O serviço MySQL não inicia no problema Ubuntu 16.04 pam_unix

Question

O MySQL Community Server 5.7 (instalado via apt) é executado em um servidor virtual hospedado, o serviço só é reiniciado com sucesso quando eu reiniciar o servidor. Mas, mesmo assim, o serviço mysql não é iniciado ocasionalmente.

journalct -xe mostra:

Nov 16 15:10:58 Ubuntu-1604-xenial-64-minimal systemd[1]: mysql.service: 
Main process exited, code=exited, status=1/FAILURE

Então diz:

[...] vsftpd[4760]: pam_unix(vsftpd:auth): check pass; user unknown
[...] vsftpd[4760]: pam_unix(vsftpd:auth): authentication failure; logname= uid=0 euid=0 tty=f

Não tenho ideia para que esta mensagem aponta.

Preciso editar o serviço ou o script init.d? Alguém com mais conhecimentos de linux sabe como consertar esse comportamento?

    

Answer 1

Você está usando "vsftpd"?

Talvez, se você removê-lo, não tenha mais o problema

sudo apt-get remove vsftpd
