Fail2ban no pudo iniciarse en Centos 7. Falta el archivo /var/log/secure

Hace unos días compré vps e instalé Centos 7. Ahora estoy intentando configurar fail2ban para ssh. Instalé epel-release. Iptables estaba en uso por defecto. Esto es lo que obtengo cuando intento iniciar fail2ban:

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

Intenté reinstalar iptables, pero aún así, después de una nueva instalación, me falta el archivo de registro seguro. ¿Puede deberse a la configuración del proveedor de vps?

Respuesta1

¿Por qué no crear el archivo que falta?

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

Entonces:

systemctl restart fail2ban.service

/var/log/secureviene de rsyslog. Asegúrate de tenerlo authpriv.* /var/log/secureinstalado /etc/rsyslog.confy rsyslogen ejecución:

systemctl status rsyslog
