estaba confundido.
Entonces, varios Baidus aún no pudieron encontrar la respuesta. Finalmente, verifique el registro de instalación para encontrar el problema, de la siguiente manera:
