Fail2ban falhou ao iniciar no Centos 7. Arquivo /var/log/secure ausente

Há alguns dias comprei o vps e instalei o Centos 7 nele. Agora estou tentando configurar o fail2ban para ssh. Eu instalei o epel-release. Iptables estava em uso por padrão. Isso é o que recebo quando tento iniciar o fail2ban:

 Job for fail2ban.service failed because the control process exited with error code. See "systemctl status fail2ban.service" and "journalctl -xe" for details.

Depuração do início do fail2ban:

Tentei reinstalar o iptables, mas mesmo assim, após uma nova instalação, estou perdendo o arquivo de log seguro. Pode ser causado pelas configurações do provedor VPS?

Por que não criar o arquivo ausente?

touch /var/log/secure
chown root. /var/log/secure
chmod 0600 /var/log/secure

Então:

systemctl restart fail2ban.service

/var/log/securevem de rsyslog. Verifique se você está authpriv.* /var/log/secureconectado /etc/rsyslog.confe rsyslogem execução:

systemctl status rsyslog
